First of all, 2% is not at all a "high unsubscribe rate," especially
for a list that has been dormant for a couple of months. I'd expect
the unsubscribe rate to be higher than that.
And ONE complaint out of 4000? And you even pointed out yourself that
the subscriber was probably confused by the domain change.

I believe you overreacted, though there's certainly no harm in it. At
least, not at this point ...

This client is more forgiving than most.

This is, as Dave pointed out, totally insignificant. I run a large
mailing list with a confirmation loop, and I *still* routinely (well,
a coupla times a year) receive "complaints" from people who claim
that I am spamming them. My guess is, most often it's a child or a
sibling or even a friend who has access to the mailbox and does the
subscribing -- possibly as a joke -- and the poor clueless mailbox
owner then starts receiving what he thinks is spam. Many seem to be
too daft to figure out the unsubscription instructions that are
included in the footer of EVERY message (most probably don't read
down that far), and it's easier to simply reply and tell me that I'm
I have a form letter I send them which includes unsubscription
instructions; I rarely hear from them again.
Three such complaints on a newly-moved list out of more than 18,000
delivered e-mails isn't even worth noting, Sharon.
>The problem is what do we do about this?
Move his list. If it helps you sleep at night, require everyone to
re-up to the list. But I think even that is an overreaction. The
numbers you've quoted are really pretty good.

I think your complaint rate would be MUCH higher if that were the case.

Sharon, no list of any reasonable size will be 100%. As I said, even
confirmation loops aren't perfect; if someone else has access to the
mailbox, then all bets are off.
