A\u002FB tests send different versions of the same email to two groups to see which performs better. Most email marketing systems automate the process, meaning all you have to do is set up each version and hit ‘send.’\u003C\u002Fp>\u003Cp class=\"wp-block-paragraph\">You can A\u002FB test almost any aspect of an email, including subject lines, copy and design elements. A typical A\u002FB test for subject lines might look something like this:\u003C\u002Fp>\u003Cp class=\"wp-block-paragraph\">\u003Cstrong>Create your variants\u003C\u002Fstrong> – Write two subject lines. They should be different enough that you can draw a meaningful conclusion from the results.

Before you design an elaborate experiment, look back at past campaigns and try to glean insights from the data you already have.\u003C\u002Fp>\u003Cp class=\"wp-block-paragraph\">If certain campaigns always perform better than others, there’s no need to run an A\u002FB test to confirm what the data is already showing you.\u003C\u002Fp>\u003Cp class=\"wp-block-paragraph\">For everything else, the next step is to decide what to test first.\u003C\u002Fp>\u003Ch2 class=\"wp-block-heading\" id=\"toc-2--form-a-hypothesis\">Form a hypothesis\u003C\u002Fh2>\u003Cp class=\"wp-block-paragraph\">Don’t jump in head first and start testing email components at random. Instead, take a critical look at every part of your email campaigns and make an educated guess about what changes will make the biggest difference. After all, you know your audience and campaigns better than anyone.\u003C\u002Fp>\u003Cp class=\"wp-block-paragraph\">In some cases, analytics metrics can help diagnose problem areas. If people are opening emails but not clicking, focus on the contents of the email itself.

If you test multiple changes at once and see a difference in performance, you won’t know which change caused it.\u003C\u002Fp>\u003Cp class=\"wp-block-paragraph\">Some email marketing tools do offer multivariate testing, which allows you to test multiple variables at once. This can make sense to optimize a single campaign by identifying the best combination. However, because they don’t isolate the variables, multivariate tests make it hard to pinpoint useful take-aways for the future.\u003C\u002Fp>\u003Cfigure class=\"wp-block-image aligncenter\">\u003Cimg loading=\"lazy\" decoding=\"async\" width=\"600\" height=\"327\" src=\"\u002Fcdn\u002Fen\u002F2020\u002F11\u002F19190430\u002Femail-campaign-optimization-data.jpg\" alt=\"Illustration of marketers standing around a screen with graphs and data on it, discussing email campaign optimization.\" class=\"wp-image-50907\" srcset=\"\u002Fcdn\u002Fen\u002F2020\u002F11\u002F19190430\u002Femail-campaign-optimization-data.jpg 600w, \u002Fcdn\u002Fen\u002F2020\u002F11\u002F19190430\u002Femail-campaign-optimization-data-450x245.jpg 450w\" \u002F>\u003C\u002Ffigure>\u003Ch4 class=\"wp-block-heading\">Have a big enough sample\u003C\u002Fh4>\u003Cp class=\"wp-block-paragraph\">For your findings to be statistically significant, you need a big enough sample size.\u003C\u002Fp>\u003Cp class=\"wp-block-paragraph\">Mailchimp \u003Ca href=\"https:\u002F\u002Fmailchimp.com\u002Fhelp\u002Fcreate-an-ab-testing-campaign\u002F\" target=\"_blank\" rel=\"noopener\">recommends\u003C\u002Fa> sending each test version to at least 5,000 contacts for the best results.

Before you get started, figure out what your metric for success will be. Usually, click-through rate is the best choice.\u003C\u002Fp>\u003Ch3 class=\"wp-block-heading\">How to test each email component\u003C\u002Fh3>\u003Ch4 class=\"wp-block-heading\">Type of content\u003C\u002Fh4>\u003Cp class=\"wp-block-paragraph\">Are you sending emails that customers want to receive? After all, fine-tuning subject lines won’t get you very far if customers are fundamentally disinterested in the content of the email.\u003C\u002Fp>\u003Cp class=\"wp-block-paragraph\">This is one that’s hard to A\u002FB test. Instead, look for trends in your past campaigns. Maybe your product tutorials get all the clicks, while newsletters languish unread. That’s a valuable insight.\u003C\u002Fp>\u003Cp class=\"wp-block-paragraph\">Of course, not every customer likes the same type of content. That’s where email segmentation comes in. By grouping your mailing list into segments, you can send different types of campaigns to different people.

You’ll definitely want to keep those in rotation. The next step is to optimize your new product messaging. Do customers care more that your product saves them money, or that it lets them unleash their creativity? An A\u002FB test in which you emphasize cost savings in one version email, and creative inspiration in the other, should answer that question.\u003C\u002Fp>\u003Ch4 class=\"wp-block-heading\">Cadence\u003C\u002Fh4>\u003Cp class=\"wp-block-paragraph\">Cadence is also hard to A\u002FB test, but it’s still worth trying to optimize. One approach is to simply increase or decrease the frequency of your marketing emails, and watch what happens to your clicks and unsubscribes.\u003C\u002Fp>\u003Cp class=\"wp-block-paragraph\">Or you could manually split your list, and send each group a version of the same campaign with a different cadence. This approach is a bit more work, but also more accurate.\u003C\u002Fp>\u003Cp class=\"wp-block-paragraph\">Whichever approach you choose, don’t forget to compare total click-through rates for the campaign.
