We are looking to at the possibility of sending out small email blasts inviting recipients, who have already opted into our customers email lists, to view pURLs (personalized URLs) generated by my system. We are going to be sending them out via an SMTP connection to my Exchange 2003 box from an application called XMPie.
For obvious reasons, I am concerned about my system being blacklisted for spam and am hoping someone can help me get to the bottom of a small debate. Is there a particular threshold, in regards to emails sent, that we can stay under to prevent us being flagged as spammers?
I would appreciate other opinions but documentation I can present to the powers that be would be even better.
