There are certain words you don’t, can’t, shouldn’t, and mustn’t use within your email subject line if you want to pique people’s interest while avoiding spam blockers.
It’s one thing if you’re sending a personal email to a prospect or customer — but if you’re sending mass emails, you’re not going to get very far if 90% of your messages get blocked before they ever reach their intended recipient.
There are so many spam trigger words, someone could write a nice thick book about them. Emails that promise untold riches and exclusive rewards reserved only for a special elite few. Remember that prince from Nigeria?
Let’s get into our list of words to avoid in email subject lines, so you can stay miles away from the spam folder.

1. Anything to do with money.

- Get paid
- Big bucks
- Credit or Debit
Email marketing may be one of the most successful marketing channels out there, but that doesn’t mean email service providers want you clogging up their servers with it. You may be doing marketing when you email clients, but that doesn’t mean you need to remind them you’re doing it.

- Content marketing
- Digital marketing
- Account-based marketing (ABM)

Instead, provide actual content in your email that your readers will be interested in engaging with.

- Get it now
- Once in a lifetime
- For new customers only
- Offer expires
- Deal ending soon
Leave the hard-sell advertising copy to Madison Avenue. Words like INCREDIBLE, and AMAZING smack of desperation and make you look fly-by-night.

- The best
- You will not believe your eyes!
5. Days of the week
This is especially true because of the flood of emails for things like Cyber Monday, Black Friday, Giving Tuesday, and so on. There are significant drops in open rates of emails with day names in the subject line.
- Last Day
- Friday before [holiday]

Make Email Marketing Work for You
To start, try to avoid sending generic messages to everyone in your database. It can be difficult, especially with limited resources and pressing deadlines. But segmenting your audience, personalizing your messaging, and testing frequency can lead to improved open and click-through rates.
Hopefully, once you start building an email relationship with your prospects, your messages will make it to their inbox. But when you’re starting out with those initial conversations, don’t risk anything. Avoid the “naughty words” and keep on your prospects’ — and their email servers’ — good side.
