7 Klaviyo Alternatives for Ecommerce Shops Under $1M ARR (2026)

If you are leaving Klaviyo purely on cost but still need real ecommerce automation, Omnisend is the most natural landing spot. It was built from the ground up for online stores, so the flows you depend on — abandoned cart, browse abandonment, cart recovery, post-purchase, and win-back — are pre-built and ready to switch on, not something you assemble from generic triggers. That matters enormously during a migration: you are replicating Klaviyo muscle memory, not relearning automation from scratch.

Where it pulls ahead for sub-$1M shops is the combination of a free tier (up to 250 contacts) and email + SMS living in the same workflow, so you can build a single cart-recovery sequence that sends an email, waits, then fires an SMS — without bolting on a second tool. The Standard plan starting around $16/mo keeps early-stage stores comfortably under budget, and pricing climbs more gently than Klaviyo's profile-based meter at the list sizes most growing stores actually sit at.

It is not as deep as Klaviyo on advanced predictive analytics, and very large senders will eventually feel the Pro tier, but for the store doing six figures that wants Klaviyo-grade flows without Klaviyo-grade bills, this is the default recommendation.

Brevo's superpower for cost-conscious stores is its pricing model: it bills on the number of emails you send, not the number of contacts you store. For a store with a large but loosely-engaged list — say 25,000 subscribers you email a few times a month — that flips the economics completely versus Klaviyo, where every one of those profiles is a line item whether you message them or not.

Beyond the price model, Brevo is a genuine all-in-one: email automation, SMS, a built-in CRM, and even transactional email under one roof. The automation builder handles ecommerce triggers like abandoned cart and order confirmation, so your revenue flows survive the move. The free plan (300 emails/day) is enough to validate the platform, and paid plans start around $9/mo, scaling on send volume rather than punishing list growth.

The trade-off is that its ecommerce templates and flow library are not as polished or store-specific as Omnisend's or Klaviyo's — you do a bit more building yourself. But if your list is big and your send cadence is moderate, no other tool on this list will save you more money as you scale.

Drip is the alternative for stores that left Klaviyo reluctantly and refuse to compromise on automation depth. It is ecommerce-native in the same way Klaviyo is — it understands shopping behavior, tracks product views and purchase history, and lets you build genuinely sophisticated behavioral flows triggered by what customers actually do on your store. If your Klaviyo setup leaned heavily on segmentation and conditional logic, Drip is the platform here most likely to reproduce it faithfully.

Crucially, every feature is included on every plan — there is no tiering away the automation you need to a higher bracket. Pricing starts around $39/mo for 2,500 contacts with all capabilities unlocked, which makes budgeting predictable as you grow. For a store whose email channel is a serious revenue driver rather than an afterthought, that all-in approach removes the "which features do I lose at this price" anxiety that plagues tiered competitors.

The honest catch is that the entry price is higher than MailerLite or Brevo, so it is overkill for a store that just needs a newsletter and one cart-recovery flow. But for automation-led ecommerce brands under $1M that want Klaviyo-level flows without Klaviyo-level scaling costs, it hits the sweet spot.

For the earliest-stage stores — the ones with a few thousand subscribers and a tight budget — MailerLite offers the gentlest on-ramp on this list. Its free tier covers up to 1,000 subscribers and, unlike many "free" plans, still includes automation workflows, so you can run an abandoned-cart or welcome sequence without paying a cent while you find product-market fit.

Paid plans start around $10/mo (Growing Business), which is roughly half the entry cost of many ecommerce-specific competitors, and the interface is clean enough that a non-technical founder can build flows without a learning-curve tax. It integrates with Shopify and WooCommerce to pull in store data, covering the core ecommerce automations most small shops actually use day to day.

It is deliberately simpler than Klaviyo or Drip — you will not find the same depth of predictive segmentation or granular conditional logic — and very large or automation-heavy stores will outgrow it. But that simplicity is exactly the point for a sub-$1M store that wants reliable flows, a beautiful builder, and the lowest possible bill while it scales.

ActiveCampaign is the power user's alternative — the one to choose when you want marketing automation and a real CRM working from the same customer data. For a store under $1M that sells in a more considered, higher-ticket way (think furniture, jewelry, or B2B-flavored ecommerce), the ability to track a contact across both marketing flows and a sales pipeline is something Klaviyo simply does not do as well.

Its automation builder is arguably the most flexible on this list, with deep conditional branching, lead scoring, and ecommerce triggers that connect to Shopify and WooCommerce. Plans start around $15/mo for 1,000 contacts, which is competitive at the low end, though the more advanced automation and CRM features live on the Plus ($49/mo) and Pro ($149/mo) tiers.

The catch is complexity: ActiveCampaign rewards investment in learning it, and a store that just wants three simple flows will find it heavier than Omnisend or MailerLite. But if your reason for leaving Klaviyo is that you have outgrown pure email and need automation plus sales tooling under one roof — without enterprise pricing — this is the standout choice.

Mailchimp is the familiar all-rounder, and for many founders it is the first email tool they ever touched. That familiarity has real value during a migration — the drag-and-drop builder, templates, and reporting are approachable, and its Shopify and WooCommerce integrations support the standard ecommerce automations like abandoned cart and product retargeting. If you want a known quantity with a huge integration ecosystem behind it, Mailchimp delivers.

For sub-$1M stores, the caution is pricing direction. Mailchimp bills on contacts (Essentials from ~$13/mo, Standard from ~$20/mo), and like Klaviyo that meter rises as your list grows — so it solves the "I want something familiar and capable" problem more than the "I want dramatically cheaper at scale" problem. The free tier (up to 250 contacts) is fine for validation, but the Premium tier's ~$350/mo jump shows how steep the top end gets.

Choose it if ease of use, brand familiarity, and breadth of integrations matter more to you than squeezing out the lowest cost per contact. Just go in with eyes open about how the bill behaves as you scale, and revisit Omnisend or Brevo if cost becomes the deciding factor.

Kit (formerly ConvertKit) is the pick for creator-led DTC brands — the store that is really a personal brand, newsletter, or community selling both digital products and physical merch. Its automation and tagging system is built around audience relationships and content, which is a different philosophy from Klaviyo's transaction-first ecommerce focus, and for the right brand that difference is a feature, not a bug.

If your revenue mix leans on courses, memberships, or digital downloads alongside a Shopify store, Kit's commerce features and clean subscriber management make it easy to sell and nurture from one list. The free plan reaches up to 10,000 subscribers (with limited features), and the Creator plan starts around $39/mo, which is reasonable for a brand whose email list is the business.

The honest limitation is that it is not a traditional ecommerce automation engine — you will not find the same depth of cart-abandonment and product-behavior flows that Omnisend, Drip, or Klaviyo offer. So it is a poor fit for a pure-play product store, but a strong one for a creator who sells things. Match it to your business model, not just your subscriber count.
