Sales Email Subject Lines That Get Opened

sales email subject line

As a sales rep, email is one of your most powerful tools. It allows you to reach a large group of potential buyers at the same time, casting a wide net and increasing your chances of getting a hook.

But whether or not your sales emailing outreach works all comes down to one thing: the subject line.

Your subject line has only 3 seconds to capture the attention of the reader. Otherwise, sionara. Three seconds is a very small window of time, which means your subject line has to be the most exciting mini-elevator pitch you’ve got. 

Three seconds is the magic number, according to the US Consumer Device Preference Report from Movable Ink.

Knowing that the average person takes so little time to decide if your email gets opened or deleted, you have to put a lot of thought into which words you choose. 

A good subject line should do one of three things. It should either:

  • elicit an emotional response,
  • create a sense of urgency,
  • Or evoke fear, uncertainty, or doubt. 

But, it’s important not to be too salesy or deceitful, so click-baity subject lines are a no-no. A good sales email subject line should tell the prospect exactly what to expect before opening the email and get to the point quickly. 

That being said, we’ve put together some of the best sales email subject line tactics available today.

Use your sales email subject line to spark FOMO

Nobody likes missing out on something, which is why this tip involves igniting the Fear Of Missing Out. Make your prospect feel like there’s some urgency behind your email and they won’t be able to resist opening it.

Last chance? Is it really the last chance? What event was this again? Did I want to go to it? I can’t remember, I should probably open the email. 

5 Spots left! Don’t miss out

Use word play in your sales subject lines

Quick call on Friday

When using words like quick, short, or small, you are implying that you won’t take up too much of the person’s time – which is the main reason why they hesitate to open in the first place!

Re: call on Tuesday

This one is a bit sneaky but it works every time. Use the words “Re:” before your subject line to trick the prospect into thinking there is already an on-going conversation between the two of you. They wouldn’t delete an email they’ve already replied to, right?
