The problem starts when the drop looks something like this:this

The drop in the image above means event discard. In simple terms, Omnisend refuses to use Rush events. Rush is constantly monitoring its services, so when something like this happens, the customer support team at Rush will contact you. Currently, there is no other way to verify if Omnisend is refusing Rush events clearly on the Omninsed UI.

Root cause

Omnisend API applies a strict property type policy on their data. So, if a property is auto-matched incorrectly to a different type, the events will be discarded when the property later is matched correctly. The highlighted property in the image below should be marked string not integer.
