202 email spam trigger words that will get you in trouble

Avoid these 202 email spam trigger words

Spam filters are designed to remove junk out of your customers’ inboxes, but they’re sometimes so good that they may sweep away your valuable emails, too. You can’t afford to let your emails get flagged as spam, so keep reading.

The easiest way to avoid spam filters is by carefully choosing the words you use in your email’s subject line. Typically, these words can be grouped into these 6 broad categories:

  • Manipulative: creating unnecessary urgency or pressure
  • Needy: sounding desperate or exaggerated claims
  • Sleazy: being too pushy
  • Cheap: no pre-qualifications, everybody wins
  • Far-fetched: statements that are too good to be true
  • Shady: ethically or legally questionable behavior

We’ve compiled a list of 202 spam trigger words you should avoid the next time you sit down to write an email subject line. It’s important to note that while a single incidence of these words may not be enough to trigger the spam filter gods, they should nevertheless be used judiciously.

Manipulative words and phrases

There is nothing wrong with urging your reader to take action, but spam filters often penalize emails with subject lines that create unnecessary urgency and pressure. If everything you send is “urgent,” then nothing is, at least in your recipient’s mind. On the other hand, if there’s enough value in what you have to offer to your readers, urgency will happen organically. In the meantime, avoid using the following spam trigger words:

1. Act now

2. Action

3. Apply now

4. Apply online

5. Buy

6. Buy direct

7. Call

8. Call now

Needy words and phrases

Your email subscribers are looking for immediate value when they see your subject line; they want to know exactly what they’ll get when they click on your email.

Sleazy words and phrases

Cheap words and phrases

One thing to keep in mind when offering something is that the more available it is, the lower its perceived value. In other words, people want what they can’t have. So if your subject lines comprise pre-qualification phrases such as “Congratulations!” or have an “everybody wins!” vibe to them, your email is likely to end up in spam. Instead, avoid the following spam filter words and try to position your value proposition in a way that makes the prospect chase you:

63. Acceptance

64. Access

65. Avoid bankruptcy

66. Boss

67. Cancel

68. Card accepted
