Avoiding the Spam Folder: 175 Email Trigger Words & Phrases That’ll Land You in Spam

Ask any marketer what they dislike the most about email marketing and you’ll likely hear something about filters and the dreaded spam folder. We get it. It can be frustrating—after spending countless hours crafting the perfect email and clever subject line, having your email land in the spam folder is a tough pill to swallow.

If this has happened to you don’t feel bad—20% of the time emails land in the spam folder. That’s why email experts often urge marketers to spend just as much time crafting a great subject line as you’d spend writing the body copy of an email to avoid getting filtered out.

To help combat this occurrence, we’ve compiled a list of spammy words and phrases that can trigger spam filters to help you avoid the spam folder. Welcome to your ultimate “spam folder avoidance” guide.

Spam filters will often check for red flags like:

• The use of certain words (see our comprehensive list below)
• Links to sketchy or fraudulent websites
• Messages in ALL CAPS or punctuation overkill, such as !!!!!!!! or ?!?!?!?!?!
• Colorful, different sized fonts
• Broken HTML code or poorly designed emails
• Emails without an unsubscribe button
• Odd personalization practices, such as “My Dear” or “Hi Friend”
• Purchased third-party send lists

The Cardinal Rule of Subject Lines

“If it sounds too good to be true it probably is” is the cardinal rule to keep your emails out of the spam folder. When you’re writing subject lines, it’s important to avoid words and phrases that sound like clickbait.

Here are some examples of things to avoid when crafting your subject lines:

• Over-promising, sensationalizing, or making exaggerated claims like offering “free gifts”
• Coming across as unethical or sounding like a scam
• An “everybody wins” approach that sounds too good to be true or gimmicks
• Using strange formatting in an attempt to stand out in a jam-packed inbox
• Being too pushy, using manipulative language

Now that we’ve highlighted the basic best practices, here’s a list of words and phrases that have been known to trigger spam filters. While this list isn’t exhaustive (sadly, it’s always growing), it is a great point of reference you should bookmark in order to craft the perfect subject line, optimized to bypass the spam filter.
