Omnisend vs Klaviyo
The two platforms most stores end up choosing between. Klaviyo goes deepest on data and segmentation; Omnisend gets the same eCommerce flows live faster and stays cheaper as your list grows. The right one depends on how much you’ll use the depth you’re paying for.
Omnisend is our Editor’s Choice for most stores: true multichannel (email, SMS and web push in one), prebuilt eCommerce flows that go live fast, a free plan, and gentler contact-based pricing. Klaviyo is the more powerful data platform — the deepest Shopify integration, the best segmentation, predictive analytics — and the better pick once segmentation depth is the whole point and you’ll genuinely use it. Start with Omnisend; reach for Klaviyo when your marketing is data-led at scale.
The short version.
On our benchmark Omnisend takes the higher Index Score (87 to 84) — but that headline hides where each one really pulls ahead.
On platforms, Klaviyo is wider — 5 of 6 versus 4. If the platform your store runs on isn't covered, the rest barely matters.
On price, Omnisend starts lower — from $16/mo against from $20/mo — though the cheaper sticker isn't always the better deal once you factor in what each one includes for the money.
So Omnisend suits smb/startup/mid-market teams; Klaviyo leans toward smb/mid-market/startup/agency.
