Don't forget to think of how your subject line will look on different size screens.

Here's a preview of how it looks on desktop and mobile screens:

Why does the subject line matter so much?

In a world saturated with emails coming from all kinds of brands, you need to make sure you’re cutting through the clutter, and the email subject line is your opportunity to do just that.

Captivating subject lines are vital when you’re looking to maximise open rates and see better outcomes overall. Because when your subscribers are quickly scanning over the umpteen emails in their inbox, yours needs to stick out and make them want to find out more.

But how exactly can you create the ideal subject line when building your digital marketing campaigns?

What goes into writing a high-converting email subject line?

Personalise it

When you write your email subject lines, consider bringing in some emotional value to your message by doing something to personalise it. This might include using their name at the start or targeting segments from particular locations that are relevant to your campaign.

Make it short

You don’t want to overshare and give everything away in the email subject line; write with a word mixture mixture that intrigues will garner more clicks.

Also, keep word count between 4 to 6 words, and the character count at 40 characters maximum to avoid word cutoff in the email subject line.

Use numbers

Studies suggest that using a number, especially odd, at the start of the email subject line can lead to increased email open rates.

Take the right approach

Within the subject line as well as the email copy, the words you choose to use (power words, positive words, negative words, etc.) are going to dramatically affect campaign results. Boost open rates and achieve optimum results with a word mixture that aligns with the type of subject line you’re aiming for:

Belonging
Anticipation
FOMO
Curiosity
Hope

Promote offers and discounts

We all love not paying full price, buy-one-get-one-free promotions and other similar discounts and offers. A subject line based on a current promotion you’re running is sure to garner a much higher open rate.

FAQs

Why are email subject lines so important in email marketing?

Even if you’ve created a campaign that includes the best email content that’s ever existed, if your target audience doesn’t click through to it they’ll never see it.

As such, it makes sense that the element which has the opportunity to gauge their interest and make them click through – the email subject line) is without a doubt the most important of all.

What makes the perfect email subject line?

First and foremost is the word count. If your word count is above 6, you’re risking that it gets cut off by the recipients’ email clients. Data also suggest that if the word count is below 4, this can also have a negative effect on open rates. Keep the word count between 4-6 words for optimal performance.

Next is the character count. Data shows that a character count between 21-40 sees better open rates, so make sure to stick to that.

Your word choice is also essential. Using spam words is a big no-no of course, but in addition to avoiding spam words you also want a succinct word mixture and balance creativity with the point you want to get across. This also includes the preheader text. Be sure to test subject lines before sending with the best of all email subject line testers found at the top of this page!
