Automated Email Sending with Attachments via Gmail Alias

This n8n workflow automates sending complex emails through Gmail, utilizing an alias, with support for attachments retrieved from URLs. Starting with a webhook trigger, it processes optional attachments, constructs a MIME-compliant email with HTML content and multiple files, encodes it properly, and sends it via Gmail’s API. It includes validation for email fields, dynamic attachment handling, and customizable email content, making it ideal for automated notifications, marketing campaigns, or customer communication workflows. The process ensures robust handling of binary data and dynamic email content, streamlining mass or automated email dispatches with personalized attachments.
