Ready to Start A/B Testing? Here are 50 Ideas to Get You Started

The first step in setting up an A/B test is deciding what to test—and the possibilities are virtually endless. If you can change it, you can test it! But that doesn’t mean you should spend months testing every aspect of your email campaign. Instead, focus on the things that are most important, or those likely to have the greatest impact.

Keep in mind, different tests will impact different parts of the conversion process. So you may want to start by evaluating the strengths and weaknesses of your current campaign performance. If your open rate is low, testing different subject lines is a great idea. On the other hand, if you’re looking to increase your click-through rate, you’d want to test elements like the offer or call to action (CTA).

At a high level, the elements you might want to consider include:

  • Subject line (alter the length, wording, etc.)
  • Personalization (e.g., “Mr. Smith” vs. “Kyle”)
  • Headline (vary the size, color, style, or wording)
  • Content (longer vs. shorter, text vs. visuals)
  • Layout (single column vs. two column, or different placement for different elements)
  • Imagery
  • Offer (Example: “Save 20%” vs. “Get free shipping”)
  • Call to action (Example: “Buy Now!” vs. “See Plans & Pricing”)
