TxtCart is the pick when SMS is the half that stopped paying, because it answers replies instead of firing one more one-way reminder, and it leaves your native email alone. When email is what outgrew the app, Klaviyo replaces more of it in a single move.
Shopify Messaging is the marketing app for email, SMS, and WhatsApp campaigns. Shopify Inbox is storefront chat. Different products, different decision.
Eight alternatives below, with pricing and review counts pulled 2 August 2026. If texts are the leak, start with what Shopify SMS marketing software actually covers.
Nobody replaces all three native channels at once, and most stores should not try. Shortlisting the whole category instead of one lane? The roundup of the best SMS apps for Shopify goes wider than these eight.
TL;DR – At a glance
| # | App | Takes over | Move when | Trial or free entry |
|---|---|---|---|---|
| 01 | TxtCartRecommended | SMS, cart recovery, popups. Email stays native | Shoppers reply and nobody is answering | 14-day trial |
| 02 | Klaviyo | Email, SMS, customer data | You cannot say which segment drove revenue | Free plan, no time limit |
| 03 | Omnisend | Email, SMS, web push | You want two channels on one small bill | Free plan, 250 contacts |
| 04 | Privy | Popups, email, SMS | Capture is the leak, not sending | Paid plans only |
| 05 | Postscript | SMS only | SMS has a full-time owner and a send calendar | $100 credit, first 30 days |
| 06 | Attentive | SMS, email, RCS, push | You want an account team, not an app | Demo or trial on request |
| 07 | Seguno | Email only | Email needs depth but must stay in the admin | Free to 250 subscribers |
| 08 | Recart | SMS plus the person who runs it | Nobody in-house owns the channel | 7-day trial on Starter |
Where Shopify Messaging falls short according to users online
Shopify Messaging holds 4.7 out of 5 across 4,070 Shopify App Store reviews, and the praise is specific: it is already installed, it charges no plan fee, and it segments on the order data your store already writes.If your program is one list, a few sends a month, and a welcome plus abandoned-checkout automation that both run, stay put. A specialist adds a migration and a second bill and very little else.The limits show up after that. The same five surface across App Store reviews from July 2026, Shopify’s own SMS pricing and Shopify Email cost documentation, and merchant threads on r/shopify, r/AutomateShopify, and r/ShopifyeCommerce.
- →Templates draw the most requests: July 2026 reviewers praise how fast a campaign ships, then ask for more professional designs; one UK retailer called the current set amateurish. (source: Shopify Messaging App Store reviews, July 2026)
- →Reports say what sent, not which segment answered: A July 2026 reviewer asked for segment data inside campaign reports instead of clicking between pages to match a metric to an audience. (source: Shopify Messaging App Store reviews, July 2026)
- →SMS is built to send, not to answer: The documentation covers campaigns, automations, and per-message billing. A shopper who texts back a question is not a workflow the app is built around. (source: Shopify Messaging SMS help docs)
- →Per-message pricing swings by country and message length: US messages ran $0.012 and Canada $0.025 in the reviewed table, and a text long enough to split into segments bills as more than one message. (source: Shopify SMS pricing help, accessed 2 August 2026)
- →The free email allowance goes fast at list scale: The first 10,000 emails each month are free, then $1 per 1,000 after that. A 12,000-contact list sending weekly clears the allowance in week one. (source: Shopify Email cost help docs)
What the SMS lane actually covers, and what stays native
The number-one pick replaces one third of the native app, so it is worth being precise about which third before the list starts.
- Recovery runs as a conversation, not a nudge. TxtCart reports recovering over 33% of abandoned carts through two-way SMS cart recovery at 98% open rates, with AI and live agents handling replies and recovered-order reporting broken out by flow. (source: TxtCart cart recovery page)
- Onsite capture is bundled in. The SMS popup builder reports 10-15% opt-in rates against a 3% industry benchmark, so list growth does not need a separate app. (source: TxtCart popups page)
- The rate card is public before you talk to anyone. Starter $29/mo at $0.009 per SMS, Growth $79 at $0.008, Pro $399 at $0.007, Managed $999 at $0.006, with carrier fees passed through at $0.0029 per SMS. (source: TxtCart pricing)
- Setup is measured in minutes, with 20 template flows to start from instead of an empty automation canvas. (source: TxtCart product pages)
What to weigh: this covers the SMS third of the native app, not all of it. Template quality and segment reporting are email problems, and they stay unsolved until the email side moves too.

02. Klaviyo
Deepest segmentation, and the fix when email is what outgrew native.
Klaviyo is the answer when email is the half that stopped working. Segmentation depth is the reason to move: product, order, and browsing data feed both segments and flows, which is the gap reviewers name in native reporting. SMS can be bought on its own, priced apart from the email plan, which matters when only one channel is being replaced. It is rated 4.7 out of 5 across 2,933 Shopify reviews (Klaviyo Shopify listing).
On cost, entry is a free plan, then $20/mo for email at 251-500 contacts, with SMS from $15/mo for 1,250 credits. Shopify Messaging is $0 to install, and its free email allowance covers a small list before any spend, while TxtCart has no profile meter: above the plan fee, the per-message rate is the whole bill. (Sources: Klaviyo Shopify App Store listing and Shopify Messaging listing, 2 August 2026.)
What to weigh: once segments and flows live here, pulling a single channel back out is a project rather than a toggle.

- Shopify App Store rating: 4.7 out of 5 across 2,933 reviews
Klaviyo’s Pricing
- Free plan – $0/mo for 250 profiles, 500 emails, and $5 of mobile messages a month
- Email – $20/mo at 251-500 contacts
- SMS – from $15/mo for 1,250 credits, priced apart from the email plan
- Pricing from the Klaviyo Shopify App Store listing and Klaviyo pricing page, 2 August 2026
Heads up
Based on user reviews
- The free plan is trial-sized: 250 profiles, 500 emails, and $5 of mobile messages a month (source: Klaviyo pricing page).
- Cost tracks stored profiles, not sends: list growth raises the bill in a month you barely email (source: Klaviyo pricing page).
- 7% of reviews are one-star: against 88% five-star, so the experience is more polarized than a 4.7 average suggests (source: Klaviyo Shopify App Store listing).

03. Omnisend
The cheapest way to run email and SMS side by side.
Omnisend puts both channels on one small bill. Email and SMS share one automation canvas, so a recovery sequence can change channel without a second tool, and SMS is sold at $0.007 per message on Pro, which is competitive per text once the plan fee is already paid. It is rated 4.8 out of 5 across 2,942 Shopify reviews, with 90% of them five-star (Omnisend Shopify listing).
The meter is contacts stored: $16/mo Standard for 500 contacts and 6,000 emails, and $59/mo Pro for 2,500 contacts and unlimited email. Shopify Messaging meters volume sent, so a large dormant list costs nothing to hold, and TxtCart runs one channel metered on messages sent rather than contacts stored. (Sources: Omnisend pricing page and Shopify App Store listing, 2 August 2026.)
What to weigh: the cheap per-message rate only unlocks on the $59 tier, so the true SMS cost includes a plan fee the native app never charges.
Shopify rating ★ 4.8
Key features
- Email and SMS share one automation canvas: a recovery sequence can change channel without a second tool (source: Omnisend features page)
- Shopify App Store rating: 4.8 out of 5 across 2,942 reviews, with 90% of them five-star
- SMS is sold at $0.007 per message on Pro: competitive per text once the plan fee is already paid (source: Omnisend pricing page)
Omnisend’s Pricing
- Standard – $16/mo for 500 contacts and 6,000 emails
- Pro – $59/mo for 2,500 contacts and unlimited email
- SMS – $0.007 per message on Pro
- Pricing from the Omnisend pricing page and Shopify App Store listing, 2 August 2026
Heads up
Based on user reviews
- Contact caps arrive quickly: Standard tops out at 500 contacts, so a mid-size list lands on Pro almost immediately (based on published pricing).
- SMS is an add-on to an email suite: sold as credits alongside campaigns rather than built around reply handling.

04. Privy
Onsite capture first, for stores losing the subscriber before the send.
Privy is the pick when capture is the leak rather than sending. Capture is the product: popups and onsite displays are what merchants buy Privy for, not the sending engine. It sells three lanes at three prices, $24/mo for popups to 10,000 monthly pageviews, $30/mo for email to 1,500 contacts, and $45/mo for email plus 1,250 SMS credits (Privy Shopify listing). It is rated 4.5 out of 5 across 3,969 Shopify reviews, with reviewers naming responsive human support as the reason they stay.
That means three meters: pageviews for popups, stored contacts for email, credits for SMS, plus $150/mo for a dedicated strategist. Shopify Messaging has no popup builder at all, so capture happens at checkout or not at all, while the TxtCart popup builder ships inside the SMS plan with no pageview meter. (Source: Privy Shopify App Store listing, 2 August 2026.)
What to weigh: capture and sending are billed on different meters here, so a store growing fast pays twice for the same good month.
Shopify rating ★ 4.5
Key features
- Capture is the product: popups and onsite displays are what merchants buy Privy for, not the sending engine (source: Privy Shopify product page)
- Three lanes, three prices: $24/mo for popups to 10,000 monthly pageviews, $30/mo for email to 1,500 contacts, $45/mo for email plus 1,250 SMS credits
- Shopify App Store rating: 4.5 out of 5 across 3,969 reviews, with reviewers naming responsive human support as the reason they stay
Privy’s Pricing
- Popups – $24/mo to 10,000 monthly pageviews
- Email – $30/mo to 1,500 contacts
- Email plus SMS – $45/mo for email and 1,250 SMS credits
- Dedicated strategist – $150/mo on top
- Pricing from the Privy Shopify App Store listing, 2 August 2026
Heads up
Based on user reviews
- The SMS bundle is small: 1,250 credits is a campaign or two for a store with real traffic, and that is the entire allowance on the tier (based on published pricing).
- A traffic spike costs money: pageview metering raises the popup bill in a viral week whether or not it converts.

05. Postscript
The Shopify SMS incumbent, with a $49 floor you pay either way.
Postscript is built for a team with a send calendar rather than a store leaning on automations, and campaign tooling is the strength. New accounts get credit toward the first month, enough to read real performance before the minimum bites. It is rated 4.7 out of 5 across 1,141 Shopify reviews, though 2026 reviews raise glitches, unexpected fees on the free plan, and support delays (Postscript Shopify listing).
The monthly floor is the number to model: $0/mo Starter with a $49 minimum spend, $100/mo Growth at $0.008 per SMS, and average US carrier fees of $0.00418 on top. A month without sends bills nothing on Shopify Messaging, and TxtCart has no floor to clear before the published rate applies. (Sources: Postscript pricing page and Shopify App Store listing, 2 August 2026.)
What to weigh: Postscript prices like a channel with a full-time owner. Stores where SMS is one person’s third priority pay the floor without filling the calendar that justifies it.

- Starter – $0/mo with a $49 minimum spend
- Growth – $100/mo at $0.008 per SMS
- Carrier fees – average US fees of $0.00418 per SMS on top
- Pricing from the Postscript pricing page and Shopify App Store listing, 2 August 2026
Heads up
Based on user reviews
- The minimum applies whether you send it or not: a fixed cost the native app does not charge.
- The cheaper per-message rate sits behind the bigger platform fee: a modest sender pays more up front to unlock a fraction of a cent.

06. Attentive
An account team attached to the software, priced by quote.
Attentive sells a relationship as much as a product. Pricing is quoted, not published: Attentive prices on message volume, subscriber list size, channel count, and which AI products you take (Attentive pricing page). Channels are modular as well, with SMS/MMS, email, RCS, and push bought as packages rather than as one bundled plan, which is why the number varies so widely.
How you get a number: usage-based, billed on what you actually send, with no credit system. Shopify Messaging is published and self-serve with no sales call, and TxtCart publishes every rate, including the managed tier. (Source: Attentive pricing page, 2 August 2026.)
What to weigh: the account team is the thing being bought. A lean store that only needs replies answered is paying for a relationship it will not use.
Joyride left Attentive and drove $1,841,617 with TxtCart
Key features
- Pricing is quoted, not published: Attentive prices on message volume, subscriber list size, channel count, and which AI products you take (source: Attentive pricing page)
- Channels are modular: SMS/MMS, email, RCS, and push are bought as packages rather than as one bundled plan, which is why the number varies so widely
- Usage-based billing: billed on what you actually send, with no credit system
Attentive’s Pricing
- Custom quote – usage-based, priced on message volume, subscriber list size, channel count, and the AI products selected
- AI products – priced on top of the channels, some as flat monthly fees and one on a pay-per-click model
- Pricing from the Attentive pricing page, 2 August 2026
Heads up
Based on user reviews
- Cost discovery takes a sales cycle: time spent before you learn whether the number works (based on published pricing).
- AI products are priced on top of the channels: some as flat monthly fees and one on a pay-per-click model.

07. Seguno
More email depth without leaving the Shopify admin, no SMS lane.
Seguno is the straight email upgrade for a store that liked the native workflow and only wanted the email side to get better. It stays inside the admin, which keeps the workflow advantage that made the native app attractive in the first place, and it runs $35/mo to 2,500 subscribers and $215/mo to 25,000, billed through Shopify with no contracts. (Sources: Seguno Shopify Email alternative page and Seguno pricing page.)
The price tracks active subscribers, so the bill rises with the list rather than with sends. Shopify Messaging bundles email with SMS and WhatsApp in one app with no separate email bill, and TxtCart covers SMS only, so native email keeps the other half. (Sources: Seguno pricing page and Shopify Messaging listing, 2 August 2026.)
What to weigh: this is a straight email upgrade. It answers the template and design complaints and none of the SMS ones.
Key features
- It stays inside the admin: which keeps the workflow advantage that made the native app attractive in the first place (source: Seguno Shopify Email alternative page)
- Billed through Shopify with no contracts: $35/mo to 2,500 subscribers and $215/mo to 25,000 (source: Seguno pricing page)
- The price tracks active subscribers: the bill rises with the list rather than with sends
Seguno’s Pricing
- 2,500 subscribers – $35/mo
- 25,000 subscribers – $215/mo
- Billing – through Shopify, no contracts, with the same 10-day trial on every tier
- Pricing from the Seguno pricing page, 2 August 2026
Heads up
Based on user reviews
- A large, quiet list costs money here: and costs nothing natively, because the meter is subscribers rather than volume (based on published pricing).
- Every tier gets the same 10-day trial: so the whole evaluation has to fit inside one send cycle.
See the full breakdown TxtCart vs Seguno→
08. Recart
Managed SMS on a 12-month term, from $299 a month.
Recart sells execution rather than software. List growth is bundled with sending: OneClick Opt-in popups and unlimited contacts come on every tier, which is the point for stores whose list is not growing. Managed execution starts at the Scale tier, $999/mo for fully managed list growth and campaigns, while Starter is $299/mo for 23,000 SMS at $0.01 with email-only support. It is rated 4.7 out of 5 across 447 Shopify reviews, with migration and onboarding included at no cost (Recart Shopify listing).
Commitment is the catch: a 12-month term on SMS plans, with list-growth-only tiers running $200 to $800/mo on a quarterly term. Shopify Messaging has no term and no minimum, and uninstalling ends it, while TxtCart is month to month, cancel or pause anytime. (Sources: Recart pricing page and Shopify App Store listing, 2 August 2026.)
What to weigh: $299 a month buys execution rather than software, so the comparison is against an agency retainer, not against an app bill.
Shopify rating ★ 4.7
Key features
- List growth is bundled with sending: OneClick Opt-in popups and unlimited contacts come on every tier, which is the point for stores whose list is not growing (source: Recart pricing page)
- Managed execution starts at the Scale tier: $999/mo for fully managed list growth and campaigns (source: Recart pricing page)
- Shopify App Store rating: 4.7 out of 5 across 447 reviews, with migration and onboarding included at no cost
Recart’s Pricing
- Starter – $299/mo for 23,000 SMS at $0.01, with email-only support
- Scale – $999/mo for fully managed list growth and campaigns
- List-growth-only tiers – $200 to $800/mo on a quarterly term
- Commitment – a 12-month term on SMS plans
- Pricing from the Recart pricing page and Shopify App Store listing, 2 August 2026
Heads up
Based on user reviews
- Attribution is click-only on Starter: so the cheapest tier reports less than the tiers above it (based on published pricing).
- Strategy support is tiered: Starter buys sending and popups, and a dedicated success manager starts at $499/mo.

The Verdict
Klaviyo is the right answer when the complaint is email. Templates, segmentation, and segment-level reporting are what reviewers ask Shopify Messaging for, and Klaviyo ships all three. Omnisend does most of that for less on a smaller list, with both channels on one invoice.
TxtCart wins when the missing capability is a reply. The native app has no inbox behind its texts. That gap costs nothing until shoppers start texting back, and then it costs every conversation that dies unread. TxtCart takes over that lane: a shopper abandons, gets a text answering their actual question, and finishes checkout, while native email stays put.
Ready to test the SMS half? Start the TxtCart trial and compare recovered revenue against whatever the native flow pulled back last month.
