Good idea! We will add it!

I'd love this service but how are you going to handle bots? I wanted this for my personal website which will maybe receive an email once per month in the best case scenario, but with lambdas there is always the risk of having a malicious actor coming in and pushing your bill to astronomical levels

That's what I did here: https://www.simplecontactform.org The presentation isn't fleshed out because we mostly use it for our agency clients but it is the most minimal version I could come up with.

I always liked the idea for your service but the pricing didn't work (to be clear: it's not your fault, I'm not sure it is solvable). I wanted to use it for my personal website which will receive maybe 10 emails through the year (if I'm lucky), but at $5/month I can just spin up my own VPS, which can do way more than sending me emails.

That makes total sense. I set this up for our agency clients to be able to integrate email sending on a static site without having to manage a server or dive into spam filtering. For them the decreased complexity and time saved alone is usually worth the price.

I see! Makes sense, thank you for the response
