Why Are Bulk SMS Messages Promo OTP Not Delivering?

5-Point Checklist Before Sending Bulk SMS on Multitexter

1. Register and Verify Your Sender ID

Before sending promotional SMS or transactional OTPs, make sure your company, business, or brand name is registered as a sender ID on BulkSMSLive. This allows your SMS to appear with your approved business name instead of a random number, improving trust and delivery.

2. Prepare the Right Business Documents

A registered company or brand should have the necessary documents ready for sender ID approval. These may include business registration details, company name, brand name, contact information, and authorization to use the sender ID.

3. Choose the Right Message Type

Decide whether you are sending promotional SMS or transactional OTPs. Promotional messages are used for marketing, offers, and announcements, while transactional OTPs are used for verification, login, payment alerts, and security notifications.

4. Clean and Format Your Contact List

Ensure your phone numbers are valid, active, and correctly formatted before uploading them to BulkSMSLive. Remove duplicates, inactive numbers, and incorrect entries to improve delivery performance and reduce wasted SMS units.

5. Test Delivery Before a Full Campaign API & on Platform 

Before sending to a large audience, run a small test campaign. Check if the sender ID displays correctly, the message delivers quickly, and the content appears exactly as intended. This helps you avoid errors before launching the full bulk SMS campaign.
