- Choose your Interest groups for your list, if any.
- Under Advanced, Choose if you would like users to confirm their subscription.
Please note that if a field is required in MailChimp, it MUST be mapped to a Ninja Forms field, no exceptions, or your contact will not be added to the list. Please check for this first before contacting support.
MailChimp Opt-in field
The MailChimp Opt-in field gives the user an option to choose if they want to be added to a MailChimp list without the need to setup a Conditional Logic statement.
If the MailChimp Opt-in field is checked, the MailChimp Action will be processed and the user will be added to the list. If the Opt-in is unchecked, the MailChimp Action will be ignored.
To add a MailChimp Opt-in field to your form, click on the blue add field button, then choose the MailChimp Opt-in
