I want to exclude all of the non-mailable leads from all e-mailing Smart Campaigns in future, so they won't even be qualified to run through the flow and won't be visible in "Schedule" tab. Is there a safe and smart way to do this? Any best practices?
Case: We have a pretty big database in Marketo, but a huge part of it is non-mailable (Unsubscribed, Email Address is empty, Email Invalid etc.) forming this annoying number that appears when i schedule a Smart Campaign: "set to affect 500K leads, 30K leads are blocked from mailing". It prevents us from seeing the actual number of leads without calculation, and also increases the campaign count time.
Thanks!
