I really hate Mailchimp for not allowing me to use a spam@<i>domain.com</i> address. For starters, it is a valid email address. Shouldn't that be enough? I don't know what all those subscriptions will get me into so I first let them pop up in my spam box for a while and when it's good, I move them over.
Android Weekly is an excellent newsletter to stay on top of Android Dev news.<p>I have read each week's newsletter so far and always look forward to the next one.
