Thanks for trying it out! You&#x27;re right, I need to have more on the front page. I just added a quick explanation, but I&#x27;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&#x27;ll ever use your emails for is 1) to send login&#x2F;activation emails and 2) to send things you POSTed to your endpoints.<p>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&#x27;t want to leave your Gmail username&#x2F;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&#x27;m already finding lots of little uses for this.
