What it does
CubbyPost is a personal email-hosting project offering IMAP, SMTP, custom domains and catch-all addresses. It states that it operates without ads, tracking or selling customer data.
CubbyPost keeps the feature set close to conventional domain mail: choose an address, connect a standard mail client and optionally use a domain you own. Catch-all routing can receive addresses that have not been created individually, which is useful for separate signup addresses.
Its own page describes the service as a personal project and the current plan as free. Outbound transport uses opportunistic TLS, so the connection depends on the recipient server’s capabilities; that is not end-to-end message encryption. Consider the small-project operating model alongside the simple protocol support.
