One of the actions available on forms is the Email action. This will send out an email or emails. This can be to an administrator email or to an email address entered on the form.

In order to send the emails out an email provider needs to be configured. By default we provide a Sendgrid account that may be used for low volumes of emails.

There are several other email providers that may be set up and monitored for your application. They can be configred in the Project Settings.


You can use smtp for sending emails through Enter your smtp information to connect and send emails.


There are many situations where you need to validate a persons email address in realtime as they fill out the form, and fail the form submission if the email is invalid. A good example use case for this would be at an industry conference where you need to ensure that everyone who signs up at your booth provides a valid email address in order to win that amazing prize drawing. In order to provide this capability, has teamed up with an amazing email validation service called to provide realtime email validation to the forms.

Next, you will click on the New App button, and then provide your application a name and then Production. Note: You may want to use Sandbox to perform some tests to ensure it works. The sandbox allows you to use some predetermined email addresses that return certain results for you to test the application. You can find out more about how this works by visiting the Sandbox API documentation.
