When writing email marketing outreach messages to promote your upcoming webinar, follow these best practices to increase registrations:

  • Conduct A/B tests on subject lines: Validate your assumptions and optimize your subject lines by running A/B tests. Test different elements, such as recipient name inclusion, urgency, emojis, punctuation choices (hyphens vs. colons), webinar title vs. descriptive copy, and the presence of the date. Remember to analyze the results of your A/B tests to refine your subject line strategies and maximize the impact of your webinar email marketing.
