- Authenticate properly: SPF, DKIM and a DMARC policy on the sending domain.
- Send from a subdomain you warm up gradually rather than blasting from day one.
- Suppress unsubscribes, bounces and long-term non-openers automatically.
- Include a plain-text alternative and a working one-click unsubscribe header.
- Write like a person: fewer links, less shouting, one clear call to action.
Frequently asked questions
What are spam trigger words?
Words and phrases — usually about money, urgency or guarantees — that spam filters have learned to associate with unwanted mail. On their own they rarely block a message, but combined with poor authentication or low engagement they push you into the junk folder.
Will removing spam words guarantee inbox placement?
No. Content is a small part of the score. Authentication (SPF, DKIM, DMARC), sender reputation, list hygiene and recipient engagement matter far more.
Are exclamation marks and all-caps really a problem?
Yes, in volume. Repeated punctuation, shouted words and excessive links are classic promotional patterns that filters weigh together with everything else.
Does this send my email anywhere?
No. The scan happens entirely in your browser — your copy never leaves the page.
