Apollo Email Verification
Verify Apollo prospects before you reach out. Connect your Apollo account, verify every email address, and push clean results back, all automatically.
Apollo is a sales intelligence and engagement platform with a large prospect database. Mailthentic integrates directly with Apollo to help you verify and clean your contact database without CSV exports or manual work.
How It Works
Four steps to a clean Apollo database.
Connect Apollo
Paste your API key once to connect. No password sharing.
Import contacts
Pull contacts or lists from Apollo. Duplicates are removed automatically.
Verify every email
Each address runs through the 9-point engine including SMTP mailbox confirmation, catch-all and disposable detection.
Push results back
Clean results sync back to Apollo. Invalid contacts are tagged so you can exclude them from campaigns.
Why Verify Your Apollo Contacts
Protect your sending domain
Cold outreach to invalid prospects bounces and damages your domain reputation.
Higher reply rates
Mailing only reachable prospects improves connect and reply rates.
Cleaner sequences
Remove invalid addresses before they enter your sequences and skew metrics.
Real-time verification
Verify exported lists in bulk or check addresses via the API.
