We have had a number of people who have unsubscribed an email address very similar to another address in our lead database. Example scenario: 
- 
		I send an email to John Doe via "jdoe@example.com"- in the database as subscribed
- 
		John gets the email routed through his other alias "doe@example.com"
- 
		John unsubscribes the alias I do not have a record for =  "doe@example.com"
- 
		I send another email to jdoe@example.com, the subscribed alias
- 
		John calls me irate because I sent him an email after he "unsubscribes"
I know we could have used the unsub form better which is being fixed. But is there a way to run a report on email addresses with the same domain so I can see if there are other potential John Does out there?
Thanks!
