Most email issues are quick to resolve once the cause is identified. Below are the most common problems and what to check first.
I Can’t Log In
Start by checking:
- That you’re using the correct login page, you can login via https://mail.arcanemail.net
- That your email address is entered correctly
- That your password is accurate
If you’ve forgotten your password, use Fastmail’s password recovery tools. If you’re locked out entirely, submit a support ticket.
Email Isn’t Sending or Receiving
Common causes include:
- Incorrect password saved on a device
- An email app that hasn’t been updated
- Internet connectivity issues
Try logging in via Fastmail webmail. If email works there, the issue is usually device-specific.
Email Is Going to Spam
