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.
Not only does spam email marketing betray the trust of customers, but it can also contain malware and viruses. Ultimately, you’ll want to avoid sending spam emails because your customers won’t read them.
Let’s 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: It’s best to give recipients the option to opt-out of emails. Provide an unsubscribe link.
Send poorly-designed emails with broken or glitchy code: Poorly-designed emails create an unpleasant reading experience. Readers will regret opening your note in the first place if the format is hard to read and the design doesn’t render properly.
Address your recipient by “my friend” or “dear” (or not by their name): To get the best results, add a personal touch in the subject line or message to increase your open rate and provide a better customer experience.
Buy email lists online and mass-send messages to email addresses that don’t exist (resulting in a high bounce rate): Not only do the recipients not know you, you could quickly ruin your IP reputation and put your email deliverability at risk. If you do business in Europe, buying email lists could also be a violation of the General Data Protection Regulation (GDPR) which requires explicit permission from your contacts to send them emails.
Use all-caps text and extreme punctuation (!!!!! or ?????): Many spam detecting software will automatically register emails formatted in all-caps as spam. It also doesn’t help to look like you’re shouting at the reader.
Include strangely formatted fonts (𝖑𝖎𝖐𝖊 𝖙𝖍𝖎𝖘): Similar to using all-caps, weird fonts are more difficult to read and are likely to trigger spam detecting software.
Provide links to fraudulent websites: This should be obvious, but never link to fraudulent websites in your emails. It’s harmful to your contacts and undermines your credibility.
Now that you know what not to do, let’s go over some best practices to ensure your emails steer clear of spam folders.
How to Become a High-Reputation Email Sender
Email providers only want to deliver emails from high-reputation senders. To be a high-reputation sender, do the following:
Include an unsubscribe button: Communication is a two-way street. Ensure your contacts can opt-out if they choose by placing an unsubscribe link in your email.
Design your emails with clean code using a tool such as Marketing Hub: Take the guesswork out of designing emails. With these tools, your emails will open glitch-free every time.
Personalize your emails with the recipient’s first name: 71% of consumers expect email personalization. Address them by name and watch as your open rates improve.
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: Doing the tasks above will improve deliverability but you should also make sure you are compliant with the legal guidelines in your region. Most marketing software is compliant with web laws but if you’re handling email in-house, you’ll want to double check your emails are compliant.
Keep the text free of odd formatting and extraneous punctuation: Clean and clear copy ensures your note is easy to read and dodges spam detectors.
Only link out to reputable websites: Only link to reputable sites you trust. After all, your reputation is on the line. Don’t lose credibility by sending your contacts to shady 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

Use Spam Trigger Words Sparingly and Within Context
So long as you use email marketing best practices and use spam trigger words within context, you can bypass spam filters. Spam filters have become much more sophisticated in recent years. Using one or two phrases won’t hurt you, but make sure to only email customers who want to hear from you and to always personalize your emails. Doing so will optimize the results of your campaign and keep you out of spam folders.
