Did you know that 14.7% of emails get caught by spam filters? (EmailToolTester). This might seem like a small number but if you consider that only 21.5% of emails get opened, this shifts to be a really big deal.
If your subject headlines are filled with email spam trigger words, your business is bound to suffer. You can prevent this by carefully picking the words in your email’s subject line.
Typically, the trigger words can be grouped into these 6 broad categories:
Manipulative: creating unnecessary urgency or pressure.
Needy: sounding desperate or exaggerated claims.
Sleazy: being too pushy.
Cheap: no pre-qualifications, everybody wins.
Far-fetched: statements that are too good to be true.
Shady: ethically or legally questionable behavior.
At Ortto, we’ve compiled a list of 250 spam trigger words that you should avoid like the plague. It’s important to note that although a single incidence of these words may not be enough to trigger the spam filter gods, you should still avoid them wherever possible.
There is nothing wrong with urging your reader to take action, but spam filters often penalize emails with subject lines that create unnecessary urgency and pressure.
If everything you send is “urgent,” then nothing is, at least in your recipient’s mind.
On the other hand, if there’s enough value in what you have to offer to your readers, urgency will happen organically. In the meantime, avoid using the following email spam trigger words:

Your email subscribers are looking for immediate value when they see your subject line; they want to know exactly what they’ll get when they click on your email. If you’re truly offering something of value, there’s no need for you to be desperate or make exaggerated claims. Just like the following email spam trigger words:

Sleazy words and phrases
When spam filters spot subject lines with words that are sexual, they automatically spam them. There’s no doubt about that. If you’re operating a dating site, your business could suffer because of this. The best approach is to be discreet and leave suggestive words out of your subject lines.
Here are a few examples:
Cutie
Hot babes
Hottie
Kinky
Mature
Meet girls
Meet singles
Meet women
Sex
Sexy babes
Steamy
It’s human nature to long for unique things, something that no one else has. So if your email subject lines keep giving off an “everybody wins” vibe, the value of your product diminishes in the eyes of your customers. On top of that, your email is likely to end up in spam.
By avoiding these email spam trigger words, your value proposition will increase in the eyes of your customers:
