Forward Email

Forward Email is a free and open source email forwarding service that lets you use any custom domain with your personal email address. It handles unlimited aliases and domains without storing your messages on its servers, acting purely as a relay. The project is built on Node.js and uses open standards like SMTP and IMAP.

The service supports wildcard aliases, catch-all addresses, and can forward to multiple recipients per alias. It integrates with any email provider that accepts forwarded mail, including Gmail, Outlook, and ProtonMail. Forward Email also provides a public API for managing domains and aliases programmatically. Everything is transparently auditable since the code is on GitHub under the MIT license.

This tool is ideal for developers, privacy advocates, and anyone who wants professional email addresses without paying for a hosted mail service. It was created by Nick Baugh and is maintained as a community project. There are no paid tiers or hidden limits, making it one of the most generous free email forwarding options available.
