To capture emails from guest WiFi, you need a captive portal - a branded login page that requires guests to enter their email before accessing the internet.

Captive portal software like CaptiFi sits between your WiFi access points and the internet. When a guest connects, they see your branded splash page and must provide their email (or log in via social media) to get online. The email is captured automatically, marketing consent is recorded for GDPR compliance, and you can trigger follow-up emails, Google review requests, and marketing campaigns - all without any manual work.

CaptiFi is a guest WiFi marketing platform for venues, restaurants, hotels, cafés, retail spaces and short-term rentals. It turns branded WiFi logins into first-party customer data, automated Google review requests, repeat visitor insights and email marketing lists.

6 Steps to Capture Emails from Guest WiFi

1

Choose a Captive Portal Platform

Select a WiFi marketing platform that supports your access points and includes email capture, marketing automation, and review requests. CaptiFi works with UniFi, TP-Link Omada, Cisco Meraki, Aruba, MikroTik, Ruckus, Cambium, and DrayTek - and includes a free starter device if you need one.

2

Set Up Your Branded Splash Page

Create a branded WiFi login page with your logo, colours, and messaging. The page should ask guests for their email address (and optionally name and phone number) before granting internet access. CaptiFi includes a drag-and-drop splash page builder with professional templates.

3

Configure Your Access Points

Point your WiFi access points to the external captive portal URL provided by your platform. On UniFi, go to Settings → WiFi → Guest Portal and enter your CaptiFi portal URL. On TP-Link Omada, use the External Portal feature. Setup takes under 10 minutes on any hardware.

4

Enable GDPR-Compliant Consent Capture

Add marketing consent checkboxes to your splash page. This is required by GDPR in the UK/EU and is best practice everywhere. CaptiFi handles consent capture, creates an audit trail for every guest, and applies automatic data retention policies.

5

Set Up Automated Follow-Ups

Configure welcome emails, Google review requests, and follow-up marketing campaigns to trigger automatically after a guest connects. CaptiFi includes built-in email marketing, Mailchimp sync, Twilio SMS, and automated review requests - no extra tools needed.

6

Monitor and Optimise

Use your analytics dashboard to track email capture rates, repeat visits, review generation, and campaign performance. CaptiFi provides real-time analytics with AI-powered insights to help you optimise your splash page design and follow-up timing.
