Mailing list - or how to get free stuff!

Visitors to my blog/website (wickedchrista.com which redirects to wickedchrista.blogspot.com) may have noticed a newsletter sign-up box at the top of the right sidebar. Quite a few of you have already signed up (I'm amazed because after more than a year of telling people they could email me and I would email them notices, I still only had six such subscribers - a week with the mailchimp sign-up and I have over thirty).
Some of you may be wondering whether you need to sign up. I know, right? After all, Amazon has a subscribe to author feature now, as does Apple. Probably other sites do, too. But, here's the why behind the "yes, you should." Amazon can't give you a free deleted scene from Curves for Two or a POV switch up from Curves for Her Billionaire Doms (what, you don't want to get inside Hunter or Daniel or Aldon's head?) or an epilogue to another favorite. Some of these added scenes won't go public (at least not by me), others won't be free when they become publicly available weeks or months later.
So, free stuff before the rest of the world can even buy it is nice, so long as this doesn't turn into a daily email pimping this title or another, right? I've got you covered on that, too! (See how sweet I am. :D ) I promise I'll only send a newsletter out if I have a new release (including collections of older titles or print/audio versions of older titles), a sale to announce or a gift!
