Image Optimization FAQs

IMPORTANT: Image Optimizer has been retired as of June 12, 2024. We recommend utilizing A/B split testing in your ESP or other available solutions for similar results.

What is Image Optimization?

The Litmus Personalize Image Optimizer allows you to conduct image optimization live in your email. The most converting image after the initial quota of opens will automatically be displayed for the remainder of the campaign opens. The highest converting image for the campaign at that point in time will display for the rest of the campaign.

How does it work?

Simply upload the images you wish to test against one another, and select an open quota, for example, 1000 opens. The first 1000 opens will randomly see one of the images being tested using the image optimizer. After the first 1000 opens, the image with the highest conversion rate compared to the other images will automatically display to the remainder of the recipients opening the email.

How do I decide on the Open Quota?

Select the number of random opens to be used for optimization before the winning image is displayed. We recommend selecting a quota that is between 10-15% of your expected number of opens.
