WiFi email capture is the technique of collecting a guest's email address as a condition of free WiFi access, typically through a captive portal's sign-in form, so the venue can send marketing communications afterwards.
WiFi email capture is the most common — and lowest-friction — form of guest data capture. The splash page asks for an email address (and optionally name + marketing opt-in), the device gets connected, and from that moment forward the venue can include the guest in welcome flows, review-request automations, win-back campaigns, and segmented promotions.
An email-only captive portal typically captures 60-80% of unique devices that load the splash page; offering social login alongside (Facebook, Google) lifts that to 80-95%. Guests are far more willing to enter an email here than on a website pop-up because they\'re actively trying to get something (free WiFi) in return.
Real-time email validation in the captive portal (catching typos, disposable-email domains, and obvious mis-fires) keeps bounce rates below 3% — essential for sender reputation and to stay out of spam folders. Without validation, expect 8-15% bounce on collected lists, which damages deliverability quickly.
Industry-specific examples: how a San Francisco Airbnb host generated $14,300/month in commission-free revenue; welcome email sequence templates.
A captive portal is a web page that public WiFi users see before being granted internet access — typically used to authenticate users, accept terms, and capture data such as email or social-login identity.

Guest WiFi is a public, internet-only WiFi network a business offers to customers, separate from its private back-office network, typically secured by a captive portal that requires sign-in.
Capture guest emails, run automated email/SMS campaigns, and grow Google reviews — all from your existing WiFi.
