Email gets a 20% open rate. SMS gets 98% — and most texts are read within 3 minutes of receipt. Lumo builds compliant SMS marketing programs that drive immediate revenue: promotional campaigns, automated flows, cart abandonment recovery, and loyalty programs for US businesses.
Every other marketing channel competes for attention. Social media algorithms decide whether your post gets shown. Email providers filter messages to promotions folders or spam. Search ads require the prospect to actively search. SMS bypasses every one of these gatekeepers — your message arrives directly in the most personal communication channel your customer has, and they almost always read it.
The engagement gap is staggering. Email achieves 20% open rates on a good day. SMS achieves 98%, with 90% of messages read within 3 minutes. Click-through rates follow suit — SMS CTR averages 19% versus email's 2.5%. For time-sensitive offers, abandoned carts, appointment reminders, and flash promotions, there is no channel that reaches customers faster or more reliably.
Lumo builds SMS programs that are both high-performing and fully TCPA-compliant. Every program starts with consent architecture — ensuring opt-ins are explicit, documented, and legally defensible — before any messages are sent. We manage list health, carrier compliance, and message content to protect your brand and your customer relationships.
Promotional text campaigns for sales, launches, and limited offers — with audience segmentation, send-time optimisation, A/B testing, and post-campaign performance analysis.
Behaviour-triggered SMS sequences — welcome series, post-purchase flows, re-engagement campaigns, and milestone messages — that run automatically based on customer actions and lifecycle stage.
Cart abandonment SMS sequences that recover lost e-commerce revenue — timed message series with personalised product references, social proof, and offer triggers to bring shoppers back to checkout.
Opt-in keyword setup, consent collection workflows, TCPA compliance architecture, subscriber segmentation, and list hygiene management — the legal and technical foundation of a healthy SMS program.
VIP subscriber list management, exclusive SMS-first offers, birthday and anniversary triggers, and loyalty reward programs that increase customer lifetime value and repeat purchase rates.
Delivery rate, open rate, click rate, conversion, and revenue-per-message tracking — with monthly reports and optimisation recommendations across campaigns, flows, and list segmentation.
Configure SMS platform (Klaviyo, Attentive, or Postscript), set up opt-in keywords, build consent collection, configure carrier settings, and establish TCPA-compliant list management procedures.
Write campaign messaging, design automated flow sequences, set up segmentation logic, configure send-time windows, and establish frequency rules — balancing revenue performance with subscriber experience.
Deploy flows and first campaigns, monitor delivery rates and carrier filtering, track opt-out rates as a health signal, and adjust messaging and timing based on early performance data.
A/B test message copy and CTAs, expand flow coverage, grow subscriber list through pop-up and checkout opt-in optimisation, and scale campaign frequency as subscriber engagement data matures.
Yes, when implemented correctly. SMS marketing in the US is regulated by the Telephone Consumer Protection Act (TCPA), which requires explicit written consent before sending marketing texts. Lumo builds every SMS program with TCPA compliance as the foundation — proper opt-in consent collection, clear disclosures, easy opt-out mechanisms (STOP keyword), and documented consent records. Non-compliant SMS can result in significant fines, so we treat compliance as non-negotiable.
Lumo works with Klaviyo, Attentive, Postscript, SMSBump, and Omnisend — selecting the platform based on your e-commerce setup, existing tech stack, and subscriber volume. For non-e-commerce businesses, we also work with Twilio and SimpleTexting for service-based SMS programs.
List building for SMS uses multiple collection points: website pop-ups with SMS opt-in, checkout opt-in for e-commerce, keyword opt-ins ('Text JOIN to 12345'), social media promotions driving keyword sign-ups, and integrated opt-in on email sign-up forms. Lumo designs a multi-channel list growth strategy alongside the SMS program itself to ensure subscriber volume grows consistently.
Frequency depends on your subscriber base and content quality. For e-commerce, 4–8 promotional SMS per month is the standard range — supplemented by automated flows triggered by behaviour. For service businesses, 2–4 per month is typical. The signal to watch is opt-out rate: above 2% per campaign suggests either too-high frequency or irrelevant messaging.
SMS and email are complementary, not competing. Email is better for longer content, storytelling, and content marketing. SMS is better for time-sensitive offers, urgency, and immediate engagement. The best programs use both — email for nurturing and relationship-building, SMS for promotions that need to be seen and acted on immediately. Lumo coordinates both channels to avoid message fatigue and overlap.
