13 Examples of Professional Email Subject Lines

13 professional email subject line archetypes for selling business products

If you could, you’d hire a professional email subject line writer. You would, because you depend on your email list to sell magazine subscriptions or ads to advertisers, so smashing together 50-100 characters on the fly every day is a stinky approach to accomplishing those goals.

And let’s not forget that email subject lines typically double as blog titles, Tweets and the clickable links in Facebook posts. If you’re catering to a business audience like we are, they also double as Linkedin headlines.

Speaking to professionals through email is more arduous than trying to sweet-talk consumers. Consumers subscribe to emails because they want to, whereas professionals subscribe to B2B email newsletters because they need to — likely for their job. Not to mention, selling a $10 product to a consumer is easier than selling a $995 ticket to a conference, where approval from management is typically required.


That’s why writing great professional email subject lines is so important.

This is true even if you only write a few good ones and repeat them over and over again. It seems like repeating the same phrases would tire people out, right? You’d think so, but only recently was I finally able to beat our “make money online” headlines, and only by a pinch.

See, we always test our own professional email subject lines. In the past, the term “make money online” has performed well for us. No matter how many times we’ve tested, nine times out of 10, the “make millions” or “make money online” subject line wins. Here are some reigning champions, who have won against the others we’ve thrown up against them. Our first place winner, by the way, the often-repeated, tried and true version, wins frequently against our second place subject line, but not all the time.

  • How to Make Millions with a Content-Driven Website – first place
  • Wanted: Independent, Ambitious Publishers to Make Millions of Dollars – second place

The challenge: You might find it to be a gimmicky headline, but using the phrase “making millions” or “make millions” in our subject line wins all the time. So, what we’re saying is… if you’re sick of seeing it, blame yourselves for clicking! Just kidding. Instead, we challenge you to come up with something better that we can test!

    Hi Rick, we haven’t gotten bagged for it yet, it really depends on your email sender score (reputation). We even get away with using the word “free” once in a while, although I’d recommend checking in on yours before trying it out! Your ESP might have this information, but I believe you can also find out here: https://www.senderscore.org/


    I read the the word millions, million were spam alert words.

    Please advise.
