Postden's inbox: all inboxes in one list, with three unread messages.

Features

Built for reading, writing and sending mail.

  • HTML compatibility check

    Write in HTML and see, before you send, which parts Gmail, Outlook, Apple Mail, Yahoo and Thunderbird won't show.

  • Any mailbox

    IMAP and SMTP with your own credentials, or sign in with Google. No app passwords.

  • Safe HTML mail

    Remote images and scripts never load, so senders can't tell when you've opened their mail.

  • Open source

    MIT licensed. Read the code, or build it yourself.
