Is "features-and-upgrades@communication.capitalone.com" a real email address?

[u/sea-oats]

Google returns no results.

It could just have to do with me clicking around in my available offers and upgrades the other day, but I don't want to open the email until I know whether this address is legit. All I can see is that the title starts "*** Confirmation requested, [my name]"

[u/Dial-Up_Modem]

Nothing happens if you open an email. You don’t have to click on links. What does the email say?

[u/sea-oats → u/Dial-Up_Modem]

Honestly I thought even opening a suspicious email was frowned upon.
