You can A/B test your Digesto email using the following method:

1) Prepare A and B Versions of Your Marketo Email
Create an email for each variation. We recommend you change only one element at a time, for example:
- Subject line
- Template colors
- Email title/headline
- Etc.
​
​2) Split Your Email Send
From your Digesto Send Email Smart Campaign, use the random function to split the distribution of your two emails.
​

3) View Results
Once your email is distributed, you can view your results using Email Insights or from an Email performance report.
​
​4) Declare Winner / Rinse & Repeat
For more details on A/B testing and statistical significance, check out this post from the Marketo Community.

​
​Known Limitations:
Neither the Email Program A/B Test nor the Champion/Challenger method available in Marketo is compatible with Digesto Emails. Therefore, the method outlined here will not perform actions such as:
- Automated declaration of the champion
- Email alerts to declare a champion in the champion/challenger A/B test
- The post layout (portion populated by Digesto and sourced from your feed) cannot be split/tested using this method.
