How Restaurants Capture Guest Data with WiFi Marketing

The Anonymous Diner Problem

Most restaurants serve hundreds of customers every week and capture zero contact details from the vast majority. Walk-ins, bar guests, event attendees, and even many reservation guests leave without providing an email address. This means you cannot:

• Send them a follow-up email with a promotion or event invitation
• Ask them for a Google review (the single most impactful local SEO action)
• Know how often they visit or what they typically spend
• Target them with personalised offers based on their behaviour

Guest WiFi marketing solves this. By requiring a simple email login to access your restaurant WiFi, you capture guest data from every connected visitor - automatically, with zero staff effort.

How WiFi Data Capture Works

The process is simple:

1. Guest connects to WiFi: They select your restaurant WiFi network on their phone.
2. Branded splash page appears: Instead of connecting directly, they see your branded login page with your logo, colours, and a friendly welcome message.
3. Guest enters their email: They provide their email address (and optionally name and phone number) and tick a GDPR consent checkbox.
4. Internet access granted: They get online. The whole process takes 10-15 seconds.
5. Data flows to your dashboard: Their email, name, visit time, and consent status appear in your CaptiFi dashboard in real time.

What Data You Capture

With CaptiFi, every WiFi login captures:

• Email address - the core asset for all follow-up marketing
• Name (optional) - enables personalised emails
• Phone number (optional) - enables SMS marketing via Twilio
• Marketing consent - GDPR-compliant opt-in recorded with timestamp
• Visit timestamp - when they connected, enabling visit frequency analysis
• New vs returning - CaptiFi automatically identifies repeat visitors
• Device type - iOS, Android, laptop

Linking WiFi Data with Toast POS

CaptiFi integrates with Toast POS to create a complete customer profile. When a WiFi guest also places an order through Toast, CaptiFi links the two records. This gives you:

• Spend-based segmentation: Identify high-spenders, medium-spenders, and low-spenders
• Menu preferences: See what WiFi guests typically order
• VIP targeting: Send exclusive offers to your top 10% of customers by spend
• Lapsed customer recovery: Identify high-spenders who haven't visited in 30+ days and send them a comeback offer

Automating Google Reviews

After a guest connects to WiFi, CaptiFi can automatically send a Google review request. The timing is optimised for maximum conversion - typically 4 hours after the visit, when the guest has left and is reflecting on their experience.

This passive, automated approach typically generates 8-15 new Google reviews per week for a busy restaurant - without any staff needing to ask customers directly. Over 6 months, this can transform a restaurant from 50 Google reviews to 200+, significantly improving local search ranking.

Email Marketing from WiFi Data

With a growing email list from WiFi captures, restaurants can run targeted campaigns:

• Welcome sequence: Automated emails to first-time visitors with a thank-you and a next-visit discount
• Weekly specials: Promote your weekly menu, events, or live music
• Birthday offers: If you capture birth dates, send automated birthday discounts
• Lapsed customer re-engagement: Target guests who haven't visited in 30+ days
• Seasonal campaigns: Christmas menus, Valentine's Day, Mother's Day - targeted to your actual customer base

CaptiFi includes built-in email marketing, or you can sync with Mailchimp for more advanced campaigns.
