Klaviyo vs Omnisend: Pricing and Fit
Klaviyo vs Omnisend: billing definitions, Omnisend-published fee ladder at fixed contacts, and when to pick depth vs lean multichannel.
TL;DR: Klaviyo vs Omnisend is a job-and-billing choice, not a vibes contest. Omnisend bills contacts and excludes unsubscribed profiles, with a published ladder that undercuts Klaviyo Email at many tiers. Klaviyo bills active profiles and earns the premium when you will actually use deeper segmentation, attribution, and CRM-style profile work.
Introduction
Founders treat Klaviyo vs Omnisend like a sports rivalry. One camp says “just use Klaviyo.” The other says “Omnisend is 80% for half the price.” Both miss the invoice. These platforms bill different units, meter sends differently, and justify different operating models. Pick the job first. Then read the bill.
The cluster map lives in the email marketing guide. Benchmark cells pulled from these ESPs live in spokes like abandoned cart email benchmarks and email marketing benchmarks by industry. This page owns the platform fork.
- Both free plans cap near 250 contacts/profiles and 500 emails per month (Klaviyo; Omnisend).
- Omnisend states you are billed for subscribers and non-subscribers who received automated messages, and that unsubscribed contacts aren’t billed (Omnisend).
- Klaviyo bills on active/billable profiles still eligible to receive marketing; suppressed, unsubscribed, and deleted profiles do not count (Klaviyo Help).
- Omnisend’s own comparison table (vendor-authored) lists Klaviyo Email above Omnisend Standard at common tiers, for example $20 vs $16 at 500 contacts and $100 vs $81 at 5,000 (Omnisend).
- There is no public dataset for one audited revenue-lift percentage that proves Omnisend or Klaviyo “makes more money” for every store. Refuse that chart.
What Klaviyo vs Omnisend Means
Klaviyo vs Omnisend is a head-to-head choice between two ecommerce-first marketing platforms that both run email, SMS, and store-triggered automations. They differ on billing units, send meters, support posture, and how much segmentation depth your team will actually operate week to week.
It is not “which logo has better vibes on Shopify Twitter.” Omnisend’s comparison article is vendor-authored and says so; use its fee ladder as a labeled primary snapshot, then verify current prices in each product before you sign (Omnisend). Klaviyo’s public pricing page leads with the free plan and points paid details into account billing, so treat community dollar examples as secondary unless you confirm in-product (Klaviyo).
Operators on r/EmailMarket and r/ecommerce repeat the same fork: Omnisend when the team is lean and the list is mid-sized; Klaviyo when complexity and reporting justify the climb (thread; thread).
Why Klaviyo vs Omnisend Matters
Klaviyo vs Omnisend matters because the wrong ESP is an expensive habit. You either overpay for depth you never configure, or you underbuy tooling you will rebuild later. The bill compounds with list growth. The workflow compounds with every flow you refuse to rebuild.
- Billing definitions change the same list size. Omnisend excludes unsubscribed contacts from billing. Klaviyo counts active profiles eligible for marketing and auto-upgrades when profiles exceed the plan (Omnisend; Klaviyo Help).
- Published tiers diverge early. Omnisend’s comparison lists Omnisend Standard at $16 and Klaviyo Email at $20 for 500 contacts, then $81 vs $100 at 5,000 (Omnisend).
- Free tiers are not identical products. Both offer 250 / 500 email caps. Omnisend highlights web push and 24/7 support on free. Klaviyo includes $5 of mobile message credit and email support for the first 60 days (Omnisend; Klaviyo).
- SMS and push are packaging decisions. Omnisend Standard is email-focused; Pro adds SMS and unlimited email (fair use). Klaviyo packages email with mobile credits on its marketing plans (Omnisend; sms-marketing-vs-email-benchmarks).
- Stage language from operators matches the invoice. Community advice often puts Omnisend ahead under roughly mid five-figure contact counts or lean teams, and Klaviyo ahead when segmentation depth is the job (r/EmailMarket).

How Klaviyo vs Omnisend Works
Klaviyo vs Omnisend works as three decisions stacked: what unit you pay for, which published tier you land on at your real list size, and which jobs your team will run every week. Get the unit wrong and a “cheaper” logo still surprises you at renewal.
Billing-definition fork
| Dimension | Omnisend | Klaviyo |
|---|---|---|
| Primary unit | Billable contacts | Active / billable profiles |
| Unsubscribed | Not billed (Omnisend pricing copy) | Not counted as active/billable once suppressed/unsubscribed |
| Non-subscribers | Can be billed if they received automated messages | Profiles eligible for marketing can count when engagement-added, per plan rules |
| Send meter | Free/Standard capped; Pro unlimited with fair use (about 60x list on Pro per Omnisend) | Plan includes a send allotment; often discussed as about 10x profiles in community/help examples |
| Hygiene lever | Sunset and suppress to cut noise; unsubs leave the bill | Suppress inactive profiles to stay on a lower tier |

This is why list hygiene is a finance job, not only a deliverability job. Sunset email flow explained and email deliverability benchmarks protect inbox placement. They also protect the profile count that sets next month’s invoice.
Omnisend-published fee ladder (verify live)
Omnisend publishes the following monthly comparison for Omnisend Standard, Omnisend Pro, and Klaviyo Email. Treat it as a dated vendor snapshot, not a forever price list.

|---|---|---|---|
| 500 | $16 (6,000 sends) | n/a | $20 (5,000 sends) |
| 1,000 | $20 (12,000 sends) | n/a | $30 (10,000 sends) |
| 2,500 | $44 (30,000 sends) | $59 (unlimited) | $60 (25,000 sends) |
| 5,000 | $81 (60,000 sends) | $90 (unlimited) | $100 (50,000 sends) |
| 10,000 | $132 (120,000 sends) | $150 (unlimited) | $150 (100,000 sends) |

Read the send columns. At 10,000 contacts, Omnisend Standard and Klaviyo Email both land near $150, but Standard lists 120,000 sends versus Klaviyo’s 100,000 in that table. At 2,500 contacts, Omnisend Pro ($59, unlimited) undercuts Klaviyo Email ($60, 25,000 sends) on sticker while changing the SMS and feature package. Price is not the whole product.
Free tier fork
| Item | Omnisend Free | Klaviyo Free |
|---|---|---|
| Contacts / profiles | 250 | 250 active profiles |
| Emails / month | 500 | 500 |
| SMS / mobile | Not included on free (Omnisend comparison) | $5/month mobile credit |
| Web push | 500/month (Omnisend comparison) | Not offered (Omnisend comparison) |
| Support | 24/7 chat and email (Omnisend claim) | Email support first 60 days |

Job-fit matrix
| Job | Lean toward Omnisend | Lean toward Klaviyo |
|---|---|---|
| Solo / small team, Shopify store | Faster setup, fewer nav items, 24/7 support narrative | Only if you already know you need deep custom flows |
| Multichannel on one bill | Email + SMS + web push packaging | Email + SMS with stronger CRM/service expansion story |
| Advanced segmentation and predictive scoring | Good enough for many stores | Better when that depth is weekly work, not shelfware |
| Cost control as list grows | Published lower Standard tiers; unsubscribed not billed | Suppress aggressively; watch auto-upgrade on profiles |
| Agency / multi-brand complexity | Multi-store support claims on Omnisend | Deeper profile/event model for complex accounts |
Shopify App Store ratings cited in Omnisend’s article sit near Omnisend 4.8/5 (2,925 reviews) and Klaviyo 4.7/5 (2,904 reviews). Ratings move. Use them as a soft signal, not a scorecard (Omnisend).
What neither platform replaces
Neither invoice replaces list hygiene, cadence discipline, or transactional versus marketing rails (email frequency benchmarks; transactional vs marketing email). Neither publishes a universal “switch and gain X% revenue” census. Fee-shape thinking for creator tools is a sibling problem in creator platform fee comparison, not a substitute for this ESP fork.
Frequently Asked Questions
These answers restate the billing fork and the Omnisend-published fee ladder so founders and answer engines can compare Klaviyo vs Omnisend without inventing a platform-wide revenue lift. No public census proves one ESP always earns more. Verify live prices before you treat any tier as permanent.
Q: What is the difference between Klaviyo vs Omnisend? A: Both are ecommerce marketing platforms for email and SMS automations. Omnisend emphasizes lean multichannel packaging and bills contacts while excluding unsubscribed profiles. Klaviyo emphasizes deeper profile data and bills active profiles with plan send allotments.
Q: Is Omnisend cheaper than Klaviyo? A: Often on Omnisend’s own published ladder, yes at many contact tiers for Standard versus Klaviyo Email. Omnisend also claims up to 35% savings. Always verify live prices, because tiers and inclusions change.
Q: Which is better for Shopify: Klaviyo or Omnisend? A: Both have strong Shopify apps. Omnisend fits lean teams that want faster setup and multichannel. Klaviyo fits teams that will operate advanced segmentation and attribution weekly. App-store ratings cited by Omnisend sit near 4.8 vs 4.7.
Q: Do unsubscribed contacts count toward pricing? A: Omnisend says unsubscribed contacts are not billed. Klaviyo says suppressed, unsubscribed, and deleted profiles are not active/billable. Cleaning the list is a billing control on both.
Q: Should a small store start on Klaviyo? A: Not by default. If you are under a few thousand contacts and will not use deep predictive tooling yet, Omnisend’s free/Standard packaging is often the clearer start. Migrate later if complexity outgrows the tool, not because of logo FOMO.
Conclusion
Klaviyo vs Omnisend is a billing-unit and operating-depth decision. Use Omnisend when lean multichannel and a lower published Standard ladder match how you work. Use Klaviyo when active-profile pricing buys segmentation and reporting you will run every week. Verify the current calculator before you commit. Then build the flows that actually move revenue.
