My new site is ready to go live this weekend. Over the last 5 years, I have amassed a list of almost 10,000. I have always been very cautious when sending out emails as I don't what to look spammy. I am going to send a mail out in the next few weeks with an offer to all my subscribers as well as letting them know about the new site.
My question is, how many mailshots is too many, I have never sent out more than one a month. By the way, my site is an e-commerce site where the main objective is to generate orders.
