Hello There!
I'm havig a problem that is making me lose a lot of time
I create a test responsive template template using mailbuild.rookiewebstudio, I even test it sending it by Mailchimp , is totally responsive and the layout change between mobile and desktop.

THIS IS THE PROBLEM
I uploaded this template on Acymail, the process goes well without any error.
When I send a test email, the email that I receive displays perfectly on desktop, but on mobile is not responsive anymore.

I open it through the same devices that I opened it when I test the template before upload it on Acymail

Anyone that can help?
