Help edit embedded app view in email

[Gianlucapozza]

Hello, 

I'm having trouble editing an embedded app view that I want to send with a bot (or on command) when a new record is added to a table. In the screenshot below I would love to:

• Smaller header 
• Bigger pictures
• Clickable position (like a G-Maps lat/long field)

I can't find how editing pictures in email bodies works. Another solutions could be a template. Once I've set up this app view my goal is to make the receiver clik a button and change a counter that signals me that the activity was completed since I dont want to make another app or filtered views just to do that action.

Thanks in advance
