Delivery Receipt (DLR) is a status notification sent by a mobile carrier or messaging gateway to confirm that an SMS message has been successfully delivered to the recipient's device. It provides real-time confirmation of message delivery and is an essential feature for businesses using SMS for communication, marketing, or SMS alerts. DLRs are typically used to ensure accountability, measure delivery success, and improve message tracking.

Delivery Receipts typically include:

• The SMS delivery status (e.g., delivered, failed, pending)
• Timestamp of delivery or failure
• Carrier response or reason for delivery failure (if applicable)
• Message metadata for reporting and analytics

• Support for real-time updates within online messaging platforms or SMS APIs

   

Why Delivery Receipts are Important?

Delivery Receipts are important because they provide transparency and accountability in SMS communications. Businesses rely on DLRs to confirm that messages are reaching their intended recipients, allowing for better tracking, reporting, and performance analysis. They also help identify issues with message delivery, such as invalid numbers or carrier blocks, enabling timely troubleshooting. Ultimately, DLRs ensure reliability and help maintain the integrity of SMS campaigns or notifications.
