1. AVOID WORDS THAT TRIGGER SPAM FILTERS

First, you must dodge the dreaded spam filters built in to your recipients' firewalls and email programs.

Ever vigilant, spam filters scan each email subject line and compare it to a database of characters, phrases, and words (even combinations of words) on their spammer tag and trash list. If your subject line breaks a spam filter rule, your email is toast.

Check out Hubspot's ultimate list of spam trigger words and phrases. Most of the listed terms are obvious, but you wouldn’t use those anyway, right? Some terms on the list, however, are less obvious...

2. AVOID OTHER VIOLATIONS THAT TRIGGER SPAM FILTERS

Besides using no-no words and phrases, there are other infractions that can get your email sliced and diced by spam filters:

  • Repetitive characters: $$, !!!, …, ???, www
  • Words in all caps: NICE TO MEET YOU
  • Capitalized abbreviations and acronyms: LOL, RSVP, OMG, SPCA, BBB, ESPN
  • Sending the same subject line to a recipient over and over again
  • Anything price related: $199, half off, buy one get one free
  • Anything product spec related: Samsung LCD Monitor 42", iPad 3 64GB
  • Typos, spelling errors, and incorrect grammar
