Webinar Email Subject Lines That Work in 2024 (+ Templates)

by Maxim Poulsen, updated on Apr 26, 2024

With inboxes overflowing, your webinar's first challenge is catching attention. Even the most engaging webinar can fail if the email goes unopened. That's why your webinar email subject lines need to be clear and create curiosity.

But how do you write irresistible subject lines that grab attention and drive sign-ups?

In this article, you'll find proven strategies for writing email subject lines. We've also shared templates that will get your webinar emails opened.

Importance of Webinar Email Subject Lines

Think about your inbox. It's packed, right?

But if you have an irresistible subject line your webinar email sequence will stand out. 

ConstantContact found that the average open rate for emails hovers around 39.7%. That's your benchmark to beat. But here's the kicker: if your subject line doesn't hit the mark, your email might be ignored. 

A strong subject line does more than tempt someone to click open. You're promising them what's inside is relevant and worth their time.

A bad webinar email subject line could also end up getting your message flagged as spam. And having a high spam rate will negatively affect ALL emails being sent out from your company.

As of February 2024, Google requires bulk senders to keep spam rates below 0.3%. Imagine you’re sending a webinar email invitation to 1000 contacts. Only 3 people need to mark that email as spam for you to hit that 0.3% spam rate. If that happens a few times you could tank your entire email marketing program. 

Best Practices for Writing Webinar Email Subject Lines

Crafting a good webinar email subject line requires a mix of creativity, clarity, and urgency. Here’s a straightforward guide on nailing it every time.

Show Value and Solve Pain Points

Your audience is looking for solutions, not just information. When you're brainstorming your subject line, ask yourself: "What's in it for them?". Make sure your subject line clearly states the value of your webinar and how it addresses specific challenges or pain points.

For example, "Transform Your Marketing in One Hour: Strategies That Work." This subject line grabs attention by promising quick, practical results within a short timeframe. It is ideal for busy professionals looking for actionable marketing strategies.

Be Concise and Clear

The best subject lines are short and sweet, making it immediately clear what the email is about. You want your attendees to know at a glance why your webinar is worth their time.

A direct call to action (CTA) like "Register Now" or "Reserve Your Spot" adds an extra nudge. Remember, clarity is key, so keep your subject line focused and to the point.

Tips for being concise:

  • Stick to 50-60 characters to make sure your subject line isn’t cut off in most email clients.
  • Use active verbs to make your CTA compelling.

Create a Sense of Urgency

Nothing spurs action like a little urgency.

Use countdown language like "Webinar Starts in 2 Days!". Or mention limited availability - "Only 10 Seats Remaining" - to encourage immediate registration. If there’s an early bird special or a time-limited offer, highlight it. This approach taps into the fear of missing out (FOMO) and can boost your webinar sign-up rates.

Personalize Webinar Email Subject Lines

Adding a personal touch to your email subject lines can dramatically increase open rates. Personalization goes beyond just inserting the recipient's name. 

Consider customizing the subject line with their company, job title, or industry. This shows the recipient that the webinar content is tailored to their needs and interests, making them more likely to engage.

Personalization techniques:

  • "John, Boost Your Sales Strategy with Our Latest Insights"
  • "How Revops Leaders in Tech Can Solve Attribution"

CRM integrations like Contrast's HubSpot integration can help with personalization. These integrations allow for deeper insights into your leads. This data can help you craft even more targeted and relevant subject lines. 

Imagine sending a subject line that not only includes the recipient's name but also references the last webinar they attended. That’s the kind of personalization that gets clicks.

Maximizing your Results through Great Webinar Emails

To get the best out of your webinars, the emails you send out play a huge part. Here’s how to craft engaging webinar emails that reach and resonate with your audience.

A/B Test your Webinar Email Subject Lines

A/B testing your webinar email subject lines is a great way to see what resonates with your audience. Most email platforms like HubSpot let you A/B test two different versions of your email. 

You can use that platform’s reporting to see which subject line got a higher open rate. But you can go one step further. With Contrast’s UTM tracking, you can also measure which webinar email subject line drives more registrations. That’s ultimately what matters.  

Use the Right Language to Talk to your Audience

When it comes to webinar email subject lines, clarity is king. Your subject lines should be crisp, clear, and concise.

Be mindful of your email preheader. That's the short preview text that follows the subject line in the inbox. It acts like a wingman to your subject line and can help convince people to open your email. 

What about emojis in webinar email subject lines? Sprinkle them like salt. It can enhance the flavor, but don’t overdo it.

Repurpose Content for Post-Webinar Emails

Repurposing webinar content transforms the best moments into different types of content. This isn't about filling a content calendar with fluff. It's about using existing assets in a smart way. It can generate new engagement, remind attendees of the value, and encourage people to sign up for your next webinar.

Email Timing

Your industry, your audience, time zones, and the day of the week can all influence the best timing for your webinar emails.

According to HubSpot, the highest open rates are typically on Tuesdays, Wednesdays, and Thursday mornings. 

Our own study of 100,000 webinar registrants found that 41% of registrations happened on Tuesdays and Thursdays. So those are the best days to send out webinar invitation emails.

The countdown to your webinar is also important. In general, you should send an initial invitation about a month in advance, followed by reminders as the event approaches. A last-minute email reminder can reconnect those who might have forgotten.
