Do you email each school to ask if they accept Interfolio

[LetterKing]

I provide the email address generated by Interfolio when schools' application system asks me to provide referee contact info. However, I am worried that the Interfolio letters may not be accepted by certain schools depending on the configuration of their application website, and they may not tell why my letters are missing. Do I need to email each school I applied for to double check if their system accepts Interfolio letter?
