Let’s talk about a nightmare every influencer, creator, and digital marketer dreads—your beautifully crafted email campaign vanishing into the spam abyss before it even sees the light of day.
You spent time perfecting that email, crafting the perfect subject line, only to have it land where emails go to die—the spam folder. And let’s be real, no one checks their spam folder unless they’re desperately searching for a lost password reset email.
So, what’s the problem? More often than not, your subject line is the culprit. Spam filters are like overprotective bouncers—if they see something even remotely suspicious, your email isn’t getting through.
Let’s break down 20 spam-triggering words that can tank your email deliverability and keep your message from reaching your subscribers’ inboxes.
Avoid These Words to Stay Out of the Spam Folder
- Free
The OG spam trigger. Everyone loves free stuff, but spam filters see this word and assume your email is either too good to be true or selling something shady. - Guarantee
Sounds reassuring, right? Wrong. Email algorithms love to flag this word because it often accompanies scammy sales pitches. - No Risk
Oh, the irony. Claiming “no risk” makes email providers suspicious that there’s a huge risk involved. - This is Not Spam
Telling someone “this is not spam” is like walking into a store and shouting, “I swear I’m not stealing!” If you have to say it, people (and spam filters) assume it’s a lie. - Act Now
Urgency is great for marketing, but spam filters see pushy language like this and assume you’re just another desperate sales pitch. - Limited Time Offer
Similar to “act now,” this phrase raises red flags because it’s been overused in aggressive sales emails. - Winner
Even if you’re actually announcing a giveaway winner, this word can trigger spam filters because it’s been abused by fake lottery scams for years. - Amazing
It may be amazing, but spam filters don’t think so. Overuse of this word makes an email sound hyped-up and untrustworthy. - Cancel at Any Time
Instead of sounding reassuring, this phrase raises suspicion that there’s a catch. It’s the fine print no one wants to read. - Cash
The quickest way to make your email look like a get-rich-quick scheme. Avoid it unless you want to sound like a spammy finance guru. - Earn Extra Cash
Just like “cash,” this phrase sets off alarms that your email may contain sketchy side hustle promises. - Congratulations
Even if you’re actually celebrating a win, this one is so overused by scams that it often gets flagged. - Click Here
Sounds innocent, but it’s a favorite phrase of phishing scams. Instead, make your links natural within the sentence. - Buy Now
Straight-up sales language like this is a no-go if you want your email to land in the inbox. - Order Now
Same issue as “buy now.” Too aggressive, too pushy, too spammy. - Special Promotion
Overused to the point where spam filters see it as a giant red flag. Instead, be more specific about what you’re offering. - Increase Your
This phrase often signals a vague, overpromised claim. Anything that suggests a “guaranteed improvement” (like “increase your traffic”) can trigger spam filters. - Traffic
If you’re in digital marketing, this one’s tricky. Spam filters often flag emails offering traffic growth, assuming they’re scammy bot services. - Online Biz
Feels informal and unprofessional. Spam filters associate it with sketchy work-from-home schemes. - Multi-level Marketing (MLM)
Anything hinting at MLM is an instant spam filter magnet. If your email includes these words, your open rates are in trouble.
How to Write Subject Lines That Get Into the Inbox
Now that we know what not to do, here’s how to craft subject lines that boost deliverability and increase email open rates:
- Be Clear and Specific – Instead of saying “Act Now for a Special Promotion!” try “Get 20% Off – Only Available This Week.”
- Make It Personal – Emails with personalized subject lines perform better and avoid spam filters. “Sarah, Here’s Your Exclusive Invite” feels direct and real.
- Use Curiosity, Not Clickbait – Instead of “You Won’t Believe This!” try something like “The Email You’ve Been Waiting For.”
- Avoid Over-the-Top Hype – Words like “amazing” and “unbelievable” scream spam to both filters and subscribers. Keep it genuine.
- Test Your Subject Lines – Most email platforms let you A/B test subject lines so you can see what works best.
The Bottom Line: Play It Smart with Subject Lines
The best email marketing strategies for influencers focus on genuine connections, not gimmicks. Spam filters are smart, but your audience is even smarter. They can tell when an email is truly valuable versus when it’s just trying to sell them something.
By avoiding spam-trigger words, crafting authentic subject lines, and keeping your email content engaging and valuable, you’ll land in more inboxes, get more opens, and build deeper relationships with your subscribers.
So next time you’re crafting a subject line, ditch the spammy buzzwords, keep it real, and watch your email performance skyrocket.
