Ask HN: 2023 way to do contact form

I'm about to launch my revamped business web site; the old one got blown away along with a cancelled dedicated server in a colo, backups forgotten.

I'm a little late to the public cloud party, you might say, but better late than never. I'm hosting the new site in an S3 bucket fronted by CloudFront.

My natural instinct would be to wire a contact form to a mailer running on the web server hosting the site, which, as we know, is so Jurassic an impulse as to be wholly ruled out in this brave new serverless world. Putting such functionality in Lambda gives me the sense of taking a labourious detour to reinvent some kind of wheel, since people with far less technical acumen are throwing up contact forms every day.

I have experience with some third-party overlay products for contact and engagement, e.g. www.livechat.com. Maybe I'll come back to that idea, but today I want a contact form that generates an e-mail, or perhaps calls a webhook/POST-back.

I'm embarrassed to say, I don't really know how to get a high-quality contact form going in a truly turn-key, serverless, 2023 way. Recommendations appreciated!
