What Are Spam Trigger Words?
Spam trigger words are words and phrases that spam filters associate with promotional, scammy, or deceptive email—things like "free," "act now," "guaranteed," "risk-free," and "congratulations." Each one adds a little risk. Rule engines like SpamAssassin assign weighted points to known patterns and flag the message once the combined score crosses a threshold. The full list, grouped by category, is right below—skip ahead if that's what you came for.
The important nuance: no single word sends your email to spam. "Free consultation" in a normal business email is fine. The damage comes from stacking—several trigger words together, amplified by ALL CAPS, exclamation marks, and money symbols. Filters score combinations and context, not isolated vocabulary.
How to use this list
- As a pattern guide, not a banned-word ban. The categories matter more than any one word—learn the patterns filters dislike.
- To spot stacking. One or two words from one category is normal copy; five from three categories is a spam profile.
- Not as a substitute for testing. Filters retrain constantly—always confirm with a spam word checker that scores your real message.
If you want the mechanics of how filters score a message and read the report, see our email spam checker guide and what is spam score. This page is the word list itself.

Formatting that acts like a trigger word
These aren't words, but filters score them the same way—and they amplify every trigger word in the message:
- • ALL CAPS words or subject lines
- • Multiple exclamation marks!!! or excessive punctuation???!!!
- • Money symbols: $$$, £££, €€€
- • Fake reply prefixes: "Re:" or "Fwd:" on a first-contact email
- • Image-only emails with almost no text, or hidden white-on-white text
- • URL shorteners and mismatched / cloaked link domains
Don't memorize this—score your draft
No one writes well with a banned-words list open. Write your email naturally, then paste it into our free checker to see exactly which words and formatting fired, and how many points each one cost.

You rarely need to cut an idea—just phrase it like a human instead of a billboard. Here are common triggers and lower-risk alternatives that keep the meaning:
| Trigger phrase | Say this instead |
|---|---|
| 100% free | Included, no charge, on us |
| Act now / Order now | Get started, Book a time |
| Limited time offer | Available through Friday |
| Guaranteed / Risk-free | Backed by a 30-day return |
| Click here | Descriptive anchor text (e.g. "view the pricing") |
| Cheap / Lowest price | Affordable, starts at $X |
| Increase sales / Grow your business | A specific, measurable outcome |
| Congratulations, you've been selected | Use the recipient's name and real context |
| Dear friend / Dear valued customer | Hi [First name] |
The pattern: replace hype with specifics. A concrete number, a real date, or the recipient's actual name reads as legitimate to both the filter and the human.
Spam Trigger Words in Subject Lines
The subject line is the first thing both the filter and the recipient judge, so the same trigger words read as riskier here—and a few formatting habits are near-instant flags.
Avoid in subjects
- • Free, win, winner, cash, prize
- • Act now, urgent, limited time, expires
- • Congratulations, you've won, claim now
- • ALL CAPS words, $$$, multiple !!!
- • Fake "Re:" / "Fwd:" prefixes
- • Misleading claims the body doesn't back up
Do instead
- • Describe the actual content, plainly
- • Use the recipient's name or company
- • Keep it under ~50 characters
- • Sentence case, no symbol spam
- • Make the subject match the body
- • Ask a specific, relevant question
One caveat that surprises people: a deceptive subject line is also a CAN-SPAM violation, not just a deliverability risk. Subject and body have to match. See our email compliance guide for the legal side.
How to Use a Spam Word Checker
A spam word checker scores your real message instead of making you guess from a list. Paste the subject and body in, and it runs the content through a SpamAssassin-style rule engine, returning every word and formatting issue that fired with the points it added. Here's the workflow that actually fixes deliverability:
1Write naturally first
Don't self-censor every word as you draft—you'll write stilted copy. Get the message down, then check it.
2Paste it into the checker
Run subject and body through Enrichley's free spam word checker. No signup—you get an itemized report in under a minute.
3Fix the high-point items first
Not every flag matters equally. Use the swap table above to rephrase the words that cost the most points, and ignore the trivial ones.
4Re-check, then send a seed test
Re-run until the content score is clean, then send to a few seed inboxes (Gmail, Outlook, Yahoo) to confirm real placement. The full method is in our email spam checker guide.
Free spam word checker, no signup
Paste your subject and body, get an itemized report of every trigger word and formatting issue that fired—and the points each cost.
Check spam words nowWhy Word Choice Isn't the Whole Story
Here's the honest part most word lists leave out: in 2026, trigger words are the smallest lever you have. Gmail, Outlook, and Yahoo lean far harder on sender reputation, authentication, and engagement than on vocabulary. You can write a perfectly "clean" email and still land in spam if these are broken.
Authentication (the biggest fixable lever)
SPF, DKIM, and DMARC that align with your sending domain. A missing DKIM signature hurts more than a dozen trigger words. Gmail and Yahoo also require a List-Unsubscribe header for bulk senders.
List quality & sender reputation
Sending to invalid or stale addresses causes bounces and spam-trap hits that wreck reputation far faster than any wording. Verifying your list before each campaign removes the addresses that drag you down. See what email verification is and how to check for blacklisting.
Engagement
Opens, replies, and "not spam" actions teach filters you're wanted. Pruning subscribers who haven't engaged in months lifts your aggregate rates and pulls future sends out of the spam folder.
The full picture
Think of trigger words as the last 10% after the fundamentals are in place. Fix authentication and verify your list first; then clean up the wording. For how the whole score is calculated and read, see what is spam score.
