Questions about Free Email Test

Do I need an account?

No. The free test runs without signup. Create a free account to keep history and run 5 scans per month.

Is it the same as an inbox placement test?

No. The free test analyses one email's technical and content signals. Inbox Placement Tests send to real mailboxes at each provider and report where your email actually lands.
