Airtable phone and email validation

Why validate inside Airtable

Airtable bases double as CRMs for a lot of small teams, and their phone and email columns are never validated. An Automation with a Run script action can call LookupLab when a record is created and fill in line type and email status in the same base.

The script is about fifteen lines and reusable across bases.

Setup

1. Create fields: Line type, Carrier, Email valid.
2. Add an Automation: When record created, Run script.
3. In the script, fetch https://lookuplab.io/api/v1/phone/?number=... with the Authorization header and update the record with the response.
4. Repeat for email.

Phone validation is not consent, ownership verification or guaranteed delivery. Email syntax and MX checks establish domain-level signals, not proof that a particular mailbox exists.

What teams build with it

• Lightweight CRM hygiene.
• Event registration lists checked before SMS reminders.
• Vendor and supplier contact validation.
