Ask HN: Feedback on our CLI and API for email automation?

We're working hard on making email easier to program against. There are a lot of solutions out there to send emails programmatically (sendmail!), but not that many for inbound.

Would love some criticism and feedback on our https://docs.mailscript.com and our API playground at https://api.mailscript.com

If you're a dev who wants to hack around email, how can we make life easier for you? How can we improve our tool to facilitate that?
