Don't waste my attention on the one-time setup BS. Show why it kicks ass in less than 30s.

I agree that it would be helpful to show a simple use case on the home page. Maybe I'm not the target customer (although I am a soloproneur), but your user flow of (1) user clicking a button, (2) plunk receiving an event, (3) plunk sends an email, isn't really a problem that I have, since sending an email after an action is taken is pretty easy to manage. Are you are focusing on categorizing users into groups and sending them progressive emails?

A very big part of what Plunk does is giving you the opportunity to link multiple events together and delay emails. You can extend it to users that have clicked button A and B but not button C and send those an email after 5 days. Significantly harder to implement and a lot of code that isn't really used elsewhere!

Definitely describe this use case on the site. This is an interesting feature that I didn’t think existed based on the current site material!

Yeah, makes sense

Features, sure. Common use cases solved by the features, even better.

I disagree with the comment that more is needed.

"User clicks a button - fire an event to Plunk - sends email" makes total sense to me.
