IncaMail is available in German, French, Italian, English, Dutch and Romanian. You can change the language in the settings at any time. Confidential e-mails are displayed in the language you have selected.
Newsletter
You can choose whether you would like to receive the IncaMail newsletter. The newsletter is published four times a year, providing news and other information relevant to IncaMail.
Messages
You can configure different settings for sending IncaMail messages:
- Configure signature: set an automatic signature which is inserted into every e-mail.
- Envelope message: set a customized text which is displayed to the recipient in the e-mail before they open the message. This can include a note on support options or other information. Avoid mentioning any confidential or personal information in this message.
The virtual mailbox provides you with a secure contact form. Share the link to your virtual mailbox with your customers and partners by adding it to a website or automatic e-mail signature. People with access to the link can send you confidential e-mails without registering or paying. Files up to 1 GB in size can also be securely transmitted using the contact form. These files are encrypted and stored on Swiss Post’s IncaMail server. The files are available for download for a maximum of seven days, after which they are irrevocably deleted.
The virtual mailbox is available to Premium or business customers. The costs are invoiced to business customers as per the customer contract. For Premium customers, use of this service is included in the subscription price. The virtual mailbox can be activated and deactivated. It is deactivated by default.
You can set a personalized image or logo and your own text. The image and logo are displayed above the virtual mailbox. Images are automatically scaled to the maximum size of 250 x 150 pixels (w x h). The lower the resolution, the faster the image is displayed. You can also determine whether the sender must enter a spam protection before sending.
You can block receipt of registered IncaMail messages. Click on “Configure ‘Registered’ settings” and follow the instructions. A comprehensive guide can be found here.
You can delete your IncaMail account yourself. To do so, click on “Delete account”. Please note that you will no longer be able to open or read any IncaMail messages you have received once the account is deleted. Deleting an IncaMail account is irreversible.
Information for senders
Dispatch, dispatch types and confirmation of delivery
Writing IncaMail messages
To write a message via IncaMail, click on “Write”.
File types and recipients’ size limits
You can attach files in all standard formats. In order to protect our recipients, file formats with executable code (programs, macros, scripts) may not be sent via www.IncaMail.com. IncaMail permits messages up to a size of 30 MB. However, delivery depends on the maximum size accepted by the recipient. Swiss Post therefore recommends that you query the recipient’s maximum permitted data volume per e-mail. This is particularly advisable for important consignments or consignments subject to a time limit, such as legal documents (mailing option: Registered). It should also be noted that secure transport encryption can double the original size of the message. If an IncaMail message cannot be delivered due to the recipient’s size limit, you will be notified by e-mail.
With the Large File Transfer from IncaMail, customers with a domain connection (MGI) are able to send files of up to 1 GB. Files sent using large file transfer are not located directly within the IncaMail message attachment, meaning they only have a minor impact on message size. More information on large file transfer can be found in the section “Sending large files (large file transfer)”.
Choosing the dispatch type
Select your preferred dispatch type by clicking on the relevant button. Find out more about the different ways of sending mail in the “Dispatch types” section below.
Recipients
You can enter several recipients. Separate them using a “;” (semi-colon), followed by a blank space.
Example: a@domain.ch; b@domain.ch
Sending mail
Click on “Send” to send the message. As no messages are saved in IncaMail, there is no outbox.
Free copy to myself
If you would like a copy for your records, activate the option “Copy to me”. The sent e-mail is delivered to your e-mail address free of charge and in confidential format. You can change the default setting for this option under “Messages” in the settings.
As the sender, you can choose between the following dispatch types:
Confidential message
The message is sent to the recipients in encrypted format, with the option of having a delivery confirmation sent to your e-mail address. To read the confidential message, the recipients must verify themselves by e-mail using a security code. Recipients with a business customer contract receive the message as a normal e-mail via an encrypted connection and can read it without any other precautions. Verification of the postal address is not necessary to receive a confidential e-mail.
Personal message
The message is sent to the recipients in encrypted format, with the option of having a delivery confirmation sent to your e-mail address. To read the personal e-mail, recipients must register once and have their e-mail address verified using an activation code. If the recipient is not yet registered with IncaMail, they will be requested to do so as soon as they attempt to open a personal e-mail. Verification of the postal address is not necessary to receive a personal e-mail.
Registered mail
With the “Registered” dispatch type, senders and recipients are sent a digitally signed PDF receipt as proof that the message has been sent and received. Messages must be accepted by the recipient within 7 days, otherwise they will expire. When calculating the collection period and availability, every day counts, including Saturdays, Sundays and public holidays. This dispatch type can be used for communication with Swiss authorities and complies with the relevant legislationTarget not accessible.
You can find more information in the “Registered mail” section.
IncaMail gives customers who have integrated IncaMail into their e-mail infrastructure (Mail Gateway Integration – MGI) the option of sending large volumes of data via large file transfer. Large volumes of data of up to 1 GB can be sent securely using the IncaMail add-in. No additional costs are incurred through use of the large file transfer service.
You load your files using drag and drop or by clicking on the relevant zone via the secure connection to the IncaMail server. The data is exclusively encrypted and is stored on Swiss Post’s IncaMail server. Please be aware that the files are available for download from the IncaMail server for a maximum of seven days, after which they are irrevocably deleted. Once successfully uploaded, links are automatically generated in the current message, allowing the recipient to download the files. Send your e-mails to your desired recipients as usual securely via IncaMail. Since the files are not directly attached to the e-mail, they only have a minor impact on message size.
Large file transfer (LFT) from IncaMail can also be used as part of administrative proceedings (ECAPO, SR 172.021.2), in civil and criminal processes, and in debt collection and bankruptcy proceedings (VeÜ-ZSSV, SR 272.1) (see IncaMail for public authorities). IncaMail is a secure file delivery platform recognized by the Confederation.
Delivery confirmation
The sender of a confidential or personal message receives delivery confirmation by e-mail as standard. This is issued as soon as the e-mail has been delivered to the recipient’s system. It confirms that the e-mail has been delivered to the recipient’s inbox, but not that the recipient has opened the e-mail. In the settings, you can indicate whether or not you wish to receive the delivery confirmation.
Submission and acceptance receipts
With the “Registered” dispatch type, the sender and recipient are sent various receipts.
You can find more information in the Registered mail section.
The logbook allows you to view information on all the messages that have been sent and received. The logbook does not contain any information about the content of each e-mail. The following overview lists the various IncaMail statuses and their meanings:
IncaMail status | C/P | R | Meaning |
---|---|---|---|
Arrived in IncaMail | Yes | Yes | The IncaMail message has been accepted by the platform but has not yet been delivered to the recipient’s system. If the status remains unchanged for more than two hours, the sender will automatically be informed by the platform. IncaMail will continue trying to delivery the message for a maximum of 72 hours. If the message has not been delivered after 72 hours, the message will be deleted in IncaMail and the sender will be notified by e-mail. The message is assigned the status “Not deliverable”. |
Processed | No | Yes | IncaMail has processed the message and is waiting for acceptance by the recipient. |
Delivered | Yes | No | The IncaMail has been accepted by the recipient’s system. |
Opened | Yes | No | The recipient has opened the IncaMail message and read it via the web interface. (Status not possible for recipients with a “Service integration” business customer contract and the “Confidential” dispatch type. In this case, the status remains set to “Delivered”). |
Not deliverable | Yes | Yes | The IncaMail message could not be delivered for various reasons. The reasons may include: inbox full, target system unavailable, e-mail address unknown. In this case, the sender receives a notification from IncaMail. See also “Arrived in IncaMail”. |
Accepted | No | Yes | The “Accepted” status means that the recipient has accepted the registered IncaMail message. |
Delivery refused | No | Yes | The “Delivery refused” status means that the recipient has rejected the registered IncaMail message. |
Expired | No | Yes | The “Expired” status means that the recipient has neither accepted nor rejected the registered IncaMail message within a period of 7 days. The message can no longer be opened by the recipient. |
System message | Yes | Yes | After delivery of the message, IncaMail received a delivery status message from the recipient’s mail system. This message is forwarded to the sender by e-mail and the message status is set to “System message”. To determine the message status, please note the content of the forwarded message. |
Key:
C = Confidential
P = Personal (systematically delivered as SAFE)

For business customers who have integrated IncaMail into their e-mail client (e.g. Outlook), the logbook is available to users directly in Outlook. The logbook is protected by two-factor authentication. The user must register on incamail.com before they can access the logbook directly from the e-mail client. Sent messages can be blocked from the logbook. All personal and registered messages can be blocked. Confidential messages can only be blocked if the recipient receives the IncaMail message via incamail.com and not via the e-mail client. If a message is blocked, the recipient will no longer have access to it, even if they have already read it.

Information for recipients
Receiving, opening and answering mail
You receive e-mails from IncaMail directly in the inbox of your existing e-mail address. Delete the e-mail only if you are sure that you no longer need it. Swiss Post cannot deliver the message again as no copy is saved. The confidential and encrypted message can be opened in the message using the “Read” button. To ensure the message is displayed correctly, an Internet connection is required.
You can find detailed instructions on opening IncaMail messages using different devices here:
Note:
The message might not contain a “Read” button. In this case, you can open the IncaMail message simply by clicking on the IncaMail.html attachment. If the HTML attachment cannot be opened directly in the e-mail program, save the attachment on the desktop then open the saved version in the browser.
Confidential IncaMail message
After clicking the button “Read”, recipients without an IncaMail account receive a key link by e-mail which enables them to read the message. Recipients with an IncaMail account can open the message using their personal IncaMail password.
Personal IncaMail message
If you are sent a personal message, you will be asked to log in to IncaMail after clicking the button “Read”. After logging in, the e-mail will be displayed in your browser. If you are not yet registered with IncaMail, you must first register once.
IncaMail registered mail
Every valid e-mail address can receive registered messages.
The procedure when receiving a registered message differs from the procedure for other messages as follows.
Collection period:
The message must be opened within 7 days. Once this period has expired, the message can no longer be opened. If you have opened the message during this period, you can view it again at any time.
Acceptance:
When clicking on the button “Read” for the first time, you can decide after logging in whether you want to accept or refuse the registered message. To do so, click on the corresponding button. The sender is notified of your decision with a receipt. The decision can be postponed until a later point within the collection period. Once accepted, the attachment can be reopened without prompting you to make this decision.
Receipts:
For registered messages, submission and acceptance receipts in the form of a signed PDF are delivered to both the sender and the recipient.
Just as it is for IncMail, the security and privacy of its users are at the heart of what Swiss messaging service Threema is all about. This is why IncaMail messages sent by someone with a business customer contract can be received and opened in the Threema App/Threema Web Client and Threema Work.
Here’s how it works:
- Log in to your IncaMail account at incamail.com.
- Go to “Settings” and scroll down to the tab “Threema settings”.
- Next, enter your 8-digit Threema ID and confirm with “Add Threema ID”.
- You will then receive a Threema message with an activation link.
- Click on the link and log on to incamail.com to complete the activation process.
You will be able to view the IncaMail messages you receive both in your incamail.com inbox and in Threema. This works for both Threema and Threema Work.
Please note: You can only receive IncaMail messages in Threema that have been sent by someone with a business customer contract. You cannot respond to an IncaMail message or compose a new IncaMail message in Threema itself. To do this, you can use your IncaMail account on incamail.com as usual.
The IncaMail message is displayed to you as the recipient in your browser. The following options are available for saving the message:
- Forward as a normal e-mail: the message is forwarded as normal and in an unencrypted format. IncaMail cannot guarantee that the information will be protected against access by third parties. The security of the message is your own responsibility.
- Save as an e-mail message (.eml): the message can be saved in the general e-mail client format. Please note that the message is not automatically saved to your e-mail inbox. However, you can open the file with various e-mail clients (e.g. Outlook or Thunderbird).
- Save as a PDF: the message can be saved locally as a PDF.
All you need to do to save files sent using large file transfer is to click on the corresponding links within the message. More information on large file transfer can be found in the section “Receiving large files (large file transfer)”.
You will receive an IncaMail message as usual as a recipient of a large file transfer from IncaMail. Open this as described in the section “Receiving and opening messages”. There will be links in the message which you click on to easily download the sent files.
The links will indicate the title, format and size of the files and show how long they are available for download. Please be aware that the data is available for download for a maximum of seven days after which it is irrevocably deleted.
Clicking on the link takes you to a separate IncaMail website. The file download starts automatically. The file will be on your computer once successfully downloaded, usually under “Downloads”.
You can reply to every IncaMail message once free of charge in the web interface. If you wish to select a dispatch type other than “Confidential” for your reply or add extra recipients, the reply is subject to a fee.
Notifications of IncaMail messages are always provided with a signature for security reasons. Please always check the validity of the signature and the sender. The sender of the e-mail should always be as follows:
Sender: swisspost@im.post.ch
Unfortunately, some e-mail clients and web mailers show the signature to be invalid or unknown, despite the fact that the certificate is valid. In these cases, a manual inspection of the relevant certificate is recommended.
You can find out how to check the signature in the different e-mail clients in the following document entitled “Checking the signature”.
Checking the signature (German version) (PDF, 279.6 KB)[Media | Not Accessible]
The trust level of each sender and recipient is indicated in IncaMail with up to three stars. The stars illustrate to what extent the user’s identity has been checked.
Stars | Trust level | Possible identity checks |
---|---|---|
(none) | Unknown | None or status hidden |
* | Good | Registration, verified data acquisition or similar |
** | Very good | Postal address verification, contract or similar |
*** | Excellent | Personal identification, passport/ID, SwissID or similar |

You have the option of hiding your own trust level in the settings. Users with a hidden trust level receive no information concerning the trust level of their communication partner.
Electronic communication with public authorities via IncaMail
Sending registered mail by e-mail
The ordinance adopted by the Swiss Confederation concerning the electronic transfer of documents within the context of civil and criminal proceedings and debt collection and bankruptcy proceedings and the ordinance for the electronic transfer of documents within the context of administrative proceedings (hereinafter: eGov ordinancesTarget not accessible) oblige courts and authorities to accept submitted documents and to use a secure delivery platform. Similarly, lawyers and parties to the proceedings can indicate that they wish to receive decisions electronically. At the end of 2010, IncaMail was recognized by the Swiss Confederation as a secure delivery platform. The “Registered” dispatch type is designed to ensure that IncaMail complies with the eGov ordinances. All registered IncaMail users with a Premium account or a business customer contract can send registered documents. You can find further information on this in the Registered mail section.
Accounts activated to receive registered mails and Swiss eGov communication must be recorded by IncaMail in the Swiss Confederation’s cross-platform subscriber directory. Other IncaMail users and users of other recognized delivery platforms can search for recipients in this directory.
Interoperability
Registered IncaMail messages are exchanged in an interoperable manner with other platforms recognized by the Swiss federal tax office. If the recipient of a registered message is registered on another platform, the message is transferred to the other platform for delivery. As the sender, you receive the usual digitally signed submission and acceptance receipts from IncaMail.
Note
An unencrypted message can be available on the delivery platform in unencrypted format and can therefore be viewed by service providers or commissioned third parties, even if this prohibited. Users who cannot take the risk of a document being seen must not use the delivery platform or must use additional encryption for the message (e.g. the recipient’s public signature key).
From criteria catalogue V2, section 6.5. Paragraph 2Target not accessible (German version)
Electronic registered mail with IncaMail
Digitally signed acceptance receipt for even more security
With the “Registered” dispatch type, confidential information can be sent via IncaMail in a traceable and encrypted manner. In principle, everyone can receive registered messages via IncaMail and can open the messages they contain within 7 days. The sender and recipient receive signed receipts in PDF format which serve as proof of the transaction. The “Registered” dispatch type can be used in Switzerland to send messages as per the FDJP ordinance concerning the recognition of platforms for the secure delivery of documents relating to legal proceedings (SR272.11).
More specifically, this means that the “Registered” dispatch type can be used for the electronic transmission of documents relating to civil and criminal proceedings, debt collection and bankruptcy proceedings and administrative proceedings.
No. | Step |
---|---|
1 | The IncaMail user sends a registered message via the IncaMail web interface, a business software package or an e-mail client (e.g. Outlook). When sending via the web interface, they can select the recipient from the registered mail directory. |
2 | As soon as the message has arrived in IncaMail, the sender and recipient receive a submission or acceptance receipt in a normal e-mail. |
3 | IncaMail checks whether the recipient has blocked receipt of registered messages. If not, the message is delivered to the recipient. Otherwise, delivery is cancelled and the sender is notified accordingly. |
4 | The recipient receives the message in encrypted format and can perform the following tasks within a period of 7 days: - Accept message: they open the message, confirm acceptance (click on “Accept”) and can thus read the message. - Refuse acceptance: they actively reject acceptance of the message (click on “Refuse acceptance”) and can thus not read the message. - Allow to expire: they allow the 7-day period to expire and thus can no longer open the message. |
5 | As soon as the recipient has carried out an action as per step 4 or the period for opening the message has expired, the sender and receiver are sent another receipt with the corresponding message status. |
Comments:
- Messages as per Swiss communication with authorities intended for registered recipients on other recognized delivery platforms are sent to the corresponding platform for delivery (in step 3).
- Thanks to the “Auto-Accept” option, business customers can automatically accept IncaMail messages.
- If an IncaMail message cannot be delivered (e.g. because it has been rejected by the recipient’s system), the sender and recipient will be notified by means of a normal e-mail and the status of the message will be changed.
To send registered IncaMail messages, senders must satisfy the following minimum requirements:
- Registered IncaMail account with e-mail verification
- Premium account or business customer contract
Registered IncaMail messages can be sent via all existing product variants and to one or more recipients. Every valid e-mail address can be selected as the recipient of a registered IncaMail message.
IncaMail account holders have the option of blocking registered IncaMail messages in the settings. Registered messages can be received via all existing product variants. Once accepted, messages can still be opened by the recipient after the deadline has expired.
Every customer can decide whether or not they want to be registered and visible in the directory for IncaMail registered messages. “Visible” means that other IncaMail customers can look for them in the directory. To participate in communication with Swiss authorities, users must be recorded in the eGov directory Switzerland.
Directory | Description |
---|---|
IncaMail registered message directory | The directory is operated by IncaMail and can only be consulted by IncaMail users. All e-mail addresses can be used as a recipient for IncaMail registered messages. IncaMail customers also have the option of registering for the IncaMail registered message directory so that other users can search for them. |
eGov directory Switzerland | The directory is operated by the Federal Office of Justice in Switzerland. It contains the e-mail addresses of all people registered for communication with the Swiss authorities in accordance with the Ordinance of 18 June 2010 on Electronic Service in Civil and Criminal Proceedings and Debt Enforcement and Bankruptcy Procedures. For further information, see the eGov participant directory. |
The receipts allow senders and recipients to confirm transactions. The receipts are delivered to the sender and recipient by normal e-mail as a PDF file signed by Swiss Post. The receipts contain all key elements of the transaction. They are not saved in IncaMail; storage is the responsibility of the sender and recipient.
The following receipts are created and sent:
Receipt | Event |
---|---|
Delivery receipt | The message has reached IncaMail. |
Acceptance receipt | The recipient has accepted the message. |
Expiry receipt | The acceptance deadline has expired without any action by the recipient. |
Refusal receipt | The recipient has refused delivery. |
In the event of an interoperable transfer via another recognized delivery platform as per communication with Swiss authorities, the receipt may also be sent by the other delivery platform.
The legal effects of IncaMail messages sent and received using the “Registered” dispatch type shall be governed in individual cases by the applicable statutory provisions and judicial and institutional practice of the national jurisdiction responsible for adjudication, as well as any existing private agreements. It is the exclusive responsibility of the customer to undertake due diligence concerning the legal effect and admissibility of electronically transmitted messages in individual cases.
The following facts must apply to IncaMail registered messages to ensure legal evaluation:
- The PDF receipts contain all relevant data and are signed electronically by Swiss Post.
- As an independent third party, Swiss Post can, on request, demonstrate transaction data at any time by means of log files (but not the associated content).
- Transmissions within the framework of the Ordinance of 18 June 2010 on Electronic Service in Civil and Criminal Proceedings and Debt Enforcement and Bankruptcy Procedures comply with this ordinance.
As per the requirements of the Federal Department of Justice and Police (FDJP), we wish to point out that end-to-end encryption of electronic messages is not required:
An unencrypted message can be available on the delivery platform in unencrypted format and can therefore be viewed by the service provider or commissioned third parties, even if this prohibited. Users who cannot take the risk of a document being seen must not use the delivery platform or must use additional encryption for the message (e.g. the recipient’s public signature key).

If this address (instead of the address without the extension) is selected for an e-mail, the recipient automatically receives an IncaMail message, even if the add-in for IncaMail is not open. - C: Prefix in the subject line: The dispatch type is marked in the subject line of the message with a prefix: <c>: Confidential IncaMail message. <p>: Personal IncaMail message. <r>: Registered IncaMail message. This prefix should not be removed. If it is removed, however, the message will be sent as “confidential”.
- D: IncaMail large file transfer: The IncaMail large file transfer feature lets you send large volumes of data via secure e-mails. You can transfer the desired files up to 1 GB in size securely to IncaMail via drag and drop or by clicking on the highlighted zone. Download links are then automatically generated in the current message, which you send as usual via IncaMail to allow the recipient to receive large volumes of data securely. More information on this can be found in the section “Information for senders – how to send large files using large file transfer”.
- E: Logbook: Registered IncaMail users can access the logbook directly from the e-mail client, where they can retroactively block sent messages, for example. You can find more information on the logbook in the “Information for senders – Status / logbook” section.
GDPR-compliant communication
Sending encrypted e-mails with IncaMail
The EU’s General Data Protection Regulation (GDPR) introduces new provisions for handling personal data. IncaMail, the e-mail encryption service from Swiss Post, is key to success in GDPR-compliant e-mail communication.
- GDPR-compliant e-mail security
- Send IncaMail messages directly from your existing e-mail client
- Communicate securely in a verifiable, encrypted manner
The new EU General Data Protection Regulation (GDPR) has been directly applicable since 25 May 2018. It changes provisions concerning the protection and security of personal data, and can affect all companies in the EU as well as a large number of companies from non-EU countries that process personal data. Do you have business relationships with companies in the EU? Do you actively offer products and services to private customers who are domiciled in the EU? Do you send e-mails to partners or suppliers in the EU? If so, you will have to deal with the GDPR. With IncaMail, the service for secure encrypted e-mail correspondence, you can communicate securely at all times directly from your existing e-mail client (e.g. Outlook 2007–2016, Office 365).
The GDPR changes the provisions relating to the protection and security of EU citizens’ personal data. Here are a few of the most important changes:
- If personal data is to be processed, there needs to be legal justification. This could, for example, be fulfilling a contractual obligation.
- For companies, there is an obligation to provide information. If personal data is to be processed, the company must inform the persons affected (data subjects) of the exact purpose for which the data will be used, among other aspects.
- E-mails within the EU containing personal information are to be sent encrypted where possible.
- Obligation to notify: companies need to report data breaches to a supervisory authority. The data subjects need to be informed if the breach is likely to constitute a high risk to their personal rights and freedoms.
- The encryption of e-mails can be beneficial with respect to the obligation to notify: under some circumstances, data subjects do not need to be notified provided the data was encrypted.
Remark: the statements made above are no substitute for legal advice.
Personal data concerns all information which relates to an identified or identifiable natural person and allows conclusions to be drawn concerning this person or their personality, for example:
- Name and date of birth
- Contact information such as postal address, e-mail address, telephone number
- Physical characteristics, e.g. height, weight, hair colour
- Relationships such as those with relations, friends or employers
- Bank account information
The GDPR also defines personal data which requires special protection. The processing of such data is subject to strict requirements. This includes, for example:
- Ethnic background
- Political, religious and ideological opinions
- Health data
- Information on sexual life
- Biometric data which clearly identifies a person
If the processed data features no personal references, processing is generally not covered by the data protection provisions.
The GDPR may affect all companies in- and outside the EU which process personal data relating to EU citizens.
It is advisable to encrypt e-mails if they contain personal data in need of special protection such as political views or health status information. Encrypting e-mails can save companies a great deal of effort and even protect their reputation since any data breaches need to be reported to a supervisory authority. The data subjects also need to be informed if there is a high risk to their personal rights and freedoms. The time-consuming task of notifying the data subjects is in some cases not required if the data was encrypted.
The add-ins provided by IncaMail allow you to communicate in an encrypted, verifiable manner at all times and also feature GDPR-compliant e-mail security directly from your existing e-mail client (e.g. Outlook 2007–2016, Office 365).
