The effect of SMS cannot be reduced to one universal open rate. A standard SMS does not provide a reliable measure of whether it was opened, and the outcome depends on purpose, audience and execution.
Choose the objective before sending
A reminder might be assessed through fewer missed appointments, an operational update through reduced uncertainty and a campaign through relevant visits or actions. The objective determines which data you need.
Separate the signals
An accepted request, delivery status, link click and completed action describe different stages. None should be interpreted on its own as proof that the recipient read, understood or valued the message.
Compare fairly
Use the same definitions and comparable audiences when evaluating campaigns. Consider complaints, opt-outs and cost as well, and document changes in timing, content and segmentation.
Establish a baseline
Understand the process before introducing SMS. How many appointments are missed, how much time does support spend, or how many people complete the action? A simple baseline makes it easier to see whether the change genuinely helps without attributing every simultaneous development to SMS.
Report what the data actually shows
Describe definitions, period and limitations alongside the results. Say “recorded clicks” when that is what was measured, not “interested customers”. A restrained report supports better decisions and makes later campaigns easier to compare on the same basis.
A relevant next step
Make the next campaign more relevant
Plan recipients, wording, timing and follow-up as one coherent journey.
