Best alternatives to Mainly in 2026
People who run their own domains, or several small projects each with their own email address, often end up juggling multiple webmail logins or a heavyweight desktop client just to check everything in one place. Mainly is a self-hosted webmail client built specifically around that situation: one interface, multiple domains and mailboxes, unified into a single inbox list. Mainly is open source and deploys via Docker with a Postgres backend, so it runs entirely on infrastructure you control rather than a third-party inbox provider. It's built for speed and pulls mail from multiple mailboxes across different domains into one unified list rather than requiring you to switch accounts or tabs, and it's designed to be highly configurable for people who want to tune how their mail is organized. Being self-hosted, there's no subscription fee and no third party reading your mail metadata — the trade-off is that you're responsible for running and securing the deployment yourself.
