website: https://www.klaviyo.com best_for: Stores that want email and SMS orchestrated from one platform starting_price: See website free_plan: Yes (free tier) pros: Unified customer profile across email and SMS, deep Shopify integration, generous free tier cons: Costs scale with contacts and sends, SMS treated as an add-on to an email-first platform
Klaviyo is the email platform most ecommerce stores already know, and its SMS product rides on the same foundation: one customer profile, one segmentation engine, and flows that mix email and text in a single customer journey. An abandoned-cart sequence can send an email, wait, then follow up by text, all from the same workflow builder. The Shopify integration is deep, and the free tier lets small stores start on both channels without paying.
The honest framing is that Klaviyo is email-first. SMS gets full automation and segmentation, but the platform's center of gravity is email, and some SMS specialists offer deeper texting-specific features like conversational commerce or advanced list-growth tools. Pricing also deserves attention: it scales with contacts and message volume, so a growing list means a growing bill. For stores that want one platform for both channels and already run email on Klaviyo, adding SMS there is usually the right call.
website: https://attentive.com/ best_for: Mid-market and enterprise brands running high-revenue SMS programs starting_price: See website free_plan: See website pros: AI-driven personalization, strong deliverability and compliance tooling, hands-on strategic support cons: Custom enterprise pricing, overkill for small stores
Attentive helped define SMS marketing for ecommerce, and its platform now spans SMS, email, RCS and push with AI woven through personalization, send-time optimization and copy generation. The pitch is performance at scale: identity resolution that recognizes customers across channels, deliverability engineering that holds up during peak events like Black Friday, and compliance tooling that keeps high-volume programs inside carrier rules across 20+ countries. Customer stories on the homepage claim dramatic journey revenue multiples.
This is an enterprise sale with custom pricing, and the platform assumes a team that can run a serious messaging program. Small stores will find the commercial model and the feature depth more than they need; Omnisend or SlickText will serve them better for less. But brands doing meaningful SMS revenue, especially those that absorbed Yotpo's SMS customer base after its 2025 shutdown, will find Attentive one of the most capable options available.
website: https://postscript.io/ best_for: Shopify brands that want SMS as a primary revenue channel starting_price: See website free_plan: See website pros: SMS-first platform rebuilt for AI-era retention, strong Shopify focus, transparent sending rates cons: Shopify-centric, less attractive if email is your main channel
Postscript rebuilt its platform from the ground up for what it calls agentic retention marketing: SMS, RCS and email unified, with an AI context layer that personalizes at the individual subscriber level. The homepage emphasizes lower sending rates with no hidden fees and no profile fees, a direct jab at competitors whose invoices surprise customers. Conversational commerce is the differentiator: two-way texting where shoppers can ask questions, get recommendations and complete purchases inside the message thread.
The specialization is also the limitation. Postscript is built for Shopify and for brands where SMS carries real revenue weight; WooCommerce or BigCommerce stores, and brands where email dominates, get less of the benefit. Pricing is usage-based, which keeps small programs affordable and lets large ones scale. If your store runs on Shopify and you believe SMS should be a top-three revenue channel, Postscript deserves a serious evaluation.
website: https://omnisend.com/ best_for: Small and mid-size stores wanting email plus SMS without enterprise pricing starting_price: See website free_plan: Yes (free plan) pros: Email, SMS and push in one platform, aggressive pricing against Klaviyo, free 5-day migration cons: Less depth than enterprise specialists, advanced features trail Attentive
Omnisend positions itself directly against Klaviyo on value: the homepage claims invoices up to 35% smaller for comparable power, with a free 5-day migration service to lower the switching barrier. The platform covers email, SMS and push with automation workflows for welcome series, abandoned carts and post-purchase follow-ups, plus AI-assisted copy, send-time optimization and segmentation. For a growing store that finds Klaviyo's pricing uncomfortable, Omnisend is the first alternative to price out.
The trade-off is ceiling rather than floor. Enterprise-grade personalization, global compliance depth and the strategic support Attentive provides are not really Omnisend's game. But most stores never need that game. If your program is welcome flows, cart recovery, campaigns and post-purchase messages across email and SMS, Omnisend delivers the core at a friendlier price, and the free plan makes the comparison cheap to run.
website: https://slicktext.com/ best_for: Businesses that want straightforward SMS marketing with clear pricing starting_price: See website free_plan: Free trial pros: Every feature on every plan, excellent list-growth tools, strong support reputation cons: Shallower ecommerce automation than suite platforms, MMS costs extra
SlickText keeps things simple on purpose: every plan includes every feature, so pricing is about message volume rather than gated capabilities. The list-growth toolkit is the standout: popups, keywords, tap-to-join links, QR codes and web forms that feed subscribers into automated workflows built with a drag-and-drop builder. Integrations cover Shopify, HubSpot, Salesforce and the usual marketing stack, and the support team has a genuinely strong reputation in reviews.
What you do not get is the deep ecommerce automation of Klaviyo or the conversational commerce of Postscript. SlickText is a texting platform that connects to your store, not a commerce marketing suite. For stores that want SMS as a solid secondary channel, or for businesses where texting serves marketing plus operations like appointment reminders, that simplicity is a feature. Pricing starts low and scales with volume, with a free trial to test.
website: https://simpletexting.com/ best_for: Small businesses that want an easy texting platform with human support starting_price: See website free_plan: Free trial pros: Very easy to use, two-way texting inbox, free trial with no credit card cons: Less ecommerce-specific than Klaviyo or Omnisend, automation less deep
SimpleTexting has spent over a decade making business texting approachable, and the homepage shows it: import contacts or grow a list with popups and keywords, send blasts, hold two-way conversations in a team inbox, and set up automations without touching code. The free trial lets you text your own number with no credit card, which is the fastest way to feel how the platform works. Compliance is handled with care, which matters in a channel where carrier rules bite.
The platform is a general texting tool rather than an ecommerce specialist. Shopify integration exists, but the abandoned-cart flows, product feeds and revenue attribution of the commerce suites are thinner here. That makes SimpleTexting a better fit for stores where SMS supports the business, announcements, promotions, customer service, than for stores trying to maximize SMS-attributed revenue. Ease of use and support quality are the reasons to choose it.
website: https://recart.com best_for: Shopify brands focused on list growth and welcome revenue starting_price: See website free_plan: See website pros: OneClick popups purpose-built for Shopify, DTC flow templates, free account build-out cons: Shopify-only, narrower scope than full marketing suites
Recart does one thing and does it well: growing SMS lists for Shopify stores and converting those subscribers. Its OneClick popups let shoppers join with a single tap instead of typing a phone number, and the platform ships DTC flow templates for welcome series, abandoned cart, browse abandonment and replenishment. Account build-out, including a full SMS audit, is done for you free, which lowers the activation energy for teams new to the channel.
The scope is deliberately narrow. Recart is not an email platform and not a general texting tool; it is a Shopify SMS growth and automation product. Stores on other platforms cannot use it, and brands wanting email plus SMS in one place should look at Klaviyo or Omnisend. But if your store is on Shopify and your SMS program lives or dies on list growth, Recart's specialized toolkit is worth comparing against the broader suites.
website: https://eztexting.com best_for: Easy mass texting and MMS campaigns for small businesses starting_price: See website free_plan: Free trial pros: Simple to use, MMS with image editing, text-to-pay and multilingual texting cons: Less ecommerce automation depth, smaller integration ecosystem
EZ Texting pitches itself as SMS marketing that is easy to use and impossible to outgrow. The platform covers bulk SMS, MMS with a built-in image editor, two-way texting, automated workflows and opt-in tools, plus less common features like text-to-pay payment links and multilingual messaging. Compliance defaults are preloaded, so first-time users stay inside carrier rules without studying them. A free trial gets you sending quickly.
For ecommerce specifically, EZ Texting is a generalist. It lacks the deep store integrations, product-triggered flows and revenue attribution of the commerce-focused platforms, so it fits stores where SMS is a broadcast and service channel rather than a precision revenue instrument. Small retailers, local businesses and multi-location brands that want simple, reliable texting without a learning curve will find it comfortable.
Start with your platform and your ambition. On Shopify with serious SMS revenue goals, compare Postscript and Attentive, with Klaviyo as the all-in-one alternative. On WooCommerce, BigCommerce or Wix, Klaviyo and Omnisend integrate most naturally. If SMS is a secondary channel and simplicity matters more than depth, SlickText, SimpleTexting or EZ Texting will cost less and ask less of your team.
Then model the full cost before you commit. Get the platform fee, the per-message or per-credit rate, the carrier pass-through fees, and the cost of any add-ons like dedicated numbers or MMS, then multiply by your realistic monthly volume. Ask each vendor what a 50,000-message month actually invoices, because the pricing page rarely tells the whole story. And confirm compliance handling: consent capture, opt-outs, quiet hours and registration are not optional, and the platform should carry most of that burden.
Finally, trial with a real segment, not a demo list. Import a slice of your actual subscribers, build one welcome flow and one abandoned-cart flow, and measure revenue per recipient against your current email program. SMS should earn its higher per-message cost with higher conversion; the trial is where you prove it does.
We defined the category as platforms that send marketing SMS for ecommerce stores, from full marketing suites to dedicated texting tools. Candidates came from ecommerce publications, practitioner discussion and vendor homepages, which we opened and verified directly. We excluded Yotpo, which shut down its SMS and email products at the end of 2025, and replaced it with an active competitor.
We weighted ecommerce integration depth, automation quality, list-growth tools, pricing transparency and fit for different store sizes. That is why the list mixes all-in-one suites with SMS specialists and simple texting tools: a seven-figure Shopify brand and a local boutique need different things. Every website URL in this guide was verified by opening the vendor's homepage.
It is sending promotional and transactional text messages to shoppers who opted in: cart reminders, back-in-stock alerts, flash sales, order updates and win-back offers. SMS typically earns higher open and conversion rates than email, but each message costs more to send, so targeting matters.
Costs combine a platform fee, a per-message rate, and carrier pass-through fees. Small programs can start around tens of dollars monthly on tools like SlickText or SimpleTexting; large programs on Attentive or Klaviyo scale into thousands. Always model your real monthly volume, not the headline rate.
Yes, with consent. In the US, the TCPA requires express written consent before marketing texts, plus clear opt-out handling; carriers enforce 10DLC registration. Reputable platforms build consent capture, opt-outs and quiet hours into the product, but the legal responsibility stays with the sender.
Not necessarily. Klaviyo's built-in SMS covers automation, segmentation and campaigns well for most stores. Consider a specialist like Postscript or Attentive when SMS becomes a primary revenue channel and you want deeper conversational features, list growth or deliverability engineering.
RCS (Rich Communication Services) is the richer successor to SMS, supporting branded messages, images and interactive buttons in the native messaging app. Attentive and Postscript already support it. It is worth watching, but SMS reach is universal today while RCS coverage is still growing.
