You can directly add a PDF file link in the email content, or dynamically insert the link using a variable so that the customer can click to download or view the invoice. May I ask what issue you encountered during this process?

A common concern we’ve encountered is that many businesses are hesitant to click links in emails due to security protocols. As a result, they have requested that we send PDF attachments directly. We believe this is a valid request that aligns with standard security practices.
