For reading and writing emails, Tails includes Icedove.
For trademark reasons, Icedove is the name of Mozilla Thunderbird in Tails and they are otherwise the same program.
Tails has replaced Claws Mail with as its email client in version 1.8.
If you have been using Claws Mail and activated its persistence feature, follow our instructions to migrate your data to Icedove.
To start Icedove choose .
You can activate the Icedove persistence feature to store your emails and settings across separate working sessions.

Configure an email account
It is impossible to connect to email providers that require the OAuth authentication mechanism such as GMail or Mail.ru
When starting Icedove for the first time, an assistant appears to guide you through the process of configuring Icedove to access your email account.
To start this assistant again in the future from the main window of Icedove, choose and then from the Account Settings dialog choose Account Actions ▸ Add Mail Account….
Enter your name, email address, and password into the corresponding fields.
The assistant tries to configure automatically the correct parameters to connect to your email provider based on your email address.
If the automatic configuration fails, consult your email provider about how to configure your email account manually.
If the automatic configuration succeeds, you might have to specify which protocol to use to connect to your email provider, either IMAP or POP.
With IMAP, Icedove constantly synchronizes with the server and displays the emails and folders that are currently stored on the server. IMAP is better suited if you access your emails from different operating systems.
With POP, Icedove downloads the emails that are in the inbox on the server and possibly deletes them from the server. POP is better suited if you access your emails from Tails only and store them in the persistent storage.
To know more, see also this comparison between POP and IMAP by Riseup.
OpenPGP encryption with Enigmail
Icedove in Tails includes the Enigmail extension to encrypt and authenticate emails using OpenPGP.
To configure Enigmail for your email account, you can start the Enigmail Setup Wizard by choosing .
You can also create an OpenPGP key associated with your email address as part of the Enigmail Setup Wizard.
If you are new to OpenPGP, you can read the following guides on getting started with encrypting emails using Icedove and Enigmail:
Enhanced privacy with TorBirdy
Icedove in Tails includes the TorBirdy extension for additional privacy and anonymity.
Sending emails in HTML format is disabled by TorBirdy. Emails received in HTML format are displayed in plain text and can become harder to read.
