Does your sign-up form really work?
A sign-up box can look perfect and still send people nowhere. Get a test address, sign up on your site with it, and we tell you if the welcome email really arrives, how fast, and if it is set up the right way.
1. Which site is yours?
2. Sign up on your site
Go to in another tab and sign up just like a visitor would, using this email address:
Keep this page open. We'll watch our inbox for 15 minutes and show you what arrives.
All done? Please remove from your mailing list so it doesn't count as a real person. We only keep the facts above for 1 day, never the email itself.
Free. No login. 5 tests a day. This is general advice, not a guarantee: we can't see whether your email lands in spam for other people, but the "trusted sender" check is the best sign.
