Klaviyo vs Omnisend
An independent, review-free comparison compiled by the SaaSTracker editorial team. Both products are profiled in full, and neither can pay for placement here.
The short answer
Both sides assessedKlaviyo compared with Omnisend
Both are ecommerce-first with prebuilt cart and post-purchase flows, but Omnisend's Pro plan bundles unlimited email sends and free SMS credits at a fraction of Klaviyo's price at the same list size. Klaviyo wins on data model depth, predictive analytics, API quality, and segmentation power. Take Omnisend if you want the standard ecommerce flows working cheaply and quickly; take Klaviyo when segmentation sophistication and attribution reporting are what you are actually buying.
Omnisend compared with Klaviyo
The core comparison in ecommerce email. Klaviyo has the deeper data model, predictive analytics, a real CDP, and the better API, and it stops billing suppressed profiles. Omnisend gets the standard flows working faster and cheaper, offers unlimited sends on Pro, and gives 24/7 human support on every plan. Take Klaviyo when segmentation sophistication is the purchase reason; take Omnisend when you want the money-making flows live this week without the invoice.
Choose Klaviyo if
Direct-to-consumer and ecommerce brands on Shopify, BigCommerce, or WooCommerce doing enough revenue that abandoned-cart and post-purchase flows pay for the subscription several times over, and who want segmentation driven by purchase behavior rather than by tags they maintain by hand.
Choose Omnisend if
Small and mid-size ecommerce stores on Shopify, WooCommerce, BigCommerce, or Wix that want the standard revenue-producing flows working quickly and cheaply, especially stores that send frequently enough for Pro's unlimited email sending to pay for itself.

| Setup time | An afternoon for a Shopify store to be sending. The store connector installs in one click and backfills order history, the onsite snippet goes on automatically, and the prebuilt flows can be turned on with default content the same day. Getting the flows genuinely good, with branded templates and considered branching, is a two to four week project. | A day to have the core flows running. The store connector installs quickly, syncs products, orders, and customers, and the prebuilt workflows can be enabled with default content immediately. A full migration including domain authentication and testing typically takes around five business days. |
| Learning curve | Moderate and front-loaded. The flow builder and campaign sending are approachable, but segment logic over event properties is where people get stuck, because it asks you to think in terms of events and their metadata rather than in terms of lists. Anyone who has only used tag-based ESPs will need a week to stop fighting the model. | Low, and deliberately so. This is the most approachable serious ecommerce marketing tool in the category. The workflow builder is legible to someone who has never built an automation, and the prebuilt library means most stores never start from a blank canvas. The one thing to understand early is the contact-counting rule, because it determines your bill. |

Strengths and limitations
Klaviyo
Strengths
- The data model is the real product: live segments over order history, browsing behavior, and predicted values give you targeting no tag-based ESP can express.
- Revenue attribution per flow and campaign is credible because Klaviyo already holds the order events, which makes the subscription defensible to whoever signs off on spend.
- Suppressed profiles stop counting toward the bill, so unsubscribes and bounces reduce cost rather than becoming permanent dead weight.
- Prebuilt ecommerce flows mean a new store can have abandoned cart, welcome, browse abandonment, and post-purchase live in days rather than designing automation from a blank canvas.
Limitations
- Expensive at scale. Roughly $720 a month at 50,000 profiles is several times what Brevo, Omnisend, or MailerLite charge for comparable list sizes, and the per-profile rate does not improve as you grow.
- The send allowance of about ten times your profile count constrains high-frequency senders, so a daily-mailing brand can be forced into a higher band by volume rather than by list growth.
- No advertised annual discount on self-serve plans, removing a lever that almost every competitor offers.
- The email editor is functional rather than delightful; teams coming from MailerLite or Kit usually find it a step down aesthetically.
Omnisend
Strengths
- Unlimited email sending on Pro removes the send meter entirely, which is a genuine structural advantage over every contact-plus-send-cap competitor.
- The prebuilt ecommerce workflow library gets abandoned cart, welcome, browse abandonment, and post-purchase live in a day, which is where most of the money in store email actually comes from.
- Cross-channel steps inside a single workflow, so email, SMS, and web push run from one sequence and one consent record rather than parallel automations.
- 24/7 live chat and email support with a real human on every plan including Free, with advertised response times measured in minutes. Nothing else in this category does that.
Limitations
- Billing counts non-subscribers who received automated messages, so guest checkouts and imported contacts without an opt-in date inflate the bill beyond your actual marketing list size.
- SMS credits were removed for new subscriptions on 4 May 2026, making SMS a Pro-only metered add-on and quietly raising the cost of the omnichannel proposition.
- Hitting the Standard send cap blocks campaigns and cancels contacts out of running automation workflows, which breaks live sequences rather than just charging you more.
- No customer data platform, warehouse sync, identity resolution, or predictive lifetime value modelling, so a brand that outgrows the flows will eventually look at Klaviyo anyway.
Pricing compared
Klaviyo
Self-serve tiers priced by active (marketable) profile count, with a monthly email send allowance of roughly ten times the profile count; SMS is sold as a higher Email plus SMS plan with its own message credits, and the newer data, service, and AI product lines meter separately.
- Free$0
- Email (1,000 profiles)Approximately $30
- Email (10,000 profiles)Approximately $150
- Email (50,000 profiles)Approximately $720
- Enterprise and additional product linesQuoted
For a store with real order volume, Klaviyo at 1,000 or 10,000 profiles is straightforwardly good value, because the four standard flows typically return several multiples of the subscription and the attribution report proves it in a currency the founder already thinks in. The suppression policy is a genuine and underrated saving, since you are not paying rent on people who left. Value collapses in two situations: a large list without commerce revenue behind it, where $720 a month at 50,000 profiles buys reporting you cannot monetize, and a business that lets the SMS, reviews, and data product lines accumulate until the email tool costs enterprise money. Judged strictly as ecommerce email, it is expensive and worth it; judged as a general-purpose ESP, it is the wrong shape at the wrong price.

Self-serve tiers priced by contact count, where both subscribers and non-subscribers who received automated messages are billable and only unsubscribed contacts are excluded. Standard caps monthly emails at twelve times the contact count; Pro removes the email send meter entirely. SMS is a separately metered Pro-only add-on for new subscriptions since May 2026.

- CustomQuoted
Omnisend is the value play in ecommerce email and is priced with a clear view of who it is taking customers from. At 10,000 contacts you are looking at roughly $132 on Standard or $150 on Pro against roughly $150 on Klaviyo's Email plan, which is a wash on headline price but not on terms, because Pro carries no send cap while Klaviyo's allowance is ten times your profile count. At 50,000 contacts the same comparison runs roughly $413 or $715 against roughly $720. So the saving is not enormous at the top, and the real argument is unlimited sending plus getting the standard flows working in a day. Two things erode the case: the inclusive contact meter that bills non-subscribers, and the May 2026 removal of bundled SMS credits, which quietly raised the true cost of the omnichannel pitch the product is named for. For a store that mails often and does not need a customer data platform, it remains the best money in this category.
Editorial verdict on each
Klaviyo
Klaviyo is the correct default for an ecommerce brand with enough order volume that automated flows are a revenue line rather than a nice-to-have. The customer database underneath, the live segmentation over purchase and browsing behavior, and the revenue attribution that makes the spend defensible are genuinely a class above what general-purpose ESPs offer, and billing only for marketable profiles is a fairer meter than most of the category uses. The costs are real: no annual discount, a send allowance tied to list size, a per-profile rate that never improves with scale, and a growing set of adjacent products that each want their own line on the invoice. Buy it if a checkout produces your revenue and you intend to run serious flows. Do not buy it for a newsletter, a service business, or a big list with thin margins, where you will pay ecommerce prices for reporting you cannot cash.

Omnisend is the sensible default for a small or mid-size online store that wants the flows that actually make money working quickly, without buying a customer data platform it will not use. The prebuilt workflow library, the cross-channel steps, the capture tooling, and 24/7 human support on every plan including free make it the most approachable serious ecommerce marketing tool in the category, and unlimited email sending on Pro is a real structural advantage over every competitor that caps sends at a multiple of your list. Two caveats deserve weight before you sign: the contact meter counts non-subscribers who received automated messages, which inflates the bill for stores with heavy guest checkout, and the May 2026 removal of bundled SMS credits quietly raised the cost of the omnichannel promise. Buy it if you run a store, mail frequently, and want revenue flows live this week. Look at Klaviyo instead if the reason you are shopping is segmentation depth, and look at MailerLite if your email programme is really just a newsletter.
