Every time a Formstack response is submitted, Integromat will automatically validate the email address of that response. If the email status is "valid" it will create a new record in Airtable and send a Slack message. If the email status is not "valid" it will send a Slack message.
This is a predefined template that will make the creation of your scenario much easier. Of course, you can always expand and customize the scenario to meet your own individual needs.
