Email marketing is an especially powerful tool for businesses. New email marketing tactics and strategies allow even the smallest companies to create campaigns that are professional and effective. There are, however, some things that will land your email in the spam folder faster than you can say “delete.” These factors include email spam trigger words.

Editor’s note: Looking for the right email marketing solution for your business? Fill out the below questionnaire to have our vendor partners contact you about your needs.

What causes email to be flagged as spam?

Some reasons why emails wind up in the spam folder include the use of improperly misleading subject titles and marketing emails that are sent to recipients who haven’t opted in. Low-engagement approaches to email marketing and campaigns that target inactive addresses can also end up in the spam filter. So can the numerous possible violations of the CAN-SPAM Act. Email spam trigger words are also a fast path right to the spam folder.

Using spam words in your email content is one of the most common email marketing mistakes to avoid, as it will prevent your content from being delivered to a wide portion of your target audience. Instead, use thoughtful and well-crafted content that engages your audience to ensure higher open rates and conversions.

Key TakeawayKey takeaway
If your emails are going to spam, the reason might be a combination of your word choices, audience targeting, email list maintenance and other factors.

What are email spam trigger words?

Craig Klein, CEO of SalesNexus, an online CRM and email marketing firm, compiled an excellent list of more than 250 words that, when included in your company’s emails, can result in them being classified as spam by your recipient’s spam filter.

“This is not the definitive or an entire list of words that activate spam filters,” said Klein in his blog post on SalesNexus’s website. “It does give you a general idea of what to avoid in your email marketing. Obviously, anything salacious or that has sexual or pornographic words will get you blocked and could get you in trouble with your ISP (internet service provider). In addition, don’t use $, !, * or any symbols, particularly in the subject line. Things like mon$y or nak*d just don’t make it. The folks that create the filters are way too sophisticated for that type of silliness.”

Klein’s list, compiled by the marketing services director of SalesNexus, Steven Greene, includes no-brainers like “online pharmacy” and “money — no refund!” But other terms on the list are phrases you might use every day. They include “click to remove,” “click below” and “marketing solutions.”

How to avoid spam filters

If you can’t avoid using one or two of the above phrases in an email, you can still bypass the spam filter. To do so, take the following steps:

  • Provide full context in your emails.
  • Personalize your emails — e.g., address recipients by name.
  • Contact only recipients who have opted in to your emails.
  • Include a way to opt out of future emails.
  • Design emails using clean code and standard fonts.

Spam filters are much more sophisticated than in the past, so using one or two spam trigger words won’t automatically send your email to the spam folder. Follow the above steps and make sure messages are carefully worded to avoid sensational language and extreme punctuation. That way, your emails will be sure to reach their target.

A direct, personalized and carefully constructed subject line is one of the best ways to guarantee that emails bypass the spam filter and are opened by the recipient.

Avoid spam trigger words for email marketing success

If your emails keep being sent straight to the spam folder, bookmark this list and use it to make sure you haven’t included any spam trigger words. This list is not comprehensive, so make sure your emails are carefully worded, specific, engaging and sent to recipients who have opted in. 

In addition to avoiding spam trigger words, use best practices in creating an email list, avoid common email marketing mistakes, use the right customer segmentation, and choose one of the best email marketing software solutions, such as the one described in our iContact review. These best practices help guarantee your emails will be successful. If you follow them, your days of hitting the spam folder might soon be in the past.
