The Ultimate List of 394 Email Spam Trigger Words to Avoid in 2021

After spending hours creating an email marketing campaign, the last thing you want to do is get blocked by your recipients’ spam filters. Luckily, by avoiding common email spam trigger words, you can successfully prevent your emails from getting routed to spam folders.

Let’s take a look at what spam trigger words are, what gets emails sent to spam, and which spam words you should avoid when creating your email campaigns.

Spam filters can be triggered for a variety of reasons, causing your email to skip recipients’ inboxes and land straight in their spam inbox. One of the easiest ways to avoid spam filters is by carefully choosing the words you use in your email’s subject line.

Trigger words are known to cause problems and increase the chances of your email getting caught in a spam trap. By avoiding these words in your email subject lines, you can dramatically increase your chances of getting beyond the filters.

Spam trigger words alone aren’t enough to send your email to spam. For instance, if you are offering a 3-for-1 discount sale, you can still advertise that in your emails and not get sent to spam. It’s important to understand all the factors that come into play when emails get identified as spam.

What causes emails to go to spam?

Email providers look for a number of factors when deciding whether to automatically send your emails to spam. If you’ve made it on an email blacklist, that means you’ve repeatedly sent emails to recipients who haven’t signed up for your email list.

Your emails can get sent to spam if you:

• Don’t include an unsubscribe button in your email
• Send poorly-designed emails with broken or glitchy code
• Address your recipient by “my friend” or “dear” (or not by their name)
• Buy email lists online and mass-send messages to email addresses that don’t exist (resulting in a high bounce rate)
• Use all-caps text and extreme punctuation (!!!!! or ?????)
• Include strangely formatted fonts (???? ????)
• Provide links to fraudulent websites

Email providers only want to deliver emails from high-reputation senders. To be a high-reputation sender, do the following:

• Include an unsubscribe button
• Design your emails with clean code using a tool such as Marketing Hub
• Personalize your emails with the recipient’s first name
• Only email those who’ve subscribed to your email list (if you don’t have any, you should learn to naturally increase your email list subscribers)
• Keep your email deliverability high
• Keep the text free of odd formatting and extraneous punctuation
• Only link out to reputable websites

If you meet these criteria, you can get away with using “classic” email spam words in your subject line and your email. The text surrounding the spam phrase also matters, as does your history as an email sender. If email providers don’t have a reason to mistrust you, they simply won’t.

Email Spam Words to Avoid

When writing your email subject lines, you want to avoid:

• Over-sensationalizing
• Over-promising
• Using strange formatting to “stand out” in the recipient’s inbox

Next time you sit down to write an email subject line, consult the exhaustive list below. In fact, you might want to bookmark this list so you can refer back to it every time you craft an email subject line.
