Editor’s note: Spam filters are much more sophisticated than the subject line triggers listed in this post. For a more up-to-date guide to email marketing, check out our free guide to creating email newsletters, which are actually read here.
Writing the subject lines for your emails can be one of the most stressful steps in email marketing. Is it engaging? Too short? Too long? Too boring? Is that why people are going to hit “delete”? Or will they open it? Will it even reach them or trigger SPAM filters? It is the last of these problems that we can help with today.
SPAM filters can be triggered for various reasons, so that your e-mail skips the inboxes of the recipients and lands directly in their SPAM box. One of the easiest ways to avoid SPAM filters is to carefully choose the words that you use in the subject line of your email. Trigger words are known to cause problems and increase the likelihood that your email will fall into a SPAM trap. By avoiding these words in your email subject lines, you can dramatically increase your chances of going beyond SPAM filters.
The next time you sit down to write an email subject line, read the full list below and make sure you don’t use words that could get you in trouble. You may want to bookmark this list so that you can refer to it every time you compose an email subject line. Back, SPAM filter!
