Overview
Filters allow you to include or exclude specific subsets of data when you search for new Contacts or Accounts in Apollo. This helps you to better segment and personalize your team's approach so that you can find and engage with the right contacts at the right time.
You can access many types of Filters in Apollo.
Apollo divides all Filters into 6 main categories: Settings Filters, Person Info, Company Info, Engagement Activity, Created Source, and Miscellaneous.
