📱 Some Common Bulk SMS Issues and How to Fix Them?
Sending Bulk SMS can be incredibly effective, but users may encounter issues that impact delivery, formatting, or campaign performance. Here are some of the most common problems and their solutions:
✅ 1. Low Delivery Rate
Cause: Invalid numbers, DND (Do Not Disturb) restrictions, or poor sender reputation.
Fix: Regularly clean your contact list, avoid spammy content, and use a registered sender ID with a reputed provider like Muzztech.
✅ 2. Message Not Displaying Properly
Cause: Special characters or incorrect language encoding (especially for Hindi or Unicode).
Fix: Use proper encoding and test the message format before bulk sending. Muzztech's dashboard includes a preview feature.
✅ 3. DLT Template Rejection
Cause: Improper message formatting or use of unapproved variables.
Fix: Follow the DLT guidelines strictly. Use approved headers and submit templates with fixed and variable parts clearly defined.
✅ 4. Duplicate Messages Being Sent
Cause: Resubmitting the same campaign multiple times or poor CRM integration.
Fix: Use a campaign ID tracking system and integrate with Muzztech CRM to avoid repeated triggers.
✅ 5. Delay in Delivery
Cause: Peak traffic hours, unverified sender ID, or template approval delays.
Fix: Schedule your campaigns during off-peak hours, pre-approve templates, and ensure sender ID registration is complete.
