Non-drop

Non-drop is a seller's label for a service whose delivered engagement is said to stay in place, describing expected supplier behaviour rather than a commitment the panel is bound by.

The label is written by whoever builds the catalogue, and in a resale chain that is often a panel copying the name from its own supplier's list. Nobody in the chain has to test it before publishing it. It reflects the supplier's account source at the time the name was written, and the name usually stays when the source changes.

No delivered engagement is fully safe from removal, because the platform, not the panel, decides which accounts survive. What non-drop can realistically describe is a service where drops are expected to be small or slow. Whether you get anything back if that expectation fails depends entirely on what the service description says about refill.

That is the trap. Some non-drop services carry no refill at all, on the reasoning that a service that does not drop should not need one. If the count falls, the label gave you nothing to claim against. A service marked non-drop with a stated refill window is a stronger offer than one marked non-drop alone, and a plain service with a clear refill window can be stronger than both.

What it does not mean

Non-drop does not mean zero drops, and it does not mean a refill is included. It is not a warranty term. Unless the service terms attach a window, a trigger and a scope, the word describes the seller's expectation and commits the panel to nothing you can enforce.
