A DLR, or delivery report, is a status confirmation that tells you what happened to an SMS after you sent it , whether it reached the recipient’s phone, failed, or is still in transit. It’s the receipt that closes the loop on a message, so you’re not left guessing.
How does DLR (Delivery Reporting) work?
When you send an SMS, it travels through the messaging platform to the mobile network’s SMSC (Short Message Service Center), which attempts delivery to the handset. As it moves, status updates flow back: the message might be reported as delivered, failed, expired, or rejected. The platform collects these and returns a delivery report against each message, often with a reason code explaining any failure. DLRs can be viewed in a dashboard or pushed to your systems via a webhook so your application knows the outcome in near real time.
How Onextel helps with DLR (Delivery Reporting)
Onextel provides delivery reports for messages sent through its platform, so businesses can see exactly which texts landed, which failed, and why. Reports are available on the dashboard and can be delivered to your own systems via webhook or API, letting you track deliverability in real time, spot problem numbers or routes, and trigger follow-up actions automatically.
Why it matters
Sending a message is only half the job , knowing it arrived is the other half. Delivery reports turn a blind send into a measurable one: you can prove OTPs and alerts reached customers, catch failing routes before they cost you, and clean bad numbers out of your lists. For anything time-sensitive, like a login code, that confirmation isn’t a nice-to-have , it’s essential.
