An email auto-response is defined as a trigger campaign email sent in response to a specific action. This means that the email is automatically generated and sent to the recipient based on predefined conditions being met, such as filling out a form, signing up for a newsletter, or making an inquiry.

The primary characteristic of an auto-response is its immediate reaction to user behavior, providing timely communication tailored to the action taken. This approach enhances engagement and ensures that the recipient receives relevant information promptly, making it an essential aspect of nurturing leads and maintaining customer relationships.

The other options do not accurately describe the nature of an auto-response. For instance, a batch-campaign email scheduled nightly is not triggered by a specific action but rather sent out based on a set schedule. Advanced filter logic relates to segmentation and targeting within campaigns, rather than the immediate nature of an auto-response. Lastly, a sales alert email is typically a notification intended for internal stakeholders rather than a response sent to customers or leads based on their actions. This reinforces why the first option precisely encapsulates what constitutes an email auto-response.
