Tool Open source
Mailflare is a self-hosted email inbox for custom domains, built on Cloudflare. It provides domain connection and Cloudflare Email Routing setup, personal and shared mailboxes with delegated access, message composition and receiving with attachments and rich formatting, and organization tools such as search, folders, stars, snoozing, archiving, spam, and trash. Routing rules can store, forward, reject, or categorize incoming messages.
When deployed to Cloudflare, Mailflare uses Email Routing for inbound delivery, Cloudflare's email service for outbound messages, a D1 database for mail data, and an R2 bucket for attachments. It can also run as a Docker container using SQLite and local files, with a built-in SMTP listener or a Cloudflare relay Worker for inbound mail and an SMTP relay or Cloudflare Email Sending for outbound mail. The project also includes account and permission management, API keys, webhooks, audit logs, backups, import and export, contacts, and sender blocking.
