TxtCart is the strongest CartBoss alternative for most Shopify stores, because a shopper who texts back “does this ship to Canada?” gets an answer instead of another reminder. That is the real fork here, and it is what conversational SMS cart recovery is built for.
CartBoss charges €0.025 per text to a US number with no monthly fee. Usage-based Shopify platforms meter US texts at $0.007 to $0.009 and charge a plan fee instead. Which model wins depends on volume, channel mix, and whether anyone needs to handle replies. Those three questions separate the seven alternatives below.
Pricing is the lowest public entry point at each vendor’s own source, and the replies column reflects public product positioning rather than a feature audit. CartBoss is the anchor these seven are measured against rather than a ranked pick.
TL;DR – At a glance
| # | App | Recovery channels | Built for replies | Pricing basis | Review signal | Best fit |
|---|---|---|---|---|---|---|
| 01 | TxtCartRecommended | SMS | Core: AI plus live agents | From $29/mo + metered SMS | 4.9/5 (443) | Checkouts lost to unanswered questions |
| 02 | Recart | SMS | Partial: managed by a strategist | From $299/mo on a commitment | 4.7/5 (447) | Stores with nobody to own SMS |
| 03 | Retainful | Email, SMS, WhatsApp | Not the focus | Free, then $14/mo | 4.4/5 (27) | Cheapest multi-channel entry |
| 04 | Recapture | Email, SMS | Not the focus | From $39/mo, scales on recovered revenue | 5.0/5 (34) | Recovery-only budgets |
| 05 | Omnisend | Email, SMS, push | Not the focus | Free, $16, or $59/mo | 4.8/5 (2,942) | All lifecycle email on one small bill |
| 06 | Klaviyo | Email, SMS, WhatsApp | Partial | Free, email $20/mo, SMS $15/mo | 4.7/5 (2,933) | Segmentation-heavy programs |
| 07 | PushOwl | Push, email, SMS | No reply path on push | Free, $19, or $79/mo | 4.8/5 (2,012) | Shoppers who never gave you a number |
Where CartBoss falls short according to users online
CartBoss is genuinely good at one thing: preconfigured reminders that run without anyone touching them. A Slovenian merchant of two-plus years calls it “one of the few apps that pays for itself,” and the app ships with DND and silent hours so late-night sends do not happen by accident. The evidence below comes from CartBoss’s own site and pricing page plus every review currently on its Shopify App Store listing, accessed 2 August 2026.
- The per-text rate is nowhere near the install button: The Shopify listing advertises “$0 monthly fees” and “pay per text message,” then sends you elsewhere for rates. (sources: CartBoss Shopify listing, CartBoss pricing page)
- Sending is priced in euros, by destination country: €0.025 to a US number, €0.0278 to Canada, €0.0557 to the UK, €0.0788 to Australia. A store shipping worldwide quotes itself a different price per market with every send. (source: CartBoss pricing page)
- Nothing in the public feature list covers a reply: The listed capabilities stop at the delivery side: scheduling, custom delays, language detection, sender ID, opt-in management. A shopper who answers the text is answering into a channel the product does not describe handling. (sources: cartboss.io, CartBoss Shopify listing)
- The review base is five reviews, and four are from one country: 3.9/5 from five: four five-star, one one-star, with four posted by Slovenia-based stores. Too small a sample to prove a pattern in either direction. (source: CartBoss Shopify reviews)
- The single negative review is a support complaint the vendor disputes: A Netherlands merchant reported invoices arriving while emails went unanswered on 31 July 2025; CartBoss replied that it answered all three messages within 24 hours. (source: CartBoss Shopify reviews)
- The headline performance numbers are vendor claims with no published method: “99% Open Rate” and “50%+ Click Rate” appear on the homepage without sample size, date range, or definition. (source: cartboss.io)

02. Recart
Managed SMS with a strategist attached, from $299 a month.
Recart sells the operator as much as the software: a customer success manager runs the popups and campaigns, which is a different purchase from a self-serve app.
Pricing is commitment-based, not month-to-month. Starter is $299/mo on a 12-month term, $319 on six months, $345 on three (Recart pricing). List growth is bundled in, with OneClick Opt-in popups and unlimited subscribers on every tier. The app is rated 4.7 across 447 Shopify reviews, with a free migration plan and a 7-day trial on Starter (Shopify listing).
Best fit: stores doing real SMS volume with nobody in-house to own the calendar. The Recart alternatives breakdown goes deeper on managed versus self-serve.
Shopify rating ★ 4.7
Key features
- A strategist, not just software: a customer success manager runs the popups and campaigns on your behalf
- Commitment-based pricing: Starter is $299/mo on a 12-month term, $319 on six months, $345 on three
- List growth bundled in: OneClick Opt-in popups and unlimited subscribers on every tier
- 4.7/5 across 447 Shopify reviews: with a free migration plan and a 7-day trial on Starter
Recart’s Pricing
- Starter – $299/mo on a 12-month term, $319 on six months, $345 on three
- Per message – $0.0100 to $0.0045 per SMS
- Trial – 7 days on Starter, plus a free migration plan
- Bill basis – a fixed platform fee on a term commitment, where CartBoss bills per text with no monthly fee
Heads up
Based on user reviews
- The floor is high for a recovery-only job: $299 a month before a single text is sent is a large fixed cost if abandoned checkouts are the only flow you need.
- The term commitment is the tradeoff for the strategist: quarterly is the shortest option, so testing costs a quarter, not a month.

03. Retainful
The cheapest way to put email, SMS, and WhatsApp behind one cart, from $14 a month.
For a store whose abandoners never opted into SMS, email is still the only door, and Retainful is the cheapest way to open three of them at once.
The free plan is usable, not a demo: 500 emails a month with abandoned cart recovery, flows, signup forms, and segmentation included. Pro is $14/mo with unlimited contacts, sending up to 10x your list size, plus $4 per additional 500 contacts. The app is rated 4.4 from 27 reviews, a modest base worth reading in full before committing (Shopify listing).
Best fit: small stores that want email recovery working this week and SMS as a secondary nudge, on the smallest possible bill.
Shopify rating ★ 4.4
Key features
- Three channels behind one cart: email, SMS, and WhatsApp recovery from a single app
- A free plan that is usable, not a demo: 500 emails a month with abandoned cart recovery, flows, signup forms, and segmentation included
- Pro at $14/mo with unlimited contacts: sending up to 10x your list size, plus $4 per additional 500 contacts
- 4.4/5 from 27 Shopify reviews: a modest base worth reading in full before committing
Retainful’s Pricing
- Free – $0/mo, 500 emails a month with cart recovery, flows, forms, and segmentation
- Pro – $14/mo, unlimited contacts, sending up to 10x your list size
- Add-on – $4 per additional 500 contacts
- Bill basis – email volume drives the bill, where destination country drives it on CartBoss
Heads up
Based on user reviews
- Channel breadth is not channel depth: three channels at $14 buys coverage; it does not buy conversation handling on any of them.
- The review base is 27: compared with the thousands behind Omnisend or Klaviyo, sentiment here moves on a handful of opinions.

04. Recapture
Recovery priced against the revenue it recovers, from $39 a month.
Recapture bills on outcomes rather than list size, setting your tier from the revenue it helped recover over the previous 30 days.
Three clean plan paths: Cart Recovery at $39/mo, Cart Recovery + Email at $58/mo, and Cart Recovery + SMS at $59/mo (Recapture pricing). SMS is $20 more than the email plan, not a separate metered contract. The app is rated 5.0 from 34 Shopify reviews with a 15-day full-featured trial, no credit card required (Shopify listing).
Best fit: stores that want abandoned-cart recovery as a line item they can defend, priced against what it actually brought back.
Shopify rating ★ 5.0
Key features
- Outcome-based tiers: your tier is set by the revenue Recapture helped recover over the previous 30 days
- Three clean plan paths: Cart Recovery at $39/mo, Cart Recovery + Email at $58/mo, Cart Recovery + SMS at $59/mo
- SMS costs $20 more than the email plan: not a separate metered contract
- 5.0/5 from 34 Shopify reviews: with a 15-day full-featured trial, no credit card required
Recapture’s Pricing
- Cart Recovery – $39/mo
- Cart Recovery + Email – $58/mo
- Cart Recovery + SMS – $59/mo
- Trial – 15 days, full-featured, no credit card required
- Bill basis – scales with recovered revenue, where CartBoss scales with texts sent
Heads up
Based on user reviews
- Success-linked pricing cuts both ways: a strong recovery month raises next month’s tier, so the cost curve moves with the win.
- The published example and the plan table use different base numbers: the pricing FAQ illustrates a $29 base tier while the plan display starts at $39, so confirm your starting tier in writing.

05. Omnisend
Email, SMS, and push on one small bill, from $16 a month.
The value here is consolidation: welcome, browse, winback, and cart flows in one place instead of three apps with three logins.
Free covers 250 contacts, 500 emails, and 500 web push sends per month. Standard is $16/mo for 500 contacts and 6,000 emails; Pro is $59/mo for 2,500 contacts and unlimited emails. SMS is a Pro-tier add-on billed by spend band, $0.009 per message at $10 to $49.99 of volume, stepping down to $0.007 at $10,000 and above (Omnisend pricing).
Best fit: stores whose recovery problem is really a lifecycle problem, where cart emails are one flow among eight. The Omnisend alternatives comparison covers the SMS-first side of that tradeoff.
Shopify rating ★ 4.8
Key features
- Consolidation is the point: welcome, browse, winback, and cart flows in one place instead of three apps with three logins
- Free tier: 250 contacts, 500 emails, and 500 web push sends per month
- Standard and Pro: $16/mo for 500 contacts and 6,000 emails, or $59/mo for 2,500 contacts and unlimited emails
- SMS billed by spend band: $0.009 per message at $10 to $49.99 of volume, stepping down to $0.007 at $10,000 and above
Omnisend’s Pricing
- Free – $0/mo, 250 contacts, 500 emails, and 500 web push sends per month
- Standard – $16/mo, 500 contacts and 6,000 emails
- Pro – $59/mo, 2,500 contacts and unlimited emails
- SMS – a Pro-tier add-on billed by spend band, $0.009 per message at $10 to $49.99 of volume, stepping down to $0.007 at $10,000 and above
Heads up
Based on user reviews
- SMS sits behind the $59 plan: a store wanting texts alone pays for an email suite to reach them.
- Contact ceilings arrive quickly: 500 contacts on Standard is a starter allowance, and the bill steps up as the list grows.

06. Klaviyo
The segmentation engine, once the data is worth the setup.
Klaviyo earns its place when the question stops being whether the reminder went out and becomes which segment abandoned, holding what, at what lifetime value.
Free is real but tight: 250 profiles, 500 emails a month, and $5 of mobile messages (Klaviyo pricing). Paid entry is $20/mo for 251 to 500 contacts on email, and $15/mo for up to 1,250 SMS or MMS credits. The app is rated 4.7 across 2,933 Shopify reviews, the deepest review base in this list alongside Omnisend (Shopify listing).
Best fit: stores past the point where one cart flow is enough, with someone to own the data model. The Klaviyo alternatives roundup is the better next read if the price ladder is the sticking point.
Shopify rating ★ 4.7
Key features
- Segmentation is the product: which segment abandoned, holding what, at what lifetime value
- Free is real but tight: 250 profiles, 500 emails a month, and $5 of mobile messages
- Paid entry: $20/mo for 251 to 500 contacts on email, and $15/mo for up to 1,250 SMS or MMS credits
- 4.7/5 across 2,933 Shopify reviews: the deepest review base in this list alongside Omnisend
Klaviyo’s Pricing
- Free – $0/mo, 250 profiles, 500 emails a month, and $5 of mobile messages
- Email – $20/mo, 251 to 500 contacts
- SMS – $15/mo, up to 1,250 SMS or MMS credits
- Bill basis – scales with active profiles, where CartBoss scales with texts sent
Heads up
Based on user reviews
- Profile-based billing rewards list hygiene: inactive profiles you never message still count toward the tier.
- The setup curve is the real cost: segments, flows, and attribution take configuration time before the sophistication pays for itself.

07. PushOwl
Free browser reminders for the shoppers who never gave you a number.
Push is the only recovery channel that needs no phone number and no email address, just a browser permission, which makes it the cheapest way to reach an anonymous abandoner.
The free bundle covers 500 web push sends and 500 emails a month with unlimited subscribers. Plus is $19/mo for 10k to 30k push sends; Power is $79/mo for unlimited push, adding browse abandonment and segmentation. The app is rated 4.8 across 2,012 Shopify reviews (Shopify listing), and PushOwl is listed on TxtCart’s own partner directory, so the two run together rather than against each other.
Best fit: stores with heavy anonymous traffic that want a recovery touch before an opt-in exists.
Shopify rating ★ 4.8
Key features
- No contact details required: push needs only a browser permission, so it reaches abandoners who never gave you a number or an email
- Free bundle: 500 web push sends and 500 emails a month with unlimited subscribers
- Plus and Power: $19/mo for 10k to 30k push sends, or $79/mo for unlimited push with browse abandonment and segmentation
- 4.8/5 across 2,012 Shopify reviews: and a listed TxtCart partner, so the two run together rather than against each other
PushOwl’s Pricing
- Free – $0/mo, 500 web push sends and 500 emails a month with unlimited subscribers
- Plus – $19/mo, 10k to 30k push sends
- Power – $79/mo, unlimited push, adding browse abandonment and segmentation
- Bill basis – send caps drive the tier, where destination country drives it on CartBoss
Heads up
Based on user reviews
- Push notifications cannot be replied to: the channel is one-directional by design, so questions have nowhere to land.
- Unlimited subscribers is not unlimited sends: subscribers keep collecting after the impression allowance runs out, and limits reset monthly.
- The Shopify listing is now branded Brevo PushOwl: the product sits inside Brevo’s suite, which is worth knowing before you map out logins and billing.

The Verdict
TxtCart wins for the store losing checkouts to questions, because the answer lands in the same thread that recovered the cart and the per-message rate is public before anyone talks to sales.
Retainful is the better call on a genuinely small budget that needs email, SMS, and WhatsApp coverage for $14 a month. Omnisend is right when cart recovery is one flow inside a full lifecycle program rather than the whole job.
CartBoss still makes sense for a store that wants a preconfigured reminder running in the background with no monthly commitment and no interest in a conversation. That is the use case it was built for.
Before you switch: five things to do in week one
Migrating recovery messaging is where stores accidentally double-text their customers.
- Export only what the original opt-in language lets you export. Subscriber lists and consent records do not automatically travel.
- Log each consent source and date, whether it came from the checkout box, a popup, or a keyword. The SMS marketing compliance guide covers what to keep on file.
- Turn the old flow off before the new one goes live. Two active cart reminders means two texts about the same cart, and one unsubscribe.
- Rebuild timing and discount logic deliberately. Match delays and offer values to what was working, then change one variable at a time.
- Confirm sending eligibility per country and quiet hours before the first campaign, not after the first complaint.
