The unsubscribes? Or the “I never signed up for this” count
On the unsub front, only ~30% of our mailing list engages with sends (opens the email), and I’m willing to bet up to 50% of our mailing list is “dead” emails, so really it’s 2-3x that number in practice. We have CASL to comply with so we aren’t willy nilly with adding people to our list either.
