"your Subscribers' email address, credit card information, purchase history" - These are super sensitive! It takes more than 3 months of legal process and convincing to get our customers to share these under strict data privacy clause. And here comes mailchimp and want to sniff it under the hood in the name of migration. They will literally land us in jail, if we don't migrate.
Yeah, this is a very big change in policy, and I suspect it might catch out Mandrill customers who don't read the fine print. The privacy policies for a couple of web applications I work with, for example, are incompatible with this new policy.
Guys, are you sure about this? Mailchimp subscribers and Mandrill users are not the same thing... Otherwise the Mailchimp cost would skyrocket, as they charge users in terms of subscribers amount
