Overview

A/B tests allow you to create multiple versions of an email template in a sequence step to determine which message resonates more with prospects. With more than one email per sequence step, you can tweak messaging and refine communication over time to book more meetings and close more deals.

Did you know? The more A/B tests a sequence has, the better for your sender reputation and deliverability score. Varied messages tend to indicate authenticity instead of spam. So while A/B tests can help you fine-tune your messaging to resonate with each persona, they can also improve your sender score.

Use an A/B Test in a Sequence

It's in the Plan

Some Apollo plans include A/B tests. To access A/B tests, upgrade your plan. If you have questions about upgrading, reach out to the Apollo sales team.

First, create a sequence or use an existing sequence. Then, add an A/B test:

  1. Launch Apollo and click Sequences. Select a sequence.

Sequences

  1. Add an automatic or manual email step, then click Add A/B Test on the step you want to test.
Watch Your Step

You can only A/B test email steps. It isn't possible to A/B test other sequence steps or an entire sequence flow.

  1. Apollo creates a new email with no subject or body. Click the email.

An example new blank email is highlighted

  1. Edit the email template or use the AI assistant to generate content. When finished, click Save.

To B or Not To B

To effectively identify what is and isn't working at speed and scale, begin by A/B testing wildly different email templates. Then iterate on the templates of the best-performing messages by A/B testing more specific variables like individual subject lines or body text.

  1. After editing your message, toggle the emails on.

  1. Apollo evenly distributes each message variant in the A/B test to different contacts in the sequence step.

Repeat this process for additional emails and sequence steps. Then, observe the delivery data Apollo collects for each email. When you've collected enough data, you can determine the best-performing messages, and deactivate underperforming content.

 
How Much Data is Enough?

Rather than A/B test an arbitrary number like 100 or 200 delivered messages, optimize by testing an amount that is statistically significant. Online calculators can help determine statistical significance. Then, only determine an A/B test winner if you have a 90% or greater confidence interval. Learn more in lesson 5 of the Build a World Class Outbound Program Master Class.

In general, higher performing content will have higher delivery and interested rates, and lower spam blocked and opt out rates.
