As someone who has no knowledge or interest in your project, I will say that starring can be anything from "I love this project" to "Looks interesting, maybeee I'll take a look at this in 6 months". There is no guarantee of fandom. Finding the email of someone who starred your repo and auto-subscribing them to your email list is in poor taste. It's the software version of that person who suddenly adds you on Facebook, LinkedIn and Twitter the same day you briefly said Hi to them at some event, and then sends you an email saying "Hi!" just in case. I would request you to please stop doing it, and not contribute to this slippery slope of treating your open source project as a marketing exercise.
