Chargebee email verification with BillionVerify
Chargebee is a subscription billing and revenue management platform. Every subscriber in Chargebee has an email address used for invoices, dunning emails, and renewal notices. BillionVerify ensures those addresses are valid before they enter your billing system, reducing failed notifications and protecting payment recovery rates.
Why verify before the send
A bad email address on a billing account means missed invoices, failed dunning sequences, and lost revenue. Disposable or invalid addresses also signal potential fraud at signup. Verifying emails at the point of subscription creation helps you maintain deliverable billing contacts and spot suspicious sign-ups early.
Ready-to-use n8n workflow
Import this workflow into n8n — it verifies every address with BillionVerify before Chargebee sends, so only deliverable contacts are emailed. Install the BillionVerify community node first, then add your API key.

}Workflow templates with Chargebee
Ready-to-use workflows that verify emails before Chargebee sends.
How it works
- 1
A new customer signs up and Chargebee creates a subscription record with their email address.
- 2
A Chargebee webhook fires, triggering an n8n or Integrately workflow that calls the BillionVerify REST API.
- 3
BillionVerify checks the address for validity, disposable domains, role patterns, and catch-all status.
- 4
The result is written back to Chargebee as a custom field or metadata tag, and risky contacts are routed to a review queue.
- 5
Billing notifications, dunning emails, and renewal reminders are sent only to verified, deliverable addresses.
When to use this
Verify email at subscription creation
Before a new Chargebee subscription is confirmed, run the customer's email through BillionVerify. Block or flag disposable and invalid addresses to prevent billing contacts that can never receive invoices.
Improve dunning email deliverability
Failed payments trigger a series of dunning emails. If the address on file is invalid, those messages never arrive. Verifying addresses at signup — and periodically re-checking — keeps your dunning sequences reaching real inboxes.
Audit subscriber lists before revenue reporting
Run your Chargebee customer export through BillionVerify's bulk API to identify undeliverable addresses among active subscribers, then prompt those accounts to update their contact information.
FAQ
Can BillionVerify integrate directly with Chargebee webhooks?
Yes. Chargebee webhooks can trigger n8n workflows using the BillionVerify community node, or you can set up the connection via Integrately for a no-code approach.
Does verifying emails help reduce churn?
Indirectly, yes. Reliable delivery of renewal notices and dunning emails means fewer accounts lapse due to missed communications — keeping payment recovery rates higher.
How should I handle subscriptions where the email fails verification?
Tag the Chargebee customer record, suppress billing emails to that address, and trigger a separate in-app or SMS prompt asking the subscriber to provide a valid email.
Can I verify addresses for existing Chargebee customers?
Yes. Export your customer list, run a bulk verification through the BillionVerify API, and update records with the results to clean up your active subscriber base.
