Access your Fastmail Account from an Email Program using IMAP

Fastmail provides IMAP access to your Fastmail account, so you can connect to your email from mobile devices and desktop email clients.


Fastmail supports IMAP / SMTP

This means you don't have to use Fastmail's webmail interface! You can check your email and send messages using other email programs (like Mailspring, Outlook Express, Apple Mail, or Mozilla Thunderbird). Using desktop email applications can improve your workflow. They typically offer more options, and your email is still available on your computer when you're disconnected from the internet.

Setup Your Fastmail Account with Your Email Program Using IMAP

To access your Fastmail email account from a desktop email program, you'll need the IMAP and SMTP settings below:

Fastmail IMAP Server
