Gravity Forms Email Users lets you send tailored emails, to one user or many, to people who filled out a form that contains an email field. It pulls email addresses from a form’s entries and gives you an interface to build and send a mass email. Emails are sent using core WordPress functionality.

Use merge tags in the sender, recipient, subject and message body fields to personalize each email from the entry. Filter recipients with conditional logic based on the values in their submission. Write the message in a rich text editor, preview the exact email each recipient will get and save drafts to finish later.

Use it to inform previous participants of a new event.
