What Is a Trigger? The Event Behind an Offer

What Can Set Off a Trigger

Pretty much anything a store can track can act as a trigger. Most land in one of four groups:

Actions. A shopper adds to cart, views a third product or starts checkout.
Time. 20 seconds on a page, or an hour after a cart is left.
Values. The cart passes $50, or holds three or more items.
Exit signals. The mouse heads for the close button. That one gets its own name: exit intent.

The trigger is just the "when." Whatever shows up next is the response, like a popup, an email, a free shipping bar or a discount. Don't confuse it with a trigger rule, though. The trigger is the event itself, while the rule decides which events count and what happens next.

Same Message, Two Different Triggers

Example: A tea shop gets 1,000 sessions a day. It wants to remind shoppers about free shipping.

Trigger 1: 10 seconds on any page. It fires for nearly everyone who sticks around a moment, even people who haven't looked at a tea yet.
Trigger 2: 30 seconds on the cart page without starting checkout. In our data from 958 Shopify stores, about 8 of every 100 sessions reach the cart. At that rate, this fires for 80 sessions a day at most (1,000 × 8 ÷ 100).

Same message, very different crowd. The second group's smaller, but everyone in it has a cart and a reason to care about shipping.

Where Triggers Live on Shopify

Shopify Flow, Shopify's automation tool, starts every workflow with a trigger, such as an order being created. Email tools, including Shopify's own, can send a message when someone leaves checkout unpaid. For when to send it, see our guide to abandoned cart email timing.

Our app, Growth Suite, holds back its offers until it sees engagement signals, like time on page and cart activity. Then it shows them only to visitors less likely to buy. Its post-purchase upsell funnels can fire by product, order value or item count. For signals beyond a last-second popup, see our guide to behavioral triggers for cart abandonment.

A Trigger Sees What Happened, Not Why

People often treat a trigger as a read on intent, but all it knows is that something happened. An add to cart can mean "buying now" or "saving it for later."

That matters when the response is a discount. If a code fires on every add to cart, dedicated buyers get it too. So you end up giving away margin on sales you'd have made anyway.
