Calley email verification with BillionVerify
Calley is an automated call dialer that helps sales and support teams reach large contact lists efficiently. Integrating BillionVerify into your Calley workflow ensures that every email address tied to a contact record is valid and deliverable before you invest call time, keeping follow-up email campaigns and contact data accurate.
Why verify before the send
Sales dialers live and die by contact quality. When email addresses attached to Calley contacts are invalid or disposable, follow-up email sequences bounce and sender reputation suffers. BillionVerify scrubs those addresses before they enter your dialer queue, so every contact you call also has a reachable inbox for multi-channel follow-up.

Ready-to-use workflows that verify emails before Calley sends.
How it works
- 1
Export your contact list from Calley or capture new contacts via a webhook.
- 2
An n8n workflow loops through each contact and sends the email address to BillionVerify via REST API.
- 3
BillionVerify returns a deliverability verdict for each address.
- 4
Valid contacts are kept or flagged as safe; invalid and disposable addresses are removed or quarantined.
- 5
The cleaned list is re-imported into Calley or synced to your CRM for multi-channel follow-up.
When to use this
Validate emails before importing contacts
Before uploading a contact list to Calley, run it through BillionVerify via the REST API or n8n. Remove invalid, disposable, and role-based addresses so your call list and any associated email outreach start with clean data.
Enrich dialer records with email health scores
After a call, when reps collect or update email addresses, trigger a BillionVerify check through n8n. Store the verification result alongside the contact so marketing teams know which records are safe for email follow-up.
