Shopify email automation that doesn't triple your bill at 10K contacts

Built-in post-purchase sequences, abandon cart flows, and win-back campaigns — priced for stores still proving ROI.

Cancel any time. No contract. Flat pricing at every contact tier.

Every email platform in the Shopify ecosystem follows the same pricing model: the more contacts you collect, the more you pay — exponentially. Klaviyo prices contacts on a sliding scale that starts looking manageable at 1,000 subscribers and turns punishing the moment your store gains traction. At 5,000 contacts you're paying around $100/mo. At 10,000 contacts, that becomes $150-170/mo. At 25,000 contacts, you're looking at $400-500/mo. At 50,000, close to $800/mo. The platform didn't get better. Your bill just grew because your marketing worked.

The stores caught hardest by this model are the ones scaling fastest. You've built your list to 8,000 or 12,000 subscribers through paid acquisition, organic content, or a product that genuinely moves. Your email list is growing. Your Klaviyo invoice is growing faster. And you're watching your email marketing costs balloon before you've had time to prove the ROI on the automations you set up six months ago.

Shopify email automation should cost a fixed amount per month, regardless of whether your list grows from 5,000 to 50,000. Flowbase is priced that way.

The Klaviyo pricing cliff hits precisely when Shopify stores need margin most

Klaviyo's model is rational from their perspective: more contacts means more sends, more deliverability infrastructure, more revenue potential for your store. They want a share of what your list earns. The problem is they charge that share upfront, before your automations produce results, and the pricing jump happens at exactly the growth stage where Shopify stores are most margin-sensitive.

A store crossing 10,000 contacts is typically 18-24 months old. It's still experimenting with product-market fit. It's reinvesting revenue into inventory and acquisition. A $200/mo increase in its email platform bill — triggered purely by list growth, not by campaign performance — arrives at the worst possible moment. The alternatives at this tier are either shallow (MailerLite's Shopify integration doesn't fire on purchase events or product-specific behavior) or expensive in a different direction (ActiveCampaign requires manual Shopify sync setup and doesn't natively read cart or purchase data).

The post-purchase sequence — the thank-you flow, the cross-sell trigger, the review request, the replenishment reminder — is where Shopify email marketing actually generates return. These are purchase-event automations that require deep Shopify data: what the customer bought, when they bought it, what they've bought before, what's still in their cart. MailerLite can send an email after a purchase. It cannot branch that email based on the specific product purchased, the customer's order history, or the category of the item. That capability lives in Klaviyo. And Klaviyo charges you more for it every time your list grows.

Introducing Flowbase

Flowbase connects directly to Shopify's purchase, cart, browse, and customer data and builds automation flows on top of it — the same trigger logic Klaviyo uses — at a flat monthly rate that doesn't change when your contact count grows. You get post-purchase sequences, abandoned cart recovery, browse abandonment, win-back campaigns, and replenishment reminders. The price you pay at 5,000 contacts is the price you pay at 50,000 contacts.

What You Get — $49/mo

Shopify native purchase-event triggers — Flowbase reads your Shopify order data directly: product purchased, collection, SKU, order value, purchase frequency, and customer lifetime value. Every automation branches on real purchase behavior, not just "did they buy something."

Post-purchase sequence builder — Set up a thank-you series, a cross-sell flow, and a review request sequence in one visual canvas. Each email fires based on what the customer bought and what they've bought before, not a one-size broadcast.

Abandoned cart recovery with product context — Cart abandonment emails that reference the specific product left behind, its price, its stock status, and any active discount on that SKU. Not a generic "you left something behind" message.

Browse abandonment triggers — Fires when a visitor views a product page without adding to cart. Branches based on the product category, the visitor's purchase history, and how many times they've viewed that item.

Win-back campaigns with purchase-gap logic — Identify customers who haven't bought in 60, 90, or 120 days and trigger a re-engagement sequence tuned to their previous purchase category.

Replenishment reminders — For consumable products, set a replenishment window per product SKU. Flowbase sends a reminder email when that window closes, based on each customer's actual purchase date.

Flat contact pricing — One price per plan tier, covering unlimited contacts. Your bill doesn't change when your list grows.

Deliverability monitoring — Per-domain reputation tracking, bounce management, and inbox placement reporting built into every account.

Why $49/mo

Klaviyo at 10,000 contacts costs $150-170/mo. At 25,000 contacts, $400-500/mo. At 50,000 contacts, roughly $800/mo. MailerLite at those same tiers costs $50-100/mo but lacks purchase-event branching. ActiveCampaign requires a third-party Shopify sync connector (typically $20-50/mo extra) and manual flow setup for purchase-based triggers. Flowbase at $49/mo covers the automation capability that only Klaviyo currently provides, at a price that doesn't scale with your list size.

Who This Is For

You run a Shopify store with between 3,000 and 50,000 email subscribers and you're paying Klaviyo more each month than you were three months ago without changing how you use it.

You've set up the core post-purchase sequence and abandoned cart flow and you're watching your Klaviyo bill grow faster than the revenue those flows generate.

You sell consumable or repeat-purchase products and you want automated replenishment reminders that fire per customer based on their actual purchase date, not a broadcast calendar.

You're migrating off Klaviyo and you don't want to rebuild your flows from scratch in a tool that doesn't read Shopify purchase data natively.

You manage email for a Shopify store at an agency and you're tired of explaining to clients why their email platform costs $400/mo when their list hits 25,000.

You want a fixed email marketing line item in your monthly budget, not one that fluctuates every time a paid campaign runs well.

Frequently Asked Questions

What does "Shopify email automation alternative to Klaviyo" actually mean?
Flowbase reads the same Shopify data Klaviyo reads — purchase events, cart events, browse events, customer lifetime value, product SKU and collection — and builds automation flows on top of it. The difference is pricing: Flowbase charges a flat monthly rate that doesn't increase as your contact count grows, where Klaviyo charges per contact tier.

How does Flowbase compare to MailerLite for Shopify?
MailerLite connects to Shopify and can send emails after purchases. It cannot branch automation flows based on which product was purchased, the customer's order history, or product-level attributes like SKU, collection, or replenishment window. Flowbase reads all of that data natively, which is what makes purchase-specific sequences possible.

How long does setup take?
Connecting Flowbase to your Shopify store takes under five minutes via OAuth. The post-purchase sequence template, abandoned cart flow, and win-back campaign ship as pre-built templates with Shopify data fields already mapped. Most stores have their first automation live within two hours of connecting.

What happens when my contact list grows past the plan limit?
Flowbase plans cover contact ranges, not exact counts. The Starter plan covers up to 25,000 contacts. The Growth plan covers up to 100,000. If you grow past your current plan's ceiling, you move to the next tier — one price jump, not a per-thousand-contact sliding scale. You'll see the tier ceiling clearly in your dashboard before you reach it.
