Will this email land in spam?

Paste the subject and body. We find the words, links and leftovers that make filters and readers distrust it, and tell you what to change.

Checked in memory. We do not store or log your email.

What we check

  • Leftover template syntax

    Unfilled {{first_name}} tags and spintax like {Hi|Hello} that reached the body.

  • Trigger phrases

    Money claims, false urgency, too-good promises and phishing words, matched as whole words.

  • Subject line

    Fake Re: or Fwd:, capital letters, exclamation marks, emoji and length.

  • Links

    URL shorteners, links to IP addresses, link text that hides the real domain, and too many links.

  • Linked domains

    Each linked domain is checked on SURBL and URIBL, where they answer.

  • HTML

    Hidden text, tracking pixels, and mail that is mostly images.

Content is half of it

Clean words still land in spam when SPF, DKIM or DMARC is broken, or a sending IP is on a blocklist. Check the domain you send from.
