To get your data removed, the data broker or company must know who you are, Usually, the removal request includes personal identifiers such as your name, email, address, phone number, or other details they hold.
Incogni sends multiple requests to different brokers on your behalf,
If a broker doesn’t have your data, they might reply “We don’t have this person’s data,” but the removal request itself often includes your full details to identify you.
So effectively, you might be sharing your full personal info with companies you never contacted yourself, just in the removal request.
This creates a risk: those companies may now have your info, even if they didn’t before.
Email is more tricky and Extensions like SpamAssassin, Mailwasher maybe an option ?
