How to Write Webinar Invitation Emails: Templates, Examples & Tips

Estimated reading time: 4 minutes

Webinars have become one of the most effective tools for nurturing leads, educating audiences, and showcasing expertise. But even the most valuable webinar won’t perform well if people don’t open your message or fail to register. That’s where a strong webinar invitation email strategy makes all the difference. 

Let’s make your next webinar email invite your highest-converting one yet.

How to Write a High-Converting Webinar Invitation Email

1. Start with a clear promise.

People sign up when they know exactly what they’ll get. Instead of vague teasers, highlight a result:
“Learn 5 ways to improve your ABM strategy.”

2. Use engaging webinar invite subject lines.

Short, curiosity-driven, and outcome-focused subject lines outperform generic ones.
Examples:

• “Join us live: How to grow your list without ads.”
  
• “You’re invited: A webinar that will change your onboarding workflow.”
  
• “Can’t-miss insights from top SaaS teams (live webinar)”

3. Highlight the speaker.

If your speaker is credible, show it. Include industry roles, achievements, or notable past talks.

4. Keep the structure simple.

A high-performing webinar invitation usually includes:

• A strong headline.
• Day, time, and platform.
• Bullets or short sentences describing value.
• A clear CTA button.

5. Add a sense of urgency.

Webinars are time-sensitive. Use phrasing like: “Only 300 seats available” or “Registration closes soon.”

6. Optimize for mobile.

Most people read emails on their phone. Keep paragraphs short and CTA buttons visible.

7. Test your deliverability.

Before sending, run your webinar email through GlockApps Spam Test. It helps ensure your webinar invitation email actually reaches the Primary inbox. Testing beforehand will help you troubleshoot any issues with deliverability.

Tips for Crafting Webinar Invite Subject Lines

Great webinar invite subject lines are:

• Short (5–8 words)
• Clear about the topic
• Benefit-driven
• Sometimes curiosity-based

Examples:

• “Your seat is waiting, register now.”
• “Live training: Convert more leads effortlessly.”
• “Want better engagement? Join our webinar.”

How Many Webinar Invitation Emails Should You Send?

Most brands send a sequence of 3–5 webinar emails:

1. Announcement
2. Main webinar invitation
3. Reminder 48 hours before
4. Reminder 1 hour before
5. Final “We’re starting now!” message

This sequence significantly increases attendance without feeling spammy.
