Limit Form to domain by validating email address

You can't get this natively with Airtable's forms. However, you can get this with 3rd-party apps.

For example, this is a built-in feature of Fillout’s advanced forms for Airtable.

Fillout offers hundreds of features that Airtable’s native forms don’t offer, including the ability to verify email addresses in a number of different ways, including sending an email verification code to the user. However, they have other ways of validating email addresses as well, such as automatically "pinging" the email address to ensure that it is valid.

Fillout also offers hundreds of advanced form features that Airtable doesn't natively offer, including the ability to update Airtable records from a form, display Airtable lookup fields & Airtable rollup fields & Airtable attachments & formulas on forms, dynamically & conditionally filter linked record fields by any values that you would like, perform math or other live calculations on your forms, accept payments on forms, create multi-page forms with conditional paths, create new linked records on a form, display as many fields as you want to see in a linked record selection list (including attachments), connect a single form to dozens of external apps simultaneously, limit the number of linked records that can be chosen, set advanced field validations & limitations, upload an unlimited amount of attachments simultaneously, add CAPTCHAs to your form, add choice matrixes to your forms, direct integration with hundreds of apps like Calendly & Google Maps on your forms, and so much more.
