Editing Subscribe by email opt in method (section)

=== Configuration options and settings ===
The key configuration options for the '''Subscribe by email opt-in method''' include:

* '''Email address''': This is the unique ActiveCampaign-generated email address that contacts will send their opt-in requests to.
* '''Used in Lists''': Allows you to customize which email marketing lists contacts will subscribe to based on the email keyword used during submission.
* '''Action''': Select whether to '''Subscribe''' or '''Unsubscribe''' contacts based on the email actions.
* '''Use Filter''': This optional function determines which list a contact is added to by filtering through specific keywords.

### Important Notes:
- Each ActiveCampaign account utilizes a single, unique email address for the '''Subscribe by email opt-in method'''.
- The method treats contacts as '''Active''' upon email receipt without requiring any confirmation.
- Only the email address from which the opt-in request originates is recorded; no additional data such as names or custom fields will be captured.
