Is this going to affect MailChimp's deliverability? It seems like it would, my understanding is the reason most relays and blacklists are so lenient with MailChimp is exactly because of their double opt-in policy. Looks like they're ultimately throwing their long-term business under the bus for a short burst of extra cash.

Absolutely it will. If you use MailChimp and care about deliverability, I would recommend you begin looking at alternatives (if you haven't already).

  Don't most other providers already do single opt-in by default already anyway? Really, MailChimp is just sinking to their level. It's not all of the sudden worse than alternatives, right?

    > Don't most other providers already do single opt-in by default already anyway? Yes, most others have already switched to single opt-in. > It's not all of the sudden worse than alternatives, right? No, they aren't all of a sudden worse than the alternatives. They were already worse and they're certainly not going to improve as a result of this change. I manage several e-mail servers and will be watching very closely -- even more so than usual -- the amount of spam coming from MailChimp. I usually start out by blacklisting individual IP addresses but if this becomes a big problem, I will simply blacklist them entirely and be done with it. I've had two "incidents" in the last week or so with MailChimp that they have shown little interest in "fixing" (unrelated to this change) so I'm already inclined to do exactly that.

  I suggest the same dirt will attach to one's reputation if using Mandrill or Tinyletter, both of which are Mailchimp subsidiaries and share outbound address ranges.

It makes me wonder if they are trying to goose their revenue in order to sell the company sometime in 2018.

I'd assume so. More potential fake "subscribers" mean more bounced email and higher volumes which could be used as a early warning indicator for spam or reputation flagging. Slightly related, but I've noticed countless delivery issues with Mandrill, Mailchimp's transactional service. Their portal claims messages have been delivered, but many organizations relay back to us that their message never made it past the mail gateways.
