Deleted Magento Products Still Show up in a third-party app

[Anonymous]

I am trying to delete products from magento but they are still in the third-party app we are passing data to when we query it.

So, deleted items in Magento are still showing up int the email marketing app, that shouldnt.
need to figure out if they do still exist in magento.
 Has anyone experienced a similar issue?
Is there anything I need to know about Magento's  inventory management system that they’re using?
