Here's the email I just received when signing up (which I did right before Googling "Filepicker.io Hackernews" to find out more about HN's take on this service):

Hey - just wanted to reach out and thank you for signing up for Filepicker.io. I'm the developer assigned to help you get integrated, so let me know if you are having any trouble, want to know more, or just to say hi. It's always fun to hear from our users. -Brett van Zuiden

Simple. To the point. No pressure.

Now that I know that this was sent out manually by Brett instead of just another spammy auto-responder I like it even more.

I'd rather have a developer contact me and really want a reply rather than some HTML newsletter with tons of information and sales tactics on it.
