Delivered, failed, pending
The statuses that matter: the operator has delivered the message to the handset, has failed it, or has not reported back yet.

Real delivery reports from the operators
Know what happened to every message. ZafeConnect passes on the delivery reports (DLRs) returned by the mobile operators themselves, not estimates.
What matters
What matters for delivery reports
A delivery report, or DLR, is the operator’s confirmation of what happened to a message: delivered, failed, or still pending. Without real DLRs you only know that a message left your system, not that it reached your customer.
A report is not a read receipt
A DLR tells you about delivery to the phone, not whether the recipient read the message. Opens and clicks come from channels and links that can measure them.
Detail varies by destination
Some operators return rich status and error codes, others only a basic status, and a few return very little. A good provider tells you what to expect per country.
Timing differs by network
Some networks report back quickly, others later. Build your logic to wait for the report rather than assume.

FAQ
Delivery reports: frequently asked questions
What is a DLR?
A delivery report, also called a delivery receipt, is the status that the mobile operator returns for a message, for example delivered or failed.
Are delivery reports always available?
Operators decide what they return. In some countries reporting is limited or delayed. Ask us about the destinations you send to.
How do I receive delivery reports?
Poll the message status endpoint, or receive webhook events. The API documentation lists the fields and shows how to verify the signature.
Does a delivered status mean the customer read the message?
No. Delivered means the message reached the phone. Read status is only available on channels that support it.
