Key points
- Cloudflare Email Routing forwards incoming mail but lacks sending.

The Quest for Custom Domain Email
The author sought a custom email address for their domain, jacobg.co, aiming for a solution that supported their own domain, offered low pricing, provided unlimited addresses, ensured verified sending and receiving, and integrated with Apple Mail. This search spanned over two years, driven by a desire to avoid expensive, underutilized services.
Cloudflare Email Routing Limitations
Initially, the author explored Cloudflare's Email Routing, a natural choice given their site's hosting on Cloudflare Pages and DNS routing through Cloudflare. This service effectively forwards incoming emails to a personal inbox, allowing addresses like "[email protected]" to receive mail without additional mailbox costs.
However, Cloudflare's solution proved inadequate for sending emails from the custom domain. The primary design focuses on forwarding, and the available options for outbound mail were either too costly or overly complex. Additionally, forwarded messages occasionally experienced delays, taking several minutes to arrive.
Mailflare: An Open-Source Alternative
The author then discovered Mailflare, an open-source, self-hosted email inbox project by hieunc299 on GitHub. Mailflare utilizes Cloudflare for receiving mail and integrates with Resend for sending, providing an interface for message management. This setup appeared promising as it was open-source, leveraged existing infrastructure, and avoided the need to run a traditional mail server.
Despite its theoretical appeal, Mailflare presented practical challenges with outbound email reliability. The complexities of domain authentication, sender reputation, and how major providers like Gmail and Yahoo evaluate incoming messages made the setup unreliable for personal email use.
