Hello! I currently have a Zap set up that sends the contact name and email to a Google sheet every time I send an email. How do I set it up to not add contacts that are already in the sheet? Any help is greatly appreciated!

Hi ​@AprilJones 

Use this Zap action: GSheets - Lookup Row

Check the checkbox at the bottom of the Zap step config to create row if not found.
