There was an entire team called "ISP relations" whose sole job was to work with big ISPs when one of our IPs get blacklisted.
There was another team that would interview customers after their sending passed a certain threshold to see if they were following best practices. They would ask questions like
* How did you collect your e-mail list? * Did your users give explicit approval to receive list e-mails? * Did you acquire this list indirectly, from another company/campaign? (big no-no).
Usually everything was fine, or the customer didn't know they were doing something wrong, and they corrected it. But not infrequently a customer (who pays a decent chunk of money/month) would be told they can no longer use the product. Besides it being the "right thing" to do, having recipients block or report spammy senders worsens the reputation of IP addresses.
An interesting exercise would be to calculate the number of man-hours put into maintaining the reputation of each IP address.
Mailchimp isn't spam-free but it stops the spammer hitting you straight away and has human follow-up for problem cases. If that increases the price of sending mail, so be it.
(Apparently notifying someone they are in debt counts as spam to some)
I would love to understand better how to deal with it - and if there's a fellow HN user who understand the debt collector business, I would like to talk to them :)
>code4tee: The bit about calmly but methodically collecting a paper trail and then reading it back to them is excellent advice

Usually it's because one of our client's payment gateways is terrible and doesn't record all payments.
Really? My attempts to get unsubscribed from a mailchip spam list were largely unsuccessful until I spammed as many mailchimp employees as I could find on LinkedIn. Mailchip offers zero support for those on the receiving end of their garbage.
Honestly, the most absurd part is that mailchimp is opt-out by default. I never once got any sort of "verify you'd like to receive messages from this sender" sort of e-mail address. Obviously mailchimp has no incentive to make their delivery opt-in because it would cut down on the number of messages delivered.
And, yes, you're right most of the alternatives are just as bad (e.g. Google, Sendgrid) from an end user point-of-view. I've had no regrets about blocking sendgrid and mailchimp.
Self-hosting my mail stuff means I'd see if I were bouncing legit email pretty easily.
I normally use the link in the X-Report-Abuse header. I invariably get an automated reply immediately (so if this isn't happening for you something must be going wrong; this seems to have been introduced about a year ago).
This is followed by what appears to be a semi-automated response (it varies depending on outcome but the text is usually made up of mostly the same content). I've had human responses from replying to that. (Though there is rarely the need—the initial complaint seems consistently to remove the complaining address from the mailing list, so that campaign stops unless the spammer manually adds the address back. Why doesn't everyone do this? It seems pretty obvious.)
I've also blocked Sendgrid as, despite the occasional response from their abuse contacts, the campaign doesn't stop coming. (I can't get away with blocking Mailchimp in any case as I have users relying on legit mailing lists that use it.)

I think this is understandable in terms of customers wanting to move mailing lists from one ESP to another without having to re-opt-in every subscriber. I wish there were a better way to manage permissions for mail receipt, but the SMTP infrastructure is made largely of despair and tears.
I'm not saying a company is better just because they are more expensive, but I will argue you get what you pay for in this industry.
