Hi @Deathbymonkeys,
How do you want to filter the received emails by the peoject number to a Trello board or a Teams channel?
Do you want to create a card in Trello using the Project number as a dynamic content value of the Board Id field and post a message using the same Project number as a dynamic content value of the Channel Id field?
Could you please share a bit more about your scenario?
If you could provide more details about your scenario, we would provide a proper workaround for you.
Best regards,
Kris
