Shopify (Dropship Automatic Email Notification Orders)

Description

Hello,
We sell via Shopify, and some of the products are dropshipped by a range of vendors.We want to set up automatic emails going to those vendors on a product-by-product basis, notifying them to ship the orders. Please can someone support with setting this up? I'm not sure if the functionality is directly in Shopify, via Shopify automation or flow, or a third party app.
The notifications must go on a product basis (rather than vendor), and would ideally then be excluded from packing slips.
