Auto-verify new Airtable lead emails with NeverBounce

Build a deterministic code workflow that automatically verifies the email on every new lead row in Airtable and writes the result back to that same row. No branching, no AI reasoning, no summarization. Just trigger, verify, update, the same way every time.

Trigger: poll Airtable for new records using the new_record event type. The user will configure which base and which table to watch (a lead-intake or signup table). The workflow fires once per new record.

Step 1. From the new Airtable record, read the email address out of the source email field (default field name: Email).

Step 2. Call NeverBounce Verify Single Email with that email address. The response includes a deliverability result code (one of valid, invalid, disposable, catchall, unknown), a verified-at timestamp, and a flags array.

Step 3. Call Airtable Update Record on the same record ID and write exactly these three fields, leaving every other field untouched:

• Email Status: the NeverBounce result code as a string (valid, invalid, disposable, catchall, or unknown).

• Verified At: the verified-at timestamp from the NeverBounce response, written as an ISO 8601 datetime.

• Verification Flags: the flags array from NeverBounce, joined as a comma-separated string so it fits a single-line text column.

Expose these as workflow inputs so the user can wire the flow to their actual schema: the Airtable base ID, the table ID (or name), the source email field name, and the three result column names (Email Status, Verified At, Verification Flags). Default the column names to those exact strings.

Every column mapping is fixed and every step runs the same way every time. The point is to keep an Airtable lead base clean automatically so downstream views and follow-up automations can filter on deliverable addresses without anyone running manual cleanups.
