My daughter uses an email address equivalent to DXterra (as in daughter xterra), whereas I use nothing equivalent to my name.
Over the years, she has gotten wedding invitations, requests for verification of purchases, etc. The most poignant was email from the Human Resources of a company congratulating the intended (as opposed to the actual) recipient for being hired. In that particular case, she found the company's phone number, calmled the HR department, and told the relevant person that they were sending the message to the wrong email address, and suggested that they call the new hire. She watched over several weeks as the messages got more and more hositle, and finally informed the new person that she was fired.
In the case of the wedding invitation, she politely declined but wished the new couple a happy and healthy married life.
The last message she received -- two weeks ago -- was to a name something like Frovpm Shperowrirt, as a name not an email address telling her that they were pleased she had stayed in the Houston Hilton.
How anyone got that from DXterra is anyone's guess.
