400 spam-trigger keywords that you should ban from your email content in 2021

Spam filters are using keyword detection to spot junk emails and make sure your inbox stays clean. This is why you should choose carefully the words used in the subject and body of your emails. Here's is the ultimate list of spam-trigger keyword that you should ban from your email content in 2021!

Spam filters are algorithms, designed and trained to detect spam and to refuse them the entrance in your inbox.

They are pretty good at it. Maybe too good…

So good that they may block some relevant emails, just because you used a word they consider as "bad" in the subject or in the body of your message for instance.

No matter if you warmed up perfectly your inbox, and set up your SPF, DKIM, and DMARC. They will just kick you out of the inbox if you use spam trigger words.

The easiest way to avoid spam filters is to choose carefully the words used in the subject and body of your emails.

These "negative keywords" are mainly manipulative, shady, cheap, or needy ones. The kind of words or groups of words that spammers are using in most of their emails.

Just for you, we gathered 400 negative keywords that can make your emails flagged as spammy in 2021.

Our list of spam keywords you should ban from your emails.

Disclaimer: This list is non-exhaustive.  Having one word of the list in your email doesn't mean that it will land in spam for sure.
