Email Subject Line Optimization: New Resources and Tools Using ML


Boosting Email Open Rate with Better Subject Lines

Your email subject line is a very significant factor for email performance. One subject-line optimization tool claims a 49.5% conversion lift (on average), from better subject lines. Another tool claims a 60% increase in open rates. We’ve also seen 96% and even 99% prediction accuracy.

Something important is going on here. . .

It’s easy to see why you would want to know beforehand which subject lines will perform better, without waiting to do an A/B test on your actual emails. Now, machine learning has emerged as the way to do that.

In this webinar, we’ll present a curated list of tools and resources (out of more than 20 that we reviewed), plus you’ll get an insider look at the Top 5 tools out there today, including strengths and weaknesses of each.

In this session, you will learn:

  • What is email subject-line optimization and how does it actually work?
  • What kind of impact can you expect from subject line optimization?
  • What are the top five tools that do this?
  • Best practices for testing
