Is your email deliverability sorted?

This tool isn't quite right for you (and that's good news)

You scanned gmail.com, which is a free consumer email service. Email providers handle all the authentication for accounts on their own domain, so there's nothing to fix at your end.

If you're trying to send from a custom business address like you@yourbusiness.co.uk, you'd need to scan THAT domain, not your provider's. Start over with the right domain below.

If your emails are landing in spam, that's almost always about content (subject lines, links, sending frequency) or your sender reputation, not your DNS records. Save your £79.
