Stop, I repeat STOP putting me on your weekly or monthly newsletter when I haven't asked you to. Just because I sat next to you at a networking event and gave you my card does not mean that we have a relationship. Do you even know that.... 1. I am currently receiving more than twenty newsletters that are just like yours?
2. I'm not even in the market for buying or selling a house?
3. My brother is a real estate agent so there's little chance that I would even use you in the first place.
When you send me unsolicited e-mail it is not an effective marketing campaign - in fact - it's the opposite. It irritates me and I don't trust you from the start. It's one thing if I've requested to receive your newsletter, but it's quite another for you to go to events simply to compile a list of names for spamming. (Yep - you're spamming.)
Do you have the guts (and the quality info) to make your newsletter opt-in only?
