Editing Subscribe by email opt in method (section)

=== Introduction ===
The '''Subscribe by email opt-in method''' is a feature in ActiveCampaign that allows subscribers to opt into your email marketing list by sending an email to a designated ActiveCampaign-generated email address. This method offers a simple and convenient way for users to express their interest in your content without having to go through a more traditional sign-up process. Understanding this feature is crucial for marketers looking to streamline their subscription process and engage with their audience effectively.

This feature supports a single opt-in process, meaning that subscribers who opt-in via this method do not receive a confirmation message before being added to your email list. Their contact record is created immediately upon email receipt, enhancing the speed and efficiency of your enrollment process.
