5 Behavioural Triggers Every Ecommerce Brand Should Have Running

Sending emails on a schedule is email marketing. Sending emails based on what a customer actually did is lifecycle marketing. The difference between the two is the difference between a brand that shows up on a calendar and one that shows up at the right moment.

Why behaviour beats the calendar

A calendar send reaches everyone at the same time with the same message, regardless of what they have done. A behavioural trigger does the opposite: it responds to a specific action – a purchase, a product view, a period of silence – and arrives precisely when that action makes the message relevant. These five triggers do not replace your campaigns. They run underneath them, quietly, catching the moments a monthly calendar can never anticipate.

The right email at the right moment is not interruption. It is service.
– The Antimony position

By the numbers: the five triggers and their windows

• ~24 hours – post-purchase onboarding: set expectations, deepen confidence, plant the seed for the second purchase before the first arrives.
• While interest is warm – browse abandonment: the softest touch in the lifecycle, and often the most effective for exactly that reason.
• One week before they run out – repurchase reminder: for consumables, timing is the entire strategy. A week late and they have bought elsewhere.
• 7–14 days after delivery – post-review request: sentiment at its peak; writing a positive review also deepens the customer's own commitment.
• 60–90 days of silence – win-back: a re-introduction of what has changed, not a bribe to return.

Triggers work while your campaigns run

None of this replaces the campaign calendar. Triggers run in parallel, catching individual moments the calendar cannot. It is the difference between a brand that sends four emails a month and hopes they land, and one that is present at exactly the right moment for each customer. Build the triggers first; let campaigns run on top.

In practice: Ka Ka Wa

Ka Ka Wa sells ceremonial cacao – a consumable with a genuine rhythm to it, which makes it close to the ideal case for behavioural triggers. Someone who buys a 250g bar has a predictable moment, weeks later, when they run out. A calendar send cannot find that moment. A repurchase trigger can.

We built the triggers alongside the brand and packaging rather than bolting them on afterwards, so the email that arrives sounds like the tin it is reminding you about.

• Revenue up 120% in year two – the year repeat purchase, not acquisition, does the work.
• 6,500+ community members and customers acquired across all channels within 24 months.
• 10 SKUs and 15 retail stockists – more products and more places to buy means more behaviour worth responding to.

Read the case study. The Collective Supplement Co shows the same triggers compounding over a longer run: 243%, then 120%, then 211% revenue growth across three years.

The Antimony position

This is the architecture behind our ecommerce lifecycle work for brands like Femme Connection and Sada Men: behaviour first, calendar second. Request the Brand Retention Audit to see which triggers your lifecycle is missing.

Key takeaways

• Behavioural triggers respond to what a customer did; calendar sends respond to what month it is.
• Five foundations: post-purchase onboarding, browse abandonment, repurchase reminders, review requests, win-back.
• Timing beats copy – especially for repurchase, where a week early is service and a week late is a lost customer.
• Triggers and campaigns are complements: build the triggers first, then let campaigns run on top.
