My experience with a free account is terrible. Basically because of the time it takes for an email to be sent to Mailfence and appear in your inbox. In some cases, it took hours. I conducted the tests from Gmail, Tuta, and Proton.

I bought a lifetime sub some years ago, and has used it for a couple of my projects.

While I would usually just set up the domain in my Proton/Tuta (or even just Cloudflare forwards), it’s nice to have a place where I can allow my team members to login, for the slightly bigger projects.

Only downside is that the owner can seem to lose his cool sometimes.
