7 Best Klaviyo Alternatives in 2026
Klaviyo earns its reputation on ecommerce automation. It also gets expensive fast as your list grows. These are the platforms worth moving to, ranked by what you actually sell.
Nobody leaves Klaviyo because the product is bad. People leave because the invoice grows faster than the revenue attributed to it, especially between 20,000 and 100,000 contacts. The good news is that the gap closed. Omnisend, Brevo, and Customer.io now ship the flows that mattered most in Klaviyo (abandoned cart, browse abandon, post purchase, winback) at a fraction of the price at scale. Below is the ranked list, with the migration story for each.

What we love · what we don't
What we love
- Every alternative here imports Klaviyo lists and segments without a developer.
- At 20,000 contacts and up, the savings are usually large enough to fund paid acquisition.
- SMS is bundled in more places than it used to be, so the stack gets simpler.
What we don't
- Nothing matches Klaviyo on predictive analytics and revenue reporting yet.
- Rebuilding mature flows takes a week of real work, not an afternoon.
The ranking
1. Omnisend
Omnisend was built for ecommerce from day one, so the flow library reads familiar the moment you land: cart abandonment, browse abandonment, post purchase, winback.
Email plus SMS plus push sit in one automation, which Klaviyo charges separately for.
Pricing stays predictable at the list sizes where Klaviyo starts to hurt.
Pros
- Ecommerce flows out of the box
- Email, SMS and push in one flow
- Cheaper at 20K+ contacts
- Direct Klaviyo import
Cons
- Reporting is shallower than Klaviyo
- Predictive analytics is limited
Who it's for
Stores that want Klaviyo behavior without Klaviyo pricing.
Skip it if
You depend on predictive lifetime value modeling.
2. Brevo
Brevo bills on send volume, so a large but quiet list costs almost nothing to keep.
Automation, SMS and a usable CRM are included rather than sold as add ons.
The tradeoff is a less commerce specific flow library, so expect to build a few automations by hand.
Pros
- Pay per send pricing
- CRM and SMS included
- Generous free tier
Cons
- Fewer prebuilt commerce flows
- UI less polished
Who it's for
Operators whose main complaint is the bill.
Skip it if
You need deep Shopify revenue reporting.
3. ActiveCampaign
If your business is part store and part service, ActiveCampaign covers both with conditional logic Klaviyo does not try to match.
The CRM is included, so sales follow up lives beside the store automations.
Commerce reporting is weaker, so revenue attribution takes setup.
Pros
- Deepest automation builder
- CRM included
- Strong deliverability in testing
Cons
- Learning curve
- Commerce reporting needs work
Who it's for
Hybrid businesses with sales and store motions.
Skip it if
You only send commerce flows.
4. MailerLite
For a store with a handful of products and two or three automations, Klaviyo is overbuilt and MailerLite is enough.
Landing pages and forms are included, so a lot of stores drop a second tool on the way over.
Automation is capable but shallow compared to what you are leaving.
Pros
- Easiest to use
- Landing pages included
- Honest pricing
Cons
- Light automation
- Basic commerce reporting
Who it's for
Small stores and solo operators.
Skip it if
You run more than a few branching flows.
5. Customer.io
Customer.io is built on events and attributes, which is the same mental model you already use in Klaviyo, so segments port over conceptually without much rework.
Messaging spans email, SMS, push and webhooks in a single journey.
It expects someone technical to send the events, so budget setup time.
Pros
- Powerful event segmentation
- Multi channel journeys
- Scales without contact tax
Cons
- Needs developer setup
- Higher entry price
Who it's for
Product led brands with engineering help.
Skip it if
Nobody on the team can send events.
6. Mailchimp
Mailchimp is the default answer for teams who want no learning curve and no surprises in the UI.
The commerce side never recovered from losing the deep Shopify integration, so treat it as a campaign tool with light flows.
Watch the pricing, since it climbs on contacts the same way Klaviyo does.
Pros
- Familiar to everyone
- Huge template library
- Broad integrations
Cons
- Weak commerce depth
- Contact based pricing climbs
Who it's for
Campaign led stores with simple automation.
Skip it if
Flows are your main revenue driver.
7. GetResponse
If you sell digital products alongside physical ones, GetResponse consolidates the funnel and the webinar into the same subscription.
Commerce flows exist but are lighter than Omnisend or Customer.io.
Pros
- Native webinars
- Funnel builder included
- Good value
Cons
- Wide but shallow commerce features
Who it's for
Sellers who run launches and webinars.
Skip it if
You are a pure catalog store.

Frequently asked questions
Almost always price at scale. Klaviyo bills on stored contacts, so a growing list raises the invoice whether or not those contacts open anything. The second reason is stack consolidation, since SMS and push are separate line items.
