Type your email address and get the incoming and outgoing server settings to add it to Outlook, Apple Mail, Thunderbird or any other app — including custom and work domains.

Only the part after the “@” is used for the lookup. Nothing you type is stored.

Settings for fastmail.com

Fastmail

Checked against Fastmail’s own help pages

IMAP Incoming

Server: imap.fastmail.com
Port: 993
Encryption: SSL/TLS

POP3 Incoming

Server: pop.fastmail.com
Port: 995
Encryption: SSL/TLS

SMTP Outgoing

Server: smtp.fastmail.com
Port: 465
Encryption: SSL/TLS
Alternative: Port 587 with STARTTLS

Username: Your full email address
Password: An app password — Fastmail doesn’t accept your regular password in email apps.

Don’t turn on Secure Password Authentication (SPA) — it isn’t needed with SSL/TLS and won’t work.
If your network blocks these ports, Fastmail offers proxy servers (imaps-proxy, pops-proxy, smtps-proxy.fastmail.com).
