How it works

There is a time difference between sending the email and viewing the images.The images are downloaded at the moment the recipient opens the email. The email only contains a link to the images which are located on a server.   

    

Normal setting, without 8Seconds Optimizer
An email is made of html code referring to the sender's server. The images in the email are located on that server. The recipients download the images from the server when opening the email.


Optimization setting, with 8Seconds Optimizer
When the email campaign is optimized, the html code is slightly modified. The code now refers to the 8Seconds server. This server redirects immediately to the different images which are still located on the sender’s server. In this way, 8Seconds shows different images to different recipients and measures which image (or combination of images) is the most successful in terms of conversion. As soon as the optimal email is found, 8Seconds automatically shows this best version to all next recipients that open the email.
