SMS Marketing | Text Message Marketing
SMS marketing has a 98% open rate and most messages are read within three minutes. Clearwell builds and manages SMS marketing programs that reach your customers where they actually are — on their phones — with the right message at the right moment.
SMS Marketing – Text Message Marketing
Email sits in an inbox. Social media competes with everything else in the feed. A text message goes directly to your customer's phone and gets read within three minutes in the overwhelming majority of cases. SMS marketing is the most direct customer communication channel available — and most businesses are barely using it.

The Highest Open Rate Channel in Marketing Is the One Most Businesses Aren't Using
Email open rates average somewhere between 20 and 35 percent depending on your industry and list quality. Social media organic reach has been declining for years. Paid advertising requires ongoing spend to maintain any visibility. Meanwhile the average SMS marketing message has a 98 percent open rate and most of those opens happen within three minutes of the message being sent.
That gap is not a small one. It is the difference between a message that most of your audience never sees and a message that almost all of them read almost immediately.
Most businesses are not using SMS marketing for one of three reasons. They are worried about being intrusive. They do not have a compliant list building system in place. Or they have SMS capability through their email platform and have never properly built it out because it felt complicated.
All three of those barriers are easily solved. The intrusion concern disappears when your messages are genuinely relevant and sent at appropriate frequency — customers who opted in to hear from you and receive messages worth reading do not feel intruded upon. The compliance requirements are straightforward when you have the right systems in place. And the technical complexity of building SMS into an existing marketing stack is manageable when you know what you are doing.
The businesses getting serious results from SMS are not doing anything complicated. They are sending the right messages to the right people at the right frequency — and they are reaching an audience that is actually paying attention.
What Clearwell's SMS Marketing Services Include
Every SMS marketing engagement starts with an honest assessment of your current situation — what platform you are on, what list you have, what compliance gaps exist, and what the highest-revenue SMS opportunities are for your specific business before any campaigns are built.
SMS Strategy and Program Design
Building the complete SMS marketing strategy before anything is built or sent — defining your objectives, identifying the right use cases for SMS in your specific business, designing the message frequency and cadence that serves your customers without fatiguing them, establishing the segmentation architecture that ensures every message is relevant to the recipient, and creating the program framework that guides every subsequent SMS decision. SMS without strategy produces high opt-out rates. SMS with strategy produces revenue.
Compliant List Building and Opt-In Setup
The foundation of any effective SMS program is a list of genuinely opted-in subscribers — built through a compliant process that meets TCPA, CTIA, and platform-specific requirements. We design and implement the opt-in flows that build your SMS list correctly from the start — website pop-ups, checkout opt-ins, keyword opt-in campaigns, lead magnet delivery sequences, and any other list building mechanism appropriate for your business. Compliance is not optional and it is not an afterthought — it is built into every component of the program from day one.
Automated SMS Flow Development
The automated message sequences triggered by subscriber behavior and lifecycle stage — the SMS equivalents of your email automation flows, built to leverage the immediacy and intimacy of the SMS channel for the moments where that immediacy produces the highest impact. Abandoned cart SMS sequences. Post-purchase delivery updates and review requests. Welcome sequences for new subscribers. Re-engagement campaigns for lapsed customers. Win-back sequences for customers who have not purchased in a defined period. Every flow is designed around your specific customer journey and the specific moments where an SMS message produces meaningfully better results than an email.
Campaign Strategy and Management
The ongoing promotional and informational SMS campaigns that run alongside your automation flows — flash sale announcements, new product launches, time-sensitive offers, event reminders, and the regular engagement messages that maintain top-of-mind presence without overloading your subscribers. We develop the campaign calendar, write the copy, segment the audience, and manage the send schedule so your SMS campaigns go out consistently and strategically rather than reactively and sporadically.
E-Commerce SMS Marketing
For Shopify and WooCommerce stores SMS marketing is one of the highest-ROI channels available — particularly for abandoned cart recovery where the immediacy of SMS produces significantly higher recovery rates than email alone. We build the complete eCommerce SMS program — abandoned cart sequences, back-in-stock notifications, shipping updates, post-purchase sequences, and the promotional campaign calendar that drives consistent SMS revenue alongside your email program.
Service Business SMS Marketing
For service businesses SMS marketing serves a different set of objectives — appointment reminders that dramatically reduce no-show rates, follow-up sequences after service completion, review requests sent at the optimal moment, referral programs communicated through the highest-attention channel available, and the re-engagement campaigns that bring lapsed clients back into active relationships. We build SMS programs specifically designed around the service business customer lifecycle.
Platform Setup and Integration
Setting up your SMS marketing platform correctly — whether that is Klaviyo SMS for eCommerce businesses already on the platform, Attentive for high-volume eCommerce programs, Postscript for Shopify-focused SMS, or another platform appropriate for your specific situation. Every platform setup covers compliance configuration, sending number setup, opt-in flow implementation, platform integration with your CRM or eCommerce store, and the foundational configuration that ensures deliverability and compliance from the first message sent.
Analytics and Performance Reporting
Monthly reporting on your SMS program performance — subscriber list growth, opt-out rates, open rates, click rates, revenue attributed to SMS campaigns and flows, and the cost-per-message economics that determine whether the program is generating proportional return. We track SMS performance alongside your email performance to understand how the two channels complement each other and where the right balance of investment lies between them.
SMS and Email Aren't Competitors – They're a Team
The most common mistake in SMS marketing strategy is treating SMS as a replacement for email or as a direct duplicate of it. It is neither. SMS and email are different channels with different strengths, different appropriate use cases, and different relationships with the recipients who have opted into both.
Understanding where each channel performs best and designing your marketing program so each channel plays the role it is best suited for is what produces a genuinely high-performing communication strategy rather than one channel cannibalizing the other.
Email is best for:
Content that requires context and length, such as educational content, detailed product announcements, newsletters, and the kind of nurture communication that builds a relationship over time through substance rather than immediacy. Email is patient. Recipients open it when they are ready, engage with it at their own pace, and expect a certain richness of content that justifies the inbox real estate.
Email is also better for content that benefits from visual presentation — product photography, branded design templates, image-heavy promotional content. SMS is a text channel and doesn't accommodate images natively in the way email does.
SMS is best for:
Time-sensitive communication where immediacy matters. Flash sales with a genuine deadline. Abandoned cart recovery where reaching the customer in minutes rather than hours meaningfully affects recovery rate. Appointment reminders where the timing of the reminder relative to the appointment determines whether it is useful. Shipping and delivery updates where real-time information has practical value. Back-in-stock notifications for high-demand products where the customer wants to know immediately.
SMS is also better for communication that needs to feel personal. A well-written SMS message from a brand you trust reads like a message from a person. A badly written one – especially one using a promotional style – reads like spam and produces immediate opt-outs.
The coordinated approach:
The most effective programs use SMS and email in complementary sequences — email carrying the relationship-building and content-rich load, SMS handling the time-sensitive and high-urgency touchpoints. An abandoned cart sequence might start with an SMS within 30 minutes of abandonment followed by an email sequence that provides more context and social proof. A new product launch might be announced via email with full photography and description followed by an SMS reminder for subscribers who opened but did not purchase. Each channel does what it does best and the two together produce better results than either does independently.
SMS Compliance – What You Need to Know Before Sending a Single Message
SMS marketing is a federally regulated activity in the United States. The Telephone Consumer Protection Act (TCPA) establishes strict requirements for how businesses can communicate with consumers via text message, and violations are costly. This is not a compliance concern to be understood vaguely and hoped for the best about, but rather a legal requirement that needs to be built correctly into every component of your SMS program from the start.
The compliance requirements are not complicated when you understand them — but they are non-negotiable and the consequences of getting them wrong are significant.
Explicit opt-in is required.
You cannot send marketing text messages to someone who has not explicitly opted in to receive them from your business. This means purchasing phone number lists, importing contacts from your CRM without a clear opt-in record, or adding phone numbers collected for other purposes to your SMS list are all non-compliant practices that create legal liability and deliverability issues.
The opt-in must be properly documented.
The opt-in process must clearly disclose that the subscriber is agreeing to receive marketing messages from your business, the approximate frequency of messages, and how to opt out. This disclosure needs to be present at the point of opt-in — not buried in terms and conditions.
Opt-out must be immediate and honored.
Any subscriber who texts STOP must be immediately removed from all future marketing messages. This is non-negotiable. Platforms handle this automatically when configured correctly but it needs to be verified as part of every program setup.
Sending hours matter.
TCPA restricts marketing messages to the hours of 8am to 9pm in the recipient's local time zone. Sending outside these hours is a violation regardless of whether the content is otherwise compliant.
Every message needs proper identification.
Every marketing SMS message must clearly identify who is sending it. Ambiguous sender identification that does not make the brand identity clear is a compliance risk.
Clearwell builds every SMS program with compliance as a foundational requirement — not a box checked at the end. Every opt-in flow, every automation, and every campaign is designed to meet TCPA requirements before it is designed to maximize revenue.
Choosing the Right SMS Platform for Your Business
Not every SMS platform is right for every business. The right platform depends on your business model, your existing marketing technology stack, your list size, and your specific use cases. Here is how the major platforms compare and when each makes sense:
Klaviyo SMS
For eCommerce businesses already using Klaviyo for email the SMS add-on is the most natural choice. The integration between email and SMS is seamless — the same segmentation logic, the same behavioral triggers, and the same campaign management interface cover both channels. The cross-channel coordination that Klaviyo enables — SMS and email working together within the same flow architecture — is the strongest available for eCommerce. For Shopify stores already on Klaviyo this is almost always the right answer.
Attentive
The enterprise SMS platform for high-volume eCommerce brands. Attentive has the most sophisticated list growth tools available — their two-tap mobile opt-in technology consistently produces higher opt-in rates than standard keyword opt-in methods. For stores generating significant SMS revenue and wanting the most capable dedicated SMS platform it is the strongest option. Higher cost than Klaviyo SMS but more purpose-built for SMS-first programs.
Postscript
Built specifically for Shopify SMS marketing with deep native Shopify integration. Strong list growth tools, clean Shopify data integration, and a focus on eCommerce use cases. A good option for Shopify stores that want a dedicated SMS platform rather than Klaviyo's integrated approach.
SimpleTexting and EZTexting
More appropriate for service businesses and local businesses with smaller lists and simpler use cases — appointment reminders, local event promotion, customer follow-up. Lower cost, simpler functionality, and appropriate for programs that do not require the behavioral trigger sophistication of eCommerce-focused platforms.
GoHighLevel SMS
For businesses already on the GoHighLevel CRM platform the native SMS capability handles most service business SMS needs — appointment reminders, follow-up sequences, and review request automations — without requiring a separate platform subscription.
SMS Marketing Is Right for Your Business If...
- You have a customer and subscriber list with phone numbers you aren't currently using for SMS marketing
- You're an e-commerce business that wants to add abandoned cart SMS recovery and promotional campaigns to your existing email program
- You're a service business that wants to reduce no-shows through appointment reminder sequences and increase reviews through post-service SMS requests
- You're already on Klaviyo and want to build out the SMS capability you're paying for but aren't currently using
- You want to reach your most engaged customers through the highest-attention channel available rather than competing for inbox attention with every other email they receive
- You want to add a high-ROI marketing channel that complements rather than duplicates your existing email program
- You've tried SMS marketing before without a real strategy behind it and want to build a program that is both compliant and genuinely effective
Why Choose Clearwell for Your SMS Marketing
SMS marketing combines legal compliance requirements, technical platform configuration, copywriting skill, and strategic sequencing in a way that most marketing agencies handle superficially — setting up the basic platform configuration and sending promotional blasts without the compliance rigor, the strategic framework, or the copy quality that makes an SMS program genuinely valuable rather than just annoying.
Clearwell treats SMS as a strategic channel within your broader marketing program — not a standalone tactic bolted onto your existing marketing without integration. Every SMS sequence is designed in the context of your email flows, your CRM data, your customer lifecycle stage, and the specific moments where the immediacy of SMS produces meaningfully better results than other channels.
We manage every SMS engagement with direct understanding of the compliance requirements, the platform capabilities, and the strategic frameworks that produce effective SMS programs. Every program is built on a compliance foundation but for marketing performance.
We also approach SMS with honest restraint — recommending message frequency and content standards that serve your subscriber relationships rather than maximizing short-term engagement at the cost of opt-out rates and long-term list health. An SMS program that burns through your list with over-sending is not a marketing asset. One that delivers genuine value at the right frequency is one of the most direct customer relationships available in modern marketing.
Frequently Asked Questions - SMS Marketing Services
Yes — SMS marketing is legal when done correctly and a violation of federal law when done incorrectly. The Telephone Consumer Protection Act — TCPA — requires explicit opt-in from every subscriber before you can send them marketing messages, proper disclosure at the point of opt-in, immediate opt-out processing when subscribers reply STOP, sending only during permitted hours of 8am to 9pm in the recipient's local time zone, and clear brand identification in every message. Penalties for violations run from $500 to $1,500 per message. Clearwell builds every SMS program with compliance as the foundation — the legal requirements are not optional and they are not complicated when the program is set up correctly from the start.
SMS reaches a phone directly and gets read within minutes in the overwhelming majority of cases — producing dramatically higher open rates than email. Email is better suited for content-rich, longer-form communication that benefits from visual presentation and does not require immediate attention. SMS is better for time-sensitive communication where immediacy matters — abandoned cart recovery, appointment reminders, flash sales with genuine deadlines, shipping updates, and back-in-stock notifications. The most effective marketing programs use both channels in complementary roles rather than choosing one over the other.
Through explicit opt-in only. Website pop-ups that clearly disclose the SMS program and ask for phone number alongside email. Checkout opt-in on eCommerce stores with proper disclosure. Keyword opt-in campaigns where customers text a word to a number to subscribe. Paper forms at point of sale with SMS opt-in clearly disclosed. In-store QR codes linking to a compliant opt-in form. Every opt-in mechanism needs to clearly state what the subscriber is agreeing to receive, the approximate frequency, and how to opt out. Clearwell designs and implements compliant opt-in flows as a standard component of every SMS program setup.
Message frequency depends on your business type, your offer cadence, and your subscriber expectations. For most eCommerce businesses two to four marketing SMS messages per month — separate from automated transactional messages — is a reasonable starting point. Service businesses typically send less frequently — primarily transactional messages around appointments and service completion with occasional promotional sends. The right frequency is the highest frequency at which your opt-out rate stays healthy and your engagement metrics remain strong. We establish specific frequency guidelines for every program based on your specific situation.
Only if you have documented opt-in from those customers specifically for SMS marketing. Phone numbers collected for other purposes — voice calls, account verification, service scheduling — do not constitute SMS marketing opt-in under TCPA requirements. Starting with non-opted-in phone numbers creates significant legal liability regardless of the existing customer relationship. The right approach is to build a compliant opt-in list from the start — and we can help design the opt-in campaigns that build that list from your existing customer base through proper consent mechanisms.
SMS marketing program investment at Clearwell is scoped based on the platform being used, the complexity of your automation requirements, the scope of your campaign management needs, and whether SMS is being built as a standalone program or integrated alongside your email marketing engagement. SMS messaging costs also vary by platform and message volume. We scope every engagement individually after understanding your specific situation.
