Common Delivery Issues

Why Aren't My Messages Delivering?

Here are the most common delivery issues and how to resolve them.

1. Messages Stuck in "PENDING"

• Cause: Carrier network congestion or recipient phone is off
• Fix: Wait up to 48 hours. The carrier will retry delivery automatically.

2. High Failure Rate

• Cause: Outdated contact list with many invalid numbers
• Fix: Clean your contact list. Remove numbers that consistently fail.

3. Messages Flagged as Spam

• Cause: Sending identical messages to large groups without personalization
• Fix: Use merge variables like {name}. Avoid ALL CAPS and excessive punctuation.

4. Sender ID Not Showing

• Cause: Sender ID not approved on all networks, or using numeric fallback
• Fix: Check your sender ID status in Settings. Some networks take 3-5 days to approve.

5. International SMS Not Delivering

• Cause: International routing not enabled or incorrect number format
• Fix: Ensure numbers include country code (e.g., 254 for Kenya). International SMS costs 80 TZS/msg.
