Does time of day matter for triggered emails?

Myth: Triggered emails should just send when triggered.

Reality: Optimal timing depends on email type and purpose.

When immediate matters: Transactional: Password resets, confirmations, alerts. Time-sensitive: Flash sale notifications, event reminders. Completion support: Cart abandonment within the decision window.

When optimization helps: Marketing automation: Welcome series, nurture sequences. Re-engagement: Win-back campaigns. Educational content: Drip sequences.

Optimization approaches: Send-time optimization using engagement history. Time-zone-aware delivery for appropriate local times. Day-of-week consideration for business content.

Balance timeliness and optimization: Fresh triggers lose relevance if held too long. Optimization that delays days defeats the purpose. Most STO targets hours, not days.

The right time depends on the right email. Not all triggers have the same timing needs.
