Mailflare

Mailflare is a self-hosted email application for individuals and teams using custom domains. It runs on Cloudflare Workers infrastructure, storing mail data in your own D1 database and attachments in R2 buckets. The platform offers a complete inbox experience with send/receive capabilities, rich formatting, attachments, drafts, folders, search, and snoozing—replacing basic email forwarding with full functionality.

Designed for professionals and teams, Mailflare supports unlimited domains and mailboxes, shared team inboxes, individual accounts with delegated access, two-factor authentication, spam filtering, scheduled backups, and import/export. Additional features include routing rules, real-time notifications, contact management, API access, webhooks, and an AI assistant for mail search and draft preparation. The project is fully open-sourced and deployable with one click to Cloudflare Workers or Docker.
