How to write email subject lines for more opens

Email marketing has the potential to bring in the highest ROI for your business when done correctly. Working on growing your email marketing list is one thing, but then making sure your list is active and engaging with your emails are another.So how can you write subject lines to increase your open rates? Read on and find out.

Create mystery and intrigue

Humans are curious creatures, so feed that curiosity with your subject lines. Tease your audience about the content that they have the potential to receive. Tap into what resonates with them and lure them into finding out more.

An example subject line:
“Growing your email list is as easy as the clicking your mouse”

Reveal your content

Now, this may sound counterintuitive following the mystery and curiosity tip above, however, by revealing your content you are setting an expectation for your audience. Allowing your subscribers to know what they are about to open, can help convince them of the value of your send. It will also act as an indicator for you to understand what type of content resonates with your audience and what does not.

Having irrelevant subject lines can also be annoying; subscribers may decide to unsubscribe, or worse, mark you as spam!

An example subject line:
“Find out how to increase your email open rates!”

Create a sense of urgency

This type of subject line is great for sales, special offers, or a limited offer. Creating a sense of urgency in your subject line forces your subscribers into the mindset of taking action. It puts a clock on an offer; they do not want to feel like they are missing out on an opportunity.

An example subject line:
“Hurry! This 15% Off Deal Ends Tomorrow!”

Keep it short and sweet

Our inboxes are filled with emails, and today’s average person is time poor. Keeping your subject line to 5 – 7 words not only saves time in reading but also succinctly conveys what your message.

An example subject line:
“Grow Your Email Database With 5 Easy Steps”

Use numbers

Numbers in your subject line can help increase curiosity in the mind of your subscriber, but also make your subject line easy to read at a glance. The use of a number also breaks up the text in an inbox making it stand out amongst other emails.

An example subject line:
“3 Ways To Improve Your Email Marketing”

Ask a question

Again, curiosity wins. Asking a question in your subject line makes the reader wonder about the answer, and to fulfill that curiosity they will open the email to see what that answer is. The questions do not have to be complex. It can be simple, as long as it is relevant to your subscribers.

An example subject line:
“Are You Using These Top Email Marketing Methods?”

Use Action words

Action words can be more enticing to a reader as it allows them to imagine themselves completing an activity. The action word also builds an allure through curiosity and the excitement of being a part of something. Adding action words into your subject line will lead to more clicks to opens than a generic subject line.

An example subject line:
“Contribute To Our Next Newsletter!”

Personalise your content

The more relevant an email, the more likely it is to resonate with our reader, the more likely it is to be opened. When we say personalisation, we don’t simply mean the first name. Personalisation can be created through the local area, past purchase behaviour, website behaviour, gender, age, household status etc. Anything that specifically relates to your reader.

Segmenting your list will help to better personalise and your email subject lines, or if you could use dynamic subject lines by pulling fields of data.

An example subject line:
“Jane, Check Out These School Holiday Activities In Glebe”

Test, test, test

It’s important to be constantly testing your subject lines. Be this through A/B testing, using a different subject line for non-openers or simply using a different method with each send.
