Thunderbird

Thunderbird is one of the oldest open-source email clients in the world. Its first version was released in 2003, but in the early 2010s, the foundation began to deprioritize the application's development, eventually reaching a 0.08% market share against giants like Gmail and Outlook. However, Thunderbird announced in 2022 on its official blog that MZLA Technologies Corporation would continue with the project, including updates, a new design, and a mobile version.

And this is the one that concerns us here, the Android version, with which you can manage your email addresses. The application is one of the organization's top priorities, as hundreds of millions of people check their email from their smartphones or tablet.

From Thunderbird, you can simultaneously synchronize email from several platforms, viewing emails —received, sent, deleted, drafts, etc. You can reply, forward, archive, send to spam or delete all emails from the same interface, as well as manage an address book with all the contacts to send emails to. You can also apply filters to find specific emails.
