The best SMS marketing platforms ROI ecommerce

#1

Klaviyo

Best for: Ecommerce stores on Shopify that want email and SMS in one platform with revenue attribution

★★★★★★★★★★4.6/5 on G2 (1,360 reviews, checked Nov 2026)

Visit klaviyo.com

Starting price$35/month (Email + SMS, 251–500 profiles; SMS add-on from $15/month)

Free planYes — free plan (250 profiles, $5 of mobile messages a month)

Klaviyo is the default pick for ecommerce SMS because email and text live in one platform: one list, one segment builder and one revenue report, so a text campaign and an email campaign never compete for the same customer. Email plus SMS costs $35 a month for 251 to 500 profiles, and the free plan covers 250 profiles with $5 of mobile messages a month.

The pricing catch is that SMS is metered on top of the email plan, so the bill rises with every send — 5,000 US texts cost about $70 on top of the email price. There is no annual discount, so the monthly figure is the whole story. Buy Klaviyo when email and SMS should share one list and one report; buy Postscript when SMS is the main revenue channel and email lives elsewhere.

What we like

• Email and SMS share one list, one segment builder and one revenue report
• Pre-built flows for abandoned cart, welcome and win-back are ready on day one
• Carrier fees are included in the per-message SMS rate, so the bill is easy to forecast
• More than 350 integrations, with the deepest Shopify connection in this list

Watch out for

• SMS is metered on top of the email plan, so the bill grows with every send
• No annual discount — the monthly price is the price all year
• Support on the free plan is email-only for the first 60 days

#2

Postscript

Best for: Shopify brands that want SMS as a dedicated revenue channel with human agents closing sales over text

★★★★★★★★★★4.8/5 on G2 (161 reviews, checked Nov 2026)

Visit postscript.io

Starting price$0/month platform fee ($49/month minimum spend; $0.009 per US SMS)

Free planNo — 30-day free trial

Postscript does one thing — SMS for Shopify stores — and the focus shows in the pricing: a $0 platform fee with a $49 monthly minimum spend, and $0.009 per US SMS on the Starter plan, the lowest per-message rate in this list. Growth costs $100 a month at $0.008 per SMS, and Professional costs $500 at $0.007.

The catch is the carrier fee, passed through at about $0.0033 per SMS on top of the message rate, and the Shopify-only limit — other platforms cannot use it at all. SMS Sales, where real agents close sales over text, is the standout feature for stores that treat text as a revenue channel. Pick Postscript when the store runs on Shopify and SMS is the main retention channel.

What we like

• Transparent published pricing — $0 platform fee with a $49 monthly minimum spend
• Lowest per-message rate here at $0.009 per US SMS on the Starter plan
• SMS Sales puts real human agents on text conversations to close orders
• Unlimited segments, a dedicated toll-free number and checkout opt-ins on every plan

Watch out for

• Shopify-only — no WooCommerce, BigCommerce or custom store support
• Carrier fees are passed through on top of the per-message rate
• The AI sales agent is a separate $699/month add-on, not part of any plan

#3

Attentive

Best for: Large ecommerce brands with six-figure SMS budgets that want AI personalization and white-glove onboarding

★★★★★★★★★★4.5/5 on G2 (1,483 reviews, checked Nov 2026)

Visit attentive.com

Starting priceCustom quote (no published prices; usage-based on list size and volume)

Free planNo — free trial for eligible businesses

Attentive is the enterprise pick in this list: patented two-tap sign-up, AI send-time optimization on every tier, and SMS, email, RCS and push under one customer profile. It is built for brands that treat text as a major revenue channel, with white-glove onboarding and deliverability infrastructure for very high volumes.

The price is a custom quote — Attentive publishes no figures, and contracts commonly carry quarterly minimums of $2,000 to $3,000 with no rollover, plus overage penalties above the committed volume. That makes it the wrong buy for a small store and the right one for a large brand. Shortlist Attentive when the SMS budget is five figures and personalization is the goal.

What we like

• Patented two-tap mobile sign-up grows lists faster than standard forms
• AI Essentials — send-time optimization and journeys — is included on every tier
• SMS, email, RCS and push in one platform with one customer profile
• Best-in-class deliverability and compliance infrastructure for high-volume senders

Watch out for

• No published prices — every figure needs a sales conversation
• Contracts commonly carry quarterly minimums with no rollover of unused volume
• Overage penalties of 20–50% apply above the committed volume

#4

Omnisend

Best for: Growing Shopify and WooCommerce stores that want email, SMS and popups in one cheap platform

★★★★★★★★★★4.6/5 on G2 (1,256 reviews, checked Nov 2026)

Visit omnisend.com

Starting price$59/month (Pro, up to 2,500 contacts; SMS bought separately from $0.007/message)

Free planNo — SMS requires the Pro plan ($59/month)

Omnisend is the value all-in-one in this list: email, SMS, push and popups in one platform built for ecommerce, with pre-built abandoned cart and welcome flows ready the same day you connect the store. The free plan covers 250 contacts and 500 emails a month, Standard starts at $16 a month, and Pro starts at $59 with unlimited emails.

The catch for SMS buyers is that new subscribers must be on Pro to buy SMS credits — Standard has no SMS access, and the credits are billed separately from $0.007 per message. The $79-per-$1 figure Omnisend reports is a vendor claim, not an independent measurement, so treat it as marketing. Buy Omnisend when one cheap platform should run email and SMS together.

What we like

• Pro includes unlimited emails plus AI tools like Forms AI and Reports AI
• Pre-built abandoned cart, welcome and win-back workflows ready the same day
• 24/7 live chat and email support on every plan, including the free plan
• Omnisend reports its merchants make an average of $79 for every $1 they spend

Watch out for

• SMS is not available on Standard — new subscribers must pay for Pro at $59/month
• SMS credits are bought separately at volume rates from $0.007 per message
• Reporting is thinner than Klaviyo's, and advanced reports wait for Pro

#5

Yotpo SMS & Email

Best for: Shopify stores already using Yotpo reviews or loyalty that want SMS added to the same retention suite

★★★★★★★★★★4.3/5 on G2 (266 reviews, checked Nov 2026)

Visit yotpo.com

Starting price$19/month (Starter; free to install, SMS $0.0182 per message pay as you go)

Free planYes — free to install (SMS pay as you go at $0.0182/message)

Yotpo SMS & Email fits stores already inside the Yotpo retention suite: reviews, loyalty, referrals and SMS share one customer record, so a text can reference a review or a loyalty balance without a second integration. It is free to install with 1,000 free emails a month, and SMS is pay as you go at $0.0182 per message.

The Starter plan costs $19 a month and cuts the SMS rate to $0.0164, Pro costs $59 and adds AI segments and smart send times, and Premium costs $199 with a dedicated success manager. The per-message rate is the highest here, so heavy senders pay more than on Postscript or Omnisend. Pick Yotpo when the store already runs Yotpo reviews or loyalty.

What we like

• Free to install with 1,000 free emails a month and pay-as-you-send SMS
• One platform for reviews, loyalty, referrals and SMS — one customer record
• No contact-based pricing: you pay for what you send, not for list size
• Starter at $19/month cuts the SMS rate to $0.0164 per message

Watch out for

• SMS is always pay as you go — there is no bundled SMS allowance on any plan
• The per-message rate of $0.0182 is the highest in this list
• AI-powered segments and smart send times wait for the $59/month Pro plan

#6

SlickText

Best for: Small teams that want every feature on every plan and credits that roll over

★★★★★★★★★★4.8/5 on G2 (1,894 reviews, checked Nov 2026)

Visit slicktext.com

Starting price$29/month (500 credits; all features on every plan)

Free planNo — 14-day free trial

SlickText keeps pricing simple: eight tiers from $29 a month for 500 credits to $939 for 50,000, and every plan includes every feature — mass texts, automations, loyalty programs, popups and the shared inbox — with unlimited contacts and free incoming texts. Unused credits roll over, which matters for stores that text heavily around sales and lightly between them.

The edges are the add-ons: RCS costs $500 to set up plus $200 a year, and a dedicated short code needs at least the $319 plan. There is no email channel, so email campaigns need a second tool. Pick SlickText when the team wants one SMS tool with no feature gates and no per-seat fees.

What we like

• Every feature ships on every plan — no upsells for automation, MMS or keywords
• Unused credits roll over, which most rivals at this price do not offer
• Unlimited contacts and free incoming texts on every plan
• Highest G2 rating in this list at 4.8/5 from more than 1,800 reviews

Watch out for

• RCS messaging costs $500 to set up plus $200 a year — far above the entry price
• Short codes need at least the $319/month plan
• No email channel, so a second tool is needed for email campaigns

#7

SimpleTexting

Best for: Small teams sending mass texts and two-way replies who want a clean dashboard and an API

★★★★★★★★★★4.7/5 on G2 (644 reviews, checked Nov 2026)

Visit simpletexting.com

Starting price$29/month (500 credits; registered local number adds $10/month)

Free planNo — 14-day free trial

SimpleTexting is the easy all-rounder: mass campaigns, autoresponders, drip sequences, MMS and polls in one clean interface, with unlimited contacts and keywords on every plan so a growing list never forces an upgrade by itself. Plans run from $29 a month for 500 credits to $909 for 50,000, with a 20% discount for annual billing.

The real entry cost is $39 a month, not $29, because a registered local number adds $10 a month, plus a $4 one-time carrier registration fee. Extra credits cost $0.055 each, and the platform serves the US and Canada only. Pick SimpleTexting when the team wants straightforward mass texting with two-way replies and an API.

What we like

• Unlimited contacts and keywords on every plan, so list growth never forces an upgrade
• Free incoming texts and a shared two-way inbox on the entry plan
• Mass campaigns, autoresponders, drip sequences, MMS and polls in one interface
• An API is included for teams that want to send texts from their own systems

Watch out for

• A registered local number adds $10/month, so the real entry cost is $39/month
• Extra credits cost $0.055 each and carrier fees are passed through at cost
• US and Canada only — no international sending

#8

EZ Texting

Best for: Beginners who want a flat monthly credit plan and quick setup with phone support

★★★★★★★★★★4.5/5 on G2 (744 reviews, checked Nov 2026)

Visit eztexting.com

Starting price$25/month (Launch, billed monthly; $20/month billed annually, plus $5 telecom fee)

Free planNo — free trial available

EZ Texting sells predictability: a flat monthly price with 500 credits included, carrier registration and incoming messages in the plan price, and phone support on every tier. Launch costs $25 a month, or $20 billed annually, Boost costs $75 and Scale costs $125, and Enterprise starts at $3,000 a month.

The oddity is that all three self-serve tiers include the same 500 credits a month — upgrading from Launch to Boost or Scale buys features and contact capacity, not sending volume, and extra credits cost $0.04 each on Launch. Only one seat is included, and extra seats cost $10 a month each. Pick EZ Texting when a flat, predictable bill matters more than per-message price.

What we like

• Flat monthly price with 500 credits included, so the bill is predictable
• Carrier registration and incoming messages are included in the plan price
• All plans include phone and chat support, QR codes and signup forms
• Annual billing cuts Launch from $25 to $20 a month

Watch out for

• All three self-serve tiers include the same 500 credits — upgrading buys features, not volume
• Launch carries a $5/month telecom fee on top of the $25 plan price
• Extra seats cost $10/month each and only one seat is included

#9

TextMagic

Best for: Occasional senders who want pay-as-you-go pricing with no monthly subscription or contract

★★★★★★★★★★4.4/5 on G2 (129 reviews, checked Nov 2026)

Visit textmagic.com

Starting pricePay as you go ($0.049 per SMS; $20/month floor for number + 10DLC after month 1)

Free planNo — 30-day free trial

TextMagic is the pay-as-you-go pick: no monthly subscription, no contract, and credits that never expire. Outbound SMS costs $0.049 per message in the US, inbound SMS is free, and MMS is $0.08 per message. It works in more than 200 countries, the widest reach in this list, and the Bring Your Own CPaaS option cuts the outbound rate to $0.01 per message part.

The catch is the floor after month one: a dedicated number and 10DLC campaign registration are free for the first month, then $10 a month each, so the real monthly floor is $20 even before a single text is sent. At $0.049 per message it is also the most expensive per SMS here. Pick TextMagic when sending is occasional and a subscription would sit idle.

What we like

• No monthly subscription — buy credits when you need them and they never expire
• Works in more than 200 countries, the widest reach in this list
• Inbound SMS is free and MMS is a flat $0.08 per message
• Bring Your Own CPaaS cuts the outbound rate to $0.01 per message part

Watch out for

• After the first free month, a number and 10DLC registration cost $10/month each — a $20 floor
• The $0.049 per-message rate is the most expensive per SMS in this list
• Professional and Connect plan prices are not published — sign-up is required to see them

The best sms marketing platforms roi ecommerce stores use turn a text into a sale, not just a notification. We ranked the nine tools below by fit for the most common buyer — a US online store that wants every text to pay for itself — starting with the all-in-one platforms and ending with the pay-as-you-go options, and every price was checked on the vendor's own pricing page on November 5, 2026.

How to choose the best sms marketing platforms roi ecommerce

• Price the message, not just the plan. A $29 plan that includes 500 credits costs more per text than a $0 platform fee at $0.009 a message once you send real volume. Work out your cost per SMS at your actual monthly volume before comparing headline prices.
• Check what the entry plan actually includes. Omnisend Standard has no SMS at all for new subscribers, Attentive hides AI features behind custom tiers, and Yotpo charges for every SMS on every plan. The plan fee is only part of the bill.
• Count the fees around the price. Carrier fees, number rentals, 10DLC registration and overage rates all sit outside the headline figure. SimpleTexting adds $10 a month for a local number, EZ Texting adds a $5 telecom fee, and TextMagic adds $20 a month after month one.
• Match the tool to your store platform. Postscript and Yotpo SMS & Email are built for Shopify, Klaviyo and Omnisend cover Shopify and WooCommerce, and SlickText, SimpleTexting and EZ Texting work for any US business with a phone list.
• Track revenue per text, not opens. Tag every link in every text with the free UTM builder so each campaign's revenue shows up in your analytics. Opens tell you the text arrived; revenue per SMS tells you whether it paid.

SMS is one system in your stack, not the whole stack. If the store also needs to be found on Google, our monthly SEO service handles the visibility side — or compare providers in our guide to ecommerce marketing companies. Before you commit to any tool, run its free plan or trial with real subscribers and one real campaign, and check two things: that the revenue report ties sales back to the text that drove them, and that the per-message cost at your volume still leaves a margin after the offer.

SMS platform pricing: what you will actually pay

Take a store with 2,500 subscribers that sends two texts a month — 5,000 texts a month. On list prices, the monthly cost is about $62 on Postscript (5,000 texts at $0.009 plus about $17 in carrier fees), $90 on Klaviyo ($20 for the email plan at 500 profiles plus about $70 for 5,000 texts), $94 on Omnisend Pro ($59 plus 5,000 texts at $0.007), $101 on Yotpo Starter ($19 plus 5,000 texts at $0.0164), $169 on SlickText (the 5,000-credit plan), $210 on EZ Texting (Launch at $25 plus 4,500 extra credits at $0.04 plus the $5 telecom fee), $249 on SimpleTexting (the 7,500-credit plan at $239 plus the $10 number fee), and $265 on TextMagic (5,000 texts at $0.049 plus the $20 floor).

Over a year, that is about $744 on Postscript, $1,080 on Klaviyo, $1,128 on Omnisend Pro, $1,212 on Yotpo Starter, $2,028 on SlickText, $2,520 on EZ Texting, $2,988 on SimpleTexting and $3,180 on TextMagic. The same 5,000 texts a month cost $744 at the cheap end and $3,180 at the dear end — a $2,436 gap that comes entirely from the pricing model, not from features. Attentive is not in this comparison because it publishes no prices.

Three costs sit outside every number above. First, the number: a dedicated short code costs about $750 a month on Postscript and $1,000 a month on SimpleTexting, so most stores should start on a toll-free number. Second, 10DLC registration: budget $10 a month and a few days of setup delay. Third, MMS: a picture message costs 3 credits on SlickText, SimpleTexting and EZ Texting, so a campaign with images costs three times the SMS price on those platforms. If email is part of the same program, the email side is already covered in our guide to the best email marketing platforms for ecommerce.

The cheapest per-message rate is not always the cheapest bill. Postscript is cheapest at 5,000 texts a month, but a store sending only 500 texts a month pays $49 on Postscript against $25 on EZ Texting and about $45 on TextMagic. Work out the cost at your own volume — the volume where the ranking flips is usually between 1,000 and 2,000 texts a month — and re-check it every quarter, because list growth moves you across credit tiers without warning.

Know the difference: SMS ROI vs email ROI

The confusion in this category is between a channel that is read and a channel that is cheap. SMS is read fast — texts are usually opened within minutes — but every single text costs money, while email costs almost nothing per send once the plan is paid. That flips the ROI math: an email campaign can afford a weak offer because the send is nearly free, while a text campaign with a weak offer loses money on every message.

There is a second confusion: revenue attributed to SMS is not the same as revenue caused by SMS. Most platforms report the revenue from customers who received a text and then bought, which includes people who would have bought anyway. The honest measure is a holdout test — send to nine in ten subscribers and hold back one in ten, then compare what the two groups spend. Klaviyo and Attentive support holdout testing; the credit-based tools in this list generally do not, so their revenue reports should be read with that in mind.

A third distinction worth knowing is list growth versus list quality. A list built with a strong incentive — 15% off for joining — grows fast and texts cheaply, but it fills with discount hunters who rarely buy at full price. A list built slowly from checkout opt-ins grows slower and costs more per subscriber to acquire, but it converts better. The platforms that report the highest ROI figures are usually reporting on the second kind of list, not the first.

Quick comparison: tool type by need

Mistakes to avoid

• Budgeting on the plan price alone. The plan fee is often the smaller half of the bill. A $29 plan with 500 credits costs $249 a month once you need 5,000 texts, and carrier and number fees sit on top of that.
• Buying credits that expire. Some platforms sell credits that vanish at month-end, while SlickText lets unused credits roll over. If you text heavily around sales and lightly between them, rollover is worth real money.
• Sending without a holdout test. Platform revenue reports credit SMS with sales that would have happened anyway. Hold back one in ten subscribers and compare spending before you call a campaign profitable.
• Ignoring the 10DLC delay. US carriers require brand and campaign registration before a business number can send marketing texts. Registration takes days, so start it before the first campaign is scheduled, not after.
• Texting the whole list every time. The fastest way to burn a list is to text everyone about everything. Segment by purchase history and send the offer only to the subscribers it fits — the per-message cost makes every irrelevant text a direct loss.

How we chose

We checked each vendor's own pricing page on November 5, 2026 and recorded the starting price exactly as shown, including the per-message rate and the fees around it, and we ranked the tools by fit for the most common buyer — a US online store that wants every text to pay for itself — not by brand size. Klaviyo's $35 Email plus SMS figure and its $70 cost for 5,000 texts come from the vendor's own pricing page as read in October 2026, confirmed by several independent reads that agree; Yotpo's prices come from its Shopify App Store listing, where the vendor publishes them. Attentive publishes no prices, so it appears here as a custom quote and is left out of the price chart. Ratings are G2 scores from the vendors' G2 pages, checked November 5, 2026. No vendor paid for a place in this list, and none of the links here are affiliate links.

What to do next

Start with the free plan or trial of your top pick and send one real campaign to a real segment — an abandoned-cart flow or a flash-sale text to recent buyers. Measure revenue per SMS sent against the full cost, plan fee included, and compare it with the same offer sent by email. If texting pays, scale the list with checkout opt-ins and a welcome flow; if it does not, the offer or the segment is the problem, not the channel. If the store is sorted but new customers are not finding it, our monthly SEO service handles the visibility side. Once your tools are in place, find out what's holding your rankings back.
