Why triggers beat scheduled sends

A broadcast campaign goes to every subscriber at the same time, regardless of whether they are
thinking about a purchase. A triggered message arrives when the person has already shown intent:
viewed an item three times, added to cart and did not buy. That is the source of the click-through
difference — triggered emails are typically clicked two to five times more often than broadcasts.

The mechanism is simple: the shopper leaves a signal, the system catches it, the communication
arrives at the right moment.

Standard triggered scenarios in e-commerce

Trigger Event Action
Abandoned cart add_to_cart with no purchase within N hours Email or push with the cart contents
Price drop A wishlisted item gets cheaper Push notification about the discount
Return after a pause A visit after 30+ days away Email with what is new plus personal recommendations
Post-purchase purchase Email asking for a review plus accessory recommendations
Loyalty threshold Cumulative order value reaches a tier Notification of the new tier

Building a system that does not annoy

The main risk in trigger marketing is aggressive frequency. If someone receives three abandoned-cart
reminders in a day, they will not leave another cart — because they will not come back.

The rules of a sane system: no more than one reminder per occasion per 24 hours, a global cap on
automated communications (three a week, for instance), and a separate opt-out per notification type.

Tip: test the trigger delay. For an abandoned cart, the best send window is usually one to
three hours after the event — not instantly and not a day later.
