Verify your Apollo contacts before you send
Bounces from an Apollo list hurt every sequence that sends from the same domain. Check the list first: every address comes back valid, risky or invalid with a reason, from a live check with the mail server. Export the list as a CSV and upload it as it is; your Apollo columns are kept.
Free accounts get 100 free checks, then a plan covers it.
1. Export the list from Apollo
- In Apollo, open Search > People and filter to the contacts, saved search or list you want.
- Select the contacts, then click Export.
- Choose whether to export all selected contacts or only those with verified emails.
- Click Export records, then go to Settings > Import & Exports > CSV Exports and click Download.
- Upload the CSV below as it is. The email column is found automatically.
- Download the valid file and import it back into Apollo, or leave the invalid addresses out of your next sequence.
Apollo's help notes that exporting contacts you have already saved uses no credits, while net-new people are saved first and can use credits.

Common questions
- How do I verify Apollo contacts before a sequence sends?
- Export the contact list from Apollo as a CSV (Search > People > Export), upload it to SimpleVerifier as it is, and every address gets a live mailbox check. Import the valid file back into Apollo, or exclude the invalid addresses before you enroll the list in a sequence.
- What does it cost?
- One check per distinct address, the same as any upload. A free account gets 100 free checks; past that, a plan covers it.
- Does it use Apollo's email credits?
- No. SimpleVerifier checks each address itself. Exporting contacts you have already saved in Apollo uses no Apollo credits, according to Apollo's help centre.
