Unfortunately, it does not seem to be working. :(
We had 22 people unsubscribe yesterday, 15 the day before that, and so
on. But today's unsubscribed list only returns 13 people. Looking at
the web page it shows all 13 people have unsubscribed today.
I have tried laving the "since" parameter blank and also tried it with
'2011-01-01 00:00:00' both just return the same 13 users.
Without the list of unsubscribed users we are starting to get
complaints from people that have unsubscribed but are now being
automatically resubscribed.
Note: since the resubscription is through listBatchSubscribe it seems
that MailChimp does not see that person as unsubscribed, but rather as
NOT subscribed.
I'm worried now. :(
