Actionable Tips To Write Better Event Email Subject Lines

Subject lines are vital for creating positive first impressions since people decide to open your email based on what they read in the inbox.

However, it’s hard to find powerful words that keep your target demographic engaged without sounding too spammy.

Luckily, we’ve uncovered the secrets to writing catchy email subject lines and want to share them with you.

Here goes!

Keep it concise

Adding every tiny detail in your subject line is tempting — but it’s best to include those details in the main body of your email.

Keeping subject lines concise will ensure high email open rates, especially since most recipients open their emails on mobile devices. It needs to hook them right away in a few words.

So, to ensure your readers open your email, here are some tips for keeping subject lines easy to read:

• Avoid complicated terms or jargon.
• Keep subject lines between 6 and 10 words.
• Use simple and clear language.

Create a sense of urgency

To prod email recipients into action, your subject line should create a sense of urgency.

There are many ways to do so, one of them being to include a deadline in your subject line. This way, you can increase conversions as people feel pressured to join your event before tickets and seats run out.

Another method is to offer an immediate solution to the audience’s problem.

By doing so, you’ll persuade people to take action now — especially if it’s a rare opportunity — and make them open the email to register.

Also, you can leverage the power of emojis to visualize urgency and catch attention. This is a simple and effective trick that actually works!

Channel the power of FOMO

We’ve all heard of FOMO — a popular but effective marketing strategy that uses people’s fear of missing out to get them to act.

You can employ this tool when writing your email event subject lines, and you can do so by:

• Counting down the number of days left before the event.
• Mentioning how many people have already signed up to attend.
• Highlighting the limited number of seats left.
• Naming some of the event’s biggest guests.

A/B test your emails to improve your metrics

One of the best and fastest ways to determine whether your email subject lines will perform is to conduct an A/B test.

It involves testing two event subject lines by sending them to a different segment of your email list — and seeing which your audience likes better.

Fortunately, Moosend is an expert when it comes to A/B testing.

Since Moosend is an all-in-one email marketing solution, you can easily see which email content, campaign, and subject line performs better by following simple steps.

Make it personal when possible

Your subject lines should feel like an invitation from a friend rather than a bland or generic invite that might give recipients the impression you don’t care whether they attend the event.

It’s easy to make subject lines feel personal; you can include the subscriber’s name in the subject line or even use “you” to get their attention; this way, you connect with your potential attendees more organically.

Sending personalized emails is Moosend’s forte.

With their solution, users can easily send customized emails without much effort, and it can help them significantly improve the efficiency of their email marketing campaigns.

Avoid spam words

In your event subject lines, using spam words — keywords that email service providers identify as red flags — is a big no-no.

Doing this, you risk triggering spam filters that might reroute your email to the recipient’s junk box and hinder your engagement efforts.

Generally, this happens because people associate spam words with money or scams — let’s look at some examples:

• Urgent
• Act now
• Order expires
• Last chance
• $$$
• Risk-free
• Luxury
• No obligation
• Dear friend
• Email harvest
• We hate spam

Check out this article to see a definitive list of email spam words.

Now, let’s examine five examples of amazing event invitation emails that compel people to register.

5 Examples Of Great Event Invitation Email Subject Lines

You’ve made it to the practical part of this article.

As promised, we’ll share with you five good email subject line examples that capture your reader’s attention and drive conversions.

1. Miro

Subject line: Live Sessions for the Lifelong Learners

This email caters to the target audience’s love for knowledge, which is clear straight from the subject line.

People hungry to grow professionally will want to use Miro’s resources to optimize their processes. However, the email contains more than an invitation to live sessions.

Aside from promoting upcoming webinars, Miro entices readers to attend their helpful online courses, which are especially useful for those preferring to learn by themselves.

Users can also see links to guides and resources if they’d rather read than watch a video.

It’s a catchy and comprehensive example that pleases subscribers and keeps them engaged with relevant content.

2. Calendly

Subject line: Last chance: Learn how marketers use Calendly to accelerate pipeline

Let’s look at a more standard email example that urges people to RSVP as soon as possible.

This email serves as a reminder that the event will start soon. Sometimes, people might forget to register or need a bit of persuasion to get them to act in time.

Calendly nudges subscribers by creating a sense of urgency and triggering FOMO straight from the subject line, using “Last chance.”

These types of emails also have the necessary information about the event, such as what they’ll learn or the date and time, to remind readers of what they might miss out on.

3. Salesforce

Subject line: Day one is now streaming on Salesforce+

People usually see these kinds of emails on the day of the event. In this case, the subscriber has already registered for the event and is eagerly waiting for it to start.

So, this is a great email to send your attendees on the first day of the online event to maintain engagement.

Aside from offering a link to the stream, Salesforce also included a schedule. With this information, attendees could see what was on the agenda and join the sessions they were most interested in on time.

4. Dovetail

Subject line: We’ll be seeing you Stateside 🇺🇸

Dovetail’s example targets returning attendees familiar with their events who might be interested in other opportunities.

In this email, Dovetail invites recipients to attend an in-person conference.

It encourages them to register for the event by offering extra incentives such as drinks, food, and fun alongside people with similar interests.

Plus, the target audience will feel more comfortable with the idea because Dovetail hosts the event in a town nearby, so they will only need to travel a little to reach the conference.

Listing the guest speakers may also help persuade them further.

5. Slack

Subject line: Sessions are ready — we just need you

Slack gets personal with recipients from the start, using “We just need you” to show how much they value the readers’ presence at this event.

To persuade them, Slack promises valuable insights and actionable tips that attendees should take advantage of to grow in the future.

Moreover, they use FOMO to encourage readers to attend because this is a once-in-a-lifetime chance to unlock their organization’s potential with Slack.

While it’s a simple email design, it offers all the information the recipient needs to decide whether to attend, such as a glimpse of the agenda and the time and date of the event.
