Ability to mass validate emails before a Copilot Outreach

Related products: None

Currently when we send a Copilot outreach we get some failed contacts and some successful contacts from the live run. It would be nice to be able to validate emails before the live outreach via csv upload or even better to validate from the powerlist/outreach on a "Test" run. It is completely unmanageable to validate individual emails and update them one by one. So also having a way to mass update might be a good idea?
I can see how validating manually this way is painful. We could potentially show within a Power List who all are at risk of not getting emails (blacklisted or opted-out).





Thanks!
That would be very helpful. 
Manu,





Is there a way to run a report to see which all email addresses have been blacklisted or unsubscribed?
