Hello @SpencerU,
This is a great time to do a Contacts Database Clean-Up. We have a few HubSpot Academy Projects targeted to walking you through cleaning up your database.
I have listed them below:
- Contacts Clean-Up Project
- Setting-Up Your Database correctly (Module-highly recommend)
- Six Ways to Keep your Data clean
With the contacts that have bad email addresses, I would remove them from your database or send a campaign to clean-up those lists. You can follow the steps to do that here.
Please let me know if you have any more questions.
All the best,
Courtney Sembler
Inbound Professor
