Before you begin, you need a different, unique email password for any third-party applications, such as Outlook, Apple Mail, or the default email app on your phone. These can be generated from your webmail access.
IMAP
| Server | imap.fastmail.com |
| Port | 993 |
| SSL/TLS Encryption | Enabled, but not STARTTLS |
| Username | Your full email address |
| Password | Your app-specific password |
| Root folder/IMAP path prefix | (leave blank) |
| Folder separator | / (forward slash) |
Do not enable secure password authentication (SPA). It is not needed when you use SSL/TLS encryption and it will not work.
SMTP
| Server | smtp.fastmail.com |
| Port | 465 |
| SSL/TLS Encryption | Enabled, but not STARTTLS |
| Authentication | PLAIN |
| Username | Your full email address |
| Password | Your app-specific password |
If your client supports STARTTLS only, you can use port 587 with STARTTLS enabled.
You may opt to use the email app from our provider instead of the default email app on your phone. This will automatically use all the settings you need. You only need to enter your email address and the master password.
