WiFi Email Capture

WiFi email capture is the process of collecting guest email addresses through a captive portal when they connect to a venue's guest WiFi network. The guest enters their email to get online, and the venue builds a marketing list automatically.

How WiFi Email Capture Works

The venue's WiFi network is configured with a captive portal. When a guest connects, they see a branded splash page instead of going straight to the internet. The splash page asks for their email address. Once they submit it, they get WiFi access. Their email is stored in a database the venue controls.

The process takes a few seconds from the guest's perspective and requires no staff involvement. There are no clipboards, no app downloads, and no manual data entry. The list grows every day the venue is open.

What Makes It Different From Other Email Collection Methods

Traditional email collection in hospitality relies on asking guests to fill in a form, drop a business card in a bowl, or sign up on a tablet at the till. These methods depend on staff remembering to ask, and most guests decline.

WiFi email capture removes the friction. The guest is already connecting to WiFi. They expect to enter an email (hotels, airports, and coffee shops have normalised this). The conversion rate is significantly higher than manual methods. At The Shamrock Social in Nottingham, 40% of guests opted in to marketing through WiFi capture in the first month.

GDPR Compliance

In the UK, WiFi email capture must comply with GDPR. The key principle is that marketing consent must be separate from WiFi access. The guest enters their email to connect (legitimate interest for providing the service), and a separate, unticked checkbox lets them opt in to marketing. Only guests who tick the box go on the marketing list. For more detail, see our pub WiFi guide.

What Venues Use WiFi Email Capture For

Venues use the captured email list to send promotions for quiet nights, promote events and seasonal menus, bring back lapsed customers with "we miss you" offers, and reduce OTA dependency for hotels by reaching past guests directly for rebookings. The list is also used for understanding footfall patterns: new vs returning guests, visit frequency, and peak days.
