What are Spam Trigger Words?

Spam trigger words or stop words are certain phrases or terms that, when present in the email content or subject line, can trigger spam filters.

A spam filter is a program that detects virus-infected, unwanted, and unsolicited emails and prevents them from landing in a user’s inbox. This filter also has specific criteria as a basis for its judgments.

When an email is flagged as spam by the spam filter, it can be deleted after a period of time or instantly. Major email service providers, including Gmail or Hotmail, have built-in spam filters to protect their users.

Therefore, it is important to avoid using spam trigger words to ensure your emails are delivered to your target audience’s inbox.

Basically, avoid being:

  • Cheap – Avoid spammy words like “100% off,” “Free,” and “Full Discount.”
  • Needy – Don’t scare off the beautiful and handsome folks on your email list. Avoid sounding desperate with spam words like “Save big,” “Distress,” and “Help.”
  • Sleazy and Salesy – Forget sleazy and salesy marketing tactics that some email marketers are guilty of. These words include “adult” and “hot babes.”
  • Far-fetched – Stay away from words like “billions,” free money,” and “lose weight.”
  • Manipulative – Asking for your recipient’s credit card information is surely spam. So, avoid manipulative words. Moreover, avoid creating a false urgency with spammy words like “Expires today,” “Final Call,” or “Urgent.”

Getting to know your prospects first before emailing them is a great practice to boost email deliverability. So, try to determine when and how they prefer to receive emails from you.

Knowing your recipient can also segment your list, allowing you to respond better to their pain points.

In fact, your recipients may unsubscribe from your newsletters or mark them as spam emails if they feel overwhelmed by the communications.

If you hate spam, then so does your audience. Thus, it’s best to start slow and focus on the quality of your email over frequency.

3. Authenticate Your Email

This is another important practice to ensure your deliverability. Authenticating your email also proves that your emails are not forged.

Some effective authentication methods include Sender’s Policy Frameworks (SPF), Domain Keys Identified Mail (DKIM), and Domain-Based Message Authentication, Reporting, and Conformance (DMARC).
