I'm trying (failing miserably) to setup mandrill/mailchimp to work with rails 4 and devise.
I'm having loads of trouble using dynamic fields, but now, i can't even insert my logo without mail chimp overriding it to put a black square background behind it.
All I have done is import the image, then when I try to resize it in mailchimp, it imposes a black square background.
Does anyone know how to block this background from being imposed?
