Email Delivery Test

A test email is sent to your mailbox so you can see whether it arrives, which folder it lands in, and what its headers look like.

The subject and body are fixed and cannot be changed — this tool exists to test deliverability, not to send arbitrary content.
A maximum of 3 sends per day is allowed for each domain.

What does this tool check?

  • Whether your mailbox accepts or rejects mail from a legitimate sender.
  • Whether the message lands in the Inbox or goes straight to Spam.
  • The real headers of a delivered message, for practice and inspection with the header analyzer.

To test the opposite direction — the sending quality of your own server — use the Mail Tester: you send us an email and we score it.
