Filter Gmail messages from specified sender into New Gmail Label

Hi @Davyn 

Good question.

Are you trying to Label existing emails in Gmail?

To clarify, Zaps work while ON for new data going forward.

No, just new incoming and outgoing emails to the specified email address needs the label applied.

Would using a Gmail Filter rule suite your use case?

Yes but I want to automate this in Zapier, if possible.

I have explored the add label to email but can’t get it to work where it labels emails from a specified email address…. I can only label the email message itself, based on searching for the subject of the email in a zap.

Is there a way to build the zap (or custom development) in order for me to automate assigning a filter to the specified email which then adds the incoming/outgoing emails to the new label that was created? 

Here are some screen shots of the zap to trigger after new smartsheet row is added. 

I am getting that error at the end of the zap. Everything else works, but can’t add the email to the new label.

And that still doesn’t achieve the desired result of creating the filter for the email address so it saves under the new label.
