Last Friday evening, having dinner out with my wife, I received an email on my Blackberry from a client that had purchased property through me many years ago.
After all those years he still had my email address and I had not changed it.
He had moved several times and he had changed his email address each time he moved. I had lost tract of him due to the changes.
The moral; don't change your email address! When you enter the real estate business, buy a domain and an email address and keep it. If your brokerage insists that you use their email address, have the email forwarded to your permanent email address.
