Microcenter kept sending me emails about receipts for purchases that weren't done by me

For a few months now, every now and then I would get emails for receipts from Microcenter in Tustin for items I didn't buy. It seems like the buyers of those items knew my email so they used it when they bought at MC, or it could've been they told the cashier wrong email or phone number by accident, which then was somehow accidently mine. I've bought at MC a lot of times, all using the same credit card and phone number/email. Is there a way to bind my credit card to the same phone number/email so that no one else can use mine again? Also, is it a bad thing that other people are using my email to send receipts to? like, can it gets me into something bad?
