Adding attachments to WooCommerce emails is a highly valuable feature, as the standard WooCommerce setup does not include an option to attach files out of the box.
This functionality is essential for e-commerce sites needing to send items like:
PDF Invoices/Receipts (The most common use)
Product Manuals/Guides (For digital or complex physical products)
Warranty Certificates or Terms & Conditions
Digital Products/Downloads (As a backup to the main download link)
To achieve this, you need a dedicated WordPress plugin.
The best way to handle WooCommerce email attachments is generally through one of these plugin types:
These plugins focus specifically on attaching files to various WooCommerce emails.
Example: Email Attachments (from WooCommerce Marketplace/InoPlugs) or similar plugins like WooCommerce Email Attachments (by PluginsForWP).
Core Features:
Select by Email Type: Choose which files attach to specific emails (e.g., attach the PDF invoice to the Customer Completed Order email, but the T&Cs to the Customer Processing Order email).
WPML Compatibility: Supports attaching different files based on the customer's language.
CC/BCC Functionality: Add extra recipients to the transactional emails.
These plugins let you associate files with the product or order itself, which are then included in the email.
Example: Product Attachment for WooCommerce (Dotstore) or WooCommerce Product Attachments (WooCommerce Marketplace).
Core Features:
Product-Specific Files: Attach a unique manual or guide for a specific product or product category.
Order Status Control: Only make the attachment visible/downloadable once the order reaches a specific status (e.g., Completed).
Download Expiry: Set an auto-expiry date for the download link for security.
Many feature-rich email builders or automation plugins include attachment capabilities as a premium feature.
Example: YayMail Premium or FunnelKit Automations.
Core Features: You get the attachment feature alongside a full visual, drag-and-drop editor to completely customize the look and feel of your emails.
When choosing a plugin, verify it has these features:
Multiple Attachment Support: Ability to attach more than one file (e.g., an invoice and a warranty card).
File Type Flexibility: Supports common file types like PDF, DOCX, ZIP, JPG, etc.
Order Status Triggering: The ability to send an attachment only when an order status changes (e.g., attach the download link only when the status changes to "Completed").
Would you like to focus on attaching a generic PDF invoice to all orders, or do you need to attach product-specific files?
