inbox.eu is alternative which is much longer in business (since about 2000) with flat price per mailbox 9.99 EUR per year (now it is only 3 EUR with discount- no promo code needed).
It's also not clear what the jurisdictions of the company (I presume Latvia) and its data centers are.
This looks like a good option for semi-important communications if the need is just for a few mailboxes.
