TxtCart is the strongest Retainful alternative for stores whose cart recovery lives on SMS, because a shopper who texts back “will this arrive before Friday?” gets an answer in the same thread instead of another scheduled reminder. That is what conversational SMS cart recovery is built for.
TxtCart does not replace Retainful’s email or WhatsApp. It replaces the SMS half and runs alongside whatever keeps carrying the rest.
The harder question is which channels you actually need. Every tool below prices a different unit: contacts, emails sent, recovered revenue, destination country, browser permissions. Match the billing unit to the shopper moment you are trying to rescue and the seven options below sort themselves fast.
The column that decides most of these is not price, it is what drives the bill. Two tools at near-identical monthly rates can invert once a list doubles or a recovery month goes well. The replies column reflects public product positioning, not a hands-on feature audit, and Retainful is the anchor these seven are measured against rather than a ranked pick.
If the real job is texting generally rather than recovery specifically, the wider Shopify SMS app roundup covers campaign and list-growth tools too.

Where Retainful falls short according to users online
Retainful is genuinely good at the thing most cheap tools are bad at: getting email, SMS, and WhatsApp recovery live on a small store’s budget. A 2025 Shopify reviewer credits the free plan and the setup with getting a brand-new store’s recovery running. The notes below come from Retainful’s own site and pricing page, its help center, and its Shopify App Store listing and reviews, accessed 2 August 2026.
- →The free plan is a 500-email monthly allowance: Cart recovery, flows, forms, and segmentation are all included at $0, but the send cap is what a growing store hits first, usually in its first busy month. (sources: Retainful pricing page, Retainful Shopify listing)
- →The $14 tier advertises unlimited contacts and a per-contact charge in the same breath: The listing pairs unlimited contacts and sends of up to 10x list size with $4 per additional 500 contacts. Get in writing which unit your bill actually scales on. (source: Retainful Shopify listing)
- →WhatsApp is free from Retainful and invoiced by Meta: Retainful states it adds no markup and merchants pay Meta directly, so the channel that reads as free on the pricing page arrives as a second bill you have to forecast yourself. (source: Retainful pricing page)
- →Public materials describe sending on three channels, not handling what comes back: Broadcasting across email, SMS, and WhatsApp is a different job from staffing a reply on any one of them. (source: retainful.com)
- →Platform support is Shopify and WooCommerce: A store on BigCommerce, Wix, or a custom stack is outside the supported set. (source: Retainful help center)
- →The review base is 27: 4.4/5 from 27 Shopify reviews, with counts that differ across cached and localized versions of the listing, so read them in full rather than trusting the average. (source: Retainful Shopify reviews)

02. Omnisend
The balanced suite when recovery is one flow among eight, from $16 a month.
Consolidation is the argument. Welcome, browse, winback, and cart flows sit in one place instead of three apps with three logins and three attribution windows.
Free covers 250 contacts, 500 emails, and 500 web push sends a month (Omnisend pricing). 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 between $10 and $49.99 of volume, stepping down to $0.007 at $10,000 and above. The app is rated 4.8 across 2,942 Shopify reviews (Shopify listing).
Best fit: stores whose recovery problem is really a lifecycle problem. The Omnisend alternatives comparison covers the SMS-first side of that tradeoff.
Shopify rating ★ 4.8
Key features
- Consolidation is the argument: welcome, browse, winback, and cart flows sit in one place instead of three apps with three logins and three attribution windows
- Free tier: 250 contacts, 500 emails, and 500 web push sends a 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 between $10 and $49.99 of volume, stepping down to $0.007 at $10,000 and above
- 4.8/5 across 2,942 Shopify reviews: one of the two deepest review bases on this list
Omnisend’s Pricing
- Free – $0/mo, 250 contacts, 500 emails, and 500 web push sends a 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 between $10 and $49.99 of volume, stepping down to $0.007 at $10,000 and above
- Bill basis – contacts set the tier and SMS is billed by spend band, where email volume sets the tier on Retainful (free, then $14/mo)
Heads up
Based on user reviews
- SMS sits behind the $59 plan: a store that wants texts alone pays for an email suite to reach them.
- Contact ceilings arrive early: 500 contacts on Standard is a starter allowance, and the bill steps up as the list grows.

03. Klaviyo
Segmentation depth for stores past their first cart flow, from $20 a month.
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 email contacts, with SMS priced apart from $15/mo for up to 1,250 SMS or MMS credits, and the app is rated 4.7 across 2,933 Shopify reviews (Shopify listing).
Best fit: stores with someone to own the data model, not just the send button. 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 reason to be here: 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 email contacts
- SMS priced apart: from $15/mo for up to 1,250 SMS or MMS credits
- 4.7/5 across 2,933 Shopify reviews: a deep base to read before committing
Klaviyo’s Pricing
- Free – $0/mo, 250 profiles, 500 emails a month, and $5 of mobile messages
- Email – $20/mo, 251 to 500 email contacts
- SMS – from $15/mo, up to 1,250 SMS or MMS credits, priced apart from email
- Bill basis – active profiles set the tier, where contacts and sends set the tier on Retainful (free, then $14/mo)
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.

04. Recapture
Recovery priced against the revenue it brings back, from $39 a month.
The bill moves with results: 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 (Recapture pricing). SMS is a $20 step up from 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 and no card required (Shopify listing).
Best fit: stores that want recovery as a line item defensible against exactly what it 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 is a $20 step up from the email plan: not a separate metered contract
- 5.0/5 from 34 Shopify reviews: with a 15-day full-featured trial and no 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 card required
- Bill basis – recovered revenue sets the tier, where list size sets the tier on Retainful (free, then $14/mo)
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 tracks the win.
- The published example and the plan table start at different numbers: the pricing FAQ illustrates a $29 base tier while the plan display starts at $39, so get your starting tier confirmed in writing.

05. PushOwl
Free browser reminders for abandoners who never left a number, from $19 a month.
Push needs no phone number and no email address, just a browser permission, which makes it the only recovery channel that reaches a shopper you cannot otherwise identify.
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). PushOwl also sits on TxtCart’s partner directory, so the two are built to 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 a shopper you cannot otherwise identify
- 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 are built to run together
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 – the push send allowance sets the tier, where email volume sets the tier on Retainful (free, then $14/mo)
Heads up
Based on user reviews
- Push notifications cannot be replied to: the channel is one-directional by design, so a shopper’s question has nowhere to land.
- Unlimited subscribers is not unlimited sends: subscribers keep collecting after the send allowance runs out, and limits reset monthly.
- The Shopify listing now reads Brevo PushOwl: the product sits inside Brevo’s suite, which matters when you map out logins and billing.

06. CartBoss
No monthly fee, with each text priced by destination country.
Reminders run preconfigured in the background and an invoice only exists when a message goes out.
Rates are published in euros by destination: €0.025 to a US number, €0.0278 to Canada, €0.0557 to the UK, €0.0788 to Australia (CartBoss pricing). DND and silent hours ship with the app, so late-night sends do not happen by accident (CartBoss Shopify listing). It carries 3.9/5 from five Shopify reviews, four of them from stores in one country, and a base that small proves a pattern in neither direction.
Best fit: a store shipping mostly to one country that wants a reminder running unattended. Anything that depends on the shopper answering belongs on a platform built for two-way SMS marketing.
Shopify rating ★ 3.9
Key features
- No monthly fee: an invoice only exists when a message goes out
- Rates published in euros by destination: €0.025 to a US number, €0.0278 to Canada, €0.0557 to the UK, €0.0788 to Australia
- DND and silent hours ship with the app: so late-night sends do not happen by accident
- 3.9/5 from five Shopify reviews: four of them from stores in one country, a base too small to prove a pattern in either direction
CartBoss’ Pricing
- Monthly fee – $0/mo, pay per text
- Per text – €0.025 to a US number, €0.0278 to Canada, €0.0557 to the UK, €0.0788 to Australia
- Bill basis – destination country sets the rate, where email volume sets the tier on Retainful (free, then $14/mo)
Heads up
Based on user reviews
- The per-text rate is nowhere near the install button: the listing advertises $0 monthly fees and pay per text, then sends you elsewhere for the actual numbers.
- 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.

07. Privy
Onsite capture first, email and SMS second, from $24 a month.
The strength here sits upstream of recovery. Popups and displays collect the address or number every other tool here needs before it can send anything.
Three products, three prices: Pop Ups and Displays from $24/mo, Email from $30/mo for up to 1,500 contacts, Email + SMS from $45/mo for 1,500 email contacts and 1,250 SMS credits (Shopify listing). It carries 4.5/5 from 3,983 Shopify reviews, the largest review base among the seven, and support shows up as a strength, with multiple March 2026 reviews singling out fast human help.
Best fit: stores where the recovery list is too small to matter yet and capture is the actual bottleneck.
Shopify rating ★ 4.5
Key features
- Capture sits upstream of recovery: popups and displays collect the address or number every other tool here needs before it can send anything
- Three products, three prices: Pop Ups and Displays from $24/mo, Email from $30/mo for up to 1,500 contacts, Email + SMS from $45/mo for 1,500 email contacts and 1,250 SMS credits
- 4.5/5 from 3,983 Shopify reviews: the largest review base among the seven
- Support shows up as a strength: multiple March 2026 reviews single out fast human help
Privy’s Pricing
- Pop Ups and Displays – from $24/mo
- Email – from $30/mo, up to 1,500 contacts
- Email + SMS – from $45/mo, 1,500 email contacts and 1,250 SMS credits
- Bill basis – page views, email contacts, and SMS credits move apart, where email volume sets the tier on Retainful (free, then $14/mo)
Heads up
Based on user reviews
- Three plans scale on three different units: and localized listings show different caps, so confirm the ones attached to your account.
- One July 2026 reviewer reported an unexpected step from $15 to $45: a single report is not a billing pattern, but it is worth knowing which unit trips your next tier.

The Verdict
TxtCart wins for the store losing checkouts to unanswered questions, because the reply is the recovery mechanism rather than a support ticket that arrives two days after the cart went cold.
Omnisend is the better call when recovery is one flow inside a full lifecycle program. Recapture is the cleanest fit when recovery is the whole budget and you want the bill tied to what came back.
Staying on Retainful is a legitimate outcome. If email, SMS, and WhatsApp all need to be live and the entry price matters more than depth on any one of them, nothing on this list does that job for less.
