Which method can the support team use for automatic follow-ups on specific keywords in case subjects?

The most suitable method for automatic follow-ups on specific keywords in case subjects is the auto-response rule. This feature allows organizations to create automated responses to incoming cases, enabling them to tailor their communication based on keywords identified in the case subject line.

Auto-response rules can be configured to trigger based on specific criteria, such as keywords indicating urgency or specific topics. When a case is received, if it contains designated keywords, the auto-response rule activates and sends an automatic email to the customer regarding their case submission. This ensures timely acknowledgment and can improve customer satisfaction by providing immediate feedback.

The other options, such as email-to-case, validation rule, and support settings, do not provide the same targeted automatic responses. Email-to-case pertains to the creation of cases from incoming emails but does not handle follow-ups based on keyword recognition. Validation rules are utilized to enforce data integrity rather than facilitate automatic communications. Support settings offer general configurations for managing support processes but lack the specific functionality needed for keyword-triggered responses. Therefore, the auto-response rule is the correct method for this specific purpose.
