Try a sign-up flow demo

This working demo has an email OTP, custom logic to qualify users and payment fields.

✉️ Email details

This first step verifies if the email domain has a valid MX record, if it's valid, it checks if it's a free email provider (eg. @gmail.com) or a company domain. If the user provides a free email provider, it continues to a second step to ask for an email OTP verification flow, otherwise, it jumps to the last step.

Try this form using a non existing email domain, a free email provider (eg. @gmail.com) or a company email domain.
