A transactional email confirms an action a person already took, such as a booking or purchase. It should arrive promptly, identify the business, and make the next step obvious.
Keep the message focused
- Put the event and relevant date near the top.
- Include only the details needed to verify or manage the transaction.
- Use a monitored reply address or a clear support route.
Test delivery, links, and rendering on common mail clients. Separate transactional messages from promotional campaigns so recipients can manage marketing preferences without losing important receipts.
