Klaviyo vs Omnisend (2026)

Pick Omnisend if you run a small or mid-sized store and want the standard ecommerce flows, SMS and web push for less money. Pick Klaviyo if you have a large list, someone who works on email full time, and you will use its predictive data and reporting. Both are built for online stores, both connect to Shopify, WooCommerce and BigCommerce, and both charge by contact.

Omnisend Standard starts at $16 a month for 500 contacts and Pro at $59, from omnisend.com/pricing. Omnisend often shows a discount for the first months, so the price on its page can be lower than the table. Tier prices for Omnisend come from EmailToolTester and SendX. Klaviyo prices come from EmailToolTester’s Klaviyo breakdown. Full Klaviyo tables are on our Klaviyo pricing page.

What each plan lets you send. Omnisend Standard allows 12 times your contact count in emails each month, so 120,000 emails at 10,000 contacts. Pro has no fixed cap, with a fair-use limit of 60 times your list. Klaviyo’s email plan includes a monthly send allowance that grows with the tier.

Who counts as a contact. Klaviyo bills on active profiles: anyone who can receive marketing email, whether you emailed them that month or not. Omnisend bills for subscribers and for non-subscribers who received automated messages, such as a shopper who got an abandoned cart email. Neither charges for unsubscribed contacts. On both, a store that collects many buyers who never opted in can see its count grow faster than its list.

Omnisend pricing in short

Omnisend’s US SMS price starts at $0.009 per message and drops to $0.007 at high volume.

Where Omnisend wins

It costs less at every list size, and the gap grows. At 50,000 contacts Omnisend Standard is about $300 a month cheaper than Klaviyo’s email plan. Its prebuilt workflows cover the ground most stores use: welcome, cart abandonment, product abandonment, order and shipping confirmation, and cross-sell. Email, SMS and web push can sit in the same automation. Support answers around the clock.

Where Klaviyo wins

Its data. Klaviyo predicts each customer’s lifetime value and churn risk, compares your numbers with similar stores, and gives you more ways to slice a segment. It also supports WhatsApp and mobile app push, which matters if you have your own app. For a large store with an email team, those tools can earn back the extra cost.

Which to pick

Small or mid-sized store, one person doing marketing: Omnisend. You get the flows that matter and a smaller bill.

Large store with an email team: Klaviyo. Use the predictive data, or you are paying for it for nothing.

Store with a big list that mostly gets newsletters: check how many of those contacts each tool would bill you for. Both charge more as the list grows. Broadcast, which we make, is self-hosted email marketing for $250 once, sending through Amazon SES at about $0.10 per 1,000 emails, with your subscriber data on your own server. It has no Shopify integration and no cart flows, so it fits newsletters and sequences better than store automation. The pricing calculator compares the costs at your size.
