Add people to your campaign by creating a new form or by hooking up an existing one.
Create a new Form from a Campaign:
Click Opt-in Forms
Click Create a Form
Give your form a name
Click Create Form
When a form is created from inside of a campaign, a new form rule is configured to send the campaign to any person who submits the form.
If you already have a form connected to your campaign via an integration, leave this blank.
Customize the form’s design from the Design tab.
