Key takeaways
- Klaviyo is the best fit for most stores at $0 to start, with Postscript next for Shopify-only SMS at a $49 monthly minimum, and Brevo cheapest for adding SMS to email at $9 a month plus credits.
- The single most important buying factor is the per-message math: plan prices run $9–$59 a month, but carrier fees, telecom surcharges and credit bundles decide the real bill.
- Only Klaviyo and Brevo offer genuinely free entry — Klaviyo with $5 of mobile messages a month, Brevo with SMS credits purchasable on its free plan.
- Every platform here needs a registered sending number — toll-free or 10DLC — before carriers will deliver marketing texts, so budget setup time as well as money.

Klaviyo
Best for: Ecommerce stores on Shopify, WooCommerce or BigCommerce that want email and SMS on one customer profile
Klaviyo is the SMS choice for stores already running email on it, because SMS shares the same customer profile, segments and flows as email — an abandoned-cart text and the follow-up email draw on the same purchase data. The free plan covers up to 250 active profiles with $5 of mobile messages a month, and paid Email starts at $20 a month plus SMS spend, billed at per-message rates that vary by destination.
The catch is that the bill grows two ways at once: the Email plan rises with active profiles, and SMS spend rises with sends, so a growing list pays more on both lines. There is no flat SMS bundle — messages deduct from a monthly spend tier. Buy Klaviyo when email and SMS should share one profile; buy Postscript when SMS alone is the revenue channel.
What we like
- Email and SMS share one customer profile, so segments and flows work across both channels
- Free plan covers up to 250 active profiles with $5 of mobile messages a month
- Deep store integrations: Shopify, WooCommerce, BigCommerce and Magento
- AI subject-line generator is included on the free plan, not held for paid tiers
Watch out for
- The bill grows two ways at once: the Email plan rises with active profiles and SMS spend rises with sends
- No flat SMS bundle — you pick a monthly spend tier and messages deduct from it at per-message rates
- Support on the free plan is email only for the first 60 days, and setup help is thinner than on paid plans
Postscript
Best for: Shopify stores that want SMS as a dedicated revenue channel with transparent per-message rates
Postscript is built only for Shopify SMS, and the focus shows: segments read Shopify customer tags and purchase history, checkout opt-ins and popups collect subscribers where they buy, and 26 automation triggers cover cart abandonment, browse abandonment, shipping and upsells. Starter carries a $0 platform fee with a $49 monthly minimum spend, and every rate is published — $0.009 per SMS and $0.045 per MMS on Starter, plus carrier fees passed through at cost.
The minimum is the thing to weigh. You pay $49 even in a month when you send nothing, and unused credits do not roll over, so seasonal stores pay for quiet months. Growth costs $100 a month and Professional $500, each with lower per-message rates. Pick Postscript when SMS is a serious revenue channel on Shopify; pick Klaviyo when the store runs on another platform.
What we like
- $0 platform fee with every rate published: $0.009/SMS and $0.045/MMS on Starter, plus carrier fees at cost
- Shopify-native segments, 26 automation triggers and checkout opt-ins built for store data
- Dedicated toll-free number included on every plan, with live chat and email support from Growth
- Pay after you send, with no prepaid balances, expiring credits or auto-upgrades
Watch out for
- Shopify only — other platforms need the SDK, and there is no native WooCommerce or BigCommerce app
- The $49 monthly minimum applies even in months when you send nothing
- Unused credits do not roll over, and the AI bundle is a separate $699/month plan
Attentive
Best for: Mid-market and enterprise ecommerce brands that want a managed SMS program with dedicated support
Attentive is the managed end of this list: instead of published tiers, you get a modular plan built around message volume, list size, channels and the AI tools you select, with a dedicated support team and strategic planning included. Pricing is usage-based with no credit system, so you pay for what you send, and the platform covers SMS, MMS, RCS, email and push with cross-channel journeys and the patented two-tap sign-up.
The trade-off is transparency. There is no published price to compare, so budgeting means a sales conversation, and the premium AI tools are priced separately from the base plan. Implementation typically takes about a month. Buy Attentive when the SMS program is big enough to deserve a team behind it; buy Postscript or Klaviyo when you want to start this week.
What we like
- Usage-based pricing with no credit system — you pay for what you actually send
- Patented two-tap sign-up plus cross-channel journeys across SMS, MMS, RCS, email and push
- Dedicated support team and strategic planning included, with 24/5 service
- Built-in TCPA and compliance tools with an enterprise-grade deliverability foundation
Watch out for
- No published price at all — you cannot budget Attentive without a sales conversation
- Premium AI tools are selected and priced separately, so the headline plan is not the whole bill
- Implementation typically takes about a month, longer than self-serve tools
Omnisend
Best for: Small and mid-size stores that want email plus SMS on a budget, with per-country SMS rates
Omnisend pairs email and SMS for stores that find Klaviyo dear: the free plan covers 250 contacts and 500 emails, Standard costs $16 a month for email, and SMS arrives on the Pro plan at $59 a month, or $41.30 with three months paid upfront. SMS pricing starts at $0.007 a message for high-volume US sends, with the rate varying by country and volume, and Pro adds AI agents for forms, send-time optimization and dynamic content.
The limit to watch is the plan gate: Standard and free accounts cannot send SMS at all, so the real entry price for texting is Pro, not the free plan or Standard. SMS credits are bought on top of the plan price. Pick Omnisend when email and SMS should live together on a budget; pick Brevo when SMS alone is the job.
What we like
- SMS from $0.007 a message at the high-volume US starting rate, bought as credits on Pro
- Free plan covers 250 contacts and 500 emails, so the email side can be tested at $0
- AI agents for forms, chat, dynamic content and send-time optimization on Pro
- 24/7 live chat and email support on every plan, including free
Watch out for
- SMS is a Pro-plan add-on — the cheaper Standard plan and the free plan do not send SMS
- The $41.30 Pro figure is a 3-months-upfront promotion; the regular monthly price is $59
- SMS rates vary by country and volume, so the $0.007 starting rate is a high-volume US figure, not a flat rate
Brevo
Best for: Stores that want the cheapest way to add SMS to an email program, paying only for credits used
Brevo is the cheapest way to add SMS to an existing email program: Starter costs $9 a month for 5,000 emails, and SMS runs on prepaid credits bought separately — from $1.09 per 100 US messages, about $0.0109 each — on any plan, including the free plan. A US text uses one credit, credits never expire per Brevo's pricing FAQ, and the same account also covers email, WhatsApp, push and a basic CRM.
The catch is that the plan price sends nothing on its own: every text is a credit purchase on top, so the bill is $9 plus whatever you send. WhatsApp credits need the Professional plan, and the pricing page did not render its prices in our check, so the figures here rest on November 2026 reads. Pick Brevo when sends are occasional and every dollar counts.
What we like
- SMS credits from $1.09 per 100 US messages, purchasable on any plan including Free
- Starter is $9 a month for 5,000 emails, the cheapest entry plan in this list
- Credits never expire according to Brevo's pricing FAQ, so small sends do not go to waste
- Email, SMS, WhatsApp, push and a basic CRM in one account
Watch out for
- SMS credits are a separate purchase — the $9 plan price alone sends no texts
- The pricing page did not render plan prices in our check, so the $9 figure rests on November 2026 reads of the page
- WhatsApp credits need the Professional plan, and SMS credit terms differ between the pricing file and the help pages
SimpleTexting
Best for: Small teams that want flat, predictable SMS pricing with every feature on every plan
SimpleTexting is the plain, predictable option: one credit buys one standard SMS, MMS costs three credits, and every plan carries the same features — mass texting, two-way messaging, drip campaigns, MMS, AI Assist, API access and analytics. The entry plan costs $29 a month for 500 credits on a toll-free number, with unlimited contacts, unlimited keywords, three user seats and rollover credits that carry unused messages into the next month.
The number is the part to price carefully. The pricing page defaults to a $39 estimate because a local number adds $10 a month plus a $4 one-time carrier registration fee; the toll-free number is free, which is how the entry price becomes $29. Extra seats cost $20 a month each. Pick SimpleTexting when a small team wants one flat bill and no feature gates.
What we like
- Every feature on every plan — you pay for credits, not for unlocking tools
- Flat $29 a month for 500 credits on a toll-free number, with rollover credits
- Incoming SMS is free, and live support runs seven days a week on every plan
- Unlimited contacts and unlimited text-to-join keywords on all plans
Watch out for
- The pricing page defaults to a $39 local-number estimate — the $29 toll-free entry is easy to miss
- A local number adds $10 a month plus a $4 one-time carrier registration fee
- MMS costs 3 credits and extended messages cost 2, so media-rich sends burn the allowance three times faster
EZ Texting
Best for: Small businesses that want fast setup, a local number and AI writing help at a low entry price
EZ Texting sells speed: Launch costs $25 a month billed monthly, or $20 billed annually, and includes a local textable number, 500 monthly credits, unlimited contacts, keywords, QR codes, signup forms and a team inbox, with setup inside one business day and carrier registration handled at no extra cost. AI Compose and AI Reply sit on every plan, along with a Shutterstock media library for MMS images.
Two costs sit outside the headline price. Launch carries a $5 a month telecom fee, and every plan starts with only 500 credits — bigger sends mean buying credit bundles at checkout, with overage at $0.04 a credit on Launch. Only one user seat is included. Pick EZ Texting when the program must be live this week and the list is small.
What we like
- Launch is $25 a month ($20 billed annually) with a local textable number included
- Setup inside one business day, with carrier registration handled at no extra cost
- AI Compose and AI Reply plus a Shutterstock media library on every plan
- Unused credits roll over for one extra billing cycle while the subscription stays active
Watch out for
- Launch adds a $5 a month telecom fee that the headline $25 price does not include
- Every plan starts with just 500 credits — bigger sends mean buying credit bundles at checkout
- Only one user seat is included; extra seats cost $10 a month each
Textedly
Best for: Small businesses that want every feature on day one and text-to-pay built in
Textedly gives every plan the full toolkit on day one: mass texting, two-way messaging, text-to-pay through Stripe, Google review requests, MMS, the AI composer and premium support, with unlimited contacts and no long-term contracts. Basic costs $29 a month for 500 messages, and annual billing adds 20% more texts a month rather than cutting the price, which suits stores whose volume swings by season.
The surcharge is the part to add before comparing: an $8 a month telecom fee sits on top of every plan, so Basic really costs $37 a month, and extra texts cost $30 per 500. A free toll-free number and a free 10DLC number are included. Pick Textedly when text-to-pay and review requests matter as much as the campaigns themselves.
What we like
- Every feature on every plan, including text-to-pay, review requests and the AI composer
- Free toll-free and 10DLC numbers included, with built-in TCPA and opt-in management
- Incoming messages are always free, and there are no long-term contracts
- Annual billing adds 20% more texts a month instead of a percentage discount
Watch out for
- An $8 a month telecom surcharge sits on top of every plan price
- Plans are priced by message volume only, so a small list that texts often pays the same as a big list
- Extra texts cost $30 per 500, which is dearer than the per-message rate inside the plans
SlickText
Best for: Small businesses and nonprofits that want rollover credits and a shared team inbox
SlickText is the steady small-business option: $29 a month buys 500 credits, every plan includes all tools — mass texting, workflows, the shared inbox, list-growth tools and analytics — and unused credits roll over for one term instead of vanishing at month-end. Annual plans give two months free, nonprofits get 20% off any standard plan, and sending covers the US and Canada across 10DLC, toll-free, short code and RCS numbers.
The limits are the expiry window and the premium channels: rollover lasts one term only, RCS needs a $500 setup fee plus $200 a year in maintenance, and short codes are priced on request. Carrier fees pass through at cost on top of the plan. Pick SlickText when a small team wants one simple plan and a shared inbox.
What we like
- $29 a month for 500 credits with rollover texts on monthly and annual plans
- All tools included in every plan, including workflows and the shared inbox
- Annual plans give two months free, and nonprofits get 20% off any standard plan
- US and Canada sending with four number types: 10DLC, toll-free, short code and RCS
Watch out for
- Unused credits roll over for only one term, then they expire
- RCS costs a $500 one-time setup fee plus $200 a year in maintenance
- Short codes are a separate, dearer purchase, and the pricing page prices them only on request
Twilio
Best for: Teams with developers that want to build SMS into their own app or workflow at wholesale rates
Twilio is not a marketing tool but the raw material the others are built from: an API that sends SMS, MMS, RCS and WhatsApp, priced per phone number, per message segment and per-segment carrier fee, with no platform fee and no monthly minimum. US SMS and RCS start at $0.0083 per segment plus carrier fees, numbers start at $1.15 a month, and Studio flows, link shortening and scheduling come in the API.
The price of that freedom is the build. There is no campaign interface, no list-growth popup and no compliance concierge — opt-in handling, 10DLC registration and every workflow are code your team writes and maintains. Pick Twilio when developers own the messaging roadmap; pick anything above it when marketers do.
What we like
- No platform fee at all — US SMS and RCS start at $0.0083 per segment plus carrier fees
- Phone numbers from $1.15 a month, so a small test program costs a few dollars
- Studio flows, link shortening, scheduling and global compliance tooling in the API
- Scales to any volume with committed-use contracts for high-volume senders
Watch out for
- No campaign interface — every send, schedule and segment is code you write and maintain
- Carrier fees sit on top of the $0.0083 segment rate and vary by carrier and route
- Compliance, opt-in handling and 10DLC registration are your job, not the platform's
The best sms marketing platforms for ecommerce do more than send texts: they tie each message to an order, a cart or a customer segment, so a flash sale, a back-in-stock alert or an abandoned cart turns into revenue instead of noise. We ranked the ten tools below by fit for the most common buyer — a store owner who wants SMS working with their store, not beside it — and every price was checked on the vendor's own pricing page on November 5, 2026.
How to choose the best sms marketing platforms for ecommerce
- Start from your store platform. Postscript is Shopify-only, so a WooCommerce or BigCommerce store should shortlist Klaviyo, Omnisend or Brevo instead — all three connect to more than one store platform.
- Read the per-message rate, not just the plan price. A $9 plan that charges $0.0109 a text can cost more than a $29 plan with cheaper credits once you send thousands of messages a month.
- Check what the free plan actually sends. Klaviyo's free plan includes $5 of mobile messages a month, and Brevo sells SMS credits on its free plan — but Omnisend's free plan cannot send SMS at all.
- Count the surcharges before you compare. Carrier fees sit on top of nearly every rate here, and EZ Texting adds a $5 telecom fee while Textedly adds $8, so two $29 plans can bill $29 and $37.
- Check the compliance tooling. Every store needs a registered sending number and provable opt-in; tools that handle 10DLC or toll-free verification for you save weeks of back-and-forth with carriers.
SMS is one channel in a retention stack, not the whole stack. If email is the other half, our guide to email marketing platforms for ecommerce covers that side. And before you publish landing pages for your SMS campaigns, run your titles through the free SERP snippet preview tool — it shows exactly how the title and description will look in Google.
Whatever you shortlist, try it with a real segment before you pay. The free plans and trials in this list are long enough to send one genuine campaign — your list, your offer, your sending number — and that campaign tells you more than any review can. Check two things in the trial: that messages arrive from a number your customers recognize, and that unsubscribes and replies land somewhere your team will actually see them.
SMS marketing platforms for ecommerce pricing: what you will actually pay
Take a store with 5,000 subscribers that sends two campaigns a month — 10,000 SMS in total. On published rates, the month costs $123 on Postscript Starter ($90 in messages at $0.009 each, plus $33 in carrier fees at $0.00330 each, above the $49 minimum), $118 on Brevo ($9 for Starter plus 10,000 credits at $0.0109 each), $129 on Omnisend Pro ($59 plus 10,000 messages at the $0.007 starting rate), $307 on Textedly ($299 for the 10,000-message tier plus the $8 surcharge) and $319 on SlickText (its 10,000-credit tier). Twilio lands near $84 before carrier fees (10,000 segments at $0.0083 plus a $1.15 number), and Attentive cannot be priced from its page at all.
Two of those numbers need adjusting before they are real. First, SimpleTexting's $29 plan covers only 500 credits, so 10,000 messages means a much higher tier, not the entry plan. Second, EZ Texting's Launch plan also starts with 500 credits, so at its $0.04 overage rate the same 10,000 messages cost $25 plus $380 in overage plus the $5 telecom fee — $410 in total. Klaviyo is the hardest to pin down: Email starts at $20 a month, and SMS spend is tiered, so the same 10,000 texts cost whatever spend tier they land in.
Annual billing cuts the bill on several tools here: EZ Texting Launch drops from $25 to $20 a month, SlickText annual plans give two months free, Textedly adds 20% more texts instead of a discount, and SimpleTexting takes 20% off the credits line. Omnisend's $41.30 Pro figure is a three-months-upfront promotion, not an annual rate. One more cost to check before you commit: a second store is a second account on most tools here, and MMS costs two to three times a plain SMS on nearly every plan — a campaign with images should be budgeted as MMS, not SMS.
Know the difference: credits, subscriptions and pay-as-you-go
The confusion in this category is that three different billing models all look like a monthly price. A subscription bundles an allowance into a flat fee — SimpleTexting's $29 for 500 credits, Textedly's $29 for 500 messages. A credit bundle is prepaid: you buy messages upfront and spend them down, and the expiry rules decide whether leftovers survive — SlickText, SimpleTexting and EZ Texting roll unused credits over for one term, while Postscript's do not roll over at all. Pay-as-you-go has no allowance and no expiry: Twilio and Attentive bill each message after it is sent, so a quiet month costs almost nothing and a big month costs exactly what it costs.
There is a second, quieter confusion: the plan price is never the whole bill. Carrier fees sit on top of nearly every rate in this list, telecom surcharges add $5–$8 a month on EZ Texting and Textedly, and a local number can add $10 a month plus a registration fee on SimpleTexting. An SMS is also not always one unit: a message over 160 characters splits into segments, MMS costs two to three credits on most plans, and a 1,600-character MMS is a different product from a 160-character SMS. Budget the message type you will actually send, not the cheapest unit on the page.
A third distinction worth knowing is the sending number itself. Marketing texts in the US now travel on registered routes: a 10DLC local number or a verified toll-free number, each with its own registration step and fee. Unregistered traffic gets filtered or blocked, so the number setup is part of the purchase, not an afterthought — and it is the reason several tools in this list quote setup times in days rather than minutes.
Quick comparison: tool type by need
| Buyer | Best pick | Why |
|---|---|---|
| Store already running Klaviyo email | Klaviyo | Same profile for email and SMS, free to start with $5 of messages a month |
| Shopify-only SMS program | Postscript | Shopify-native segments and triggers, $0 platform fee, $49 monthly minimum |
| Managed enterprise program | Attentive | Usage-based pricing with a dedicated team, no published price to compare |
| Cheapest SMS add-on | Brevo | Credits from $1.09 per 100 US messages, even on the free plan |
| Flat, predictable pricing | SimpleTexting | Every feature on every plan, $29 a month for 500 credits |
| Fastest setup | EZ Texting | Live inside one business day, local number included, from $25 a month |
| Developer-built messaging | Twilio | No platform fee, $0.0083 per US segment plus carrier fees |
Mistakes to avoid
- Budgeting on the plan price. The $9–$59 plan figures in this list are the floor, not the bill. Carrier fees, telecom surcharges, number fees and credit top-ups sit on top — price the month from the worked example above, not the pricing page headline.
- Buying credits that expire. Postscript's unused credits do not roll over, so a seasonal store pays for quiet months twice over. SlickText, SimpleTexting and EZ Texting roll credits for one term — check the expiry rule before you buy a bundle.
- Picking a Shopify-only tool for another platform. Postscript has no native WooCommerce or BigCommerce app. If the store ever moves platforms, the SMS program moves with it — or gets rebuilt.
- Leaving number registration until launch week. 10DLC and toll-free verification take days, and unregistered traffic gets filtered. Register the number the week you choose the tool, not the week you send the first campaign.
- Texting without provable consent. Marketing texts need express opt-in, and carriers enforce it. A list bought, borrowed or scraped will get the number flagged faster than any campaign can pay for itself.
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 annual-billing figure where the page lists one, and we ranked the tools by fit for the most common buyer — a store owner who wants SMS working with their store — not by brand size. Three figures need a sourcing note. Brevo's pricing page did not render its plan prices in our check, so its $9 Starter figure and $1.09-per-100 SMS credit rate come from November 2026 reads of Brevo's own pricing page and calculator. Klaviyo's paid Email figure of $20 a month comes from third-party reads of Klaviyo's pricing calculator; the live page crawl showed the free-plan details only. SimpleTexting's $29 toll-free entry is corroborated by September–October 2026 reads of its pricing page, which defaults to the $39 local-number estimate. Attentive publishes no price, so it is shown as a custom quote, and Twilio is pay-as-you-go with no monthly plan. Yotpo SMS was left out of this list: its Shopify listing is no longer available and no current vendor price could be verified. Ratings come from G2 pages opened on 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 your most engaged segment. Check that messages arrive from a recognizable number, that replies land in an inbox your team reads, and that unsubscribes are honored automatically before you commit to a year. If the store is sorted but new customers are not finding you, our monthly SEO service handles the visibility side — or compare email options in our guide to email marketing platforms for ecommerce.

Frequently asked questions
What is the best SMS marketing platform for ecommerce?
Klaviyo is the best fit for most stores, because email and SMS share one customer profile and the free plan covers up to 250 profiles. Postscript is the better pick for a Shopify-only SMS program, and Attentive suits larger brands that want a managed program with dedicated support.
How much does SMS marketing for ecommerce cost?
Plan prices run $9–$59 a month, but the real bill is plan plus messages plus fees. A store sending 10,000 US texts a month pays about $118 on Brevo, $123 on Postscript and $307 on Textedly, before any annual discount — the spread comes from per-message rates, not plan prices.
Is there a free SMS marketing platform for ecommerce?
Only in a limited sense. Klaviyo's free plan includes $5 of mobile messages a month, and Brevo lets you buy SMS credits on its free plan. Every other tool here is paid or trial-only, so a store that texts regularly should budget from the entry plan, not the free tier.
What is the difference between SMS credits and a monthly plan?
A monthly plan bundles an allowance into a flat fee, credits are prepaid bundles you spend down, and pay-as-you-go bills each message after you send it. Credits can expire or roll over depending on the vendor, while pay-as-you-go has no allowance to waste — but also no cap on the bill.
Do I need a separate SMS tool if I already use Klaviyo or Omnisend?
No. Klaviyo includes SMS on its free and paid plans, and Omnisend adds SMS credits on its Pro plan, so both cover email and texting in one account. A separate tool only makes sense when you want a dedicated SMS channel, like Postscript on Shopify, or wholesale API rates from Twilio.
What are carrier fees and 10DLC registration?
Carrier fees are small per-message surcharges the mobile networks charge, passed through at cost by most vendors — about $0.0033 per US SMS on Postscript. 10DLC registration is the approval process for sending from a local 10-digit number; toll-free numbers have their own verification step instead.
Can I switch SMS platforms later?
