How do you optimize send delays for engagement?

Delay optimization improves engagement by reaching recipients at optimal moments:

Testing approach: Test different delays for the same automation. Split recipients randomly to receive email after 1 hour vs 4 hours vs 24 hours. Measure engagement and conversion by delay.

Analysis dimensions: Open rate by delay duration. Click rate and conversion by delay. Revenue per email by timing. Drop-off rates at different delays.

Factors affecting optimal delay: Urgency of the message (transactional = immediate). Consideration time needed (high-value purchases = longer). Competition timing (cart abandonment sweet spot). Recipient behavior patterns.

Send-time optimization: Use historical engagement data per recipient. Deliver within optimal engagement windows. Balance optimization with message timeliness.

The right message at the wrong time underperforms. Delay optimization ensures timing supports content.
