Email & Retention

Campaign

A one-time email or SMS blast sent to a segment on a specific date. The counterpart to a flow: deliberate, calendar-driven broadcasts rather than triggered automations.

A campaign is a one-time email or SMS send, dispatched to a specific segment on a specific day. Campaigns are calendar-driven (a product launch announcement, a BFCM sale, a Monday newsletter) — the counterpart to flows, which are behavior-triggered and run continuously in the background.

Healthy campaign cadence for ecommerce in 2026: 2-4 emails per week to engaged subscribers, 1 per week to unengaged. Undersending (1-2 per month) leaves revenue on the table; oversending (daily to everyone) destroys deliverability and list health.
