Shopify Email Marketing: The 7 Flows That Do Most of the Work

The short version: you don't need more email campaigns. You need seven automated flows running in the background. They send 5% of the volume and earn close to 41% of email revenue [4]. Here's the set, in priority order, and where Hubi takes the build off your plate.

Key Takeaways

• Flows beat blasts. Automated emails account for nearly 41% of total email revenue while making up only 5.3% of sends [4]. If you only send manual campaigns, you're leaving the highest-converting email type switched off.
• Start with three, not thirty. Welcome, abandoned checkout, and a post-purchase flow cover the moments where buyers are actually deciding. Build those first, then expand.
• Cart abandonment is the obvious win. Roughly 70% of ecommerce carts get abandoned [3]. A two or three email recovery flow is the fastest revenue you'll add this month.
• Email still pays. Ecommerce email marketing returns somewhere around $36 to $42 for every $1 spent [1]. The leverage is in setup, not send volume.
• Where Hubi fits: Hubi can draft the copy, build the flow logic in Klaviyo, and wire it to your Shopify events, then report back. It does not replace your judgment on offers, brand, and discount strategy, and it is a marketing agent, not a help desk.

Intro

Open your Shopify admin and look at the last 30 days of email revenue. If almost all of it came from manual campaigns, your store is running on one cylinder. The other cylinder, automated flows, is the one that fires while you sleep, and it's usually switched off or half built.

Here's the bottom line. You don't need a bigger campaign calendar. You need a small set of flows that trigger on what shoppers actually do: sign up, abandon a cart, place an order, go quiet. Those moments convert because the timing is right, not because the copy is clever.

Below are the seven flows worth your time, ranked by how fast they pay back. Build the first three this week. Add the rest as you have time. Every one of them works whether you build it by hand or hand it to an agent.

What "Shopify email marketing" actually means

Shopify email marketing is the practice of sending automated and manual emails to your store's contacts, triggered by Shopify store events like signups, checkouts, and purchases, to drive sales and repeat orders. It splits into two halves.

The first half is campaigns: the one-off emails you send to a list, like a sale announcement or a product launch. The second half is flows (also called automations): emails that send themselves when a shopper does something specific.

You can run both from Shopify Email, the native tool, or from a dedicated platform like Klaviyo or Omnisend that plugs into your store. Native tools are fine for simple campaigns. Once you want serious flow logic, segmentation, and reporting, most stores move to a dedicated platform. The flows below apply either way.

Campaigns vs flows: where the money is

The takeaway is blunt. Flows are a tiny share of your sending and close to half your email revenue [4]. If you have limited hours, you spend them on flows first.

The 7 flows, in priority order

1. Welcome flow

Fires when someone subscribes, usually through a signup popup. This is your highest-intent moment: they just raised their hand. Send a 3 to 4 email sequence that introduces the brand, sets expectations, and includes a first-order incentive if your margins allow it.

2. Abandoned checkout flow

Fires when a shopper enters checkout and doesn't complete. With cart abandonment hovering near 70% across ecommerce [3], this is the single most valuable flow you can build. Two or three emails: a reminder, a nudge with social proof or product details, and an optional last incentive.

3. Browse abandonment flow

Fires when a known contact views products but never starts checkout. Lower intent than an abandoned cart, but higher volume. One or two gentle emails referencing what they looked at.

4. Post-purchase flow

Fires after an order. Confirm the purchase, set delivery expectations, and start the relationship. This flow lowers support tickets and sets up the next order. Add a review request a week or two after expected delivery.

5. Winback flow

Fires when a past customer goes quiet for a set window, say 60 or 90 days. Remind them you exist, show new or bestselling products, and consider a comeback offer. Cheaper than acquiring a new customer.

6. Replenishment flow

For consumables. Fires a set number of days after purchase, timed to when the product runs out. "Time to restock?" with a one-click reorder. Only relevant if you sell things people use up.

7. Back-in-stock and price-drop flows

Fire when a product a contact wanted becomes available again or drops in price. Demand already exists, you're just closing the loop. High conversion, low volume.

A simple build order

Don't try to launch all seven at once. Use this sequence:

1. Week 1: Welcome + abandoned checkout. These cover the two highest-intent moments and pay back fastest.
2. Week 2: Post-purchase + browse abandonment. One protects repeat orders, the other catches mid-funnel intent.
3. Week 3 and beyond: Winback, replenishment, back-in-stock, as they fit your catalog.

Write the copy in your real brand voice, keep each email to one job, and turn flows on one at a time so you can read the numbers cleanly.

How Hubi builds these flows for you

The slow part of flow building isn't strategy, it's the doing: writing each email, setting the triggers and delays, wiring them to the right Shopify events, and checking the logic. That's the part you can hand off.

You message Hubi in Slack like a teammate:

Hey Hubi, build our abandoned checkout flow in Klaviyo.
3 emails over 24 hours. Match our brand voice from the welcome flow.
No discount on email 1 or 2, 10% off on email 3. Then show me before it goes live.

Here's what Hubi does with that:

• Drafts all three emails in your brand voice, with subject lines and preview text.
• Builds the flow logic in Klaviyo: trigger on started checkout, delays, and the skip conditions so buyers who convert stop receiving emails.
• Connects it to the right Shopify checkout event.
• Reports back with a preview and waits for your approval before anything sends.

The honest caveat: Hubi does the build and the drafting, but you own the decisions that matter: which offers to run, how deep to discount, and whether the copy is on brand. Hubi is a marketing and growth agent, not a help desk or a replacement for your strategy. Review every flow before you switch it on, and keep an eye on the first week of sends.

When not to lean on flows

Flows are not a fix for a weak offer or a thin list. If almost nobody is subscribing, fix the signup popup and the lead capture first, because an empty flow sends to no one. If your product has no repeat-purchase logic, skip replenishment. And don't over-automate to the point that every email feels robotic. The best flows read like a human wrote them, because timing plus a real voice is what converts.

How to start this week

1. Check your email platform for which flows are already live (many stores have a half-built welcome flow they forgot about).
2. Turn on or rebuild the abandoned checkout flow first. It's the fastest payback.
3. Write or refresh the welcome flow with a clear first-order path.
4. Set up post-purchase next, including a review request.
5. Turn flows on one at a time and read the numbers before adding the next.

FAQ

Do I need Klaviyo, or is Shopify Email enough?

Shopify Email handles basic campaigns and a few simple automations well, and it's cheap. Once you want layered flow logic, real segmentation, and deeper reporting, most growing stores move to Klaviyo or Omnisend. Start native if you're small, upgrade when flows become a real revenue line.

Which flow should I build first?

The abandoned checkout flow. With around 70% of carts abandoned across ecommerce [3], recovering even a slice of that is usually the fastest revenue you'll add, and the trigger fires on shoppers who were one step from buying.

How many emails should a flow have?

Welcome: 3 to 4. Abandoned checkout: 2 to 3. Post-purchase: 2 to 3 spread over the delivery window. More isn't better. Each email should have one clear job.

Will flow emails annoy my customers?

Not if they're timed and relevant. Always add skip conditions so people who convert stop getting the sequence, and cap how often a single contact can enter overlapping flows. Relevance is what keeps unsubscribes low.

How much can email marketing actually return?

Ecommerce email marketing tends to return roughly $36 to $42 for every $1 spent [1], though your number depends on list quality, offer, and how well your flows are built. The point isn't the exact figure, it's that flows are high-leverage once they're set up.

What's a good open rate for ecommerce email?

Recent benchmarks put the average ecommerce email open rate around 30% [2]. Treat that as a rough floor to beat, not a target. Your flow emails usually outperform broadcast campaigns because they're triggered by intent.

Can I automate flow building without a marketing team?

Yes. A tool like Hubi can draft the emails, build the flow logic in Klaviyo, and connect it to your Shopify events, then hand it back for your approval. You still make the offer and brand calls, but the build work comes off your plate.

The takeaway

Shopify email marketing isn't about sending more. It's about building the handful of flows that catch shoppers at the moments they're deciding: signing up, abandoning a cart, buying, and going quiet. Those flows send a fraction of your email and earn close to half the revenue [4]. Build the first three this week, write them in a real voice, and turn them on one at a time.
