We've found that several emails (mostly from various subscribed newsletters) are not triggering change notifications to our specified endpoint. The subscription (to me/messages) is still active and the we receive notifications when sending directly to the inbox using both internal/external email addresses.

Is there a reason why certain messages will trigger a Webhook and others will?
