Definition
A transactional trigger is a defined event that fires an automated email. When the event occurs — a purchase, a cart abandonment, a signup, a download — the trigger sends a pre-built message automatically. Transactional triggers sit at the intersection of automation and behaviour: they respond to what a subscriber just did.
Transactional emails are consistently the highest-performing messages in a program. Because they are expected and relevant — the subscriber just acted — they enjoy open rates of 40-70% and click rates far above broadcast campaigns. They are also increasingly zero-click: confirmations and receipts deliver value inside the inbox without requiring a visit to the site.
Common Transactional Triggers
- Order and payment confirmations
- Shipping and delivery notifications
- Password resets and security alerts
- Abandoned cart and checkout reminders
- Welcome and onboarding sequences
- Account, subscription and billing events
Best Practices
- Send instantly — relevance decays within minutes for events.
- Keep them useful — status, tracking and next steps, not marketing fluff.
- Expect zero-click behaviour — many recipients get value without clicking.
- Include a single relevant next action — upsell or support, not noise.
