Tips for writing effective subject lines

Event invitation subject lines must be well-written to draw your reader in and make them want to learn more.

First, make sure your subject line is concise. You want to get your message across in five to seven words or about 40 characters. Remember, many recipients will be viewing the email on mobile devices, so you want the complete subject line to be visible on any device. Your subject lines should give just enough detail to intrigue your readers and push them to open up the email for more information.

Next, tap into readers’ emotions when crafting an invitation subject line. You can do this in several ways. Create FOMO (fear of missing out) when publicizing your event. Or, add a sense of urgency if few tickets are remaining. Offer a teaser about your event in the subject line to create mystery and entice recipients to read on.

Personalizing your subject lines can also increase engagement. Research shows that emails with personalized subject lines are 26% more likely to be opened. One simple way to personalize the email is by including your recipient’s name in the subject line. If you have an established relationship with your email target, go for more in-depth personalization. For example, reference their previous attendance at your events with the subject line “See you again soon?”

Subject lines for your first event invitation email

When it comes to your first invite to an event, you need to create urgency and build excitement in the subject line to get the reader to open the email. So whether it’s an amazing concert, a networking and industry meetup, or a food experience unlike any other, make it irresistible for recipients with a great hook. Another tactic is personalization — using a recipient’s name or city can encourage them to keep reading.

Subject lines that encourage RSVPs

You want to know who’s coming to your event, so lock in those RSVPs via email. These emails are a practical way to follow up with potential attendees who haven’t RSVP’d yet, and an RSVP subject line — when done right — can hook them. Your email will remind them that your event is coming up and encourage them to register or secure their tickets. When crafted properly, these RSVP email subject lines can help boost attendance:

Subject lines for inviting returning attendees

Your returning attendees want to feel special and appreciated, especially if they’ve been attending your events for a long time. Highlight discounted prices or unique perks for returning fans to show them you value them.

Another useful technique is segmentation, or dividing your email list into relevant target groups (demographics or geography, for example). This lets you create subject lines that resonate with different audiences. Check out these “you’re invited” email subject lines.

Subject lines for a last-minute reminder email

Sometimes people wait until the last minute to sign up for an event — or they forget they ever signed up. When sending out last-minute reminders, create a sense of urgency and FOMO to get them to open the email.

Subject lines for speaker and performer announcements

There’s nothing more exciting than announcing your hard-won speaker or performer lineup. That’s the moment when you can lean in to attract potential event-goers to your conference or festival and build up enthusiasm with your audience. Introduce your speakers and performers with a catchy subject line that draws your potential attendees in.

Subject lines for virtual events

If you’re promoting a virtual event, send emails to share key details and get the word out. Virtual event-goers will need to know how the event will be delivered (livestreamed? recorded?) and what platform they’ll use to access it. When developing your virtual event subject lines and emails, brainstorm how to entice potential attendees. For example, highlight how you’ll make it interactive and engaging even in a virtual space.
