Short answer
For most Sendblue messaging use cases, CNAM registration is not the main setup step you need to worry about.
What CNAM is
CNAM is a caller-ID naming concept that matters more in voice/telephony contexts than in the core Sendblue messaging flow.
What this means practically
If you are focused on Sendblue messaging workflows, CNAM is usually not the first thing to troubleshoot.
If you have a specific calling/display-name use case, treat that as a voice/caller-ID question rather than a general messaging setup question.
