Subject lines are a great place to start testing when it comes to email marketing. They play the largest role in open rates and one subject line can outperform another by astounding figures.

Ex: MarketingExperiments.com and CopyBlogger put on a subject line test for the Optimization Summit in Denver. The winning variation had a click-through rate 125% higher than the worst performing variation. Amazing!

Don’t be afraid to test multiple subject lines as you never know what may win. What’s the saying? Always be testing.

Our Recommendation:

Write down a few subject lines you want to test and start pitting them against one another. Make sure you run them long enough and evenly. Also check out this great post from MailChimp for tips and best practices on writing subject lines and this fun tool.
