In a similar vein, but with physical mail, I made a donation to the local PBS TV station years ago during one of their fundraisers. They sent me a postcard with my name misspelled in a way I had never seen before. I then received solicitation mails from several other charities with the same misspelling. Nothing says "thank you for your donation" like being sold out for a few extra dollars. I never donated to them again.
