So, I'm an independent consultant and work with a mortgage company. My job is to connect them with real estate agents for referral business. They can do things no other lender in the surrounding states can do which is close deals in less than 2 weeks. I have a list of 45,000 real estate agents I would like to email about this mortgage bank. A. If the email contains all of the mortgage company information, compliance number, etc. Is this safe to do? B. Could this still be considered as spam even though it's directly related to the needs of the recipient? C. Would it make any difference if I sent them all at once or 1,000 a day for 45 days? I've never send a big blast email before and I want to make sure I understand all that is involved before I do.
