Edit...
Just read the full thing. I'm now a very fucking angry customer. They are destroying basically all of the value their product had for me. I was raging and ready to comment on their blog post, but oh look they have comments turned off, how convenient, let's ignore our customers further.
Dear Mailchimp... Fuck you.
Since there is fuck all chance they will backflip on this, who should I migrate to, I've honestly been using mandrill for years and have no idea who offers comparable services because I was so fucking happy with mandrill I didn't need to look elsewhere... I hope a mandrill employee is on HN because if this actually happens they're going to lose 10 paying customer accounts when I find someone else hope your shitty management plan is accounting for loss of goodwill and loss of customers.
