Dear Mailjet team,
I want to use the inbox preview feature as described in this article:
https://www.mailjet.com/de/blog/produkt/inbox-preview/
But when I go into the email designer and click on preview, I can only see one mobile and one desktop preview but I want to check it for various email clients. How can I activate it? Does an admin have to do something? I am in a sandbox account.
Best wishes,
Sebastian
