OneSignal Email Delivery and Statistics

As a reminder, our email reports offer the following vital information you'll want to reference in the process of evaluating the efficacy of your email campaigns.

Delivery

We offer visibility into high-level delivery stats such as how the message was created, when it started sending, how long it took to fully send and any throttling limits in place.

Engagement Statistics

In addition to delivery stats, we provide fundamental engagement statistics including open and click-through rates.

Open Rate: The rate of unique recipients who opened or viewed the contents of your email. Open rates may fall if you send emails at too high of a frequency, for instance.

Click-Through Rate (CTR): The rate of unique recipients to who an email was delivered to and who clicked any link within the email itself. CTRs can indicate how well your content is engaging your audience and how motivated they are to take the next action in the buyer's journey.

How to Create an A/B Test With OneSignal

First, select your editing experience — you can choose between our painless drag & drop editor, our custom HTML editor, or one of our pre-built templates.

Next, add your variants. You may add up to 10 variations of your email, as well as save your current test as its own custom template for future experimenting.

Finally, it's time to set your A/B audience settings. This is where you will set the percentage of your audience to randomly receive one of your variants. Variants are sent out randomly to the audience percentage you choose, but they are also sent equally.

So, if you set your test audience to 25%, 12.5% will receive variant A and the other 12.5% will receive variant B. If you keep your test audience at 25% with three variants, 8.3% would receive variant A, 8.3% would receive variant B, and 8.3% would receive variant C. And so on!

After some time has passed, you'll be ready to select a winner based on the engagement data you've collected.
