Mail chimp with Devise and Rails

Question

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?

Answer 1

This came from mail chimp support: Also, it's important to mention that because of the lack of a background color for transparent image, a black background is automatically added when the image is edited. Two workarounds would be to resize the image outside of the account in an any outside image editor, or add a white or other colored background, which would enable for that image to be resized in the app and would enable for that black background to not show
