Hello,
I am trying to automate my email workflow. My trigger is just getting a new email in my inbox and after a few checks, I want to add a particular label to that email. Which option here do I select to add a label to the email?

Hey there 
When using the custom value option to select a value from a dropdown menu field such as that Message to be Labeled field, you’ll usually want to select the ID for the item you wish to select. You can learn more about that here: Add custom values to dropdown menu fields in Zaps
And looking at the fields available with the New Email Gmail trigger it appears that the ID field would be the one you’d need to select, for example: 
Can you try selecting the ID field from the Gmail trigger in the Zap and let us know if that works?
