Prevent getting marked as spammer

[vbcode1980]

Thats simply not correct. /you can get yourself removed from spam blacklists if you contact your ISP and are able to prove you have a legitimate business purpose for sending large quantities of mail.

At my previous place of employement (quite a large organisation) we had to stop using e-mail for these kinds of things because the ISP would block it. They couldn't be pursueded to release the block..

The solution to that problem is simple; find another ISP or upgrade the service :P. Large organisations generate huge volumes of email traffic, whether it be from individual employees or as part of a marketing campaign.

I would not be surprised that if the service an organisation is paying for does not include an agreement to host such mass mailing events, then they will be blocked from doing so.
