I want every new order on my site to trigger an immediate, well-formatted confirmation email. That message has to pull the customer’s order details and a concise summary straight from the database, then send it through our transactional mail service automatically—no manual steps, no delays. Here’s what I need delivered: • A reliable trigger tied only to the Order Placement event. • A responsive HTML email template that inserts the order items, totals, and billing / shipping information dynamically. • Seamless integration with our existing email gateway (SMTP, SendGrid, Mailgun or similar—happy to use whichever suits the current stack). • A simple configuration panel or file where I can tweak the subject line, sender name, and footer text without touching code. • End-to-end testing in a staging environment plus brief hand-off notes so my team can maintain it going forward. Success means every completed checkout immediately generates an email that lands in the customer’s inbox (not spam) and displays the correct order summary on all major email clients.
