subscription plug in, automatic notices?

Hi, sorry to post this but I couldn’t find this by searching. I’m looking to add a “subscription” type plug in. It seems that many of these require people to submit emails and then I have to send out an email. People are hesitant to give out their emails as it is but I’m looking for one that may send out automatic emails when I publish a new post. Does such a plug in exist? If not, is there a plug in that can be recommended that I also do not have to give out my personal email address when sending to subscribers? Thank you!
