Collecting customer emails in a pub means capturing GDPR-compliant contact details through a branded guest WiFi login portal, then using those contacts to run automated marketing campaigns that bring people back. Purple Connect is a free guest WiFi platform used by over 80,000 venues worldwide that gives any UK pub a professional branded portal from day one. Purple Engage — Purple's paid marketing tier — turns those logins into a verified customer database and automated email campaigns that drive repeat visits.
If you ask most pub landlords how many of their customers they could contact tomorrow with a special offer, the honest answer is: almost none. A handful of Facebook followers, maybe an old email list nobody has touched in two years.
That is a serious missed opportunity. Your pub is already busy. People are through the door every week. The problem is not footfall — it is that those customers walk out and you have no direct way to invite them back.
Here is exactly how guest WiFi changes that.
Social media algorithms decide who sees your posts. Email lands directly in someone's inbox. For a pub running a midweek offer or a birthday promotion, that direct line is worth far more than a boosted Facebook post — and it reaches people who have already been in and enjoyed themselves.
The key is building a list of people who actually want to hear from you. That is where guest WiFi becomes your most powerful tool. But it is worth being clear upfront: capturing customer emails requires a paid tier. Here is how the tiers work.
Purple Connect — Free This is your starting point. A professional branded splash page with your pub's logo and colours, secure guest network isolation (your tills and business systems kept completely separate from customer devices), and a fast reliable WiFi experience for up to 250 simultaneous users across a 200m range via the Purple Hub. Customers get a great experience. You get a professional setup. Customer data capture is not included at this tier.
Purple Engage — Paid This is where email collection begins. Every customer who connects through your branded portal can opt in to hear from you. Purple Engage builds a clean, verified contact database automatically — no spreadsheets, no manual entry. Every contact is verified and spam-checked before entering your list. Purple Engage venues see an average marketing opt-in rate of 35%.
Whether you are on Connect or Engage, customers see a branded login page when they connect. With Engage active, that login becomes a data capture point:

The moment you collect an email address through your WiFi, you become a data controller under GDPR. Three non-negotiable requirements:
Explicit consent: You must use a separate, unticked checkbox for marketing opt-in. Never pre-tick it.
Clear privacy information: Your login page must link to a privacy policy explaining what data you collect and how you use it.
Provable records: You need a documented consent record for every contact. Purple Engage generates this automatically at every login.
With Purple Engage, your contact list feeds directly into automated marketing campaigns:
| Trigger | Automated Email | Result |
|---|---|---|
| First visit | "Thanks for coming in — here's 10% off your next visit" | Incentivises a swift return |
| Birthday approaching | "Enjoy a free drink on us this week" | Personal touch that drives a celebratory visit |
| Not seen for 30 days | "We miss you — come back for something special" | Re-engages lapsed customers before they go elsewhere |
| Post-visit | "How was your visit? Leave us a review" | Routes happy customers to Google or TripAdvisor |
These are not generic blasts. They are triggered by actual customer behaviour. Purple Engage venues see an average 24% customer return rate and an 8% increase in spend through tailored campaigns.
Expecting data capture on the free plan: Connect gives you excellent guest WiFi. To collect emails, you need Engage. Be clear on what each tier delivers before you start.
Asking for too much at login: Name and email is enough. Every extra field costs you opt-ins.
Not promoting the WiFi: Table cards, menu mentions, staff reminders. If customers do not know it exists, they will not connect.
Using a basic home router: A home broadband setup cannot run a branded login page, isolate your network properly, or feed a marketing platform.
The Purple Hub is a compact plug-and-play device (15cm × 10cm) that has your guest network live in under an hour.
