GMAIL - GOOGLE CONTACT LIST

Hello,

We are currently testing the paid Zapier account for the multi-zap ability, but before we proceed with purchasing, we need to figure out how to send an email (from Gmail) to our pre-set contact list in Google Contacts. Is this possible?

Goal: customer purchases a zoom class using WooCommerce. Wordpress automatically sends the live zoom class link. Once the class is done (and recorded) the recording link gets sent to only those that purchased it​​​​ (there are multiple options - with recording or class only)

• we have successfully set up zap #1
  • Order in WooCommerce: new order trigger, continue filter if meta contains the word the word “recording” 
  • Find or Create Contact in Google Contacts
  • Add Contact to Group in Google Contacts (label “may 6”)
• we need a second zap 
  • New Recording in Zoom
  • Only continue if… topic = May 6
  • Send Email in Gmail
    • I’m trying to extract all of the contacts labeled “may 6” from the first zap but “The value in the "Bcc" field is invalid.”

I can’t find any solution on how to send the email to the group - any advice appreciated!

Thank you!
