> Our whole service was built around the premise of giving email liberties back to the users, not taking them away. We refuse to fence users and lock them in.

This is a very interesting take! I completely agree with it. While it may not work for many but one of the biggest mistake I made was I've used <4 letter name>@mailbox.org extensively. But I am making an active effort to change that and remove it from use completely.

This is kind of a hidden lock in. Because there's no free email service unlike Tutanota where you can keep using email on their domain in reduced capacity.

Same for Posteo. It just doesn't make sense.

I will eventually move away from Mailbox. I will be watching Migadu. Though 20/day out can be limiting. Though it's rare I've sent 20 mails per day but there has been days when I did.

I do not agree with the tone here. Yes, IMAP doesn't support 2FA but I'd want the Migadu control panel interface to be protected by 2FA. I like how Mailbox has handled it.

Foe example there's a 200 email per day "limit" on the cheapest plan, but each plan comes with a 25% tolerance.

Similarly the storage "quota" on each tier.

I just asked Migadu's support about whether there was a 10GB option available, as 5GB was too small for mea and 30GB too high / costly. "Sure," he replied in under 4 minutes - "there's actually no fixed storage limit on each plan, please see https://www.migadu.com/pricing/#how-do-storage-limits-work" And sure enough - 5GB, 10GB, 15GB... all would be possible on the "5GB tier".

If you get close to or exceed the 30GB quota of the next tier up, their systems contact you and suggest upgradng which sounds pretty reasonable.

I'm just going to check if Apple or Google are quite so accomodating...
