I use very unreliable email forwarding services for protection and control. Rationale:

• to detect data leaks (every email address I disclose is unique to the recipient)
• to disable an ephemeral address when it is abused

I pay no fees. My forwarding providers are likely running in some kid’s mom’s basement. Lots of messages get lost. It’s usually the worst kind of a loss: a blackhole. Which means the sender successfully connects and receives a well-sent status. The messages are lost after the sender is left with the false idea that it was delivered. I have no idea if the messages are lost by the forwarding provider or the email server of the ultimate destination.

In one case I discovered that a forwarding provider was silently dropping all messages no matter what email service I use. It’s a gratis service, so the idea of suing or taking action against the shitty provider would be controversial and likely unsuccessful. It could have been happening for months or even years before I discovered it was happening.

Email is inherently unreliable. It is what it is. But at the same time, Belgium has decided that sending an email carries the legal weight of a registered letter. Yikes! Indeed, something officially important for which my attention is critical and has legal consequences has a good chance of going to a black hole without my knowledge.

To worsen matters, the post service charges ~€10 to send a proper registered letter. That extortionate cost sufficiently drives senders to use email instead.
