Both vendors' own published list pricing, run against the same contacts and send volume. Omnisend's own site leads with a 3-month promo; this page shows that price labelled as a promo, next to the list price it reverts to.
Klaviyo checked September 4, 2026, Omnisend checked September 4, 2026. Both vendors set their own prices and can change them any time.
At 10,000 contacts and 40,000 sends/mo. Both figures are list prices; neither vendor's promo is used to decide this.

Scoped to just Klaviyo and Omnisend, so this stays a comparison between the two, not a wider pitch.
The multiplier buttons set sends relative to your contact count (4x means 4 emails a month per contact).
We use the audience number entered above as the billable contact, profile or subscriber count for each platform. Vendors define billable audiences differently, and a real count after migration can differ.

Pricing is not feature equivalence. These estimates show what each platform charges for the workload you entered. Plans can include different automation, segmentation, SMS, support, ecommerce, and other features.
Curious how either compares against OnVoard specifically? Klaviyo vs OnVoard or Omnisend vs OnVoard, or the wider Klaviyo alternatives page, both run the same numbers against OnVoard's Marketing Platform. Comparing more than these two? See every vendor at once in the full pricing calculator.
At 10,000 contacts and 40,000 sends/mo, Omnisend's list price ($132.00/mo, Standard) is below Klaviyo's ($150.00/mo). Omnisend's own site shows a lower number by default; that is a 3-month-prepay promo, not the list price, and it is never what this page compares.
omnisend.com shows the 3-month-prepay promo price by default ($92.40/mo at this workload). It is real, but it only lasts 3 months, applies to a first upgrade only, and reverts to the list price shown on this page afterward. Comparing it against Klaviyo's list price would not be a fair comparison, so this page does not.
Omnisend sells SMS credits alongside its email plans on the same account; the prices on this page are the email plan only, the same scope as Klaviyo's price. We have not independently verified SMS credit pricing for either vendor, so it is out of scope here.
Both ladders were read directly off each vendor's own public pricing page and re-verified independently; see Sources below. Klaviyo was checked September 4, 2026, Omnisend September 4, 2026.
