In Switzerland, the public post company provides a service[0] which scans your incoming letters (i.e. their content, not just the envelope) and makes it available via the web and an app. I started using this service last December and am very happy. Kinda looks like I am forcing digitalisation upon organisations who don't want to make progress on it :D
It costs 9.99 CHF per month, hence within the limit of the post, and very much worth it.
