Flows vs Campaigns
Email MarketingAlso: Email Flows vs Email Campaigns · Automated Emails vs Broadcast Emails
Quick definition
Flows and campaigns are the two ways email marketing sends messages. A flow is an automated sequence triggered by a subscriber's behaviour, such as signing up or abandoning a cart. A campaign is a one-time broadcast sent to a list or segment on a date you choose.
How it varies across Australia
Australian ecommerce brands that lean heavily on flows tend to generate a disproportionate share of email revenue from a small number of automated sequences, while brands that rely mostly on campaigns see revenue swing hard with send frequency. The businesses with the steadiest email performance usually run both, not one instead of the other.

An automated sequence triggered by something a subscriber does, like joining a list or abandoning a cart.

Sent once, per scheduleWhat it actually means
A flow runs on behaviour. Someone joins your list, abandons a cart, or hasn't opened an email in three months, and the flow reacts without anyone touching a keyboard. A campaign runs on the calendar. You decide the offer, the segmentation, and the send date, and it goes out once.
The confusion happens because both live in the same email platform and both land in the same inbox. But they solve different problems. Flows handle lifecycle marketing: welcome sequences, abandoned cart recovery, post-purchase follow-up, win-back sends. Campaigns handle moments: a sale, a launch, a newsletter, a seasonal push.
The mistake most businesses make is running one and neglecting the other. All-flow accounts miss the revenue spike a well-timed campaign can produce. All-campaign accounts leave money sitting in abandoned carts because nobody's watching behaviour in real time.
Email automation is what makes flows possible at all. Without it, every triggered email would need a human to notice the trigger and hit send, which doesn't scale past a handful of subscribers. Segmentation improves both, but it's non-negotiable for campaigns since a broadcast sent to everyone performs worse than one sent to the right slice of the list.
A flow is a system you build once and forget. A campaign is a decision you make every single time.
How it shows up
Flows show up in your platform's automation tab as sequences with trigger conditions, wait steps and branching logic. Campaigns show up in the send calendar as discrete, dated broadcasts. In reporting, flows get judged on a rolling basis (revenue per recipient over time) while campaigns get judged send by send, comparing open rate, click-through rate and revenue against the last similar send.
The Australian context
Australian ecommerce brands running on Shopify or Klaviyo tend to build the standard three flows fast (welcome, abandoned cart, post-purchase) then stop. Fewer build win-back or browse-abandonment flows, which is where the remaining opportunity usually sits. On the campaign side, Australian sending patterns cluster around EOFY and the pre-Christmas period, which means most of the annual campaign learning happens in a compressed window rather than spread evenly across the year.

Common questions
Should a new business start with flows or campaigns?
Start with flows. A welcome sequence and abandoned cart flow work from day one with almost no subscribers and keep earning without ongoing effort. Campaigns need a list worth sending to, so they earn their place once you have an audience to talk to.
Do flows and campaigns use the same segmentation?
The logic differs. Flows segment on behaviour and trigger conditions built once into the sequence. Campaigns segment on whatever criteria fits that specific send, which can change every time. Both rely on clean list data to work properly.
Which one drives more email revenue?
For ecommerce, flows often produce a large share of email revenue from a small number of sequences because they catch high-intent moments like cart abandonment. Campaigns produce revenue in spikes around specific sends. Most mature programmes need both to hit their potential.
Can a campaign trigger a flow?
Yes. Many platforms let a campaign click or open feed into a flow's trigger conditions, so someone who clicks a campaign link can enter a follow-up flow automatically. This is a common way to bridge the two without manual list management.
