I have a first.last@gmail.com too with a reasonably uncommon South Asian name (+ unusual spelling). I’ve received bank account registration emails, Income Tax registration details, and someone has even registered an Indian government biometric ID (Aadhar) with my email. Even elevator servicing invoices (one of these people is an apartment super, apparently). Clearly many of these systems have bothered with email validation. Sending polite emails to these organisations mostly hasn’t worked. The only time it has worked has been, oddly, the elevator company, because I emailed someone at their privacy team in their world HQ in Finland.
