Hey @Tiago Campos  Given the nature of this query and that we’ll likely need some further details here, I’m going to pass this over to the team as a Conversation to take further action on this issue for you!

Hi Bernice where is the answer to this? 

I am wondering about this too. 

Thank you. 

Hey @Philip Chen! Thanks for reaching out here

At the moment, this option is not available to customize this preview text within our UI. After the Subject line, the text that appears in the email preview is whatever your first line of text is. You're not able to adjust/custom-fit that. In relation to the image question here, if your email only has an image with text within it, there is no way to make that text the subject line.

This is a great idea from Tiago has been flagged with our Product team as a Feature Request 

I’ve opened a Conversation for you with the team so you can share any additional details or context to your workflow that you think might be helpful - please feel free to include them!  We take input from our customers with great consideration when creating new features and refining our current solutions
