Your email isn't bad.
It's just going to spam.
Find out why in about 20 seconds. We check your DNS, authentication, blacklists, sending server, headers and content, then tell you exactly what to fix.
We give you an address. You send it a normal email from the tool you actually use (Gmail, Outlook, your newsletter platform, your app). We grade what arrives: SPF, DKIM, DMARC alignment, your sending IP, headers, content and SpamAssassin.
