How to run it
Set up properly
Be clear on the messages you are testing, the glossaryChannelA channel is a source or pathway through which users arrive at a product, such as search, social media, paid ads, or direct traffic.Open glossary term and moment they appear in, and what you need somebody to do as a result.
Prepare realistic scenarios. A message read while expecting it behaves nothing like the same message arriving unannounced during a task.
Run the method
Message testing is contextual and interactive. You are testing whether something is noticed, understood and acted on: three separate failures wearing one label.
- Present the message in its real glossaryInterfaceAn interface is the point of interaction between a user and a system, where inputs are made and outputs are received. It can be visual, physical, or conversational.Open glossary term or glossaryChannelA channel is a source or pathway through which users arrive at a product, such as search, social media, paid ads, or direct traffic.Open glossary term, with its real timing.
- Observe reaction and understanding, including whether it was noticed at all. Unread is the most common failure and the least reported.
- Ask follow-up questions on glossaryClarityClarity is how easily users can understand what is happening and what they need to do.Open glossary term and tone once the moment has passed.
- Test variations in wording, timing and presentation separately, or you will not know which change worked.
- Record actions, hesitations and errors. What someone does after the message is the only reliable measure of whether it worked.
Focus on whether people understand and act as intended. A message that is clear, well-toned and ignored has failed completely.
Capture and make sense of it
The value comes from actionable glossaryInsightAn insight is a meaningful understanding that explains why something is happening and what it means.Open glossary term. After testing, document:
- Messages that confused, were ignored, or were misread
- Improvements prioritised by the cost of the message failing
