Keyword Responses Incomplete

Learn how to resolve TCR Error Code 611. Fix "Keyword Responses Incomplete" by updating your START, HELP, and STOP messages to meet A2P 10DLC

Why This Rejection Happens

The carrier vetting team found that your automated responses to mandatory keywords (STOP, HELP, UNSTOP) are either missing, incomplete, or non-compliant. Every 10DLC campaign must have autoreplies configured for these specific keywords.

  • Missing Brand Name in the HELP or STOP response.
  • HELP message does not provide a support email or phone number.
  • STOP message does not confirm that the user has been unsubscribed.
  • Placeholder text left in the template (e.g., "[Insert Brand]").

Root Cause Analysis

Primary Triggers

  • The "Silent" HELP: Users text "HELP" and receive no response, or a generic system error. Carriers test this live.
  • Missing Contact Info: The HELP response says "Contact us for help" but gives no email or phone number to actually do so.
