Gocanvas email verification with BillionVerify
GoCanvas is a mobile forms and data-capture platform that replaces paper-based processes with digital forms, inspections, and work orders. Field teams submit forms containing contact details, client information, and sign-off data — all of which may include email addresses that need to be accurate for downstream communication and reporting.
Why verify before the send
Email addresses collected through GoCanvas forms in the field are prone to transcription errors, temporary emails entered to bypass validation, or outdated contact details. BillionVerify validates these addresses the moment a form is submitted, ensuring that notifications, invoices, and follow-ups reach real inboxes rather than bouncing or disappearing.
Ready-to-use n8n workflow
Import this workflow into n8n — it verifies every address with BillionVerify before Gocanvas sends, so only deliverable contacts are emailed. Install the BillionVerify community node first, then add your API key.

How it works
- 1
Connect BillionVerify to your GoCanvas workflow using n8n, Integrately, or the REST API to intercept form submission data.
- 2
Extract the email address field from each submitted GoCanvas form and pass it to BillionVerify for verification.
- 3
BillionVerify checks the address against SMTP servers, disposable provider lists, domain validity, and catch-all detection.
- 4
Receive a structured result — valid, risky, or invalid — and route the form data accordingly in your workflow.
- 5
Send follow-up emails, reports, or notifications only to addresses that passed verification; flag the rest for manual review.
When to use this
Validate client emails on form submission
When a field technician submits a GoCanvas work order with a client email address, verify it in real time before triggering any automated follow-up. This prevents failed delivery of completion reports, invoices, or satisfaction surveys.
Screen inspection report recipients
GoCanvas inspection workflows often auto-email reports to site contacts. Verifying recipient addresses before dispatch reduces bounces and ensures compliance documents are confirmed delivered to valid inboxes.
FAQ
Can BillionVerify handle verification in offline or low-connectivity field scenarios?
Verification requires an internet connection to the BillionVerify API. The check is best placed server-side when the form syncs back after the field submission, rather than on the device itself.
What if a client enters a catch-all domain email?
BillionVerify flags catch-all addresses distinctly. You can choose to accept them with a warning, request a secondary confirmation, or route them for manual review before sending important documents.
Does verifying emails help with compliance and audit trails?
Yes. Knowing an address was verified at submission time adds a layer of assurance to your audit trail, demonstrating that delivery attempts were made to validated contacts.
