Can someone tell me how to change the banner size (where the company logos are)? There seems to be a lot of white area around the logos and I would like this to be smaller.
Thanks in advance!
I think this is a question that is unique to your particular design and setup. You'd be best engaging a creative agency or an IT resource to help you with this one.
Is this in email or in Landing Page?
This is done in your templates, in both case, and, as Nicholas pointed out, it has to be done by a designer.
As suggested by Greg and Nicholas, thought to connect and discuss your specific requirement for design/development of email, landing page or newsletter. Below is the link for few of responsive assets built by us:
