Ask HN: No-Code (Or Low-Code) Email App Templates?

Hi,

I've noticed the significant growth in no-code or low-code platforms lately (AirTable, Bubble.io) that can act as stand-alone applications or as a way to get to MVP quickly.

I specifically had an email app idea, but have had a tough time finding templates that could fit the "no-code / low-code" paradigm to test out my idea.

I'm reluctant to do more serious development too early, as I've seen that email apps can be hairy very quickly.

Any thoughts / guidance?
