Editing Double opt in vs. single opt in (section)

=== Configuration options and settings ===
When setting up your forms, you have the choice between these configuration options:
- '''Double opt-in''': This option requires subscribers to confirm their email address via a confirmation link sent to their inbox.
- '''Single opt-in''': Contacts are automatically marked as '''Active''' and can start receiving messages right away after submitting their information.

Be mindful that '''double opt-in''' is not available for SMS marketing list forms; this method is exclusive to email marketing lists.
