Thanks for trying it out! You're right, I need to have more on the front page. I just added a quick explanation, but I'll have to work on my copywriting skills.

Thanks for trying it out! You're right, I need to have more on the front page. I just added a quick explanation, but I'll have to work on my copywriting skills. In retrospect, it seems a bit shady to make people type their email in to see what this is, but all I'll ever use your emails for is 1) to send login/activation emails and 2) to send things you POSTed to your endpoints. I built this out of frustration with those little edge cases where you want an app or script to be able to notify you by email, but don't want to leave your Gmail username/password lying around (often necessary with SMTP) or bother signing up and verifying a domain with one of the general-purpose transactional email services. I'm already finding lots of little uses for this.
