Klaviyo vs Omnisend vs Mailchimp Pricing

Compare Klaviyo, Omnisend, and Mailchimp at the same list size. Normalize who counts on the bill, then read free caps, send meters, and published tiers.

TL;DR: Klaviyo vs Omnisend vs Mailchimp pricing only works after you normalize who counts on the bill. Mailchimp bills subscribed + unsubscribed + non-subscribed until you archive, clean, or delete. Omnisend excludes unsubscribed. Klaviyo bills active profiles. Same headcount, three invoices.

Introduction

Founders paste how do Klaviyo’s pricing tiers compare to Omnisend and Mailchimp at the same list size into a spreadsheet and still misread the bill. The sticker is not the list. Each ESP counts a different person as “on plan.”

If you skip that fork, you will crown the cheapest logo while carrying ghosts Mailchimp still invoices—or overpay Klaviyo for depth you never configure.

Key takeaways:

  • Normalize billing units before you compare dollars. Pairwise depth lives on Mailchimp vs Klaviyo and Klaviyo vs Omnisend. This page owns the three-way same-list stack.
  • Mailchimp includes subscribed, unsubscribed, and non-subscribed contacts; archived, cleaned, and deleted drop out (Mailchimp Help). Peak contact total drives the paid bill—detail on how Mailchimp calculates billable contacts.
  • Omnisend bills subscribers and non-subscribers who received automations; unsubscribed contacts aren’t billed (Omnisend).
  • Klaviyo bills active profiles still eligible for marketing; suppressed, unsubscribed, and deleted profiles do not count (Klaviyo Help).
  • There is no public dataset that proves one ESP always produces a higher storewide revenue lift. Refuse that chart.

What Same-List ESP Pricing Means

Same-list ESP pricing means comparing Klaviyo, Omnisend, and Mailchimp after you fix a contact/profile headcount and state which statuses each vendor still bills—then reading free caps, send meters, and published plan stickers.

That one sentence is the definition. “Same list size” is a research method, not a marketing slogan.

On Reddit, ecommerce operators ask whether Klaviyo is “worth it” past ~25k contacts or whether Omnisend covers abandoned cart and post-purchase without the climb (r/Emailmarketing). Early DTC threads often call Klaviyo overkill under ~$30k/month when three flows do the work (r/Emailmarketing). Those debates go sideways when the spreadsheet treats Mailchimp’s contact total like Omnisend’s billable contacts.

Why Billing Units Matter More Than Logos

Billing units matter because list growth compounds the wrong meter. You either overpay for depth you never open, or you underbuy tooling you will rebuild later.

Why founders get the three-way wrong:

  1. Unsubscribes are not free on every ESP. Mailchimp still counts them until archive, clean, or delete (Mailchimp Help). Omnisend’s pricing copy says unsubscribed contacts aren’t billed (Omnisend). Klaviyo drops suppressed/unsubscribed profiles from the active count (Klaviyo Help).
  2. Send ceilings ride different formulas. Mailchimp publishes Essentials 10×, Standard 12×, Premium 15× the contact limit (Mailchimp Help). Omnisend Standard uses 12× list size; Pro is unlimited with fair-use language near 60× (Omnisend). Klaviyo email allotments are commonly discussed near 10× profiles—verify in-account (Klaviyo Help).
  3. Free tiers look identical and are not. All three advertise about 250 contacts/profiles and 500 emails/month. Klaviyo adds $5 mobile credit and limits full email support to the first 60 days on free (Klaviyo). Mailchimp Free adds a 250/day send cap and pauses live/test sends if you exceed 250 contacts (Mailchimp Help).
  4. Vendor ladders need labels. Omnisend’s comparison table is vendor-authored. Use it as a dated snapshot for Omnisend Standard vs Klaviyo Email, then re-check live calculators before you sign (Omnisend).
  5. No universal ROI census. Strategy and flows usually beat the logo at small volume—community consensus, not a feat. study (r/Emailmarketing).

How Klaviyo vs Omnisend vs Mailchimp Pricing Works

Three-way pricing works as a stack: fix the headcount, map who still bills, read free caps, then compare published paid tiers and send meters. Skip a layer and you are comparing different products that share a contact number.

Step 1 — The Same-List Three-Way Billing Stack

Layer Mailchimp Omnisend Klaviyo
Primary unit Contact total across audiences Billable contacts Active / billable profiles
Unsubscribed Still counted until archive/clean/delete Not billed Not active/billable once suppressed/unsubscribed
Non-subscribed / ghosts Count toward contact total Can bill if they received automations Profiles eligible for marketing can count per plan rules
Hygiene lever Archive, clean, delete, sunset Sunset/suppress; unsubs leave the bill Suppress inactive profiles to hold the tier

Step 2 — Free tier at ~250 headcount

Meter Mailchimp Free Omnisend Free Klaviyo Free
Contacts / profiles 250 250 250 active profiles
Email sends / month 500 (daily 250) 500 500
Exceed contact cap Live/test sends held until upgrade or reduce Upgrade path Sending restricted until upgrade
Notable extra Limited templates / 1 audience Multichannel packaging on free (per Omnisend) $5/mo mobile credit; email support 60 days

Step 3 — Published paid stickers at fixed bands

Quotable table first. Omnisend Standard vs Klaviyo Email dollars come from Omnisend’s vendor comparison (label it). Mailchimp mid-tier dollars are calculator-gated on the official UI—use starting anchors here, then verify the live calculator for your exact band.

Fixed band (contacts/profiles) Omnisend Standard (vendor table) Klaviyo Email (vendor table) Mailchimp (official anchors / meters)
500 $16 (6,000 sends) $20 (5,000 sends) Essentials from $13 / Standard from $20; Essentials 10× / Standard 12× sends
2,500 $44 (30,000) · Pro $59 unlimited $60 (25,000) Verify calculator; send = plan × contact limit
5,000 $81 (60,000) · Pro $90 $100 (50,000) Verify calculator; Standard 12× → 60,000 sends at 5,000 limit
10,000 $132 (120,000) · Pro $150 $150 (100,000) Premium base includes 10,000 contacts from $350; Standard calculator for non-Premium

Read the send columns. At 10,000, Omnisend Standard lists 120,000 sends versus Klaviyo’s 100,000 in that table while both land near $150. Price is not the whole product—SMS packaging, Shopify depth, and who still sits on the bill decide the real monthly total.

Treat Omnisend’s ladder as a labeled primary snapshot for Omnisend versus Klaviyo only. Mailchimp’s mid-tier dollars move with the official calculator and with whether your “5,000” tab still includes unsubscribed and non-subscribed contacts. If those ghosts are 20% of the file, Mailchimp is pricing a different list than the one you exported for Omnisend.

Step 4 — Job-fit matrix

Your job Lean pick Why
General ESP / infrequent campaigns Mailchimp Broad suite; watch unsub + non-subscribed inflation on the contact total
Ecommerce email + SMS on one lean bill Omnisend Published Standard ladder undercuts Klaviyo Email at many bands; unsubs leave the bill
Deep Shopify segmentation / predictive flows you will run weekly Klaviyo Active-profile pricing buys depth—only if you use it
List hygiene as a billing control All three Mailchimp: archive/clean; Omnisend/Klaviyo: suppress/sunset (sunset flow)

How to Compare the Three at Your List Size

  1. Export a status breakdown. Count subscribed, unsubscribed, non-subscribed/suppressed separately. That is your true same-list input.
  2. Map each ESP’s billable unit. Apply the billing stack table. Mailchimp’s invoice may exceed “subscribed only.”
  3. Price free first if under 250. Confirm the 500-send cap and extras (Klaviyo mobile credit; Mailchimp daily 250).
  4. Run live calculators at one fixed band. Use Omnisend’s published ladder as a labeled Omnisend/Klaviyo snapshot; open Mailchimp’s pricing calculator for your exact Standard/Essentials tier.
  5. Pick the job, not the logo. If you sell through creators as well as email, list the product on feat..

Frequently Asked Questions

Q: How do Klaviyo’s pricing tiers compare to Omnisend and Mailchimp at the same list size? A: First normalize who counts. Omnisend’s vendor table puts Standard below Klaviyo Email at many bands (for example $16 vs $20 at 500 and $81 vs $100 at 5,000). Mailchimp’s paid stickers are calculator-based; Essentials starts from $13 and Standard from $20, with 10×/12×/15× send multipliers. Re-check live prices before you sign.

Q: Which ESP is cheapest at 5,000 contacts? A: On Omnisend’s published ladder, Omnisend Standard at $81 undercuts Klaviyo Email at $100. Mailchimp Standard at that band requires the live calculator—do not invent a third-party census. Cheapest sticker still loses if Mailchimp’s contact total includes more statuses than your “5,000 subscribers” tab.

Q: Do unsubscribed contacts count toward pricing? A: Mailchimp: yes, until you archive, clean, or delete. Omnisend: pricing copy says unsubscribed aren’t billed. Klaviyo: suppressed/unsubscribed profiles are not active/billable. Cleaning the list is a billing control on every stack.

Q: Are the free plans the same? A: All three sit near 250 contacts/profiles and 500 emails per month. Differences matter: Mailchimp’s daily 250 send cap and send hold on overage; Klaviyo’s $5 mobile credit and 60-day email support window on free. Read the free-tier table before you “start free” as a strategy.

Q: Should every Shopify store default to Klaviyo? A: No. If you will not run deep predictive segmentation weekly, Omnisend’s lean multichannel packaging or a disciplined Mailchimp setup can be the clearer invoice. Migrate when complexity outgrows the tool—not because of logo FOMO. There is no public dataset proving one ESP always wins on revenue.
