Sending an RCS message and seeing it marked as “sent” does not always mean the customer received it. This is one of the most common points of confusion when businesses start checking RCS delivery. A message passes through several steps before it reaches the customer's phone, and problems can happen at different points. The useful approach is to separate sent, delivered, read, and failed states instead of treating them as the same thing. Google’s RCS for Business documentation provides delivery and read events so businesses can track what happened after a message was sent.

Start With the Message Status

The first thing to check is the status connected to the message ID. A business system should keep a record of when the message was submitted, which recipient it was sent to, and what status was later received. This helps answer a basic question: did the platform accept the message, or was there a problem before delivery? A message being accepted for processing should not automatically be treated as proof that the customer's device received it. For troubleshooting, keeping the original message ID is important because later delivery or read events are linked to that message.

Understand Delivered and Read Separately

RCS provides different events for delivery and reading. A DELIVERED event means the message was successfully delivered to the user's device, while a READ event indicates that the message was opened or acknowledged. This difference matters when a business is trying to understand poor response rates. If a message has a delivery event but no read event, the delivery system may be working while the customer simply has not opened or engaged with the message. If there is no delivery event, the business needs to investigate the delivery side before judging the content or customer response.

Check Your Webhook

RCS delivery and read events are normally sent to the business through a configured webhook. Google states that agents receive notifications for message delivery and read events through the webhook, which means a poorly configured or unavailable webhook can make it difficult for a business system to record what happened. This creates an important distinction: sometimes the message itself has a problem, while other times the message may have been delivered but the business did not correctly receive or process the event.

If your dashboard shows very few delivery updates, check whether the webhook is receiving requests, returning the expected response, and processing the event data correctly. Logs should also be reviewed around the time the problem occurred. Looking only at the campaign dashboard can hide an integration problem.

Check Whether the Customer Can Receive RCS

Not every phone number is automatically able to receive every RCS business message. Device capability, RCS availability, carrier support, and regional availability can affect whether a user can receive an RCS message. Google's RCS for Business documentation includes capability checks specifically for verifying whether a user's device is RCS-enabled and capable of receiving messages.

This is especially important when a business sees a sudden difference between two groups of customers. If one group receives messages normally while another group does not, checking device and network capabilities can help identify whether the issue is related to recipient support rather than the message itself. Businesses should avoid assuming that every phone number in their database has the same RCS capability.

Look at Delivery Events Instead of Only Campaign Numbers

A campaign dashboard may show totals, but individual delivery events are often more useful when investigating a problem. Google records DELIVERED and READ events against specific message IDs, and its reporting documentation also distinguishes delivery receipts from read receipts.

For example, suppose a business sends 10,000 messages and sees that 8,000 were delivered. The important question is not simply that 2,000 were missing. It is whether those failed deliveries came from particular carriers, regions, devices, message types, or sending periods. Breaking the data down can reveal a pattern that the overall number hides.

Check for Expired or Undelivered Messages

Some messages are time-sensitive. An OTP, fraud alert, appointment reminder, or delivery update may have little value if it reaches the customer hours later. RCS for Business supports message expiration using a time-to-live setting, and Google documents events for messages whose TTL has expired. Google also notes that message delivery is not guaranteed.

This is why businesses should not simply keep retrying an old message without considering its purpose. If a message is no longer useful, sending the same content later can create confusion. For time-sensitive communication, businesses may also need a fallback channel. Google specifically recommends an alternate channel such as SMS for important messages when RCS delivery is not successful.

Compare Delivery Problems With Read Problems

A useful troubleshooting process is to divide the issue into two parts. First, check whether the message reached the device. Second, check whether the customer opened it. These are different problems and require different solutions.

If delivery is low, investigate recipient capability, carrier availability, message expiration, sending errors, and the technical connection between your system and the RCS platform. If delivery is healthy but read rates are low, look at the message itself. The wording may be unclear, the timing may be poor, or customers may not understand why they received it.

This distinction can save businesses from making the wrong change. There is little value in rewriting a message when the real problem is that a portion of recipients cannot receive it. In the same way, changing technical settings will not solve low engagement if customers are receiving the message but choosing not to open it.

Keep a Record of What Happened

A reliable tracking setup should connect the customer's number, message ID, sending time, message type, delivery status, read status, and any error or expiration information available from the platform. This gives the technical team something concrete to investigate when a customer says, “I never received the message.”

It is also useful to test the same message on controlled test devices before a wider campaign. Google provides test-device tools and capability checks as part of its RCS for Business development process. Testing can help identify problems with message formatting, device support, actions, or integration before they affect a large audience.

Check the RCS Provider and Integration

If your business uses an external RCS platform, the provider may have its own dashboard, delivery reports, logs, or API responses. These records should be compared with the events received by your own system. A mismatch can help identify where information is being lost.

For businesses working with an RCS Messaging Service Provider, it is useful to ask for message-level delivery information rather than only receiving a campaign-level percentage. A useful report should help explain whether a message was sent, delivered, read, expired, or affected by an error. Google also maintains a partner directory for RCS for Business, including partners serving India.

Do Not Judge Delivery From One Campaign

One campaign is rarely enough to understand a delivery problem. Delivery can vary because of recipient devices, carrier conditions, message timing, message expiration, technical changes, or the type of communication being sent. Looking at several campaigns over time makes it easier to see whether the problem is temporary or part of a larger pattern.

For example, if delivery drops only during a particular period, the business should investigate what changed around that time. If the problem repeatedly affects the same group of users, capability or carrier differences may be more relevant. If delivery stays high but customers rarely read the messages, attention should move toward content, timing, and message frequency.

What Good RCS Delivery Tracking Should Tell You

The purpose of delivery tracking is not simply to produce a percentage. It should help answer practical questions: Did the message leave the business system? Was it accepted by the RCS platform? Was it delivered to the customer's device? Was it read? Did it expire? Was there an integration error? Could the recipient's device receive RCS?

Once these questions are separated, troubleshooting becomes much clearer. A business can then work on the actual problem instead of repeatedly changing things without knowing what caused the failure.

Good RCS delivery tracking is ultimately about understanding what happened to each message. When businesses connect message IDs with delivery and read events, check recipient capability, monitor webhook activity, and review expiration or error information, they can distinguish technical delivery problems from customer engagement problems. That makes it easier to fix the right issue and gives customers a more reliable communication experience.
