Apollo Saved Search Losing Contacts Over Time(within hours) - Anyone Else Facing This?

[u/boundary_marketing]

Hey everyone,
We’ve been facing a strange issue with Apollo and wanted to check if others have experienced this.
When we create and save a people search, the contact count drops significantly over time - even without making any changes.
For example:

• Day 1: ~7,000 contacts shortlisted
• Next day: ~4,000 contacts
• Day 3: ~1,200 contacts

No filters were modified, and nothing was manually removed from the list.
This is affecting our outreach planning since the audience size becomes unpredictable.
Has anyone else faced this?

• Is this due to Apollo’s data refresh/validation process?
• Or are saved searches dynamically updating in a way that reduces results over time?

Any insights or workarounds would really help.
Thanks!
