I use the email address firstname dot lastname at gmail. I estimate that some two hundred individuals share my first name and last name globally.
About once or twice per month, I get an email that is clearly intended for a name-cousin of mine. I've been signed up for college alumni newsletters, have been sent offers for house repairs, reminders for soccer practice, bills, receipts, sign-up confirmations, and even have received a job application.
What is the proper etiquette in handling such an email? Should I just delete them or would it be appropriate to reply to the sender explaining the address mix-up? What can I do when my email address was used to create an account?
