A store with 10,000 contacts pays 150 dollars a month for Klaviyo Email. The same store pays 132 dollars a month for Omnisend Standard, and 413 dollars a month against 720 dollars once the list reaches 50,000 contacts. That gap is the reason store owners start asking how to switch from Klaviyo to Omnisend, and the math only gets stronger as the list grows.
Klaviyo is the deeper tool. Its segmentation, predictive analytics and product recommendations are the best in this category, and large stores that live on those features rarely leave. Omnisend is the cheaper tool for the same everyday work. It sends the same welcome flow, the same abandoned cart flow and the same post-purchase flow, and it puts email, SMS and web push on one bill. A store that sends five campaigns a month and runs three core flows will notice almost no difference in the inbox, and a large difference in the invoice.
The switch is not about which platform wins awards. It is about which price curve matches the store. Klaviyo charges by active profile, and the bill climbs in steps that feel steep past 10,000 profiles. Omnisend charges by contact, and its Standard plan grows more slowly at every list size from 500 contacts upward. For a store with a growing list and a simple flow setup, the saving is real money every month. For a store that depends on Klaviyo predictive segments and deep Shopify event triggers, the saving can cost more in lost revenue than it saves in fees, and this guide says so plainly.
This guide walks through how to switch from Klaviyo to Omnisend in seven steps, with a cost comparison, a clear account of what transfers, what must be rebuilt, and what to test before cancelling Klaviyo. Follow the steps in order, run both tools side by side for two weeks, and the move will be quiet. Skip the steps, cancel early, and flows, segments and SMS consent can break without warning.
The Bill That Pushes Stores to Look Elsewhere
Cost is the reason most stores switch, and the numbers explain why. Klaviyo has a free plan for up to 250 active profiles, with 500 emails a month and 5 dollars of mobile message credit. The paid Email plan starts at 20 dollars a month for 251 to 500 profiles, with 5,000 sends. At 1,000 profiles it costs 30 dollars a month. At 2,500 it costs 60 dollars. At 5,000 it costs 100 dollars.
At 10,000 profiles Klaviyo costs 150 dollars a month. At 25,000 it costs 400 dollars. At 50,000 it costs 720 dollars. At 100,000 it costs 1,380 dollars. Every step up is a bigger jump than the last, and the bill is driven by active profiles, not by total contacts, so suppressed and unsubscribed profiles do not inflate it.
Omnisend has a free plan for up to 250 contacts, with 500 emails a month and 500 web push notifications. The Standard plan starts at 16 dollars a month for 251 to 500 contacts, with 6,000 sends. At 1,000 contacts it costs 20 dollars a month. At 2,500 it costs 44 dollars. At 5,000 it costs 81 dollars. At 10,000 it costs 132 dollars. At 25,000 it costs 282 dollars. At 50,000 it costs 413 dollars. At 100,000 it costs 900 dollars. Standard allows 12 sends per contact per month, against 10 sends per profile on Klaviyo, so the cheaper plan also allows more email per contact.
Omnisend Pro starts at 59 dollars a month and covers up to 2,500 contacts, with unlimited email under a fair use limit of about 60 sends per contact. At 5,000 contacts Pro costs 90 dollars a month. At 10,000 it costs 150 dollars, the same as Klaviyo Email. At 25,000 it costs 400 dollars, again the same. At 50,000 it costs 715 dollars, against 720 dollars for Klaviyo. Pro adds SMS access, bonus SMS credits equal to the monthly bill, and an account expert once the store pays 400 dollars a month or more. A store that only needs email should compare Standard, not Pro, because Standard is the plan that saves money.
A store with 10,000 contacts saves 18 dollars a month on Standard, or 216 dollars a year. A store with 50,000 contacts saves 307 dollars a month, or 3,684 dollars a year. A store with 100,000 contacts saves 480 dollars a month, or 5,760 dollars a year. Those figures use monthly billing on both tools, before tax, and they are the regular list prices, not the 30 percent introductory discount Omnisend offers for the first three months. The saving grows with the list, which is exactly why growing stores are the ones that switch.

Klaviyo wins on depth. Its predictive analytics, product recommendations, send time optimization and segmentation go further than Omnisend, and a store that builds segments from purchase history and browsing behavior will feel the difference. Omnisend wins on price growth and on breadth at the low end, because it bundles email, SMS and web push into one contact model and one bill. Check which side of that trade the store sits on before moving, because the wrong side costs more than the saving.
What Omnisend Does Differently
A switch guide that only lists the saving is not honest, so this section states the trade plainly. Klaviyo treats the customer profile as the product. Every event, every purchase, every browse and every predicted value feeds one profile, and the segmentation builder can slice that profile in ways Omnisend cannot match. A store that runs twenty segments and ten flows built on predicted lifetime value will rebuild less than half of that logic in Omnisend, and some of it cannot be rebuilt at all.
Omnisend treats the campaign as the product. Its automation library covers the flows a store actually runs, welcome, abandoned cart, abandoned browse, post-purchase, win-back and birthday, and each one is ready to edit in minutes. The builder is simpler, the templates are closer to finished, and the reporting answers the question a small store asks, which is how much revenue this flow made this week. A store that runs three to five core flows will set them up faster in Omnisend than it ever did in Klaviyo.
SMS is the wrinkle to price before deciding. Klaviyo sells SMS as a separate plan from 15 dollars a month, with its own credits. Omnisend changed its SMS rules in 2026, and new customers now need the Pro plan plus a paid SMS subscription from 10 dollars a month, with messages priced from 0.009 dollars down to 0.007 dollars each by volume. A small store that wants both email and SMS can find Omnisend Pro at 59 dollars a month more expensive than Klaviyo Email at 20 dollars plus a 15 dollar SMS plan, which totals 35 dollars. Run the combined bill, not the email bill alone, before choosing.
Support is the quiet difference. Omnisend gives 24/7 live chat and email support on every plan, including the free plan. Klaviyo gives email support for 60 days on the free plan, and the depth of help grows with the spend. A small store that needs an answer at midnight will get one faster from Omnisend, and that is worth real money during a sale week.
How to Switch from Klaviyo to Omnisend in 7 Steps
Step 1. Audit the Klaviyo account before touching anything
Open Klaviyo and list every list, every segment, every flow, every campaign template, every signup form and every SMS keyword. Export the contact lists as CSV files, including the suppression list, and note the renewal date and the billing cycle, because cancelling mid cycle does not refund the month. Pay special attention to flows with conditional splits, flows that use predicted values, and segments built on custom events, because those are the pieces that do not move cleanly. This audit takes an hour and prevents the most common switch failure, which is discovering a revenue flow only after it was deleted.
Step 2. Set up Omnisend and connect the store
Create the Omnisend account, choose the plan that matches the list size, and connect the store through the Shopify integration or the platform connector the store uses. Sync the product catalog and the order history, and confirm the contacts, orders and products land in Omnisend with the right counts. Set the sender name, the reply address and the sending domain, and add the SPF and DKIM records Omnisend provides, because domain authentication decides whether the first campaigns reach the inbox. Do not import contacts yet. A clean connection decided on paper saves a week of fixing later.
Step 3. Import contacts, lists and segments
Import the contact CSV files into Omnisend, mapping email, first name, last name, phone, tags and consent status field by field. Bring the suppression list across first, so no unsubscribed contact ever receives a campaign from the new tool. Rebuild the segments with Omnisend conditions, starting with the ones the store actually mails, engaged subscribers, recent buyers, VIP buyers and cart abandoners. Check the counts against Klaviyo after each import, and fix the mapping before the big import. A pilot import on one list prevents a workspace wide mess.
Step 4. Rebuild the flows in the automation library
Flows do not transfer between platforms, so rebuild them in Omnisend from the automation library. Start with the three flows that earn the most revenue, welcome, abandoned cart and post-purchase, and copy the timing, the discounts and the subject lines from Klaviyo. Rebuild the email templates inside Omnisend, because Klaviyo templates cannot be imported as editable designs. Test each flow with a test contact before turning it on, and check that the discount codes and product blocks pull the right products. This is the largest single task in the switch, so budget a full afternoon for a normal store.
Step 5. Move the signup forms and SMS consent
Replace the Klaviyo signup forms on the store with Omnisend forms, and check that the welcome flow triggers from the new form on the first submission. SMS consent needs special care, because consent collected in Klaviyo does not automatically carry the same proof into Omnisend, and texting a contact without clear consent risks complaints and carrier blocks. Confirm the consent records, the keywords and the opt-out handling in Omnisend before sending a single SMS. A store that texts without clean consent will pay for it in deliverability.
Step 6. Run both tools side by side for two weeks
Send campaigns from Omnisend for two weeks while Klaviyo stays open and the old flows finish. Watch the open rates, the click rates and the revenue per campaign daily, and compare them with the Klaviyo numbers from the same weeks last month. Confirm the flows fire on time, the discount codes work, and the segments update after each order. Fix the problems while Klaviyo is still available as a fallback, not after it is cancelled. Two quiet weeks of parallel running cost nothing and catch every problem early.
Step 7. Cancel Klaviyo and confirm the data is safe
Once two weeks of Omnisend campaigns look clean, export the final contact lists, flow performance reports and campaign history from Klaviyo, then cancel the subscription before the renewal date. Confirm the cancellation email arrives, and check that no auto renewal is set. Keep the Klaviyo export files for six months, because the flows and segments cannot be re-imported later and the old exports are the only record of what the store used to send. The switch is done when Omnisend has run cleanly for two weeks and Klaviyo is cancelled without a surprise charge.
What Moves Across and What You Rebuild
Contacts, lists and the suppression list move well. Export them as CSV files from Klaviyo and import them into Omnisend with the fields mapped, and the store keeps its audience intact. Order history and product data sync through the store integration, so revenue attribution and product blocks work from day one. Segments move as logic, not as files, and each one must be rebuilt with Omnisend conditions, which cover the common cases, engaged, recent buyer, VIP, cart abandoner, and leave the predictive cases behind.
What does not transfer is specific, and the store should name it before starting. Flows do not transfer, so every welcome, cart, browse and post-purchase flow must be rebuilt in the automation library. Email templates do not transfer as editable designs, so each template must be rebuilt in the Omnisend editor. Signup forms do not transfer, so each form must be rebuilt and placed on the store again. SMS consent records need verification, and a store should confirm the consent proof before texting anyone from Omnisend.
Predictive analytics do not transfer. Klaviyo predicted lifetime value, churn risk and next order date have no direct match in Omnisend, so segments built on those values must be replaced with behavior segments built on recency, frequency and spend. Custom events and metrics need mapping too, because an event name in Klaviyo may not exist in Omnisend until the store integration creates it. The only things lost are the Klaviyo specific records, which are the flows, the templates, the forms and the predictions. Export them all before cancelling, and the switch loses nothing that matters.
That is the full picture of how to switch from Klaviyo to Omnisend without losing the audience that matters.
The Go-Live Checklist
Use this checklist before starting step 1, and do not skip a line.
- List every Klaviyo list, segment, flow, template, form and SMS keyword. – Export every contact list as a CSV file and save the files. – Export the suppression list first, and import it into Omnisend first. – Note the Klaviyo renewal date and any contract term. – Flag flows with conditional splits and segments built on predicted values. – Choose the Omnisend plan by list size and by SMS need.
- List the Klaviyo flows, templates and forms the store actually uses. – Confirm the sending domain, SPF and DKIM records in Omnisend. – Plan a replacement for any Klaviyo feature Omnisend lacks. – Set a switch date in a quiet week, not during a sale. – Tell the team the switch date and the new workflow before step 1.
What the Switch Saves in Real Money
The saving depends on list size, because the two tools charge different rates for the same contacts. A store with 500 contacts pays 20 dollars a month on Klaviyo Email against 16 dollars on Omnisend Standard, a saving of 4 dollars a month or 48 dollars a year. A store with 2,500 contacts pays 60 dollars a month on Klaviyo against 44 dollars on Omnisend Standard, a saving of 16 dollars a month or 192 dollars a year. A store with 5,000 contacts pays 100 dollars against 81 dollars, a saving of 19 dollars a month or 228 dollars a year.
A store with 10,000 contacts pays 150 dollars a month on Klaviyo against 132 dollars on Omnisend Standard, a saving of 18 dollars a month or 216 dollars a year. A store with 25,000 contacts pays 400 dollars against 282 dollars, a saving of 118 dollars a month or 1,416 dollars a year. A store with 50,000 contacts pays 720 dollars against 413 dollars, a saving of 307 dollars a month or 3,684 dollars a year. Those figures use monthly billing on both tools, and annual billing does not change the comparison much, since neither vendor publishes a large annual discount on these plans.
The saving shrinks when the store adds SMS. Omnisend Pro at 59 dollars a month for up to 2,500 contacts plus a 10 dollar SMS subscription totals 69 dollars, against Klaviyo Email at 60 dollars plus a 15 dollar SMS plan, which totals 75 dollars, so Omnisend still wins by 6 dollars at that size. At 500 contacts, Omnisend Pro at 59 dollars plus 10 dollars totals 69 dollars, against Klaviyo at 20 dollars plus 15 dollars, which totals 35 dollars, so Klaviyo wins by 34 dollars for a small SMS sender. Count the SMS volume and run the combined totals, because the email saving alone can mislead a store that texts heavily.
Run the same math for your own list before you commit to how to switch from Klaviyo to Omnisend, because the totals decide the plan.
Your First Two Weeks on Omnisend
The parallel run only helps if the store tests the right things, so set the tests before the first Omnisend campaign is sent. Send one campaign to the engaged segment, trigger one welcome flow with a test signup, and abandon one test cart to confirm the cart flow fires with the right products and the right discount. Then compare the Omnisend revenue per campaign against the Klaviyo numbers from the same weeks last month, checking totals by flow and by segment. That test plan is the part of how to switch from Klaviyo to Omnisend that most stores skip, and it is the part that catches the problems while Klaviyo is still available as a fallback.
Test the deliverability and the forms next, because those are the pieces that break quietly. Confirm the first campaigns land in the inbox, not the spam folder, and check the sender domain authentication in Omnisend after the first send. Submit the new signup form on the live store and confirm the welcome email arrives within minutes. Also test one SMS to a consenting test contact, since SMS consent and carrier filtering trip up stores that assume texting works the same on both tools. A test that covers campaigns, flows, forms and SMS in the first week leaves the second week for fixing what failed, which is exactly how a quiet switch is supposed to work.
Five Mistakes That Stall the Move
The first mistake is cancelling Klaviyo before the Omnisend flows are checked. A store that cancels on day one loses the flow history, the template designs and the segment logic in one move, and the rebuild takes days instead of hours. Keep Klaviyo until step 7, and the switch stays boring. The second mistake is importing contacts without the suppression list. A single campaign to an unsubscribed contact creates complaints that hurt deliverability for months, and the fix costs more than the import ever did.
The third mistake is forgetting SMS. A store that texts from Klaviyo and assumes the same consent and pricing carry over will see the Omnisend bill rise by the Pro plan and the SMS subscription, and a store with a large SMS list can add dozens of dollars a month it did not budget. Price the combined email and SMS bill before choosing a plan. The fourth mistake is skipping the two week parallel run. A store that switches overnight discovers the flow gaps during a live sale, when fixing them costs the most. Two quiet weeks of parallel running cost nothing and catch every problem early.
The fifth mistake is underestimating the template rebuild. Email templates do not transfer as editable designs, and a store that budgets an hour for the rebuild will run out of time. Budget an afternoon, rebuild the top three flows first, and leave the long tail of old campaign templates behind. The switch is a good time to clean the template library, not a reason to move every old design into the new tool.
Life After the Switch
The first month after the move is when the saving becomes real, and it is also when the new habits form. Set a weekly review in Omnisend, one hour where the store checks flow revenue, clears the suppression list and updates the segments, because a cheaper tool still needs a steady rhythm to earn its keep. Tune the rebuilt flows after two weeks, not on day one, because the first fortnight shows which flows fire too often and which never fire at all. The work of how to switch from Klaviyo to Omnisend does not end on cancel day. It ends when the store stops opening the old tool out of habit, and that usually takes a full month.
Revisit the plan choice after 90 days. A store that started on Standard may find it needs Pro for unlimited email or SMS access, and a store that started on Pro may find it can drop to Standard once the SMS volume settles. Count the contacts again too, because Omnisend bills the whole list, and a segment of dead contacts that never opens should be suppressed. The switch saves money once. The habits save it every month after.
Frequently Asked Questions
How long does it take to switch from Klaviyo to Omnisend?
Most small stores finish the switch in one to two weeks. The setup takes an afternoon, the contact import and the flow rebuild take another afternoon, and the two week parallel run catches the problems while Klaviyo is still available. A store with many flows or heavy SMS use should budget three weeks. Do not promise a one day switch, because the manual rebuild and the parallel run are what make the move safe.
Will I lose my contacts when I switch from Klaviyo to Omnisend?
Contacts, lists and the suppression list transfer through CSV export and import, so export each list first and run a pilot import on one list to confirm the mapping. Flows, templates, signup forms and predictive segments do not transfer, so flag them in the audit and rebuild them by hand. Keep Klaviyo running until the Omnisend import is checked, and no contact will be lost.
Is Omnisend really cheaper than Klaviyo?
For email alone, yes, at every list size from 500 to 100,000 contacts. Omnisend Standard costs 16 dollars a month at 500 contacts and 132 dollars at 10,000, against 20 dollars and 150 dollars for Klaviyo Email. At 50,000 contacts the gap is 413 dollars against 720 dollars. The only common case where the saving shrinks is a small store that adds SMS, because Omnisend needs Pro plus a subscription for texting, where Klaviyo adds a 15 dollar plan. Count the SMS volume before deciding.
Does Omnisend have the same flows as Klaviyo?
Omnisend has the same core flows, welcome, abandoned cart, abandoned browse, post-purchase, win-back and birthday, ready in its automation library, but flows do not transfer, so the store rebuilds each one by hand. Klaviyo predictive segments and custom event triggers have no direct match, so those must be replaced with behavior segments. Pick the three flows that earn the most and rebuild those first.
Can I keep my Klaviyo email templates when I switch?
No, templates do not transfer as editable designs. Each template must be rebuilt in the Omnisend editor, copying the copy, the images and the discount codes from Klaviyo. Export the Klaviyo templates as a reference before cancelling, and rebuild the top templates first. A store with a large template library should treat the rebuild as a cleanup and keep only the designs it still sends.
The Call
Switch to Omnisend if the store pays for Klaviyo Email and only uses the core flows, if the list is growing and the bill climbs faster than revenue, or if the store wants email, SMS and web push on one bill with 24/7 support. A store with 5,000 to 50,000 contacts will save hundreds to thousands of dollars a year, get the same welcome, cart and post-purchase flows it already runs, and lose nothing it actually uses, as long as the audit flags the predictive segments and the SMS consent first. For those stores, learning how to switch from Klaviyo to Omnisend is worth an afternoon, and the saving repeats every month.
Stay on Klaviyo if the store lives on predictive analytics and product recommendations, if the segments are built on predicted lifetime value and churn risk, or if the store is mid sale and cannot afford a week of parallel running. A store that earns its edge from deep segmentation will feel Omnisend as a step down, and a store with heavy SMS use at a small list size can find the saving smaller than the headline suggests. Stay also if the contract renewal is close and the team is mid launch. A switch during a launch costs more in chaos than it saves in subscription fees.
The decision rule is simple. Count the contacts, count the SMS volume, list the flows the store actually runs every week, and run the two totals with SMS included. If Omnisend covers the weekly workflow and costs less, switch in a quiet week and follow the seven steps. If Klaviyo covers a weekly workflow that Omnisend cannot match, stay and renegotiate the Klaviyo plan instead. The right tool is the one that matches the work, not the one with the lower headline price.
