Welcome to the Purple Technical Briefing. Today, we're discussing a critical but often overlooked asset in your technology stack: Guest WiFi Marketing. For many, guest WiFi is a cost centre—an amenity you’re expected to provide. But what if you could transform it into a powerful engine for lead capture, sales, and unparalleled customer insight? That’s our focus today.

(Intro Music Fades)

Over the next ten minutes, we’ll cover the technical architecture for turning your WiFi into a marketing tool, provide a practical implementation guide, and discuss the ROI you can expect. This is for the IT managers, network architects, and venue directors who need to deliver measurable business value.

Let's begin with the technical deep-dive. The magic of guest WiFi marketing happens at the intersection of your network hardware and a specialised software platform. The core components are your Access Points (APs), a controller or gateway that manages them, and the marketing platform itself, like Purple, which sits on top.

The most critical element from a user-facing perspective is the **Captive Portal**. This is the login page users see before they get online. It’s your digital front door. Instead of a simple password field, a marketing-enabled portal offers several authentication methods. First, the simple form-fill, capturing a name and email address—this is your bread and butter for building mailing lists. Second, social login, using credentials from platforms like Facebook, Google, or LinkedIn. This is far richer, providing access to verified demographic data, interests, and more—all with user consent, of course. Finally, you might use a voucher or access code system, common in hotels or for tiered access.

So, how does the data flow? When a guest authenticates, their data—be it an email or social profile information—is passed from the captive portal to the WiFi marketing platform. This is where the real intelligence lies. The platform validates the data, de-duplicates it, and, most importantly, links it to the user's device MAC address. This allows you to track their behaviour in the venue: how often they visit, how long they stay, and even where they move within the space, using WiFi signal strength to generate location analytics and heatmaps.

From there, the data must be integrated into your wider marketing stack. This is typically done via direct API integrations or webhooks. For example, a new email capture can trigger a webhook that instantly adds the contact to your HubSpot or Salesforce CRM and enrols them in a welcome journey on Mailchimp. This seamless integration is what separates a basic setup from an enterprise-grade marketing machine.

Underpinning all of this are critical standards. For security, you should be deploying WPA3 where possible, and using network segmentation to isolate guest traffic from your corporate network. And for data handling, compliance with GDPR and CCPA is non-negotiable. Your platform must provide robust consent management tools, clear privacy policies, and mechanisms for honouring data subject rights, like the right to be forgotten.

Now, let's move to implementation. How do you get this right? First, start with clear business goals. Don't just collect data for its own sake. Do you want to increase loyalty program sign-ups by 15%? Or drive a 10% uplift in repeat visits? Your goals will dictate your strategy.

Second, create a clear value exchange. Customers are savvy; they won't give you their data for nothing. The offer on your captive portal must be compelling. This could be a simple 10% discount on their next purchase, a free coffee, or access to a high-speed premium network tier. The value must be immediate and obvious.

Third, integrate, integrate, integrate. The real power is unleashed when your WiFi analytics platform talks to your CRM. This allows you to connect offline behaviour with online profiles. Imagine knowing that a customer who just walked into your store is the same person who abandoned their online shopping cart yesterday. You could trigger a real-time offer to their device to close that sale.

However, there are pitfalls. The most common is an overly complex login process. If you ask for ten fields of information, your connection rate will plummet. Keep it simple: first name and email is often enough. Another major pitfall is ignoring compliance. You must get explicit, informed consent for marketing communications. Pre-ticked boxes are not compliant under GDPR. Finally, a classic mistake is poor network performance. If the underlying WiFi is slow and unreliable, any marketing efforts are doomed. Your infrastructure must be robust, with sufficient bandwidth and AP density to handle peak loads.

Time for a rapid-fire Q&A. First question: How much data can we realistically collect? The answer is to be guided by the principle of data minimisation. Collect only what you need for a specific, stated purpose. An email for marketing, perhaps a postcode for regional analysis. Don't ask for a phone number if you have no intention of using it.

Second: What's the biggest security risk? An improperly configured guest network. It must be completely segregated from your internal corporate network. Use VLANs and firewall rules to ensure there is no path for an attacker to cross from the guest environment into your critical systems.

And third: What does the ROI look like? It's highly measurable. You can track the growth of your marketing database, measure the open and click-through rates of WiFi-triggered email campaigns, and attribute in-store sales to specific digital promotions. By linking footfall data from the WiFi analytics to your marketing campaigns, you can finally close the loop between digital spend and physical-world outcomes.

So, to summarise. Guest WiFi is no longer just an IT utility; it's a strategic marketing asset. By implementing a professional-grade platform, you can turn anonymous visitors into known customers, understand their behaviour in your venues, and drive measurable business growth. The key is to focus on a clear value exchange, ensure seamless integration with your existing marketing stack, and maintain a relentless focus on security and data privacy compliance.

Your next step? Audit your current guest WiFi experience. Is it a dead end, or is it the start of a customer relationship? If it's the former, it's time to architect a solution that delivers real, measurable ROI.

कार्यकारी सारांश

गेस्ट WiFi आता केवळ एक सुविधा राहिलेली नाही; ती लक्षणीय व्यावसायिक मूल्य प्रदान करण्यास सक्षम असलेली एक धोरणात्मक संपत्ती आहे. CTOs, IT व्यवस्थापक आणि ठिकाण संचालकांसाठी, गेस्ट WiFi कडे केवळ एक आवश्यक ऑपरेशनल खर्च म्हणून न पाहता एक प्रोअॅक्टिव्ह मार्केटिंग आणि अॅनालिटिक्स इंजिन म्हणून पाहणे आवश्यक आहे. हे मार्गदर्शक ते परिवर्तन साध्य करण्यासाठी तांत्रिक आणि धोरणात्मक फ्रेमवर्क प्रदान करते. मार्केटिंग-सक्षम गेस्ट WiFi सोल्यूशन तैनात करून, संस्था समृद्ध, फर्स्ट-पार्टी ग्राहक डेटा कॅप्चर करू शकतात, भौतिक जागांवर अभ्यागतांचे वर्तन समजू शकतात आणि मोजता येण्याजोगा परतावा (ROI) देणाऱ्या लक्ष्यित मार्केटिंग मोहिमा चालवू शकतात. मुख्य घटकांमध्ये एक मजबूत नेटवर्क इन्फ्रास्ट्रक्चर, डेटा संपादन करण्यासाठी एक अत्याधुनिक Captive Portal आणि CRM व मार्केटिंग ऑटोमेशन प्लॅटफॉर्म्ससह अखंड एकत्रीकरण (integration) समाविष्ट आहे. महत्त्वाचे म्हणजे, हे सुरक्षित आणि अनुपालन (compliant) फ्रेमवर्कमध्ये अंमलात आणले जाणे आवश्यक आहे, ज्यामध्ये नेटवर्क सुरक्षेसाठी WPA3 आणि डेटा गोपनीयतेसाठी GDPR सारख्या मानकांचे पालन केले जाते. याचा परिणाम म्हणजे एक शक्तिशाली साधन जे डिजिटल आणि भौतिक ग्राहक प्रवासातील दरी कमी करते, वैयक्तिकृत अनुभव सक्षम करते आणि महसूल वाढवते.

तांत्रिक सखोल माहिती (Technical Deep-Dive)

गेस्ट WiFi मार्केटिंग सोल्यूशनच्या आर्किटेक्चरमध्ये तीन प्राथमिक स्तर असतात: नेटवर्क इन्फ्रास्ट्रक्चर, Captive Portal आणि मार्केटिंग प्लॅटफॉर्म, आणि इंटिग्रेशन आणि अॅनालिटिक्स स्तर.

नेटवर्क इन्फ्रास्ट्रक्चर: तुमचा विद्यमान WiFi हार्डवेअर—अॅक्सेस पॉइंट्स (APs), कंट्रोलर्स आणि गेटवेज हा याचा पाया आहे. प्रभावी लोकेशन अॅनालिटिक्ससाठी, डिव्हाइसच्या स्थानांचे अचूक त्रिकोणीकरण (triangulate) करण्यासाठी AP ची घनता पुरेशी असणे आवश्यक आहे. नेटवर्क सेगमेंटेशन अत्यंत महत्त्वाचे आहे; VLANs (Virtual LANs) आणि कठोर फायरवॉल नियमांचा वापर करून गेस्ट ट्रॅफिक कॉर्पोरेट नेटवर्कपासून वेगळे केले पाहिजे. यामुळे सार्वजनिक नेटवर्कवरून उद्भवणाऱ्या सुरक्षा उल्लंघनाचा धोका कमी होतो. पोर्ट-आधारित नेटवर्क अॅक्सेस कंट्रोलसाठी IEEE 802.1X आणि मजबूत एन्क्रिप्शनसाठी WPA3 चे पालन करणे ही एंटरप्राइझ-ग्रेड सुरक्षेसाठी मूलभूत आवश्यकता आहे.
Captive Portal आणि मार्केटिंग प्लॅटफॉर्म: हा सॉफ्टवेअर स्तर आहे जो तुमच्या नेटवर्क हार्डवेअरवर बसतो. जेव्हा एखादा वापरकर्ता गेस्ट SSID शी कनेक्ट होतो, तेव्हा त्याला Captive Portal वर पुनर्निर्देशित (redirect) केले जाते. साध्या पासवर्ड एंट्री पेजच्या विपरीत, मार्केटिंग पोर्टल एकाधिक प्रमाणीकरण (authentication) पद्धती ऑफर करते:
- ईमेल/फॉर्म भरणे: लीड कॅप्चर करण्यासाठी सर्वात थेट पद्धत.
- सोशल लॉगिन: (उदा. Google, LinkedIn, Facebook) वापरकर्त्याच्या संमतीने अधिक समृद्ध, प्रमाणित डेमोग्राफिक डेटा प्रदान करते.
- व्हाउचर/अॅक्सेस कोड: टायर्ड अॅक्सेस आणि वेळेपुरते मर्यादित सेशन्स सक्षम करते, जे हॉस्पिटॅलिटी क्षेत्रात सामान्य आहे.

प्लॅटफॉर्म हा डेटा कॅप्चर करतो, तो डिव्हाइसच्या MAC पत्त्याशी लिंक करतो आणि एका केंद्रीकृत डेटाबेसमध्ये संचयित करतो. येथेच स्पष्ट संमती चेकबॉक्सेस आणि गोपनीयता धोरणांच्या स्पष्ट लिंक्सद्वारे GDPR आणि इतर डेटा गोपनीयता नियमांची अंमलबजावणी केली जाते.

इंटिग्रेशन आणि अॅनालिटिक्स स्तर: कॅप्चर केलेल्या डेटाचे खरे मूल्य इंटिग्रेशनद्वारे अनलॉक केले जाते. REST APIs आणि Webhooks वापरून, WiFi मार्केटिंग प्लॅटफॉर्मने बाह्य सिस्टीम्सना रिअल-टाइममध्ये डेटा पुरवला पाहिजे:
- CRM सिस्टीम्स (Salesforce, HubSpot): ठिकाणावरील वर्तनासह ग्राहक प्रोफाइल समृद्ध करण्यासाठी.
- मार्केटिंग ऑटोमेशन (Mailchimp, Klaviyo): स्वयंचलित ईमेल/SMS मोहिमा ट्रिगर करण्यासाठी (उदा. परत येणाऱ्या अभ्यागतासाठी "वेलकम बॅक" ऑफर).
- बिझनेस इंटेलिजन्स (BI) टूल्स: विक्री डेटासह WiFi अॅनालिटिक्सचा सहसंबंध जोडण्यासाठी.

हा स्तर अॅनालिटिक्स डॅशबोर्ड देखील प्रदान करतो, जो फूटफॉल, ड्वेल टाइम्स (थांबण्याची वेळ), अभ्यागतांची निष्ठा आणि लोकेशन हीटमॅप्सबद्दल इनसाइट्स देतो.

अंमलबजावणी मार्गदर्शक

गेस्ट WiFi मार्केटिंग सोल्यूशन तैनात करण्यासाठी टप्प्याटप्प्याने दृष्टिकोन आवश्यक आहे:

व्यावसायिक उद्दिष्टे परिभाषित करा: प्राथमिक उद्दिष्टे काय आहेत? मेलिंग लिस्टचा आकार 25% ने वाढवणे? रिपीट बिझनेसमध्ये 10% वाढ करणे? 5% इन-स्टोअर विक्रीला WiFi-आधारित प्रमोशनशी लिंक करणे? स्पष्ट KPIs आवश्यक आहेत.
इन्फ्रास्ट्रक्चर ऑडिट: तुमच्या सध्याच्या नेटवर्कचे मूल्यांकन करा. लोकेशन अॅनालिटिक्ससाठी AP कव्हरेज पुरेसे आहे का? तुमचा गेटवे थर्ड-पार्टी Captive Portal प्लॅटफॉर्म्ससह इंटिग्रेशनला सपोर्ट करतो का? यासाठी अनेकदा सखोल साइट सर्वेक्षणाची आवश्यकता असते.
प्लॅटफॉर्मची निवड: तुमच्या उद्दिष्टांची पूर्तता करणारा प्लॅटफॉर्म निवडा. मुख्य बाबींमध्ये CRM इंटिग्रेशन्सची व्याप्ती, त्याच्या अॅनालिटिक्सची प्रगत पातळी आणि त्याच्या अनुपालन टूल्सची मजबुती यांचा समावेश होतो. व्हेंडर-न्यूट्रल विहंगावलोकनासाठी खालील तुलना चार्ट पहा.
ग्राहक प्रवासाची रचना करा: कनेक्शनपासून ते भेट दिल्यानंतरच्या संवादापर्यंत वापरकर्त्याच्या अनुभवाचा आराखडा तयार करा. स्पष्ट मूल्य विनिमयासह (उदा. "तुमचा ईमेल आणि 15% डिस्काउंट व्हाउचरच्या बदल्यात मोफत WiFi") एक स्वच्छ, मोबाइल-फर्स्ट Captive Portal डिझाइन करा.
कॉन्फिगर आणि इंटिग्रेट करा: Captive Portal कॉन्फिगर करा, मार्केटिंग ऑटोमेशन ट्रिगर्स सेट करा आणि तुमच्या CRM शी API लिंक्स स्थापित करा. हे एक तांत्रिक काम आहे ज्यासाठी नेटवर्क आणि मार्केटिंग टीम्समध्ये सहकार्य आवश्यक आहे.
पायलट आणि इटरेट करा: मर्यादित संख्येत ठिकाणी लाँच करा. कनेक्शन दर, डेटा कॅप्चर गुणवत्ता आणि मोहिमेच्या कामगिरीचे निरीक्षण करा. पूर्ण रोलआउट करण्यापूर्वी दृष्टिकोन सुधारण्यासाठी इनसाइट्सचा वापर करा.

सर्वोत्तम पद्धती

वापरकर्ता अनुभवाला प्राधान्य द्या: संथ, गुंतागुंतीची किंवा अविश्वसनीय लॉगिन प्रक्रिया दत्तक घेण्यास (adoption) मारक ठरेल. फॉर्म्स लहान ठेवा आणि कनेक्शन प्रक्रिया अखंड ठेवा.
स्पष्ट मूल्य विनिमय ऑफर करा: वापरकर्त्यांना बदल्यात मूर्त मूल्य मिळाल्यास ते डेटा शेअर करण्यास अधिक तयार असतात. हे प्रीमियम स्पीड, डिस्काउंट किंवा विशेष आशय असू शकते.
डिझाइनमध्ये अनुपालन एम्बेड करा: डेटा गोपनीयता ही नंतर विचार करण्याची गोष्ट नाही. Captive Portal वरील संमतीपासून ते CRM मधील डेटा व्यवस्थापनापर्यंतची प्रत्येक पायरी GDPR/CCPA अनुपालक असल्याची खात्री करा.
सेगमेंट आणि वैयक्तिकृत करा: प्रत्येक वापरकर्त्याला समान संदेश पाठवू नका. तुमच्या प्रेक्षकांचे विभाजन करण्यासाठी डेटा वापरा (उदा. पहिल्यांदा येणारे विरुद्ध पुन्हा येणारे अभ्यागत) आणि संवाद वैयक्तिकृत करा.
नेटवर्क सुरक्षित करा: तुमच्या नेटवर्क सेगमेंटेशन आणि फायरवॉल नियमांचे नियमितपणे ऑडिट करा. गेस्ट नेटवर्क्स हे एक सामान्य अटॅक व्हेक्टर आहेत.

ट्रबलशूटिंग आणि जोखीम निवारण

कमी कनेक्शन दर: अनेकदा खराब वापरकर्ता अनुभवामुळे होते. लॉगिन प्रक्रिया सोपी करा, नेटवर्क कार्यप्रदर्शन सुधारा किंवा WiFi सेवेची दृश्यमानता वाढवा.
खराब डेटा गुणवत्ता: बनावट किंवा चुकीच्या नोंदी कमी करण्यासाठी तुमच्या Captive Portal वर रिअल-टाइम ईमेल प्रमाणीकरण लागू करा. उच्च-गुणवत्तेच्या, सत्यापित डेटासाठी सोशल लॉगिनला प्राधान्य द्या.
अनुपालन उल्लंघन: सर्वात मोठी जोखीम. तुमचा संपूर्ण डेटा प्रवाह अनुपालक असल्याची खात्री करण्यासाठी कायदेशीर टीम्ससोबत काम करा. संमती आणि डेटा विषयक विनंत्या व्यवस्थापित करण्यासाठी अंगभूत, स्वयंचलित अनुपालन टूल्स असलेल्या प्लॅटफॉर्मचा वापर करा.
नकारात्मक ROI: हे तेव्हा घडते जेव्हा डेटा गोळा केला जातो परंतु त्यावर कारवाई केली जात नाही. इंटिग्रेशन स्तर कार्य करत असल्याची आणि मार्केटिंग टीम्स लक्ष्यित मोहिमा चालवण्यासाठी डेटाचा सक्रियपणे वापर करत असल्याची खात्री करा.

ROI आणि व्यावसायिक प्रभाव

गेस्ट WiFi मार्केटिंगचा ROI अनेक अक्षांवर मोजला जातो:

मार्केटिंग डेटाबेस वाढ: WiFi प्लॅटफॉर्मद्वारे मिळवलेल्या निव्वळ नवीन संपर्कांचा मागोवा घ्या. उद्योग बेंचमार्क्सच्या आधारे प्रत्येक लीडला मूल्य नियुक्त करा.
वाढलेली विक्री: WiFi-चालित प्रमोशन्सना महसूल श्रेय द्या. उदाहरणार्थ, Captive Portal वर ऑफर केलेल्या डिस्काउंट कोड्सच्या रिडेम्प्शन दराचा मागोवा घ्या.
सुधारित ग्राहक निष्ठा: सिस्टीम लागू झाल्यानंतर ज्ञात ग्राहकांच्या वारंवार भेटींमधील वाढ मोजा.
ऑपरेशनल कार्यक्षमता: कर्मचाऱ्यांची पातळी, स्टोअर लेआउट्स आणि उघडण्याच्या वेळा ऑप्टिमाइझ करण्यासाठी फूटफॉल आणि ड्वेल टाइम डेटा वापरा.

ऑफलाइन वर्तनाला डिजिटल प्रोफाइल्सशी जोडून, गेस्ट WiFi मार्केटिंग ओम्नीचॅनेल ग्राहक प्रवासातील गहाळ दुवा प्रदान करते, ज्यामुळे नफ्यावर (bottom line) स्पष्ट आणि मोजता येण्याजोगा प्रभाव पडतो.

Key Terms & Definitions

Captive Portal

A web page that the user of a public-access network is obliged to view and interact with before access is granted. In a marketing context, it's the primary tool for data capture.

IT teams deploy captive portals as the gateway to the guest network. It's the bridge between the network infrastructure and the marketing platform.

MAC Address (Media Access Control)

A unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment.

The WiFi marketing platform links a user's captured data (e.g., email) to their device's MAC address to track their presence and behaviour (dwell time, repeat visits) anonymously.

VLAN (Virtual Local Area Network)

A logical grouping of devices in the same broadcast domain. VLANs are usually configured on switches by placing some interfaces into one broadcast domain and some into another.

This is the fundamental mechanism IT teams use to segregate the guest WiFi network from the secure internal corporate network, preventing lateral movement by attackers.

GDPR (General Data Protection Regulation)

A regulation in EU law on data protection and privacy in the European Union and the European Economic Area.

For any organisation collecting data from EU citizens, GDPR compliance is mandatory. IT and marketing teams must ensure the WiFi platform provides tools for explicit consent, data access requests, and the right to be forgotten.

Webhook

An automated message sent from an app when something happens. It has a message—or payload—and is sent to a unique URL—a webhook URL.

This is how a WiFi platform can instantly notify a CRM when a new guest connects. For example, a webhook can trigger an action in Salesforce to create a new lead record the moment a guest logs into the WiFi.

Presence Analytics

The analysis of data from WiFi signals to understand how many people are in a physical space, without identifying them personally.

Venue operators use this data to understand footfall patterns, peak hours, and popular areas, allowing them to optimise staffing, layout, and operations.

Location Analytics

A more granular form of analytics that uses the signal strength from multiple access points to triangulate a device's position within a venue.

This provides heatmaps and path analysis, showing where visitors spend the most time and the routes they take. It requires a higher density of APs than simple presence analytics.

WPA3 (Wi-Fi Protected Access 3)

The latest generation of security for wireless networks. It provides more robust authentication and increased cryptographic strength.

Network architects should specify WPA3-compatible hardware for all new deployments to provide the highest level of security for guest and corporate wireless networks.

Case Studies

A 200-room luxury hotel wants to increase direct bookings and build a guest database for marketing, moving away from reliance on Online Travel Agencies (OTAs). They have a modern Cisco Meraki network infrastructure.

The hotel integrates Purple with their Meraki dashboard. They configure a captive portal offering two tiers of WiFi: a free, standard-speed service requiring email and consent for marketing, and a paid, high-speed premium service. The captured email is sent via webhook to their HubSpot CRM and added to a 'New Guest' workflow. This workflow sends a welcome email with a 10% discount code for their next direct booking. The hotel also uses the presence analytics to understand guest flow in the lobby, bar, and spa, helping them optimise staffing.

Implementation Notes: This is a strong solution because it combines a clear value exchange (free WiFi for data), tiered access to create an upsell opportunity, and direct integration into a marketing automation platform to immediately act on the captured data. Using an existing Meraki infrastructure simplifies deployment, as no new hardware is required.

A retail chain with 50 stores wants to understand in-store customer behaviour and drive footfall through targeted promotions. They use a mix of Aruba and Ruckus hardware.

The chain deploys a hardware-agnostic platform like Purple across all 50 stores. They use a social login (Facebook/Google) on their captive portal to gather rich demographic data. This data is fed into their central BI tool. They identify that their highest-value customers (those with high repeat visits and long dwell times) are predominantly in the 25-34 age bracket. They then run a targeted Facebook ad campaign aimed at this demographic in the geographic areas around their underperforming stores, promoting a new product line. The WiFi analytics are then used to measure the uplift in footfall from this specific demographic post-campaign.

Implementation Notes: This solution demonstrates the power of closing the loop between online advertising and offline behaviour. The hardware-agnostic nature of the platform is key for a mixed-estate deployment. The use of social login provides richer data for ad targeting, and the WiFi analytics serve as the measurement tool to prove the campaign's ROI.

Scenario Analysis

Q1. A large conference centre is hosting a 3-day tech event with 5,000 attendees. They want to provide WiFi while also giving event sponsors opportunities for lead generation. How would you architect the WiFi solution?

💡 Hint:Consider tiered access and how to provide value to both attendees and sponsors.

Show Recommended Approach

Implement a two-tiered WiFi system. Tier 1 is a free, baseline-speed service for all attendees, with a captive portal that requires only email registration. This builds the centre's own marketing list. Tier 2 is a sponsored, high-speed premium service. Attendees can access it by opting-in to share their details (name, email, company) with a specific sponsor. Each major sponsor gets their own 'branded' access portal. This provides high-quality leads for sponsors and a clear value exchange for attendees (premium speed for data). The network must be robust with high AP density in breakout rooms and the main hall to handle the load.

Q2. A public library wants to offer free WiFi but is concerned about GDPR compliance and data security. They have a limited budget and minimal IT staff. What is the most critical first step in their deployment?

💡 Hint:What is the single most important security measure for any guest network?

Show Recommended Approach

The most critical first step is to ensure complete network segmentation. Using a VLAN, the guest WiFi network must be entirely isolated from the library's internal administrative network. This prevents any possibility of a user on the public network accessing sensitive internal systems, like the library management system or staff computers. Before even considering data capture, this fundamental security measure must be implemented and verified. A simple, reliable firewall rule blocking all traffic between the guest VLAN and the internal VLAN is essential.

Q3. A restaurant chain notices a high connection rate on their guest WiFi but a very low open rate on their marketing emails. What is the likely cause and how would you troubleshoot it?

💡 Hint:Think about the quality of the data being captured at the source.

Show Recommended Approach

The most likely cause is poor data quality, specifically fake or mistyped email addresses being entered on the captive portal. To troubleshoot, first analyse the captured data for obvious fake domains (e.g., test@test.com). The best long-term solution is to implement real-time email validation via an API on the captive portal. This checks if an email address is valid before the user is granted access. An alternative or complementary solution is to incentivise social logins, which provide verified email addresses and richer data, leading to higher engagement.
