Marketplace Email Notifications

[Treezee]

I am the CEO of a marketplace where sellers can integrate with ShipStation. I want all of the "Order Shipped" & "Order Delivered" notifications to come from my website for consistency and to make my consumers trust me and not get confused. When a seller links my marketplace as one of their selling channels, I believe the ShipStation "Order Shipped" & "Order Delivered" notifications are default set to off, but the seller can edit these and turn them on. I would like to be able to have control over this for my entire marketplace. For every one of my sellers that integrates with ShipStation I would like to have them not be allowed to turn on these notifications. While they might think that turning on these notifications would be a positive thing, it would send the consumer duplicate emails which will lead to numerous chargebacks.
