Spam word checker
Paste your email copy. Get a real-time list of spam trigger words that push messages into the Promotions tab or Spam folder. 120+ patterns covering subject, body, and CTA text.
Every major email provider runs content filters that look for patterns associated with spam. Words like free, guaranteed, risk-free, act now, 100%, winner, congrats, and $$$ aren't banned, but every one of them raises your message's spam score. Cross the threshold and you land in the Promotions tab. Cross it a lot, and you're in Spam.
Filters don't just look at single words. They look at combinations (free + limited time + click here), casing (ALL CAPS is penalized), punctuation (!!!), and ratios (heavy promotional language with no brand voice). This checker flags the obvious triggers so you can rewrite before send.
This is one pre-flight check. Draftship runs 35 of them, live, in the editor.
Subject length, spam triggers, contrast ratios, Gmail clipping, alt text, undeclared variables, CAN-SPAM footers. All audited as you build. Open the editor and ship an email that passes every check.
The long version
- Why your email lands in Gmail's Promotions tab (and the moves that change it)
Promotions is not spam. It is a sorting tier where 60% of marketing email goes by default and engagement runs half what it would in Primary. Here is what Gmail looks at, the levers that actually move messages between tabs, and when Promotions is the right destination.
- Gmail and Yahoo's bulk sender requirements: what passes, what fails, what nobody told you
If you send more than 5,000 messages per day to Gmail or Yahoo personal addresses, you have to pass a short list of checks. The list is short. The enforcement is uneven. Here is the operational guide your ESP did not give you.
