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?”
Common subject line mistakes and how to avoid them
Avoid these common pitfalls:
- Writing long, hard-to-follow subject lines
- Using punctuation, which can bump up your character count
- Using all capital letters
- Including misleading information to get your reader to open the email
Fortunately, these common mistakes are easy to avoid. Focus on catchy, accurate subject lines with low character counts. Keep the caps lock off unless you need to emphasize certain words.

How to write a preheader that complements your subject line
The preheader is the summary text that appears below the subject line in your inbox. When written thoughtfully, the preheader should complement your subject line and make your email invitation more enticing. Follow these tips when composing preheaders:
- Keep preheaders short, so they don’t truncate. Aim for 50 to 100 characters for your preheader text.
- Carry the same tone from your subject line into your email. Whether you’re writing more formally about an upcoming event or using conversational language, apply a consistent tone throughout.
- Provide additional information to entice the reader to open the email.
- Use actionable language to encourage readers to open the email and learn more about your event.
- Evaluate your subject line and preheader combinations to determine which ones perform best.

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:
- [Name], see you at [Event Name]?
- [Name], we’re saving you a seat
- Join fellow [description of attendees] at [Event Name]
- Don’t miss out on [Event Name]
- Don’t forget: X days left to register for [Event Name]
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.
- Special, early bird offer for our fans!
- Exclusive ticket price just for [Name]
- Hi [Name], it’s here: [Event Name + Year]
- We’re back — and you should be too!
- [Name,] let’s meet again at [Event Name]
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.
- Last chance to see [Speaker/Performer] live at [Event Name]!
- [Event Name] is almost sold out, [Name]. Get your tickets now!
- You’re about to miss [Event Name]! Get your tickets before they sell out
- Last call for tickets!

- Don’t forget: your tickets to [Event Name] are waiting!
Subject lines for speaker and performer announcements
