157 Words That Will Get Your Emails SPAMMED!


Getting SPAMMED sucks! You spend a lot of time and effort creating personalized and useful content to be delivered via email to your customers only to have it dumped into a SPAM folder. When you see your open rates taking a nose dive, you start to question your whole content marketing strategy. Why aren't people opening my emails anymore? Do they not like the articles? Are they not useful or relevant anymore?

It's possible, but before you start banging your head against the wall, trying to figure out how to make your customers fall in love with your content again, take a look at your email subject line. Using the wrong words could be triggering those annoying SPAM filters. 

There are two ways your emails get flagged as spam. The first is through the internet service provider (ISP) that hosts a prospect or customer's email server. If an ISP finds an email untrustworthy, they will most likely flag it as spam. The second way your emails get spammed is by the recipients themselves. One or two "spammy" mishaps won't ruin you, but if an ISP receives several spam reports from your email, you may end up being blocked altogether. 

One of the best things you can do to prevent being spammed is to avoid using any of these "spammy" words in your email subject line. Keep this list handy, because you'll use it often. And don't forget to apply the "Email Subject Line Do's And Don'ts" at the bottom of this article. Good luck!
