Invalid Emails
I am looking at cleaning our database on the invalid emails (we have alot and we have never looked into how we want to clean them up). We have invalid emails on the prospect side and client side, each would have to be different.
What are some ways you would clean them out, ideally we need to check first if they are invalid and thought putting them into a email campaign to see if they continue to be invalid would help us determine invalids further. We have smart lists built out for Hard Bounces (Invalid, Spam and Technical) but there might be a different smart list that would work better?
Any thoughts, or best practices?
