I'm glad you've reached out for clarification. Do you currently have an active account with Rogers? Typically the communication and invoice emails are sent from a firstname.lastname@example.org address. Does the email include any contact information for an individual? If yes then we can definitely verify employment for you.
Would you be able to share a screenshot of the email? Please ensure you erase any personal info from the image before you upload it on this thread.
email@example.com is NOT a legitimate email. they will never email you from a email you do not recognise or never use the consumer @rogers.com domain, if anything they will use their corporate domain @rci.rogers.com instead.
