Hi,

Apparently none of the other RBLs consider it spam.

I've asked the list a few times before about similar companies, such
as verticalresponse.com, which are also mass e-marketers, and I doubt
very much whether all recipients have signed up for their
"newsletters" or "webinars".

There wasn't really any consensus on the list for this sender either.
I've left them off my blacklist for now, despite seeing messages
pertaining to "hair care" and gutter cleaning from their customers.
They're also not on any public blocklists.

How many of those are now on the dbl or zen?

Yeah, I saw that too. Their response to me would be to figure out a
way to only let their legitimate stuff through. I could probably also
make some noise to get a contact there through my customer, but it
would probably only lead to lip service. I'd never be able to get them
to switch providers, and as we've seen with verticalresponse, the
alternatives have issues too.

I just figured that since it's immediately being dropped, perhaps
sending them a bounce would help to control the number you receive
from them, if not just firewall their block outright.

That's because you don't do business with them, so anything received
is unsolicited. In my case, corporate communications are actually
being blocked.

I'm going to keep a closer eye on them, and manually inspect more of
their mail to figure out what to do next.

Thanks,
Alex
