Our verdict
Klaviyo is the benchmark for e-commerce email, with the deepest data, the smartest purchase-behavior segments, and revenue reporting per email. Omnisend ships the key store flows prebuilt, combines email with SMS, and is clearly cheaper in the lower tiers. Small and starting stores are better off at Omnisend.
Once your list and revenue grow, Klaviyo earns back its premium. On raw capability, Klaviyo wins.

“Klaviyo power at a friendlier price. You get prebuilt e-commerce flows, email and SMS in one, and a free plan that lets a small store start properly. The smart budget pick for online shops.”Editorial team, on Omnisend
Frequently asked questions
Klaviyo or Omnisend for my online store?
Small and starting stores are better off at Omnisend. The store flows are prebuilt, email and SMS live in one workflow, and the lower tiers are clearly cheaper. Klaviyo earns its premium once your list and revenue grow, with the deepest data, the smartest purchase-behaviour segments and revenue reporting per email. On raw capability, Klaviyo takes it.
How much cheaper is Omnisend than Klaviyo?
At entry level, Omnisend Standard is $16 a month or $192 a year from 500 contacts, against $20 a month or $240 a year for Klaviyo's Email plan from 251 contacts (US dollars, checked August 2026). Both offer a free tier of 250 contacts and 500 emails a month, and both bills climb steeply with list size, so check your own tier before committing.
Does Omnisend do SMS as well as Klaviyo does?
Both put email and SMS in the same flow, so you are not bolting on a second tool either way. Omnisend leans on ready-made flows for abandoned carts, welcome series and win-backs that you can switch on in minutes. Klaviyo builds its SMS into the same behaviour-driven segments as its email, which is what makes it sharper on bigger lists.
Where does Omnisend fall short?
Depth of segmentation. Omnisend does not slice your audience on purchase behaviour as finely as Klaviyo, and Klaviyo's revenue-based reporting tells you what each email actually earned rather than who opened it. For most small and mid-size shops that gap does not justify the price difference, but a store with real data to work with will feel it.
