Attachments, CC, BCC and Reply‑To
Recipients
Section titled “Recipients”In the Send email action you can set To, CC, BCC and Reply‑To. Each field accepts fixed addresses or Liquid variables, for example the customer’s email.
Attachments
Section titled “Attachments”Attach a file to every email, or use a file URL from a variable (for example an invoice link stored in an order metafield) so each email carries the right document. This is how merchants send B2B invoices automatically: see the B2B invoice recipe.
