## How to Collect Customer Emails in Your Pub

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.

## Why Email Beats Social Media for Pub Marketing

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.

[![Discover Purple Engage](https://hubspot-no-cache-eu1-prod.s3.amazonaws.com/cta/default/25553249/6dc3fbbb-c7b6-4cb4-b6bf-f6f62cd047fa.png)](https://hubspot-cta-redirect-eu1-prod.s3.amazonaws.com/cta/redirect/25553249/6dc3fbbb-c7b6-4cb4-b6bf-f6f62cd047fa)

 

## Understanding What You Get at Each Level

[**Purple Connect — Free**](http://join.purple.ai)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](https://join.purple.ai). Customers get a great experience. You get a professional setup. Customer data capture is not included at this tier.

[**Purple Engage — Paid**](https://join.purple.ai/purple-engage-smb) This is where email collection begins. Every customer who connects through your branded portal can opt in to hear from you. [Purple Engage](https://join.purple.ai/purple-engage-smb) 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%.

## How the Login Process Works

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:

- **Social media login:** One tap with Facebook or Google — verified name and email captured instantly
- **Simple form:** Name and email address only — keep it to two fields or you will lose sign-ups
- **One-click access:** They agree to your terms and connect immediately — device data and consent recorded

 

**[Start free with Purple Connect](https://join.purple.ai)**

 

## The GDPR Rules You Must Follow

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.

 

## What to Do With the Emails Once You Have Them

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.

## Common Mistakes to Avoid

**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](https://join.purple.ai) is a compact plug-and-play device (15cm × 10cm) that has your guest network live in under an hour.
