How to leverage SMS for marketing examples to increase return visits

PODCAST SCRIPT: How to use SMS for marketing examples to increase return visits Duration: approximately 10 minutes Voice: UK English, senior consultant tone - confident, conversational, authoritative --- INTRODUCTION AND CONTEXT - approximately 1 minute Welcome back. I'm speaking with you today as a senior consultant at Purple, and we're going to talk about something that a lot of venue operators are sitting on without realising it - a direct line to their guests, shoppers, and fans that delivers a 98% open rate and up to 41 pounds return for every pound spent. That channel is SMS. And before you say "we already do email" - hear me out. Because the numbers between SMS and email are not even close. Email sits at around a 20 to 30% open rate. SMS? 98%. And 90% of those messages are read within three minutes of delivery. The question isn't whether SMS works. The data is settled on that. The question is: how do venue operators - hotels, retail chains, stadiums, conference centres - actually build a compliant, scalable SMS programme that drives measurable return visits? That's what we're covering today. --- TECHNICAL DEEP-DIVE - approximately 5 minutes Let's start with the data problem. Most SMS marketing programmes fail not because of the channel, but because of the data behind them. You cannot run effective SMS campaigns without verified, consented phone numbers. And the best place to capture those at scale, in a venue context, is at the WiFi login. Here's how it works. When a guest, shopper, or fan connects to your Guest WiFi, they authenticate through a captive portal. That portal collects their phone number as part of the login flow. Critically, it also captures explicit consent - a conscious-choice opt-in - for SMS marketing communications. This is the foundation of a GDPR-compliant SMS programme. Purple Engage does exactly this. It captures verified phone data at the point of WiFi login across 80,000 plus live venues, and it automates the campaign workflows that follow. The phone number is verified because the guest has to receive a one-time passcode to complete the login. That means no fake numbers, no typos, no dead ends. Now, once you have that verified, consented first-party data, you can segment it. And segmentation is where SMS marketing gets genuinely interesting for venue operators. Think about a 200-room hotel. Every guest who connects to your WiFi is now in your database. You can segment by: first-time visitor versus returning guest, length of stay, day of week, whether they visited the spa or the restaurant. Each of those segments gets a different message, at a different time, with a different offer. A first-time guest gets a welcome message with a 10% discount on their next booking, sent 48 hours after checkout. A returning guest who has stayed three or more times gets an early access offer for a loyalty rate. A guest who visited the restaurant gets a message about a new seasonal menu. This is not spray-and-pray marketing. This is behavioural segmentation built on first-party data you already own. Let me give you a retail example. A fashion retailer with 50 stores across the UK captures phone numbers at WiFi login in every location. They segment shoppers by store location, visit frequency, and recency. A shopper who visited a Manchester store two weeks ago and hasn't been back gets an SMS: "You left something behind - 20% off this weekend only." That message goes out on a Thursday afternoon, timed for peak weekend shopping intent. The result? A 22% redemption rate on that offer, compared to a 3% redemption rate on the equivalent email campaign. Same offer, same audience, different channel. Now let's talk about the technical architecture. There are three layers to a well-built SMS marketing programme. Layer one is data capture. This is your WiFi infrastructure - Cisco Meraki, HPE Aruba, Ruckus, Juniper Mist, Ubiquiti UniFi - connected to a cloud overlay platform like Purple. The captive portal handles authentication and consent capture. The data flows into a centralised guest profile. Layer two is the data platform. This is where segmentation happens. You need a platform that can ingest WiFi login data, cross-reference it with visit history, and apply behavioural rules to build dynamic audience segments. Purple's analytics platform does this natively, and it integrates with CRM systems like Salesforce and HubSpot via standard API connections. Layer three is the SMS delivery layer. This is your SMS gateway - providers like Twilio, MessageBird, or Vonage - connected to your campaign automation rules. When a segment condition is met, the campaign fires automatically. No manual intervention required. The compliance architecture matters here. Under GDPR and PECR in the UK, you need explicit consent for SMS marketing. That consent must be granular - separate from general terms and conditions - and it must be recorded with a timestamp and source. Purple's captive portal handles all of this, and the consent records are stored and auditable. --- IMPLEMENTATION RECOMMENDATIONS AND PITFALLS - approximately 2 minutes Right. Let's talk about what goes wrong, because I see the same mistakes repeatedly. Pitfall one: treating SMS like email. SMS is not a long-form channel. Your message needs to be under 160 characters, have a single clear call to action, and include an opt-out instruction. "Reply STOP to unsubscribe" is not optional - it's a legal requirement under PECR. If you're writing SMS copy that reads like an email newsletter, you've already lost. Pitfall two: sending too frequently. The research is clear - 53% of SMS unsubscribes happen because of over-frequency. For most venue operators, one to two messages per month per segment is the right cadence. More than that, and you're eroding the list you worked hard to build. Pitfall three: not testing send times. SMS is an immediate channel - 90% of messages are read within three minutes. That means timing matters enormously. A hotel sending a restaurant offer at 9am on a Tuesday will see dramatically lower conversion than the same message sent at 5pm on a Friday. Test your send windows. The data will tell you when your audience is receptive. Pitfall four: skipping the attribution layer. If you can't track which SMS campaign drove which return visit, you can't optimise and you can't justify the budget. Use unique short links, UTM parameters, or redemption codes in every message. Purple's analytics platform tracks campaign attribution natively, so you can see the direct line between an SMS send and a venue visit. My implementation recommendation: start with one segment and one campaign type. Don't try to build the full programme in week one. Pick your highest-value segment - returning guests who haven't visited in 30 days, for example - and build a single re-engagement campaign. Measure it. Optimise it. Then scale. --- RAPID-FIRE Q AND A - approximately 1 minute Let me run through the questions I get most often. "Do we need a separate SMS platform?" Not necessarily. If you're using Purple Engage, SMS campaign automation is built in. You only need a separate SMS gateway integration if you're sending at very high volume or need carrier-specific routing. "What's a realistic return visit uplift from SMS?" Based on Purple's data across hospitality and retail venues, a well-segmented re-engagement SMS campaign typically drives a 15 to 25% increase in return visit rate within 90 days of launch. "How do we handle international guests?" You need to ensure your SMS gateway supports international number formatting and that your consent capture is compliant with the relevant jurisdiction - GDPR for Europe, CCPA for California, and so on. Purple's platform handles multi-jurisdiction consent natively. "What's the minimum viable list size?" You can run effective campaigns with as few as 500 verified, consented contacts. The key is segmentation quality, not list size. --- SUMMARY AND NEXT STEPS - approximately 1 minute Let me bring this together. SMS delivers a 98% open rate, a 45% response rate, and up to 41 pounds ROI per pound spent. Those numbers are not achievable without verified, consented first-party data - and the best place to capture that data at venue scale is at the WiFi login. The architecture is three layers: data capture at the WiFi portal, behavioural segmentation in the data platform, and automated campaign delivery via SMS gateway. Purple Engage handles all three layers natively, with built-in GDPR and PECR compliance. Start with one segment. Build one campaign. Measure the return visit uplift. Then scale. If you want to see how this works in practice, visit purple.ai and look at the Engage plan. You can also explore our WiFi Analytics platform to understand what guest data you're already sitting on. Thanks for listening. We'll be back next time with more practical guidance for venue operators and IT teams who want to get more from their Guest WiFi infrastructure. --- END OF SCRIPT
