So I have a couple of forums that I'd like to send email blasts to but after trying it out on a couple of my smaller ones (approx 2k members) my servers' emails got banned by Microsoft emails (hotmail, live, outlook).
After a couple days my server is now unblocked but I'm afraid to continue with my bigger forums...
Is there anyone I can do this without getting blacklisted by Microsoft?
And to top it off... with MS, even if the emails don't bounce - if to many users mark it as spam (instead of simply deleting it or doing a filter to auto-delete any of them) guess what happens also. You get blacklisted.
