I am sending mails with Mandrill api in php. I create templates on MailChimp and then export them on Mandrill.
The visualisation is ok, and when I copy / paste the html-css code in a local file, everything works fine and it's beautiful.
When I send a test mail with MailChimp, it's ok too. But when I send a real mail / test mail with Mandrill, margins are gone :
the good one in local and the wrong margins one
Does anybody why is this difference ?
Thanks a lot
EDIT
I need to add that in Thunderbird i don't have margins problem anymore
