Definition

A drip campaign is a pre-planned series of automated messages sent to a user at fixed intervals or when trigger conditions are met.

How a drip campaign works

A drip campaign is built on three elements: an entry trigger (what moves a user into the
series), a sequence of steps (content plus intervals) and an exit condition (the goal was
met, or the cycle ended).

An example onboarding series for a new e-commerce buyer:

Day 0  -> Welcome - here is your promo code
Day 2  -> Bestsellers in the category of the first purchase
Day 5  -> A selection of similar products plus reviews
Day 10 -> A reminder about the unused promo code
Day 15 -> Content - how to choose [category] - with no direct selling

Exit from the series: the user makes a second purchase and moves into a different segment.

Drip versus trigger: when to use which

Criterion	Drip campaign	Triggered send
Launch logic	A schedule (intervals)	A specific event
Predictability	High	Depends on behaviour
Examples	Onboarding, nurturing, re-engagement	Abandoned cart, price drop
Personalization	By segment at entry	By current context

The best campaigns combine both: the drip series provides the structure, event-based triggers
provide dynamic inserts at the right moment.

Key e-commerce scenarios

Onboarding a new buyer. The goal is to reach a second purchase. Four or five messages across 2–3
weeks: a welcome, social proof, a category selection, a reminder.

Nurturing a lead. The user has registered but bought nothing yet. A content series: how to
choose, comparisons, case studies. The goal is removing the barrier to a first purchase.

Win-back. The user has not bought for 60+ days. A series of three messages: we miss you, here is
what has changed, a final offer with a discount.

Important: every step of a drip series should add value rather than simply push towards a
purchase. Educational content at steps 2–3 reduces attrition from the series and raises loyalty to
the brand.

Common mistakes

Messages that are too frequent. More than two a week in an onboarding series is a direct route
to unsubscribes.
One series for everyone. A buyer of children’s goods and a buyer of electronics get identical
recommendations. Splitting into 3–5 branches by the category of the first purchase delivers a
substantial gain in click-through rate.
No exit condition. A user who bought at step 2 keeps receiving offers in the same category —
irritating, and it creates irrelevant noise.
No A/B testing of the steps. The subject line, the send time and the length of the series all
affect the result — test at least the busiest step, which is usually the first.

Frequently asked questions

How does a drip campaign differ from a triggered send?

A drip campaign runs on a schedule: step 1, then step 2 two days later, then step 3 five days after that. A triggered send fires exactly at the moment of an event — a cart abandoned, a price dropped, a birthday. In practice both approaches are combined: the drip provides the series, the trigger provides a specific message inside it.

How many steps are optimal for an e-commerce drip campaign?

Three to seven steps for most scenarios. An onboarding series can hold 5–7 messages across 2–3 weeks. A welcome series for a new buyer — 3–4 messages across 10 days. The main principle: every step adds value rather than simply reminding people you exist.

How do you measure the effectiveness of a drip campaign?

The headline metrics for the series as a whole: conversion to the target action, attributed revenue, and attrition from the campaign (unsubscribes plus inactives). Per step: open rate, click rate and micro-conversions (add to cart, category view). Compare against a holdout group of users outside the campaign.

Can content be personalized inside a drip campaign?

Yes — and it lifts effectiveness substantially. Instead of one shared series, several branches are built: a fashion buyer receives a selection of new collection arrivals, an electronics buyer receives accessories for the item they bought. The logic branches by segment, behaviour or category preference.
