Know your spam risk before you send.
Every campaign gets a 1–10 spam risk score before sending. See exactly which phrases are flagged and fix them in seconds — before they cost you inbox placement.
What your score means
The scale runs 1 (clean) to 10 (near-certain spam folder).
Safe to send
No significant spam triggers detected. Ready to send.
Review recommended
Some phrases may reduce deliverability. Review flagged items before sending.
High risk
Multiple spam triggers detected. Resolve before sending to protect sender reputation.
Exact flags, not vague warnings
MoreMail doesn't just give you a number — it tells you precisely what to fix.

What gets checked
Six categories scanned on every campaign before you can send.
Trigger phrases
Words and combinations that Bayesian spam filters are trained on: "FREE!!!", "Act now", "Limited time", "Guaranteed", "Click here".
ALL CAPS sections
Shouting triggers both algorithmic and human spam signals. The checker flags any run of 3+ consecutive uppercase words.
Excessive punctuation
"Don't miss this!!!!!!" reads as spam to filters. Flagged when you have 2+ consecutive exclamation marks or question marks.
Suspicious link patterns
Shortened URLs, mismatched anchor text, and bare IP address links all raise suspicion. Each flagged instance adds to your score.
Image-to-text ratio
Emails that are mostly images with little text are a classic spam tactic. MoreMail checks your ratio and flags anything below 40% text.
Missing unsubscribe
No unsubscribe link is an instant high-severity flag — and a CAN-SPAM / GDPR violation. Caught before you can send.
Why this protects your sender reputation
Once your sending domain gets flagged, recovering takes weeks. Catching triggers before sending is far cheaper than rebuilding a damaged reputation.
