Thank you for reaching out to us. I can understand how having the ability to change the format of the button could make it easier for you to design your email the way you want it to look. At this time, there are limited customizable options for our button feature. Although this is something that has limited customization, I'd be more than happy to submit your feedback to the correct team for review. Also, there are possibly some websites that could offer an option to customize your own button. With that said, you can create a button and also create an image out of that button and insert this image (of a button) into the email and link it to wherever you need it to go.
In regards to having a background image within the body of the email, this is currently something we do not have available as a feature in our newer editor. We are tracking feedback in regards to this feature and I can add your account to the track to be notified if a feature like this is ever implemented. Also, the newer editor is fully mobile responsive. Any templates being created in this editor will be adjusted when receiving them in mobile to make it easier to read.
I apologize for any inconvenience this may have caused. Your feedback is always appreciated as we are always working for ways to improve your/our customers experience with the system.
If you happen to have any additional questions, feel free to reach back out to us. In the meantime, I hope you have a wonderful rest of your day!
