4 ways to avoid getting caught in email spam filters


You’ve put a lot of time and energy into perfecting the messaging for your mail campaigns and email blasts, but that still doesn’t guarantee that your content will make it into your subscribers’ inboxes. Improve the chances of your mailing deliverability with some of the subject tip lines we’ve provided below, and download our free Spam Triggers tip sheet for an extensive list of words to avoid using in your Subject Line and Email body.

Avoid spelling mistakes & typos

Proofread your email subject line and body and ask a co-worker to take a glance as well. A well-written, error-free mailing subject adds to your brand’s credibility and professionalism. This can decrease your chances of getting caught in a spam filter and boost potential for a higher open rate.

Don’t use ALL CAPS

The use of ALL CAPS in your subject line can not only trigger spam filters in most email services, but it rarely has the intended effect. While you may think you’re catching a subscriber’s attention and standing out from the other items in their inbox, that’s not necessarily a good thing. ALL CAPS can come across as shouting at your recipient and the sight of such a subject line often causes suspicion that the mailing might be a phishing attempt. It’s best to avoid this tactic altogether.

Run an email Health Check

Use the Health Check feature in ENGAGE Email before sending your mailing. If you’re using our ENGAGE Email solution, take advantage of the Health Check feature when scheduling your next email send. It will score your message’s deliverability based on multiple factors and will provide suggestions for improving the chances that your message will make it through various spam filters.

Limit words and phrases that trigger spam filters

If possible, refrain from the use of words and phrases in your subject line and email body that can trigger the spam filters of various email services.
