Proton Mail v3.12 Release Notes

Share this page

Proton’s secure business email plans have been updated, so the following information is no longer accurate. Please contact the Proton for Business team if you have any questions.

Proton Mail 3.12 adds support for encrypted contacts, plain text sending, and Proton VPN for businesses.

Note: Due to the way we roll out new versions, Proton Mail 3.12 has not been released to everyone yet. If you do not see it yet, you will see it soon.

We’re happy to add another critical feature to your secure inbox, encrypted contacts with additional fields. Paving the way for full PGP interoperability, encrypted contacts allows you to protect the details of your contacts with zero-access encryption.

Encrypted Contacts

Contact information, in particular, contact details can be very sensitive. With Version 3.12, we are introducing a full contacts manager that is vCard compatible and can support additional fields. While previously, Proton Mail contacts only saved the name and email address of your contact, our new contacts manager allows you to save additional fields such as phone numbers, addresses, and even custom fields.

Any details saved inside the advanced contact fields (inside the box with the lock icon) is encrypted such that even Proton Mail cannot access this data and can never share it with any third parties. We have also added digital signatures to contacts so that you can verify the integrity of the contacts data.

Encrypted Secure Contacts

Improved Contacts Import and Export

It is now simple to import your contacts from other email providers, such as Gmail, Outlook, Yahoo! Mail, into your Proton Mail account. Proton Mail supports imports of CSV as well as vCard files. When exported, contacts are downloaded in a vCard file containing all the existing contacts.

Download All Attachments

Downloading many attachments within a single message can become laborious. Download All, allows you to download them all with one click. Please note that all attachments will be downloaded as a .zip archive. This feature only works for attached files, if you see attachments that are actually inline images, they will not be downloaded.

Plain Text composing and sending

Plain text sending now provides the option to send messages without any formatting. Simply select Plain Text from the drop down within the composer.

Advanced Editor

We have also enhanced the Proton Mail composer to support more advanced functionality. Now it is possible to change the font, font size, as well as the the font color and background color. This functionality is also now present in the editor when you are editing your email signature.

Improved composer auto-save

Proton Mail has supported auto-save in the message composer since the 2.x release, but in this version, we have improved it so that when you are writing in the composer, the time of the last auto-save will be displayed and automatically updated each time the composer auto-saves the email while composing.

Added Proton VPN for businesses

Back in June 2017, we launched Proton VPN, the world’s first unlimited free VPN service. Along with the free VPN service, we also launched a paid VPN service with higher speeds, enhanced security and privacy features, with support for file sharing and more devices.

With Proton Mail 3.12, we are extending Proton VPN to businesses who already use Proton Mail Professional to secure email for their organization. Now, when you select a Proton Mail Professional plan, you can also add a customized Proton VPN Plus plan. Whereas the standard Proton VPN Plus plan includes support for 5 devices/connections, Proton Mail Professional users can now select as many connections as desired.

You can now add up to 100 Proton VPN connections to your Proton Mail Professional plan, and account admins can allocate these connections to individual users in your organization. This way, not only can you have encrypted email for your entire organization, it is also possible to offer VPN protection to every person on your team.

Proton Mail does not show advertisements or abuse your privacy to make money. Paid accounts are our only source of funding. Please consider upgrading to a Proton Mail Paid account so that we can continue to operate the service and fund further development.
