How do I validate email addresses in Airtable?

Filla's Email Validator connects to your Airtable base and checks email addresses across your entire table. Create an Email Validator tool in your Filla workspace, select the table and the email field to validate, and choose an output field for validation results. Run the tool and Filla checks each address with four validation layers: syntax format, MX record lookup, disposable provider detection, and typo detection. Results are previewed before writing, so you can review flagged addresses and confirm. The validation status is written to your Airtable records, where you can filter for invalid, disposable, or typo-flagged addresses and clean them up.

What does MX record validation check?

MX record validation performs a DNS lookup on the domain portion of each email address (the part after the @ symbol). MX records tell the internet which mail servers handle email for a domain. If a domain has no MX records, it cannot receive email, which means any address at that domain is effectively invalid. This check catches typos in domain names (like gamil.com instead of gmail.com), domains that have been shut down, and completely fabricated domains. MX validation goes beyond simple format checking because an address can be syntactically perfect but still undeliverable if the domain does not exist.

Can Filla detect disposable email addresses?

Yes. Filla checks each email address against a regularly updated database of known disposable email providers. Disposable email services like Mailinator, Guerrillamail, Tempmail, 10minutemail, and hundreds of others provide temporary addresses that expire after a short period. These addresses are commonly used to bypass signup forms, trials, and gated content. Filla flags any address from a known disposable provider so you can exclude them from your email sends, remove them from your contact list, or require a permanent address instead.

How do I clean my email list in Airtable before sending?

Run Filla's Email Validator on your email field before sending any bulk email campaign. The validator checks every address for format errors, domain validity, disposable providers, and common typos. After the scan, filter your Airtable view to show only records with valid email addresses and use that filtered view as the audience for your Bulk Email Sender. This two-step workflow (validate then send) reduces bounce rates, protects your sender reputation, and ensures emails reach real inboxes. Filla's Email Validator and Bulk Email Sender are designed to work together as a complete email operations pipeline within your Airtable base.
