Messages will be sent out gradually until an unspecified threshold is reached
Once reached, the subsequent messages using this template will be held to allow enough time for customer feedback

This affects new, recently unpaused marketing template messages or templates of low quality.

You will also see the template quality status when creating it in Campaigns and Studios:
