The 100 Worst Spam Words and Phrases to Avoid in Your Subject Line

Delivery Updated on August 5, 2022

Stop me if you’ve heard this one before… Monday, Tuesday, any day really, you log in to your email inbox and you have 42 new messages. “You have won the Ukrainian Lottery!” “Make Millions NOW!!” “Please help [insert someone from I have no idea where who would like to give you money from their trust fund so you can hang on to it for some reason].” And that most classic of spam emails: Viagra.

What do you do now?

I think most of you will mark these as spam or delete them to focus on your real emails. Let’s turn that around. Are your valued subscribers any different? Sometimes it might even be your own email newsletter or important promotional info that gets junked.

How Do You Avoid This?

The most important elements of any email are the “From” and “Subject Line” details.

These two key ingredients will convince your subscriber to either open your emails or not. Ignore the importance of these elements, and your intended recipient might never even see the email. It will more likely bounce out of the inbox or be swallowed by a spam filter. Below I present the 100 keywords to avoid when writing a subject line. Some will simply be filtered out by the email client (depending on the restrictiveness of its parameters) while others will be marked as spam by the user.

100 Words and Phrases that Scream SPAM

Words or phrases that reference a promo, discount, or sale.
Words or phrases that reference emotion, trust, and vague promises.
Words or phrases that reference a sense of urgency, the pressure to act immediately, sometimes related to getting rich money or work-at-home schemes.
Words or phrases that reference financial gain, sometimes related to the following industries, credit card, loan, and or mortgage services.
Words or phrases that reference the pharmaceutical industry.

Add to this list of words and phrases everything else that has something to do with pharmacy and pornography and words spelled in ALL CAPS, e.x.t.r.a. punctuation, dis o r g an iz_ed text, followed by $$$ or 100%, 50%, etc.

After reading this exhaustive list, I’m sure you’re wondering what words can be used….

Let’s just keep it simple. Use a subject line that you would open yourself, something that is not too flashy but raises some interest for the subscriber. Follow this with a familiar “From” name that your subscriber can relate to (which should be no different from your regular sending address since your customer/subscriber has opted-in to your contact list).
