Self-hosted custom-domain email on your own Cloudflare account. Inbox & outbox in your D1, REST API + webhooks, AI draft coming Q3 2026. No SMTP.

Having inbox data live entirely in D1 is great, but please add proper search with subqueries so I can combine sender and date range filters. Right now most basic email clients fall apart when you try to look for that one message from last week with a specific attachment. Even a simple endpoint like GET /messages?q=from:foo after:2025-01-01 would make a huge difference for anyone scripting against the API.
Since you're already using D1 for storage, adding end-to-end encryption with a per-user key would really set this apart for privacy-focused folks self-hosting email.
Finally got my custom domain email running on Cloudflare with this. The D1 inbox is surprisingly snappy for a serverless setup, and the REST API made hooking it into my own tools dead simple.
Congrats on the launch, this is a really clean approach to skipping SMTP entirely. One thing that would make it stickier for me is a built-in spam and phishing classifier running on inbound mail before it lands in the inbox, with a quarantine folder I can review. Right now the whole pitch is "you own your email," and owning it should also mean not having to bolt on a third-party filter to feel safe.
Cool to see Cloudflare-native email that skips SMTP entirely. One thing that would make this way more useful for me: built-in spam and phishing filtering rules so junk doesnt hit the D1 inbox in the first place.
