Our take
Mailbox.org is the boring-in-a-good-way German option: a paid, business-friendly mailbox with custom domains and encryption that has quietly done the job since 2014. There is no free plan and the interface will not win design awards, so it suits people who value a stable provider under strong German privacy law over flash. If you want a dependable inbox that plays nicely with Thunderbird and you are happy to pay a few euros a month, it earns the slot.
