Email has evolved a lot in the last decade, becoming a highly regulated and controlled technology, with new protocols and mechanisms between the sender and the recipient created each year.
How words trigger the spam filters
You don’t need to know the technical aspects and insider secrets when emailing your friends or colleagues, but it’s definitely a must if you run email campaigns (especially those with multiple email sequences).
The answer to why some or all of your email messages end up in the spam folder is actually pretty simple – spam words. Spam detection mechanisms use smart algorithms that track everything about you as a sender and your message as an email content, including SMTP server information, domain information, links and pictures in your emails, your recipients and more.
The email content itself can land you in trouble even if your sender reputation is pristine. It’s not a secret that some of the words trigger email spam filters. These are called spam trigger words, and here we compiled an updated list of them for 2024 just for you. Explore the spam words list below.

Downloaded and shared! Awesome list, guys.
A good chunk of our emails still lands in spam, though.
Could it be the attachments?
Dian, attachments can have a negative impact on email deliverability, you are right. Read our guide to check if these are attachments that make your emails be delivered to the Spam folder.
many thanks for such an amazing list! it is really great but the spam rate is still very high. do you have any guesses why it happens so and how I can reduce it?
thanks in advance.
Cale, a high spam rate could happen out of two reasons: either the ESPs filter your emails as spam or your recipients label your emails spam. Check out our guide to reduce the spam rate.
Great guide, Paul, thank you!
