The way you promote your event matters, especially when it comes to emails. 78% of event creators say email marketing is their most effective marketing tactic. Even more important, the ones who track the source of their sales say 45% of event ticket sales can be attributed to email. That’s enough reason to take this channel seriously.

But before you get too far along in your email campaign, you need a good email subject line. Good subject lines will make your open rates soar, while bad ones will get you kicked out of even your newest subscriber’s inbox. In this article, we’ll show how to write attention-grabbing email subject lines for events and give you examples of subject lines that work.

Why a good event email subject line is so important

Think of your email subject line as a pass to an invite-only exclusive event—if you don’t have a pass, you don’t get in. At least four out of every ten subscribers open emails because of the subject line. Even more people—almost seven out of ten email recipients—will mark your email as spam for the same reason. 

So, if you want people to read your event emails, then you need to master writing email subject lines. The bright side is that when you do it right, you can shoot up your open and click-through rates. 

How to write effective email subject lines for events

Here are a few tips to help you write catchy email subject lines that get readers interested in your event.

Tip #1: Keep it short and sweet

You might be tempted to include as many details as you can about the event in your subject line. However, shorter works better—especially on mobile devices where the email subject can get cut off. Studies have shown that subject lines with 6 to 10 words have the highest email open rates. 

Tip #2: Leverage FOMO

When it comes to writing event email subject lines, FOMO (or the fear of missing out) is a powerful tool in your arsenal. 56% of all social media users experience FOMO, while for millennials, the number is nearly 69%. Highlight the number of days left, mention how many people have already signed up to attend, or name drop your biggest guest(s) and speakers. 

Tip #3: Make it personal

A personal invitation from a friend feels better than a generic invite. The same holds true for event emails. Targeted emails with personalized subject lines can increase email open rates by up to 50%. This approach can be as simple as including your subscriber’s name in the subject line, or even just using the word “you.” 

Tip #4: Include numbers and emojis

When it comes to email subject lines, numbers work. According to a study by Moz, headlines with numbers generate 15% more clicks. Find creative ways to include important data about your event in your email subject line, such as the number of tickets bought or days left to purchase them.

Emojis also make a difference when used correctly. One study found that businesses that use emojis in their email subject lines have over 50% higher open rates than those that don’t. The trick is to use a relevant emoji, and to use them sparingly—one is often all it takes.
