450+ Spam Trigger Words to Avoid in Your Copy

Last Updated June 27, 2024

Choosing the words used in your emails is always a delicate task.

You want to present your products in the right way, entice the reader to engage with your message and take your desired action, and yet stay on the good side to avoid words that trigger spam filters.

But sometimes, while pushing for compellingness and ensuring that the email is conveying the purpose of your message, the use of certain words pushes email service providers’ spam filters to place your emails in the spam folder.

In this article, we share the latest list of spam trigger words to avoid you need to be aware of to keep your emails safe from landing in the spam folder and ensure you always get delivered.

What are spam trigger words?

Email spam trigger words are words and phrases included in your email that email providers’s email filtering algorithms see as red flags and consider malicious for the recipient of the email and therefore block the email being delivered.

These are mostly words that are used in email subject lines as well as email bodies in an attempt to get an action or reaction from the reader.

They trigger spam filters that consider them spam words because they find them suspicious, misleading, or too good to be true and send the email to the spam folder.

Spam trigger words can tip your beautifully-written email to the wrong side of the inbox of your recipients, who will, therefore, not receive your communication — even if you don’t mean to use those words and phrases.

The main reason email marketing specialists need to learn about email spam words to avoid is that constantly having your email marketing campaigns sent to spam folders hurts email deliverability.

Down the road, constantly having your emails flagged by spam filters damages your sender reputation, and spam filters will always send your email campaigns to the spam folders anytime they receive emails from your domain.

Before we reveal the list of email spam trigger words to you, it is important to put things in context to show you the types of words that get flagged as spam emails.

What types of words do spam filters flag?

There are a gazillion words and phrases that get flagged by email spam filters. It can seem hard to always know which ones, but there is a pattern.

Spam filters only catch suspicious words and phrases associated with the following:

Scams: setting up dishonest schemes or frauds and using words and phrases like ‘free money’, ‘instant weight loss’, ’billions’.
Manipulation: creating unnecessary urgency with words like ‘Urgent’, and ’Don’t delete’. This also includes using words that are too specific to marketing and the idea of sales.
Gimmicks: adding tricky words to elicit emotions or drive action.
Promises: constantly making promises across the email.
Free gifts: include too many gifts and promising free stuff in your email subject line or content.
Neediness: sounding desperate and needy with words like ‘Help’, and ’Distress’
Sleaziness: using inappropriate, out-of-context, or sex language with words like hot babes, or adult.
Shadiness: ethically or legally questionable behavior.
Being too cheap: making unrealistic discounts with words and phrases including ‘Free’, 100% off, Full Discount.

450+ spam trigger words per category and business industry

There is a list of words and phrases that are considered suspicious or potentially spammy by email providers.

These will be detected, trigger some sort of red flag, and the spam filters in your recipient’s inbox will likely place your email in junk status to protect the recipient.

What if you cannot do without these words?

You will be bound to use some spam trigger words. Sometimes, it only makes sense to use them to formulate your message or make your offer compelling to your audience.

In some contexts even, they can operate as power words to inspire your recipients to take action.

So, you’re probably asking yourself whether you will get your email flagged as spam anytime you include any of these words in your emails or subject lines.

From our experience, the real problem is the frequency with which you use them and how many of them you include in your email that triggers the spam filter.

The reason we believe this is that spam filter algorithms work based on a scoring system rather than simply seeing the word and instantly flagging the entire email as spam.

They consider your sentences and the number of potentially spammy words or phrases it contains — both your email subject lines and copy.

Based on the data gathered, they score your email an overall spam score, which determines whether your email lands in the spam folder or the inbox.

Of course, the higher your spam score the lower your chances of getting your email delivered in the inbox.

So back to your question. Yes, you can use the words and phrases that make sense to you. It’s only a matter of density.

Spam filters are becoming more and more sophisticated and allow for nuance. It is a matter of context and sensible use. So, you make sure you include these words or any kind of power words in your email copy sparingly.

Key Takeaways

The risks linked to these words are constantly evolving, so stay tuned, we update this list regularly. Finally, note that although using these words is risky, you can continue to use them, but sparingly.
If you want to maximize your chances, refrain as much as possible from placing them in the subject line of your message. This requires a little effort, a good dose and a lot of creativity, but the results of your campaign will be all the better.
Also, always ensure that you follow the CAN-SPAM Act laws and include an unsubscribe link in your email campaign. CAN-SPAM Act laws govern commercial emails — emails sent by a company attempting to sell or promote its products. Always aligning with them will help with your email deliverability and avoid fines owing to poor email marketing.
