I am attempting to work on a module that will send an email to several different dropshippers when an order is placed. I am not getting errors after a few tweeks. although. i'm not receiving any emails no matter what i order. Below are the guideline for the module.

Mind you that i'm the type of person that will open his inward swinging bedroom door, halfway open i forget im opening it and walk right into it. please if you can help dumb it down.

  1. When a product is ordered, send an email to multiple dropshippers individually.
  2. During the ordering process, each order has the potential to include multiple products from various dropshippers.
  3. Each dropshipper will exclusively receive an email containing only the products assigned to them.
  4. The products of the dropshippers will be identified through the Magento Attribute Set.
  5. The dropshippers' email addresses will be identified using the same Magento Attribute Set as mentioned in step 4.
  6. The email that is being sent must include the customer's name, shipping address, ordered products, quantity, and order ID.
  7. The email subject is the order ID

This is the code im working with.

Check email sending code.

Replace below code

// Send email
$transport = $this->transportBuilder
        'area' => \Magento\Framework\App\Area::AREA_FRONTEND,
        'store' => \Magento\Store\Model\Store::DEFAULT_STORE_ID,
