Verify Email Addresses in Real Time

I am using Lead Finder and had an overwhelming number of emails returned bounced or incorrect/invalid. I thought Lead Finder verifies email addresses??

If so, it would be great to verify emails in real time. I had to pause my campaign and cancel Lead Finder and use an alternative because of the number of bounced and invalid emails.

When leads are added to a campaign from Lead Finder, consider verifying emails in real time and only add emails that are valid and correct.
