Common mistakes with spam filters

These are the most common mistakes we see new email marketers make, which result in accidental spam filtering.

  • Using spammy phrases, like « Click here! » or « Once in a lifetime opportunity! »
  • Going crazy with exclamation points!!!!!!
  • USING ALL CAPS, WHICH IS LIKE YELLING IN EMAIL (especially in the subject)
  • Coloring their fonts bright red, or green
  • Coding sloppy HTML (usually from converting a Microsoft Word file to HTML)
  • Creating an HTML email that’s nothing but one big image, with little or no text (since spam filters can’t read images, they assume you’re a spammer that’s trying to trick ‘em).
  • Using the word « Test » in the subject line (agencies run into this all the time, when sending drafts to clients for approval)
  • Sending a test to multiple recipients within the same company (that company’s email firewall can only assume it’s a spam attack)
  • Designing HTML email in Microsoft Word, and exporting the code to HTML (that code is sloppy, and spam filters hate it)
  • Share/Bookmark
