Best Klaviyo alternatives in 2026
Klaviyo is the best e-commerce email platform there is, and it isn't particularly close. Its behavioural segmentation scores 9.0/10 on G2 — the highest-rated capability in its profile — the Shopify data sync is genuinely deeper than anything else in the category, and it will tell you which specific flow produced which revenue rather than which email got opened. For a store, that attribution is the whole point.
The reason you're here is almost certainly February 2025, when Klaviyo changed what it bills you for. It used to charge on emails sent. It now charges on active profiles held — every contact capable of receiving email, including people who only ever hit checkout and never opted into marketing. Bills jumped overnight; pricing trackers cite examples going from $39 to $200, and $625 to $2,765, in a single cycle. The rating split tells the story: Klaviyo sits at 4.6/5 on G2 and 4.6/5 on Capterra, and 1.8/5 on Trustpilot — happy power users rate the product, and people who got the new invoice rate the billing.
One thing to weigh before you migrate, because it's the part these roundups skip: your list and consent records export fine, but your sending reputation does not come with you (budget 2–4 weeks of warm-up, up to eight to fully re-establish at Gmail and Microsoft), and Klaviyo's flows and segments are proprietary and wired into Shopify's event model. For a mature store with dozens of flows, leaving is a rebuild project, not an export. All pricing below was checked in July 2026; several vendors render prices through interactive sliders we could not capture directly, and those are marked.

The shortlist
AgentCeres
Top pickNot an email platform — say it up front. AgentCeres is a managed AI marketing team that CONNECTS to Klaviyo: a specialist drafts and clones campaigns, builds segments and writes the content inside your existing account, with sending and scheduling approval-gated. It's here because if your flows are fine and nothing new gets written, migrating solves the wrong problem. If the profile-based bill is your problem, go to Omnisend or Brevo below.
- Growth Officer
- Research agent
- SEO agent
- Social media agent
- Ads agent
- Influencer agent
- Launch & PR agent
- GEO agent
- Community agent
- Customer feedback agent
Pros- Different problem: it writes the campaigns, which is usually what's actually missing
- Connects to your existing Klaviyo — no migration, no warm-up, no rebuilding flows
- Drafting, cloning and segment-building run immediately; sending and scheduling wait for approval
- Email sits alongside SEO, social, ads and research specialists sharing the same product context
Cons- Not an ESP and not a Klaviyo replacement: no sending infrastructure, no deliverability management, no predictive analytics, no flow builder
- Does nothing about your profile-based bill — if that's the problem, this is the wrong entry
- No revenue attribution of its own — that stays Klaviyo's job
- We connect to Klaviyo, Mailchimp, Kit, Resend and SendGrid — NOT Omnisend, Brevo or Attentive
- Pricing:
- $39–$99/mo flat (annual $27–$69), on top of your ESP; 14-day trial, no card
- Best for:
- Stores whose flows work and whose campaigns never get written
Omnisend
The closest like-for-like e-commerce swap. Same job — email, SMS, push, Shopify-native flows — at a materially lower entry price.
Pros- Genuinely comparable e-commerce feature set; native email + SMS + push on one plan
- Standard from $11.20/mo (500 contacts); Pro from $41.30/mo (2,500 contacts, unlimited emails)
- SMS from around $0.007/segment at volume
Cons- Segmentation and predictive analytics are less sophisticated than Klaviyo's — this is the trade
- Smaller ecosystem and integration catalogue
- AgentCeres does not connect to Omnisend
- Pricing:
- Free (250 contacts, 500 emails/mo); Standard from $11.20/mo; Pro from $41.30/mo
- Best for:
- Shopify brands who want Klaviyo's shape without Klaviyo's invoice
Brevo
The direct answer to profile-based billing: it charges on emails sent, not contacts held. If you're paying for checkout-only profiles you never mail, this inverts exactly that.
Pros- Bills on send volume — dormant profiles stop costing money
- Large stored-contact allowance even on the free tier (300 emails/day)
- Includes SMS, WhatsApp and a basic CRM
Cons- E-commerce segmentation and revenue attribution are far shallower than Klaviyo's — a real downgrade for a store
- Less Shopify-native; UI less polished
- AgentCeres does not connect to Brevo
- Pricing:
- Free (300 emails/day); Starter from ~$9/mo; Business from ~$18/mo — vendor page is a JS slider we could not capture, so verify on brevo.com
- Best for:
- Large, infrequently-mailed lists where profile-based pricing hurts most
Mailchimp
The step sideways. Easier and cheaper at small scale, and the obvious pick if you were never really an e-commerce sender in the first place.
Pros- Easiest platform in the category to use; best template library
- Cheaper at small scale; broader general-marketing surface (landing pages, forms, ads)
- AgentCeres connects to Mailchimp
Cons- Store segmentation and revenue attribution are much shallower — a genuine downgrade for a Shopify brand
- Also bills on contacts held, and unsubscribed contacts keep counting — the same trap you're leaving
- Free tier is down to 250 contacts and 500 sends/month as of February 2026
- Pricing:
- Free (250 contacts); Essentials from $13/mo; Standard from $20/mo; Premium from $350/mo
- Best for:
- Senders who bought Klaviyo for e-commerce depth they never used
Kit (formerly ConvertKit)
The right answer if you're honest that you're a creator, not a store. Klaviyo's e-commerce machinery is dead weight for a newsletter.
Pros- Generous free Newsletter plan with unlimited broadcasts
- Strong creator monetisation — digital products, sponsorships, referrals
- AgentCeres connects to Kit
Cons- No meaningful e-commerce behavioural segmentation or revenue attribution — wrong tool for a store's lifecycle flows
- Automation depth well below Klaviyo's
- Free-tier subscriber cap is reported inconsistently — verify on kit.com
- Pricing:
- Free Newsletter plan; Creator from $33/mo; Pro from $66/mo
- Best for:
- Newsletters and creators paying e-commerce prices for nothing
Attentive
SMS-first rather than email-first. The right shape only if texting, not email, is where your revenue actually comes from.
Pros- SMS heritage and depth beyond Klaviyo's; strong compliance and deliverability tooling
- Built for brands where the text message is the primary revenue channel
- Real-time data activation across SMS, email, RCS and push
Cons- Pricing is not published — quote-only via sales, so you cannot self-serve or compare honestly
- Sales-led with likely higher minimums than Klaviyo at the SMB tier
- AgentCeres does not connect to Attentive
- Pricing:
- Not published — custom quote only. We will not invent a number for it
- Best for:
- Brands where SMS is the primary channel and budget isn't the constraint

Pick by the actual complaint. The profile-based bill is the problem and you still need e-commerce depth → Omnisend is the closest like-for-like at a fraction of the entry price. You're paying for dormant checkout profiles you never mail → Brevo bills on sends instead, which is precisely the inversion you want. You were never really an e-commerce sender → Mailchimp or Kit, depending on whether you're a business or a creator. SMS is where the revenue is → Attentive, though you'll have to talk to sales to find out what it costs.
Be honest about what leaving costs, though, because Klaviyo is the hardest platform on this list to leave and that's not marketing spin. Your contacts and consent records export cleanly. Your sending reputation does not — a new provider treats you as an unknown sender whatever your history, so budget 2–4 weeks of warm-up and up to eight to fully re-establish at the major inboxes. Your flows are Klaviyo-proprietary and built on its Shopify event model, so they get rebuilt by hand. Your predictive data — CLV scores, churn risk, next-order dates — does not migrate at all; it starts over. For a mature store, that's weeks of work. If the cost delta is genuinely large, do it. If it's marginal, the rebuild will eat the savings.
And the case where none of this is the issue. If your flows are running fine and the thing that never happens is the campaign — the seasonal push, the product launch, the re-engagement send — then a cheaper platform gets you the same silence for less. That's the only reason AgentCeres is on this page, and we'll be blunt about the shape: it is not an ESP, it has no attribution, and it will not lower your Klaviyo bill. It connects to the Klaviyo you already have; a specialist drafts and clones campaigns, builds segments and writes the content, and sending waits for your approval. If the invoice is the problem, Omnisend and Brevo above are the honest answers and we're not going to pretend otherwise.

FAQ
- What is the best Klaviyo alternative?
- Omnisend, for most people leaving. It's the closest like-for-like e-commerce platform — email, SMS and push with Shopify-native flows — starting at $11.20/month for 500 contacts against Klaviyo's $20 for the same band, and $41.30/month at 2,500 contacts with unlimited emails. The honest trade is that its segmentation and predictive analytics are less sophisticated than Klaviyo's. If your specific complaint is paying for profiles you never mail, Brevo bills on emails sent instead. All checked July 2026.
- Why did my Klaviyo bill suddenly increase?
- Almost certainly the February 2025 billing change. Klaviyo moved from charging on emails sent to charging on active profiles held — meaning every contact capable of receiving email counts, including people who only ever completed a checkout and never opted into marketing. You now pay for profiles whether or not you mail them. Pricing trackers cite bills going from $39 to $200 and $625 to $2,765 in a single cycle. It's why Klaviyo's Trustpilot rating sits at 1.8/5 while G2 and Capterra both sit at 4.6/5 — the product is well liked and the invoice is not.
- Is Omnisend as good as Klaviyo?
- For most stores, close enough to matter. It covers the same core job — Shopify-native flows, email, SMS and push on one plan — at roughly half the entry price, and reviewers rate it well. Where Klaviyo remains genuinely ahead is depth: behavioural segmentation (9.0/10 on G2, the highest-rated part of its profile) and predictive analytics like churn risk and CLV. If your marketing leans on granular behavioural triggers and per-flow revenue attribution, you'll feel the difference. If you run a handful of standard flows and a monthly campaign, you probably won't.
- Is it hard to migrate away from Klaviyo?
- It's the hardest platform on this page to leave, and worth understanding before you commit. Contacts and consent records export cleanly. Sending reputation does not — deliverability is tied to your history on Klaviyo's infrastructure, so a new provider treats you as an unknown sender; budget 2–4 weeks of warm-up and up to eight to fully re-establish at Gmail, Microsoft and Yahoo. Flows and segments are Klaviyo-proprietary and built on its Shopify event model, so they're rebuilt by hand rather than exported. Predictive data — CLV, churn risk, next-order date — does not migrate at all. For a store with dozens of live flows, that's a multi-week project.
- How is AgentCeres different from Klaviyo?
- It isn't a replacement — it's a layer on top, and it's on this page because for some searchers the platform was never the blocker. Klaviyo is an email service provider with best-in-class e-commerce segmentation and revenue attribution: it hosts your profiles, runs your flows, manages deliverability and sends. AgentCeres is a managed AI marketing team that connects to the Klaviyo account you already have; a specialist drafts and clones campaigns, builds segments and writes the content, and sending or scheduling waits for your explicit approval — alongside SEO, social and ads specialists sharing the same product context. It has no sending infrastructure, no flow builder, no predictive analytics and no attribution, and it will not reduce your Klaviyo bill. If the bill is the problem, Omnisend or Brevo are the honest answers.
