Boundary
A silent or imagined reader is not evidence of uptake, access success or agreement.
Complete source

Invitation
Write an honest feedback record and a possible invitation.
Next try
Use one actual consensual question if available, then distinguish that reply from your own design choice.
Ordinary possible response
No feedback was supplied. I could ask a willing reader what they understand about my source.
