I kept running into the same problem on backend projects: emails arrive in all kinds of formats invoices, order confirmations, shipping notifications — and I'd write a regex parser that worked fine until the sender slightly changed their template. Then it'd silently break. LLM-based extraction fixes the brittleness but you still have to wire up the prompts, handle schema validation, manage retries, and get it into your backend reliably. It's a surprisingly annoying amount of plumbing for something that should be solved infrastructure. So I built ParseForce: you define a JSON schema, point a mailbox at your system, and parsed+validated JSON gets delivered to your webhook. There's a CLI for local dev (listen + replay), delivery observability in the dashboard, and idempotent webhook delivery with event replay for when things fail.
Free tier is 50 emails/month, no credit card. Would love feedback from anyone who's dealt with this problem — especially if you have a use case it doesn't handle well. https://parseforce.io
