To help with your newsletter landing in your subscribers’ email box and not be caught in the corporate filter print and put this list of spam trigger words next to your desk.

Email subject lines are one part of the email delivery system. Emails are delivered to inboxes based on the subject lines, content, and sender reputation. Sometimes engagement is even applied to this filter. (Is your reader opening the email)

Filters look at your email as a whole using one spam trigger word. Using words in your subject line and content like “affordable,” or even “thousands,” a few times is too much and will get filtered as spam.

Subject line spam trigger words are also applied to the newsletter content.

Every newsletter email marketer should have a list of spam trigger words next to their desk. A subject line trigger word thrown in every once in a while won’t hurt your delivery rate (if you’re already in good with the local server delivery system), you still need to be practical about finding great synonyms.

Using words like “free” are discouraged and WP Web Wizard recommends not using them, or in combination with other trigger words such as “trial,” “quote,” “sample,” “access,” etc., which can land your newsletter in the junk box or be filter out before it gets into the email box. Using the word “free” typically increases open rates when it does get delivered.  It’s a gamble.

In case you weren’t aware of the way spam filters work is they assign ratings to your email newsletter. Using the word “free” in the subject line with an otherwise perfectly harmless email might be okay if you have a good delivery record with that particular mail server where your sending newsletters.

However, do it again the next day or combine that subject line with an ALL CAPS subject line and use a * to disguise another trigger word within your email, and it could be filtered out or sent to the spam box. Luckily, we provide a spam-checking tool.

WP Web Wizard provides “Mail Tester”.  Look for it at the bottom of your newsletter editor and find the button “How spammy is this newsletter?”  Click the link provided to view your score. You can send me a message or call me if you’re a client should you not understand the scoring.

  • Use links carefully
  • Keep your emails short
  • NO attach files
