Hello ​@Arthur M , Klaviyo does not support multiple CC or BCC recipients in flows. Each email is sent individually. You can work around this by setting up email forwarding in your provider, using Zapier or an API to send emails via an SMTP service, or using a shared email address like team@example.com to keep everyone in the loop. Let me know if you need help setting this up.

​@Arthur M, 

Following on what ​@MANSIR2094 mentioned, if your are using Google Workspace for example, we use Google Groups to do catchall BCC (or CC) when we are testing initial Flows.  You can create a Google Group with an email address that allows it to receive external emails so everyone internally can get a daily summary or (each email).  You can find the instructions to setting this up here:

• Google Workspace: Create a group in your organization

Hope that helps!
