I think it's more likely if you use an initial in your email address. I have a fairly unusual last name, but I used my first initial to create my gmail address, so I regularly get stuff meant for a couple of other people.

Business cards or sheets of stickers are not going to solve this problem. The former is not universal, and you're not going to get enough adoption for the latter (do you really want to carry them around in case you need to put your email on a form?).

The only solution that might actually work is to put some kind of financial penalty on certain classes of email sender to incentivize reasonable levels of validation.

Yes. Or my name/address/phone number. It's essentially a machine-readable address label, the email is just one part of the vCard.

Do you people really not keep a book of stamps in your car? Such inconvenience!

I could overload my pockets carrying around all kinds of special purpose labels and stickers, and track my stock of them so I don't run out....or I could carry a pen.

No, why would I do that?
