Hi List

We again face problems with services by MailChimp.

Their platform is equally fashioned by serious companies sending
permission based newsletters and by very persistent repetitive spamer.

They repeatedly get blacklisted on our platform, because of recipient
complaints.

Then repeatedly customers having subscribed to newsletters from serious
companies complain to us, because mailchimp is blocked by our anti-spam
services.

The customer reporting spam are not those who subscribed to
newsletters, forget about it and them report opt-in emails as spam.

No, the problem is that MailChimp operates under 'US' marketing laws
where the sender is only obliged to provide an 'opt-out' link in spam he
sends and does not have to require the recipient to have a validated
opt-in to get advertisement emails.

So often, the spamers use harvested email addresses (even spamtraps we
have hidden of websites) or lists they bought online.

The other problem is about GDPR, where laws in most European countries
require the sender of advertisement to disclose the source of data of a
recipient to this recipient.

Spamers sending email over mailchimp are clever. The links in the email
point to some anonymous redirection services to mailchimp themselves or
to domains registered via anonymizing proxies. Payment work over
paypal and if you have been trying to get at the identity of a fraudster
who took money via paypal, you know this is not possible. So the
recipient of spam needs to contact the 'sender' aka MailChimp and
requires MailChimp to disclose the identity of the sender, which
MailChimp then again rejects pointing to US privacy laws which require
them not to disclose the identity of their customers. Safe Heaven for
Spamer!

MailChimp does close accounts for which they get a certain number of
complaints, but they fail to recognize and block the same spamer who
repeatedly opens news accounts.

So what do you think should ISP and Email Plattform operators do about
MailChimp?

* Tell the customers complaining about spam they have to live with it?
* Block MailChimp and tell serious companies who get blocked as
  collateral damage, to look for another, not so spamer firendly ESP?
