Using Tags and Folders

Tags and folders are the best way to keep your inbox organized. Here are all the different options you have:

• To move an email to a folder, tap and hold on that email. Then tap the “Move to folder” icon at the bottom-left corner of your screen. Select the folder you wish to move your email to.
  

• To assign a tag to an email, tap and hold on that email. Then tap the 3-dots “More” menu at the bottom-right corner of your screen. Select “Tags”, then the appropriate tag. Finally, tap “Save”.
• To find an email that has been moved to a folder or assigned a tag, tap the 3-lines “Menu” icon at the top-left corner of the app. You can then select a specific folder or tag to consult.

• To create a new folder, tap the 3-lines “Menu” icon at the top-left corner of the app. Next to “Folders”, tap the “+” icon. Choose a name and (optionally) a parent folder, then tap “Create folder”.

Encryption and Digital Signatures

Encryption ensures only you and the recipient can read the content of your conversations.

The Mailfence mobile app offers two types of encryption:

• Password encryption (aka symmetric encryption)
• End-to-end encryption (aka asymmetric encryption)

Using password encryption in the Mailfence mobile app

To encrypt an email with a password, start composing a message. Then, tap the “Encryption” icon at the top of the screen.

Next, select “Password protected”. Enter a password, then confirm it.

Do not use your account password or any other password you have already used in the past.

You can also enter a “Hint” that the recipient will be able to read (in case they forget the password). Finally, you can enter an expiry date (up to 4 weeks). After this time, the recipient will no longer be able to access the email.

Using end-to-end encryption in the Mailfence mobile app

Mailfence uses the OpenPGP protocol for its end-to-end encryption. You can learn more about it in this guide here.

To encrypt an email with OpenPGP, start composing a message. Then, tap the “Encryption” icon at the top of the screen.

Next, select “OpenPGP encrypted”. Check your key details, then enter your passphrase. Tap “Enable OpenPGP encryption”.

Digital signatures

To sign an email using OpenPGP, start composing a message. Then, tap the “Encryption” icon at the top of the screen.

Next, select “Signed with OpenPGP”. This will assure the recipient that the email genuinely originates from you, the verified sender, and also confirms that the email has not been altered in transit.

In the near term, we plan to expand the functionalities of the Mailfence mobile app. This will include a fully-featured Calendar, Documents, and much more.
