Omnisend bundles more AI tools into flatter tiers and keeps the learning curve shorter.
Klaviyo‘s entry Email plan starts at $20/month for 251-500 active profiles. Omnisend‘s Standard plan starts around $11.20/month at its lowest contact tier.

Pricing: active profiles vs flat contact tiers
Why the same-size list costs less on one platform than the other.
Bottom line: Klaviyo's Email plan starts at $20/month for 251-500 active profiles with 5,000 emails and 150 mobile messaging credits included, and its pricing moved to an active-profile model in February 2025 that counts engaged contacts rather than total list size. Omnisend bundles channels into flatter tiers: its Standard plan starts around $11.20/month at the lowest contact tier with 6,000 emails included, and its Pro plan runs about $41.30/month for 2,500 contacts with unlimited email sends and bonus SMS credits equal to the monthly bill. At matching contact counts, Omnisend is consistently the cheaper platform, which is the single biggest reason smaller ecommerce stores default to it over Klaviyo.
At the same contact count, Omnisend's Standard plan undercuts Klaviyo's Email plan, and its Pro tier adds unlimited email sends where Klaviyo keeps a send cap tied to profile tier.
AI tools: bundled flat rate vs usage-based credits
Omnisend puts a number on what Klaviyo treats as a consumable.
Bottom line: Omnisend's Pro plan bundles five named AI tools directly into its flat price: Forms AI and Reports AI on every paid tier, plus Dynamic Content, a Personalized Product Recommender, and Personalized Send-Time optimization on Pro. None of these draw down a separate credit balance. Klaviyo's AI features run through its Composer tool, which ships with a monthly usage credit, $5 on the free plan, rather than unlimited access bundled into a flat fee. For a store that wants predictable AI costs regardless of how much content it generates in a given month, Omnisend's model is simpler to budget around.
Integration depth: Klaviyo’s edge for complex stacks
Both cover the major ecommerce platforms. Only one goes much further.
Bottom line: Klaviyo lists more than 350 integrations, including the major ecommerce platforms (Shopify, WooCommerce, Wix, BigCommerce, Magento) plus Salesforce Commerce Cloud for enterprise-grade stacks. Omnisend covers the same core ecommerce platforms, adding Shopify, BigCommerce, WooCommerce, WordPress, Wix, Shoplazza, and Ecwid, but its total integration catalog is narrower than Klaviyo's. For a store running a simple Shopify or WooCommerce setup, this gap rarely matters. For a brand with a more complex tech stack that needs to connect help desk, CRM, or enterprise commerce tools, Klaviyo's broader catalog is the safer long-term bet.
Should I choose Klaviyo or Omnisend?
Bottom line: Klaviyo suits stores that need predictive segmentation and the widest integration catalog; Omnisend suits stores that want strong AI-assisted automation at a lower, flatter price with an easier learning curve.
- Your store depends on deep, predictive segmentation
- You need the widest ecommerce and enterprise integration catalog
- You are comfortable with active-profile pricing that rewards list hygiene
- You want native help desk and omnichannel support features bundled in
- Budget flexibility matters less than data depth
- You want a shorter learning curve for your marketing team
- You want five AI tools bundled into one flat Pro plan
- You want unlimited email sends without a per-send fee on Pro
- Pre-built automation workflows on the free plan matter to you
- You want the cheaper platform at the same contact count
For ecommerce brands that depend on predictive segmentation and the broadest integration catalog, Klaviyo remains the category benchmark, with 350+ integrations and the deepest profile-level targeting in this roundup.
But Omnisend is the right call for most small and midsize stores: it is cheaper at the same contact count, bundles five AI tools into one flat Pro price, and ships pre-built automation even on its free plan.
Before choosing Klaviyo, confirm you will actually use its deeper segmentation and integration catalog, since that is what justifies the higher bill. If your stack is a straightforward Shopify or WooCommerce store, Omnisend is very likely the better value.
The most common questions ecommerce teams ask when choosing between Klaviyo and Omnisend Klaviyo is the better default for stores that depend on deep segmentation and predictive data, scoring 4.7/5 versus Omnisend's 4.5/5. Omnisend is the better pick for small and midsize stores that want an easier learning curve and stronger built-in SMS and web push at a lower price, especially once a store moves past the free tier. Klaviyo's Email plan starts at $20/month for 251-500 active profiles and 5,000 emails. Omnisend's Standard plan starts around $11.20/month for its lowest contact tier with 6,000 emails included, and its Pro plan runs about $41.30/month for 2,500 contacts with unlimited email sends. Both price by profile or contact count, so costs rise together as a list grows, but Omnisend is consistently the cheaper entry point. Yes. Klaviyo's free plan covers up to 250 active profiles and 500 emails a month, with a $5 monthly credit for SMS and its AI-powered Composer tool. Omnisend's free plan covers 250 contacts with up to 500 emails and 500 web push notifications a month. Both free plans are close in size, though Omnisend throws in pre-built automation workflows like welcome series and abandoned cart even at the free tier. Omnisend's Pro plan bundles five AI tools directly into the price: Forms AI, Reports AI, Dynamic Content, a Personalized Product Recommender, and Personalized Send-Time optimization. Klaviyo's AI tools are not bundled the same way into a flat plan; its usage-based Composer credit model means AI content generation draws down a separate monthly credit rather than being an unlimited included feature. Klaviyo lists more integrations overall, with 350+ apps including Shopify, WooCommerce, Wix, BigCommerce, Magento, and Salesforce Commerce Cloud. Omnisend supports all the major ecommerce platforms as well, including Shopify, BigCommerce, WooCommerce, WordPress, Wix, Shoplazza, and Ecwid, but with a narrower total integration catalog than Klaviyo.Frequently asked questions: Klaviyo vs Omnisend
