Definition
Email automation types are the distinct categories of triggered email sequences, each serving a different purpose and triggered by different subscriber actions or lifecycle events. Understanding automation types helps you design a complete automation programme that covers every stage of the subscriber relationship.

Frequently Asked Questions
Most programmes should have 5-10 active automation types. Start with the four highest-priority types (welcome, abandoned cart, post-purchase, re-engagement) and add more as capacity allows.
Welcome automation is the most important because it establishes the subscriber relationship. Abandoned cart generates the highest immediate revenue. Both should be prioritised.
Subscribers can be in multiple automations simultaneously. A subscriber who receives a welcome sequence and then abandons a cart should enter the abandoned cart sequence while still in the welcome sequence. Ensure automations do not conflict.
Track goal-specific metrics for each type: welcome = conversion rate, abandoned cart = recovery rate, post-purchase = repeat purchase rate, re-engagement = reactivation rate.
Browse abandonment and milestone automations are the most commonly missing types. Browse abandonment captures interest that falls short of cart. Milestone automations build long-term loyalty.
