Unlock the Power of A/B Testing for Newsletters

Email newsletters are the cornerstone of audience engagement—but let’s be honest, sending out a newsletter without testing is like throwing spaghetti at the wall to see what sticks. 

It’s a strategy… but not a good one.

This is where A/B testing comes in. 

It’s how the pros turn “meh” emails into must-reads, and it’s a game-changer for anyone looking to grow their audience or monetize effectively.

With beehiiv, A/B testing becomes not only simple but incredibly powerful. 

You’ll be making data-driven decisions that optimize every element of your newsletter—from the subject line to the send time—and see results you can measure.

What Is A/B Testing, and Why Should You Care?

In case you’re new to the game, A/B testing (a.k.a. split testing) compares two (or more) versions of an email to see which one performs better. Whether it’s open rates, click-through rates, or conversions, testing gives you the cold, hard data you need to make informed decisions.

The result? No more guessing, no more assumptions—just actionable insights that take your newsletters from good to great.

Why A/B Testing Is a Must for Newsletter Growth

Let’s break it down:

Open Rates: A/B testing lets you identify the subject lines and preview text that get your audience to actually open your emails.

Click-Through Rates: By testing different content layouts, tones, and CTAs, you can pinpoint what makes readers click.

Send Times: Not all send times are created equal. A/B testing reveals when your audience is most active.

Engagement and Retention: Test formats, lengths, or even image use to understand what keeps subscribers engaged—and coming back for more.

At the end of the day, A/B testing ensures you’re delivering value, not cluttering inboxes.

What Can You Test in Your beehiiv Newsletter?

beehiiv makes A/B testing intuitive and robust, letting you experiment with just about every aspect of your newsletter. Here’s where you can start:

Your subject line is your first (and sometimes only) chance to grab attention. With beehiiv, you can test different tones, emojis, word counts, or even personalization.

Example A/B Test:

Version A: “How Creators Are Growing Their Audiences by 500% 🚀”

Version B: “Want to Double Your Audience? Here’s How…”

Pro Tip: Keep the preview text in mind—it’s the supporting cast to your subject line’s main act.

How to Run A/B Tests Like a Pro Using beehiiv

Here’s how beehiiv makes A/B testing seamless:

Choose What to Test

Focus on one element at a time—subject lines, CTAs, send times, etc.—so you know exactly what’s driving the change.

Set Up Variations

Create two (or more) versions of your email directly within beehiiv’s interface. Define your audience split, and you’re good to go.

Analyze the Data

Once the test runs, beehiiv’s detailed analytics will show you the winning version. Look at key metrics like open rates, CTR, and overall engagement.

Iterate and Improve

A/B testing is never a one-and-done process. The more you test, the better you’ll understand your audience—and the more optimized your emails will become.

Best Practices for A/B Testing Your Newsletters

If you want to make the most out of your tests, keep these tips in mind:

• One Variable at a Time: Avoid changing multiple elements in a single test. 

• Timing Matters: Let your test run for enough time to gather meaningful data.

• Sample Size is Key: Make sure your audience split is large enough to get reliable results.

• Log Everything: Keep a record of your tests and insights for future reference.
