Thanks for the update Trena, and glad you took the plunge
I've moved you over to a new thread as it's a great topic.
Remember when it comes to emailing previous clients, as long as it's not to regular it doesn't matter if you don't hear anything back. If everyone unsubscribes, then that tells it's own story, but we have people who upgrade years after first listing with us, and have received numerous mails without any response.
A lot of the time it can be your mindset, mood or requirements at the time when an email arrives. If I'm in need of my carpets being blitzed when your mail lands, I'm likely to get in touch. Otherwise it's filed away in the subconscious. If I never want to hear from you again, I'll unsubscribe.
Be very interesting to see how it goes. I imagine time and effort to sort out the mail will be recouped by 1 job, so in theory it's pretty cost effective marketing.
