Klaviyo vs Omnisend: real pricing, compared

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.

Fit

Choose Klaviyo, or choose Omnisend

Choose Klaviyo if
  • You want the larger ecommerce integration and agency ecosystem of the two.
  • You would rather budget against one stable list price than a promo that reverts after 3 months.
  • Your list is small enough for the free plan and you want an email specialist as you grow.
Choose Omnisend if
  • You want SMS bundled with email on the same contact ladder.
  • You want a genuinely unlimited email-send tier: Omnisend Pro is unlimited from 3,500 contacts up.
  • You are comfortable prepaying 3 months to get the promo rate, and budgeting for list price after it lapses.

Mechanics

How each one actually prices

Klaviyo: one plan, one axis, no promo
A single plan, priced on active-profile brackets with roughly 10x that many sends included. Klaviyo publishes no self-serve promotional pricing.
Omnisend: two plans, a real promo, and a real list price
Standard and Pro each have a verified 3-month-prepay promo tier (what omnisend.com shows by default) and a separate list-price tier, derived from Omnisend's own published entry price. This page always compares the list tier.
Send allowances, side by side
At 10,000 contacts, Klaviyo includes 100,000 sends/mo. Omnisend Standard includes a numeric allowance at the same size; Omnisend Pro is unlimited from 3,500 contacts up, which is why it can cost more per month while never metering sends at all.
Verified differences

What is actually different, not marketing copy

Unlimited sends exist on one of these ladders
Omnisend Pro is the only plan of the two vendors with a published unlimited-send tier, and only from 3,500 contacts up. Klaviyo has no unlimited tier at any contact count; its allowance always scales with contacts.
Promotional pricing exists on one of these ladders
Omnisend publishes a real, verified 3-month-prepay promo (30% off, first upgrade only, once per account). Klaviyo publishes none in our data.
Free plan
Both publish a free plan at 250 contacts and roughly 500 sends/mo.
Read the fine print

Billing traps worth knowing before you commit

Omnisend's headline price is not what you pay long-term
The price shown by default on omnisend.com is a 3-month-prepay promo, first upgrade only, once per account. After that window, the bill reverts to the list price shown on this page, roughly 30% higher.
Klaviyo auto-upgrades you across bracket lines
There is no published way to stay on a cheaper bracket once your profile count crosses its ceiling; the account moves to the next tier automatically.
Omnisend Pro's "unlimited" has a floor
Unlimited sends on Pro only take effect at 3,500 contacts and above. Below that, Pro's included-sends figure is not published in our data, so budget assuming it is not unlimited until you cross that line.
Best fit

By merchant type

Very small list, under 250 contacts
Either free plan works; there is no price difference to argue about yet.
Wants SMS and email on one ladder
Omnisend is the closer match; Klaviyo separates SMS from this email plan entirely.
High-frequency sender past 3,500 contacts
Omnisend Pro's unlimited tier removes the send-volume question; Klaviyo's allowance keeps scaling with contacts either way.
Wants one stable number to budget against
Klaviyo's list price is the number you actually pay from day one; Omnisend's list price only arrives after the 3-month promo lapses.

Methodology

How this page was built

Every price above comes from each vendor's own published, list-basis pricing (never a promotional price), matched to the exact billing interval requested. Omnisend's promotional price is shown once, labelled, and never used to decide which vendor is cheaper. Nothing here is extrapolated beyond either vendor's own published ladder.

FAQ

Frequently Asked Questions

Is Klaviyo or Omnisend cheaper?

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.

Why is Omnisend's price on this page higher than the price on omnisend.com?

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.

Does Omnisend include SMS in this price?

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.

How was this page's pricing checked?

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.
