Baserow email verification with BillionVerify
Baserow is an open-source no-code database and spreadsheet platform that lets teams build and manage structured data without writing backend code. Pairing it with BillionVerify ensures that any email addresses stored in your Baserow tables are real, deliverable, and safe to contact.
Why verify before the send
Baserow tables often serve as the source of truth for contacts, leads, or subscribers collected from forms and imports. Without verification, invalid addresses, temporary inboxes, and role accounts accumulate over time, driving up bounce rates whenever you send from that data. BillionVerify cleans the list before problems compound.
Ready-to-use n8n workflow
Import this workflow into n8n — it verifies every address with BillionVerify before Baserow sends, so only deliverable contacts are emailed. Install the BillionVerify community node first, then add your API key. Adapted from this n8n template

How it works
- 1
A new row is created in Baserow — from a form submission, import, or manual entry.
- 2
n8n detects the new row and extracts the email address field.
- 3
The BillionVerify community node checks the address for validity, MX records, disposable domains, and catch-all status.
- 4
The verification result is written back to a dedicated field in the same Baserow row.
- 5
Downstream workflows or views filter on that field to ensure only verified contacts are contacted.
When to use this
Validate new form submissions on entry
Trigger a BillionVerify check via n8n each time a row is added to Baserow through a public form. Update a status field with the verification result so your team knows which contacts are safe to reach.
Audit existing contact tables
Use BillionVerify's bulk API to sweep through existing Baserow tables and mark each email as valid, invalid, disposable, or catch-all — giving you a clean, segmented contact base without leaving the data in Baserow.
Gate outreach campaigns at the source
Before any email campaign pulls recipients from a Baserow view, an automated n8n workflow can re-verify addresses that haven't been checked recently, catching emails that have gone stale since they were first collected.
FAQ
Can I verify emails already stored in Baserow?
Yes. Use n8n to iterate over existing rows and call BillionVerify for each address, then write the result back. Bulk API mode handles large tables efficiently.
What verification statuses does BillionVerify return?
BillionVerify returns statuses including valid, invalid, disposable, role-based, and catch-all, so you can segment contacts rather than simply accept or reject them.
Does verifying emails slow down form submissions?
Verification can run asynchronously after a row is saved, so there is no noticeable delay for the person submitting the form. The status field updates in the background within seconds.
