Klaviyo Alternatives for Ecommerce Email and SMS

By Rene Siller, Zobi.

Compare Klaviyo alternatives for ecommerce email and SMS. See which workflows, subscriber data, and shopper conversations you need to keep when switching.

## Quick answer

If you’re looking for Klaviyo alternatives because of the bill, ask for quotes based on the same audience and send volume before rebuilding any flows. Omnisend is worth comparing if you want email and SMS together. Look at Attentive or Postscript when SMS is the main reason to change, and Zobi if you need someone to handle replies while your existing email program stays in place.

Keep Klaviyo if your current setup supports the workflows you rely on and a like-for-like quote leaves too little savings to cover the move. Zobi publishes this guide and appears in the shortlist.

## Compare the work that needs to move

Option | Why compare it | Test before moving
Omnisend | Rebuild email and SMS in one ecommerce program. | A conditional flow that reads a store event.
Attentive | Prioritize messaging, subscriber growth or service. | Which email flows and handoffs the proposal covers.
Postscript | Split out Shopify SMS. | Who coordinates the active email and SMS flows.
Zobi | Handle shopping conversations alongside your stack. | What happens to replies and support issues.

## Omnisend for combined email and SMS

Quote Omnisend on your actual contact count and channel mix. Ask the vendor to reproduce a branch using purchase and engagement data.

## Attentive when SMS or service drives the change

Ask Attentive Concierge to show the reply setup if that is part of the case. Check which email automations are included in the same proposal.

## Postscript for a separate SMS program

Use Postscript’s terms to price SMS alongside the email platform you plan to keep. Assign an owner to each trigger and suppression rule.

## Zobi when the missing work is a conversation

Test the shopper question that your existing flow cannot resolve. Keep the work of sending email in the proposal where it belongs. See Zobi for Shopify .

## Before moving working Klaviyo flows

Changing platforms means checking flows, offer timing and suppression again. If the sticking point is what happens when someone answers the cart reminder, start with that reply.

Zobi can use the Shopify cart and conversation to help the shopper continue. Bring a question your current flow sends to your team and compare how each approach would handle it.

## Check that imported orders change the branch without starting a send

Klaviyo’s recovery setup uses a checkout event to start a flow and a separate order check to decide whether messages continue. For a post-purchase migration, ask which event starts the replacement flow and which field it reads to tell first-time and repeat buyers apart. Klaviyo’s flow trigger and filter example

In a test account, use two opted-in profiles. Give one an order dated before the migration. Import that order and look for it on the profile before placing any new orders. It should count toward purchase history without starting a new follow-up.

Place the same kind of new order for both shoppers. The first should enter the first-purchase branch and the second the repeat-purchase branch. If both take the same branch, inspect the imported order and the field the branch reads before rewriting the flow.

## Compare both proposals on the same month

Use your current Klaviyo plan basis as the starting point. Quote active contacts, each channel, and the staff or service needed to recreate and run the flows.

## Compare Klaviyo SMS alternatives if you want to keep email

If email already works in Klaviyo, ask each SMS alternative to run a single Shopify recovery flow alongside it. Let Klaviyo keep email. Give the new platform sole ownership of the SMS step, and agree who will answer a shopper’s reply. That isolates what you need to replace before you move other flows.

Export the phone number, SMS marketing consent and its timestamp. Klaviyo’s export guide lists those fields. In the destination, check one profile that opted out and one that gave email permission only. Neither should enter the SMS recovery queue. Klaviyo’s consent documentation distinguishes SMS marketing permission from transactional permission and email consent.

Then run an eligible abandoned checkout on a test profile. Check that Klaviyo queues only the expected email and the alternative queues the expected text. Place the order before the text is due and check whether the pending message stops. Ask the supplier to show both queues. An import that matches the contact count can still leave the next send in two places.

## Would the cheaper quote cover the same audience?

Start with your latest Klaviyo invoice and the account count it uses. Klaviyo prices email around active email profiles and send volume. Its definition can include someone who supplied an email at checkout without opting in to ongoing marketing. Suppressed profiles stay in the account and are excluded from the email plan count. Klaviyo says they still count toward the total if you use Advanced KDP. Give both vendors the same aggregate account snapshot, then compare what each one counts. Klaviyo’s profile and billing definitions

Have your email owner record how many people your team needs to reach and how many profiles you need to retain for history or suppression. Ask each vendor what it will bill for, including profiles it counts even if you never mail them. Use the same month of email sends and SMS usage on both quotes. If your audience or sends jump around a sale, get the same quote for that month too. Keep your existing consent and suppression rules while comparing prices.

Then ask the person who would move the program for a one-time figure covering rebuild, validation and overlap. If you have to move by a set date, compare total costs through the same end date. If the timing is flexible and monthly savings are steady, dividing the one-time cost by the monthly saving tells you how many months it would take to recover the move. A quote that saves nothing on the same scope has no payback from subscription savings.

If the difference shrinks once both vendors count the same audience, price keeping Klaviyo and changing only the part of the program causing trouble. A full switch makes more sense when the equivalent quote still leaves enough room to cover the work and the new platform can run the flows you actually use.

## Find out what your Klaviyo account is doing for you

Before comparing platforms, pick the Klaviyo segments and flows you would miss if they stopped on Monday. A Shopify store might depend on a first-order welcome, an accessory offer for recent repeat buyers and a replenishment reminder tied to a product. Save the rules and a few example profiles for each. The rules tell a finalist what to reproduce. The profiles show whether the new system actually made the same decisions.

Separate four kinds of information. Contact records identify the shopper. Subscription and suppression states determine which sends they can receive. Events tell you what they did and when. Flow and segment rules turn those events into a decision. A contact export may cover the first two and leave the buying history or the logic behind. In Klaviyo’s Shopify documentation, a placed order and an ordered product are separate events with different properties. Check which event the existing rule uses before asking a new tool to replace it. Klaviyo’s Shopify data reference .

Keep your current setup on the table. If the real problem is a pricey profile tier, pull the last invoice and ask which profiles count. If a single branch is unreliable, ask someone to fix that branch and test it in the existing account. A replacement is easier to justify when a recurring operational problem survives that test or when the new tool can show a material saving after the rebuild. Klaviyo’s plan and active profile terms .

## Check whether the segment still changes after the import

Omnisend describes a Klaviyo importer for contacts and compatible segments. It can map subscription states, and a segment whose filters it cannot reproduce can fail. Its documentation distinguishes rebuilding the conditions from importing the people who matched at export time. A snapshot can be useful for a one-off campaign. A repeat-buyer flow needs the audience to change after the next purchase. Omnisend’s Klaviyo import and segment guide .

Shopify order history has its own route. Omnisend says its Shopify connection starts syncing orders, contacts and products. Your Klaviyo account may also contain events from a separate app or import. For each event you need, ask where it originated, whether the replacement receives it, and which timestamp and identifier survive. Ask the vendor to show the record rather than treating a successful contact count as proof of historical coverage. Omnisend’s Shopify sync reference .

Preserve original event time and the link to the right shopper. Klaviyo’s manual event import documentation illustrates the difference between a timestamp, a customer identifier and a unique event ID. The replacement can use different field names, but it still needs to tell two purchases apart and recognize when a retry refers to the same order. In the test, enter one historical order, resend the same order reference and check whether the count stays at one. A duplicated order can place a first-time buyer in the repeat group. Klaviyo’s event import fields and duplicate handling .

## Will the codes you already sent still work at checkout?

The new welcome email can look right and still break a promise made by the old one. A shopper might open yesterday’s message after you switch providers and try its unique code at checkout. If it fails, the person answering the reply needs to know whether the code expired, was already used or no longer matches the store’s discount rule.

Old and new codes can coexist during a cutover The replacement welcome flow goes live Shopper already has a code Try the original code on an eligible cart. Keep its existing rules. Shopper just signed up Check that the replacement issues a code and that checkout accepts it under its own rules. The new welcome flow is only half the test. Use the two codes at checkout before switching off the old setup.

Klaviyo’s Shopify coupon documentation explains that editing a coupon definition in Klaviyo creates a new Shopify price rule and leaves already sent codes on the prior rules. Editing that existing rule in Shopify can affect codes already sent. Ask the finalist whether moving the welcome requires touching that old rule, and who will own it while issued codes remain usable.

In a test store, generate an unused code from the old welcome and record its expiry and qualifying cart. Recreate the offer in the proposed sender with a separate rule. Test the old code on its original eligible cart, then trigger the new welcome for a second profile and test the code it receives. Try an ineligible cart as a control so you can distinguish a working offer from an overly broad one.

If the finalist can send new codes but cannot explain the old ones, keep the old discount rule in place while you investigate. Include ownership of older offers in the switching work.

## Replay a repeat-buyer segment with three shoppers

Say the store sends an accessory offer to people who placed at least two qualifying orders within the last 60 days. Use three test profiles and check their order count at the point when the new purchase has arrived. Set the rule and the expected branch first. Record the source order reference and original event time for every row.

Before the switch | Test action | Expected result
One order 40 days ago | Import history. Place a new qualifying order today. | No send on import. The new order creates two within 60 days and qualifies the shopper for the repeat-buyer branch.
One order 75 days ago | Import history. Place a new qualifying order today. | The old order stays on the profile, outside the window. One qualifying order. The shopper stays out of the repeat-buyer branch.
No prior order | Place one order and replay the same order reference. | One qualifying order and one intended follow-up. The duplicate does not create a second purchase.

Then add the failure that would matter most in your store. If customers can order as a guest with a different email, test whether the order joins the profile that actually owns consent. If cancelled or refunded orders should lose eligibility, add one of those events and check what the flow reads. Your definition of a qualifying order belongs in the test. A new vendor’s default might differ.

Ask for three records for each shopper. One shows the Shopify order and original time. One shows the matched profile and the segment state before and after the live event. The last shows the action that queued or skipped. If a contact count matches but the second profile joins the repeat group, investigate the date logic. If the first shopper never joins, compare the historical event and identity match. Those two failures need different fixes.

## Choose the smallest move that passes the replay

Omnisend is a candidate for a whole email and SMS move. Use the segment replay above and assign a person to recreate your critical flows. Omnisend’s own workflow guide tells merchants to map triggers, timing and splits when rebuilding. Ask the vendor to show the replacement with a field your existing flow actually needs, such as the product ID or order timestamp. A working template with a simpler rule is a useful demo and leaves the hard migration question open. Omnisend’s workflow migration steps .

Postscript and Attentive give you a narrower route when the main problem is SMS. Ask who will keep Klaviyo email running and which system can stop a text when the shopper has ordered. Postscript publishes separate terms for its marketing plans and managed program. Attentive describes Concierge as a service with AI and live agents. When conversations are the specific gap, Zobi is another narrow option. Price the actual SMS or reply service beside the Klaviyo work that would stay. Postscript pricing and services . Attentive Concierge . Zobi’s shopper conversation service .

For a new combined program, ask for one current-volume quote and one peak-volume quote. Include plan and usage, the number of flows that need rebuilding, any sending-domain or number setup, time spent checking past data, and the cost of running both systems during a handover. Ask the finalist to identify which work is included and which remains with the store. A small reduction in the monthly plan can disappear during an overlap if your team still owns the rebuild.

Agree on a cutoff only after the replay succeeds. Compare suppressed and subscribed test contacts by channel, then check the old and new queues before activating the new route. Keep a rollback owner who can pause the replacement and restore the intended route without reopening both at once. If an essential segment can only move as a static list and your flow needs live membership, keep that flow with Klaviyo while you test a different migration plan.
