Email spam checker and copy review in one

Email check scores your cold email out of 100, shows the lines a busy reader will skip, checks the sending domain (SPF, DKIM and DMARC) so it lands in the inbox, and returns a tighter version in your voice.

What does Email check do?Email check scores your cold email out of 100, shows the lines a busy reader will skip, checks the sending domain (SPF, DKIM and DMARC) so it lands in the inbox, and returns a tighter version in your voice.

What you get

  • A score with the reason for every point
  • Weak lines quoted with a fix
  • A deliverability checklist: SPF, DKIM, DMARC, complaint rate
  • A rewrite with word count before and after

What it asks you

Only what your website, CRM and company context cannot answer.

  • Who is the email for?
  • Which domain do you send from?

The method

Read and delivered

An email has to land and then earn the third line. Since 2024 Gmail and Yahoo require authentication, one-click unsubscribe and spam complaints below 0.3 percent from bulk senders. The check covers both halves.

The research behind it: Gmail and Yahoo sender rules
