SMS Marketing Agency for Compliant, Profitable Text Programs

An SMS marketing agency has a narrower margin for error than an email team. Text messages are read quickly, cost money per message, and carry strict consent rules. Send too often or without clear permission and subscribers leave, carriers filter your messages, or you face legal risk. Send well and SMS becomes one of the most direct channels you own.

We run SMS as part of our email marketing and automation services, because the two channels work best when planned together. Our focus is Shopify and WooCommerce brands selling in the US, and we also set up programs for Canada, the UK and Australia, where the consent rules differ.

What Is SMS Marketing?

SMS marketing is sending promotional and service text messages to customers who have explicitly opted in to receive them from your brand. For ecommerce, that means automated texts triggered by behavior (a welcome after sign-up, a reminder after an abandoned checkout, a shipping update) plus campaign texts for launches, restocks and time-limited offers. MMS is the same channel with an image or GIF attached, at a higher cost per message.

What separates it from email is immediacy and cost. Texts are short, read on the phone within minutes, and billed per message segment, so every send has a visible price. That is why a good program texts fewer people, less often, with more reason to act.

SMS marketing software is the platform that stores subscribers and their consent records, sends messages through registered numbers, runs automated flows and reports revenue per message. For ecommerce brands, Klaviyo SMS, Postscript and Attentive are the usual options, and the choice mostly depends on which email platform you already use.

SMS Marketing Services We Provide

• Platform setup. Klaviyo SMS, Postscript, Attentive or Omnisend, connected to your store with the right sending number type for your volume and markets.
• Consent and compliance setup. Opt-in language, keyword replies, quiet hours, frequency rules and number registration, handled before the first send.
• List growth. Mobile sign-up forms that collect email first and phone second, two-tap mobile opt-in where the platform supports it, checkout consent collection, and keyword or QR code opt-ins for packaging, events and stores.
• Automated text flows. Welcome, abandoned checkout, browse abandonment, shipping updates, post-purchase and winback texts.
• Campaigns. Launches, restocks, early access and time-limited offers sent to engaged segments, coordinated with the email calendar.
• Reporting. Revenue, cost, click rate and unsubscribe rate for every message, so you can see the return on each send.

How We Launch an SMS Program

1. Choose the SMS marketing provider and number (week 1). If you already use Klaviyo, its SMS feature usually keeps data and reporting in one place. A dedicated automated texting service such as Postscript or Attentive makes sense for brands with heavy text volume or specific features. We compare costs per message and required registrations before recommending either.
2. Register and configure (week 1, approval time varies). US business texting now requires carrier registration: toll-free verification for toll-free numbers, or 10DLC brand and campaign registration for standard long codes. We prepare the submission, which needs your business details and sample messages.
3. Build opt-in collection (weeks 1 to 2). Forms, checkout consent and keyword opt-ins go live with the required disclosure text. We make sure consent status syncs correctly to your platform, so nobody receives a marketing text without permission.
4. Launch flows first (weeks 2 to 3). Welcome and abandoned checkout texts go live before any campaign, because they reach people at the moment they are most interested.
5. Add campaigns and tune frequency (from week 4). We start with a modest cadence, watch unsubscribe rates and revenue per message, and adjust. The target is revenue per send, not message volume.

Platform setup and flows usually take two to three weeks. Carrier registration can add time because approval depends on carrier review queues, so we submit it on day one and build forms and flows in parallel.

How to Increase Sales With SMS Marketing Without Burning the List

To increase sales with SMS marketing, text fewer people with better reasons: automate the moments of high intent, segment campaigns by behavior, and make every message easy to act on from a phone. The tactics we use most:

• Automate high-intent moments first. Abandoned checkout, browse abandonment for engaged subscribers, back-in-stock and price-drop alerts reach people who already want the product.
• Segment campaigns. Recent clickers and repeat buyers get launch and early-access texts; the wider list gets fewer, stronger offers.
• Link straight to the product or cart. Every extra tap on a phone loses buyers, so links open the exact product, collection or restored cart.
• Use two-way replies. Subscribers often reply with questions about sizing or shipping. Routing those replies to your support inbox turns a campaign into a sales conversation.
• Exclude recent buyers. Someone who ordered yesterday should not get today's discount text.
• Send by local time zone. A morning launch text should arrive in the morning on both coasts, not at dawn in California.

SMS Marketing Mistakes That Cost Subscribers and Deliverability

• Texting the whole list several times a week with the same generic discount.
• Leaving the brand name out of the message, which carriers and subscribers both expect to see.
• Using public link shorteners, which carriers often filter. Platform-branded or your own domain links are safer.
• Collecting phone numbers at checkout for delivery updates, then sending marketing texts without separate marketing consent.
• Long messages full of emoji that are billed as several segments and read like spam.
• Sending the same message by email and text within minutes, so the second one only annoys.

SMS Marketing Services Deliverables and What Success Looks Like

• A compliance file with your opt-in disclosures, keyword responses, quiet hours, registration status and consent sources documented in one place.
• A flow map showing each text flow, its timing, how it is staggered against the matching email, and the exit rules.
• A campaign calendar combined with the email calendar, so both channels are planned together.
• A monthly report with revenue, message cost, revenue per message, click rate, opt-out rate and list growth by source.

Success means text revenue that clearly exceeds message cost, opt-out rates that stay steady as the list grows, and email and SMS revenue rising together rather than one channel taking credit from the other. We do not promise a set return per message; it depends on your products, prices and how engaged your subscribers are.

SMS Marketing Checklist: Compliance Before the First Send

In the US, marketing texts fall under the Telephone Consumer Protection Act (TCPA), which requires prior express written consent for automated marketing messages. Several states have their own stricter rules on consent, timing and frequency. We are not your lawyers, and we recommend your counsel reviews your consent language, but we build every program to the standard practices carriers and platforms expect:

• Clear opt-in disclosure stating the brand, that messages are recurring and automated, that consent is not a condition of purchase, and how to opt out.
• STOP, HELP and similar keywords working on every number, with opt-outs honored immediately.
• Quiet hours in the recipient's local time zone, set in the platform so campaigns cannot go out late at night.
• Separate consent records for SMS and email, since one does not imply the other.
• Market-specific rules outside the US: PECR in the UK, CASL in Canada and the Spam Act in Australia each set their own consent and identification requirements.

Email and SMS: Which Message Goes Where

Message length affects cost. A standard SMS segment holds 160 characters, but a single emoji or special character switches the encoding and cuts a segment to 70 characters, so a long text with emoji can be billed as several messages. We write to the segment limit and use MMS images only where they earn the extra cost.

SMS Marketing Use Cases by Store Type

• Fashion and apparel: drop alerts, low-stock warnings on popular sizes and early access for repeat buyers.
• Beauty and consumables: replenishment reminders timed to product size, and subscription renewal or skip prompts.
• Food and beverage: limited releases, delivery-day updates and local pickup reminders.
• High-ticket goods: fewer campaign texts, more service texts such as delivery scheduling and answers to pre-purchase questions by reply.

Who Should Hire an SMS Marketing Company

A good fit: ecommerce brands with an engaged email list and regular launches, restocks or promotions; brands with a mobile-heavy customer base; and stores already on Klaviyo that want to add text marketing services without hiring a separate SMS marketing agency.

Probably not a fit: B2B companies whose buyers do not want sales texts, businesses without a clear consent process, and brands that plan to text the whole list several times a week. If your email flows are not yet in place, start with our Klaviyo agency service, then add SMS.

Our abandoned cart email guide shows how email and text reminders can share the work of recovering a checkout, which is usually the first place SMS proves its value.

SMS Marketing Pricing

Our SMS marketing agency work is managed under our email and retention retainers, sized by the number of flows and campaigns across both channels, with a three-month minimum term. Message costs are billed by your SMS platform directly to you, so you always see what each send costs. Our fee depends on the number of text flows and campaigns, whether SMS is added to an existing email retainer or run alongside a new one, the number of markets with different consent rules, and how much MMS creative is needed.

Not sure SMS fits your store yet? Send us your list size and platform for a custom quote and an honest view on whether text is worth adding.
