We have 8000 contacts in SF which have been collected from events attended over the last 10 years. Since moving over to HS, I have imported the whole list with the aim of sending a mailer to see which emails bounce in order to clean up our contact DB. Sent out a 1st mailer yester and it was stopped by HS due to high bounce rate. What tools do people recommend for =validating and cleaning a list of 8000 contact emails?

Hi, @alassman. I've never had much luck with email validation services - they're usually a mixed bag of mediocre results. @MFrankJohnson recently asked about a similar topic, and might be able to provide some additional insight.

I liked ZeroBounce.net they seem the most credible & thorough. But now the question is: how do the "different kinds of bad" get fed back into HubSpot? I also started with 10 years worth of Salesforce and Outlook and business cards.
Now I have my results. What different ways does Hubspot recommend handling
spam traps (sounds like a blacklist)
abuse (some of our friends don't realize our company domain's changed)
invalid (real relationships, bad email)
There seem to be 3 big buckets in HubSpot:
Custom "but not" List logic (Like all lists have a final ..but not at a competitor domain...but not at a defunct domain)
