The 6 best Klaviyo alternatives in 2026

Klaviyo is a serious tool. Its e-commerce automation is among the best available, its Shopify integration runs deep, and its behavioral segmentation gives DTC brands real control over who gets what message and when. That's not the argument here.

The argument is that Klaviyo is not the right foundation for every business. Since February 2025, its active-profile billing change has increased costs for thousands of businesses, some by 25%, without any new capabilities to justify it. And even at the right price, Klaviyo is built around email, SMS in select markets, and push notifications. It has no native WhatsApp support, no Instagram DM, and no infrastructure for AI-driven two-way conversations.

For businesses whose customers primarily communicate through messaging apps, that gap is structural, not cosmetic.

Why look for a Klaviyo alternative?

Three issues come up consistently in conversations about switching.

1. Pricing that scales against you 

Before February 2025, Klaviyo billed based on the profiles you actively emailed each month. A store with 20,000 contacts but only emailing 8,000 of them paid based on that 8,000. The active-profile billing change removed that distinction: now that store pays for all 20,000. The shift raised bills for many businesses by up to 25%, with no new features attached.

At 10,000 contacts, Klaviyo's email-only plan runs $150 per month. At 50,000 contacts, it reaches approximately $720 per month. Add SMS credits on top of that, billed separately by volume.

2. Limited channel coverage

Klaviyo covers email, SMS in select markets, and mobile push. WhatsApp, the world's most-used messaging platform with 3 billion monthly active users, is not in the mix. Neither is Instagram DM or Facebook Messenger. Research from messaging platform Braze puts WhatsApp business message read rates at 68% on average, compared to email's roughly 21% open rate. That gap is worth taking seriously.

3. Architecture built for broadcasts, not conversations

Klaviyo excels at one-to-many outbound campaigns: trigger an email, recover an abandoned cart, send a post-purchase flow. It's a weaker fit for businesses that need to qualify leads in chat, handle two-way conversations at scale, or route a thread from an AI agent to a human sales rep without losing context.

Where Klaviyo is still the right call

If your store runs on Shopify, your customers are email-responsive, and your list is large enough to benefit from Klaviyo's predictive analytics and segmentation depth, the cost is likely justified. Switching for price alone often trades a feature-rich tool for a cheaper one with real capability gaps. Start with the channel question.

1. Omnisend: best for e-commerce email and SMS

Omnisend is built for e-commerce brands that want to run email and SMS from a single platform without the complexity or cost of a larger system. Its pre-built automation library covers the workflows DTC brands use most often: cart abandonment, post-purchase sequences, welcome flows, and product review requests. Tight integrations with Shopify, WooCommerce, and BigCommerce mean setup time is short.

Key features:

• Pre-built e-commerce automation workflows for cart recovery, post-purchase, and browse abandonment

• SMS campaigns alongside email in unified flows

• Product picker widget: pull products directly into email templates from your store

• Shopify, WooCommerce, and BigCommerce integrations

• Behavioral segmentation based on purchase history and on-site activity

• Web push notifications

Pricing: Free plan includes up to 500 contacts and 500 emails per month. Standard plan starts at $16 per month for up to 500 contacts, scaling by contact tier.

Pros: Strong e-commerce workflow library. Competitive pricing vs. Klaviyo at equivalent contact tiers, with Omnisend typically running $10 to $35 cheaper per month across common list sizes. Shopify integration is genuinely close to Klaviyo in depth.

Cons: No WhatsApp. No AI agents. Predictive analytics and advanced segmentation depth are below Klaviyo's level. Not suited for service businesses or any use case centered on messaging channels.

Best for: E-commerce brands that want Klaviyo-style email and SMS automation at a lower price, within the same email-first architecture.

2. Brevo: best for multi-channel messaging on a budget

Brevo (formerly Sendinblue) expanded from an email tool into a broader marketing suite that now includes email, SMS, WhatsApp broadcasts, a built-in contact management system with pipeline view, transactional email, and live chat. Its pricing model is send-volume-based rather than contact-count-based, which makes it notably cheaper for businesses with large lists they email infrequently.

Key features:

• Email, SMS, and WhatsApp broadcast campaigns from one interface

• Contact management module with pipeline view

• Transactional email API for product and system notifications

• Marketing automation with behavioral triggers

• Live chat widget for websites

• Free plan: unlimited contacts, 300 email sends per day

Pricing: Free plan with unlimited contacts and 300 emails per day. Paid plans start at $9 per month for 5,000 emails. WhatsApp broadcast capability available on higher-tier plans.

Pros: The cheapest option that combines email with WhatsApp broadcast capability. Send-volume pricing benefits businesses with large but less frequently emailed lists. Contact management module includes a pipeline view that Klaviyo's base plans lack.

Cons: WhatsApp is outbound broadcast only; it does not support two-way conversations or AI agents. E-commerce automation is less specialized than Klaviyo or Omnisend for DTC-specific workflows. WhatsApp is a plan add-on, not a core feature.

Best for: Small to mid-sized businesses that want email plus WhatsApp broadcast capability at a lower cost than Klaviyo.

3. SleekFlow: best for WhatsApp and AI conversation-led sales

SleekFlow approaches customer engagement differently from every other platform on this list. Where Klaviyo and Omnisend are built to push messages out at scale, SleekFlow is built for what happens when a customer messages you back. An AI agent from AgentFlow can qualify the lead, answer product questions, recommend items, and route to a human rep when the conversation calls for it, all inside WhatsApp, Instagram DM, or Facebook Messenger. SleekFlow connects to WhatsApp Business API as an official WhatsApp Business Solution Provider, with full support for two-way messaging, broadcast campaigns, and AI-driven conversation flows.

Key features:

• WhatsApp Business API: official WhatsApp Business Solution Provider with template messages, two-way conversations, and broadcast campaigns

• AgentFlow: build AI agents that qualify leads, handle product questions, and support customers 24/7 across messaging channels

• Multi-channel inbox: WhatsApp, Instagram DM, Facebook Messenger, SMS, and website live chat in one shared workspace

• Broadcast campaigns with audience segmentation across channels

• Flow Builder for no-code automation workflows

• Shopify integration for e-commerce sales through messaging

• HubSpot and Salesforce connectors

• In-chat payment collection via Stripe

Pricing: Free plan available. Paid plans start from $149 per month. Pricing is based on monthly active contacts (MACs). WhatsApp message costs are billed separately based on Meta's per-conversation rates, which vary by country and message type.

Pros: The only purpose-built WhatsApp platform on this list, with full support for two-way conversations and AI agents in addition to broadcast campaigns. Covers WhatsApp, Instagram DM, Facebook Messenger, and SMS from one inbox. AgentFlow is included in the platform, unlike Klaviyo's AI add-on, which starts at $200 per month extra.

Cons: Email marketing is not a core feature; businesses whose primary channel is email will find a stronger match elsewhere on this list. WhatsApp message costs follow Meta's per-message rates and sit outside the platform fee, so it's worth using the WhatsApp pricing calculator to model your expected spend before committing.

Best for: Businesses that sell and support customers primarily over WhatsApp, Instagram DM, and messaging channels, not email.

4. ActiveCampaign: best for marketing automation and contact management

ActiveCampaign occupies a different niche from Klaviyo. Where Klaviyo is built around e-commerce, ActiveCampaign is used primarily by service businesses, B2B companies, and SaaS teams that need advanced automation logic, behavioral triggers, and a built-in sales pipeline. Its visual automation builder is widely regarded as among the most flexible in the mid-market space, with more conditional branching and trigger options than Klaviyo offers at equivalent tiers.

Key features:

• Visual automation builder with conditional logic and multi-step behavioral triggers

• Built-in contact management with pipeline view

• Email campaigns with advanced segmentation

• SMS messaging

• Site and event tracking to trigger automations based on page visits and actions

• 900+ third-party integrations

Pricing: No free plan. Starter plan begins at $15 per month for up to 1,000 contacts. Scales by contact tier.

Pros: More flexible automation logic than Klaviyo at mid-market pricing. Built-in pipeline view. Better fit for service businesses and B2B. No free-plan-to-paid pressure; the 14-day trial covers the full product.

Cons: No WhatsApp. No AI agents. E-commerce automation is less specialized than Klaviyo or Omnisend for cart-specific and DTC workflows. No free plan.

Best for: Service businesses and B2B teams that need complex email automation with a built-in contact management module.

5. MoEngage: best for enterprise multi-channel engagement

MoEngage is an enterprise customer engagement platform for consumer brands that have outgrown mid-market tools. It combines email, SMS, mobile push, in-app messages, WhatsApp, and web push in one system, with an AI layer for journey orchestration and send-time personalization. For a business running millions of contacts across mobile, web, and messaging simultaneously, it's the most technically capable platform on this list.

Key features:

• Email, SMS, mobile push, in-app, web push, and WhatsApp from one platform

• AI-driven journey orchestration and personalized send-time optimization

• Real-time behavioral segmentation

• Shopify, mobile app SDK, and data warehouse integrations

• Predictive analytics and custom reporting dashboards

Pricing: Custom pricing. No publicly listed starting price. No free plan. Request a demo to receive a quote.

Pros: The most complete multi-channel stack on this list, including WhatsApp at scale. Strong analytics for mobile-first consumer brands. Journey orchestration handles complexity that Klaviyo, Omnisend, and Brevo cannot.

Cons: Custom pricing makes budgeting difficult for teams without a procurement process. Requires dedicated setup time and technical resources. Not practical for SMBs or teams without engineering support.

Best for: Enterprise consumer brands running high-volume, multi-channel customer engagement programs across mobile apps, web, and messaging.

6. MailerLite: best for affordable email basics

MailerLite is the practical choice for small businesses and solo operators who need professional email marketing without the cost or complexity of larger platforms. It covers the fundamentals well: drag-and-drop email builder, automation, landing pages, and website pop-ups. Its free plan is one of the most generous available, and it includes a landing page builder, which is a meaningful advantage over Klaviyo, which doesn't offer one.

Key features:

• Drag-and-drop email editor with pre-built templates

• Automation with behavioral triggers

• Landing page builder (not available in Klaviyo)

• Website pop-ups and embedded signup forms

• E-commerce integrations for Shopify and WooCommerce

• Free plan: up to 1,000 subscribers, 12,000 emails per month

Pricing: Free plan for up to 500 contacts and 12,000 emails per month. Growing Business plan starts at $10 per month for 500 contacts with unlimited email sends (or $9 per month on annual billing).

Pros: Generous free tier for a self-serve platform. Includes a landing page builder where Klaviyo has none. Fast to set up, with a clean interface. Strong deliverability record.

Cons: No SMS. No WhatsApp. No AI agents. Automation is basic compared to Klaviyo or ActiveCampaign. Not suited for high-volume e-commerce operations or multi-location businesses.

Best for: Small businesses and independent operators who need reliable, affordable email marketing without extra complexity.

Klaviyo integrations vs. alternatives: what each tool actually connects to

Klaviyo has more than 300 integrations. That number is worth knowing, and also worth contextualizing. Nearly all of Klaviyo's integrations are wired into the e-commerce stack: Shopify apps, DTC loyalty tools, review platforms, and ad networks. That depth matters if your business runs on that infrastructure. If you primarily sell through conversations, the count is beside the point.

The table below groups integrations by category rather than by count. That framing shows the architectural intent of each tool, which is the decision that actually matters.

What this table shows is not a ranking. It shows that Klaviyo's integrations are designed for e-commerce outbound. SleekFlow's are designed for messaging-led sales and support. They're built for different business models, and the right question isn't which has more integrations. It's which connects to the tools and channels your customers actually use.

Klaviyo alternatives pricing comparison

All prices are public list pricing as of June 2026. Verify with each vendor before purchasing.

On WhatsApp message costs: SleekFlow and Brevo charge for WhatsApp messages separately from the platform fee, following Meta's per-message pricing model. Rates vary by country and conversation type (marketing, utility, service). Use SleekFlow's WhatsApp pricing calculator to estimate message costs for your specific markets before committing to a plan.

The real Klaviyo cost driver: Many businesses switching from Klaviyo are not reacting to the sticker price but to the active-profile billing change. A business that previously paid based on its active email audience may now be paying for contacts it hasn't emailed in months. The first practical step before comparing alternatives is auditing your actual Klaviyo active-profile count versus your regular send audience.

How to choose the right Klaviyo alternative

The 6 platforms on this list are not competing for the same buyer. This decision guide maps each one to a real use case.

1. Start with your primary channel

Where do your customers want to hear from you? If it's their inbox, Omnisend, Brevo, ActiveCampaign, and MailerLite all make sense. If they'd rather message you on WhatsApp, Instagram DM, or Messenger, SleekFlow is the purpose-built option. MoEngage handles either at enterprise scale.

2. E-commerce vs. service vs. conversation 

Klaviyo, Omnisend, and MailerLite are designed around e-commerce. ActiveCampaign fits service businesses and B2B teams better. SleekFlow serves both, but through the lens of messaging-led customer relationships rather than outbound campaigns.

3. AI requirements

If you need AI agents that hold full conversations, qualify leads, and transfer to humans in context, SleekFlow's AgentFlow is the only purpose-built option on this list. Klaviyo's Customer Agent AI is a $200 per month add-on focused on customer support, not sales.

4. Billing model match 

Klaviyo and most email tools charge per contact count. SleekFlow charges per monthly active contact plus separate message fees. Brevo charges per email volume rather than contact count, which helps businesses with large but infrequently emailed lists. Match the billing model to how you actually use the platform.

5. Team size and setup time

MailerLite and Omnisend are fast to configure. ActiveCampaign and Klaviyo require more onboarding investment. SleekFlow and MoEngage are most effective with dedicated setup time, particularly when building AI agents and multi-step conversation flows.

6. Geographic expansion. 

If you plan to grow into markets where WhatsApp is the primary business communication channel (Latin America, MENA, Southeast Asia, and increasingly the US), building on a WhatsApp-first platform from the start avoids a painful platform migration later.

Which Klaviyo alternative is right for your business?

Most businesses searching for Klaviyo alternatives are solving one of two problems: the pricing model became more expensive, or the channel mix stopped matching where their customers actually are.

For the pricing problem, Omnisend gives you the closest feature set at a lower price. Brevo gives you more channels for less. MailerLite keeps it simple and affordable for smaller lists.

For the channel problem, the answer follows from where your customers want to engage. Email and SMS: the first three tools solve it. WhatsApp, Instagram DM, and two-way AI conversations: that's a different architecture entirely, and only one tool on this list was built for it.

Start with the channel question. The tool decision follows from that. If your customers prefer messaging over email, those conversations are already happening somewhere. SleekFlow is built to make sure they happen on your terms.
