What is emailflare?

EmailFlare bundles two separate email products. The emailflare-api is a REST API for sending transactional mail through Cloudflare Email Sending, with scoped keys, 50 React Email layouts across five themes, domain management, send logs, suppression lists, and a React admin panel. The emailflare-inbox is a team inbox and lightweight CRM that receives inbound mail via Cloudflare Email Routing, offering conversation threading, replies, automated sequences, and contact management. Both products deploy primarily as Cloudflare Workers (zero-ops, edge-native) using Cloudflare's database, cache, storage, queue, and durable object services. Docker self-hosting is a secondary option with single-container images using embedded SQLite (mesahub-core) and optional Redis for the inbox. The Docker path needs a Cloudflare account for production sending, while test API keys capture mail into an in-house Test Mailbox without external credentials. Licensed MIT.
