5 E-commerce Marketing Automation Workflows That Drive Most of the Revenue

Updated October 28, 2026. Benchmarks come from Klaviyo’s published email benchmarks and Baymard Institute’s cart abandonment research.

Why automation outperforms campaigns in e-commerce

A campaign goes to everyone on the same day with the same message. A workflow, also called a flow, goes to one person at the moment they do something: sign up, add to cart, buy, or stop buying. Because the message matches what the customer just did, it converts better.

Klaviyo’s benchmark data puts numbers on this. Across the accounts it measured, campaigns made up 94.7% of email sends but flows generated nearly 41% of email revenue. Flows had click rates of 5.58% against 1.69% for campaigns, and placed-order rates about 13 times higher. Abandoned cart flows averaged $3.65 in revenue per recipient, against $0.11 for standard campaigns.

1. Welcome series

Trigger: someone joins your email or SMS list. Filter: has not purchased yet.

• Email 1, immediately: deliver whatever you promised at signup and introduce the brand in two or three sentences.
• Email 2, day 2: social proof: reviews, best-sellers, a customer story.
• Email 3, day 4: answer the objections that stop first purchases: delivery times, returns, sizing, ingredients.
• Email 4, day 7: a reminder if an offer is expiring.

This is the workflow where your brand voice matters most, because it is the first private conversation with a new customer. A welcome series that sounds like every other store wastes the highest-attention moment you will get.

2. Abandoned cart

Trigger: started checkout or added to cart without ordering. Baymard Institute’s average across dozens of studies puts online cart abandonment at about 70%, so this is usually the highest-earning flow.

• Message 1, about 1 hour later: a plain reminder showing the exact items. No discount.
• Message 2, about 24 hours later: reviews of the specific product, or answers to common questions about it.
• Message 3, about 72 hours later: an incentive only if your margins allow it, such as free shipping.

Avoid offering a discount in the first message. Customers learn quickly that abandoning a cart produces a coupon.

3. Browse abandonment

Trigger: viewed a product page, did not add to cart. Filter: not already in the abandoned cart flow and not emailed by this flow in the last two weeks.

One or two messages are enough: the product they viewed, then similar products or the collection it belongs to. Revenue per recipient is lower than abandoned cart, but the trigger fires far more often, so total revenue can be meaningful.

4. Post-purchase

Trigger: placed an order. Split first-time buyers from repeat customers.

• Order confirmation and shipping updates: clear, branded, with no upsell clutter.
• How to get the most from the product: care instructions, setup guides or recipes. This reduces returns and support tickets.
• Review request: timed for after the customer has used the product, not the day it ships.
• Cross-sell: one complementary product, based on what they bought.

5. Win-back

Trigger: no order for a period that matches your buying cycle. For consumables that may be 45 to 60 days; for furniture it may be a year. Start with “here is what is new”, then a stronger offer if there is no response, then suppress inactive subscribers to protect deliverability.

How to build these without a big team

1. Connect store data first. Workflows depend on reliable events: viewed product, added to cart, started checkout, placed order. Check they arrive in your email platform before writing a single email.
2. Launch simple versions of all five. One to three messages each is enough to start earning.
3. Set exclusions. Someone who just bought should not receive a cart reminder an hour later.
4. Measure revenue per recipient and placed-order rate, not open rates, which are distorted by privacy features in mail apps.
5. Improve one flow per month. Test timing, subject lines and content, one variable at a time.

Common mistakes

• Discounting in every flow, which trains customers to wait.
• Generic copy that could belong to any store. Automation scales your voice; make sure it is yours.
• No frequency cap, so one customer gets four automated emails in a day.
• Never revisiting flows after launch. Products, prices and policies change; old flows quietly go stale.

Bottom line: Build these marketing automation workflows one at a time and measure each before adding the next. Marketing automation workflows pay off when the basics run reliably, not when there are dozens of them. Review your marketing automation workflows every quarter and retire the ones that no longer earn.

Frequently asked questions about marketing automation workflows

What is the most profitable e-commerce automation?

Abandoned cart, in most stores. Klaviyo’s benchmarks show it averages $3.65 revenue per recipient, far above standard campaigns.

How many emails should an abandoned cart flow have?

Two or three, spread over about three days. More than that tends to raise unsubscribes without adding much revenue.

Which platform should I use?

Choose the one that connects cleanly to your store’s data. For Shopify stores, Klaviyo is widely used; Mailchimp, Omnisend and others offer similar flow builders. See our Mailchimp vs Kit comparison.
