Comment Official Digital Mailboxes (Score 1) 78
Physical letter services can be replaced though. In Scandinavia, we have official digital mailboxes for important documents (government and businesses). It's not email, but another type of service.
Only certain types of private businesses (banks, insurance, etc) and government agencies can send you messages. Spammers and scammers are not able to send messages at all.
The mailboxes are free, but operated by private companies. You can only read the messages on the Web, or in the official app. You must use an official digital ID (with two-factor auth), but there are several digital ID platforms available. You're free to pick your own provider, but there are only two or three. There are fees for sending letters, but not for receiving them.
