Hello! I am trying to look into workarounds for sending emails from transactions (invoices) to multiple recipients instead of only the primary email address on the customer record. Please let me know of any insight into this, thank you!

we have a custom field on the invoice with a comma separated list of email addresses in it (imported from another system) Our workflow picks up this field and uses it in the "cc" field of the email. As long as the primary contact should be receiving the emails, this works fine for us and is a super-easy workflow to put in
