Email marketing for bars and pubs
This guide shows owner-operators and marketing managers at bars and pubs how to build a regulars list from guest WiFi logins and use it to fill quiet nights with targeted email. It covers how Purple Engage captures GDPR-compliant first-party data at the captive portal, which automated campaigns deliver the best return on a quiet Tuesday, and how to measure success in footfall and revenue rather than open rates.
Why this matters for your venue
The hardest night to fill is not Saturday. It is Tuesday. You have the crowd at the weekend, but converting that energy into mid-week footfall is where most bars and pubs leave money on the table. Social media organic reach is effectively zero for most venues. Paid ads are expensive and hard to attribute. Asking staff to collect email addresses at the bar never works.
The answer is already mounted on your wall. Your guest WiFi access point captures a verified email address every time a guest connects. That is not a scraped list or a bought database - it is a conscious-choice opt-in, collected in line with GDPR, at the exact moment your guest decides they want to be in your venue. Purple Engage turns those logins into a regulars list that builds itself, then automates the campaigns that bring those guests back.
Venues that do not do this are handing that list to Mailchimp's blank import screen and wondering why nothing grows. Generic email tools send campaigns. They do not build the list. That is the difference.
The approach
Purple Engage uses your existing guest WiFi infrastructure - Cisco Meraki, HPE Aruba, Ruckus, Juniper Mist, Ubiquiti UniFi, and others - as a data capture layer. It sits on top of your hardware as a cloud overlay. You do not replace anything.
When a guest connects, they see a captive portal - the branded login page before they reach the internet. That portal asks for their email address, optionally their date of birth, and presents a clear, unticked marketing consent checkbox. This is a conscious-choice opt-in. It is not buried in terms and conditions. The guest makes an active decision. Purple records the consent timestamp and the specific wording they agreed to, which satisfies the GDPR accountability requirement.
From that point, every return visit is logged against their profile. Purple Engage knows when they first visited, how often they return, how long they typically stay, and when they last came in. That behavioural data is the engine behind every campaign.
The key distinction from tools like Mailchimp or Klaviyo is this: those platforms are excellent at sending campaigns to a list you already have. They do not help you build the list from physical footfall. Purple Engage does both. It captures the data and runs the campaign from a single platform.
How to do it with your guest WiFi
The setup has three steps.
First, configure your captive portal. Ask for email address, date of birth (for birthday campaigns), and marketing consent. Keep the form short - two fields and a checkbox. A longer form reduces completion rates. Purple Engage handles the consent record automatically.
Second, connect your email domain. Authenticate your sending domain with SPF and DKIM records. This tells inbox providers that your emails are legitimate and improves deliverability. Purple Engage walks you through this in the platform settings.
Third, activate your first automation. Do not wait until you have a large list. Set up the "lapsed guest" automation on day one. Any guest who has not logged in for 28 days receives an automated email with a specific offer. The list will be small at first. It grows every week.
For pubs and bars already running hardware from Cisco Meraki or HPE Aruba, the integration is a cloud configuration. No engineer visit required.
What to send, and when
The campaigns that drive the most return visits for bars and pubs fall into four categories.
The lapsed guest email. Trigger: no WiFi login for 28 days. Content: a specific offer valid Tuesday to Thursday, such as a free side with any main or a discount on a round. Subject line: "We haven't seen you in a while." This email targets warm leads - people who already know and like your venue - with a reason to return on a quiet night. Stonegate Pubs uses this type of behavioural trigger across their estate to reduce the gap between visits.
The birthday campaign. Trigger: 14 days before the guest's birthday. Content: a free bottle of prosecco or a round on the house for a table booking of six or more. This drives group bookings, which are the highest-revenue visits for most venues. A free bottle of prosecco costs you roughly £8 at trade. A table of eight spending £30 each is £240 in revenue.
The quiet night push. Trigger: manual send, Tuesday or Wednesday morning. Segment: guests who have visited on a weekday before. Content: a time-limited offer valid that evening only. Because you are targeting guests who have already visited mid-week, the offer resonates. You are not sending a Tuesday night deal to someone who only ever comes in on Saturday.
The post-event follow-up. Trigger: 24 hours after a ticketed event. Content: a thank-you email with a link to book for the next event or a discount on their next visit. This converts one-time event attendees into regulars.
For all campaigns, keep the email short. One offer, one call to action, one link. Hospitality emails that perform well are rarely longer than 150 words.
| Campaign | Trigger | Best send time | Primary goal |
|---|---|---|---|
| Lapsed guest | 28 days since last login | Tuesday 11:00 | Mid-week footfall |
| Birthday | 14 days before birthday | Any day, morning | Group booking |
| Quiet night push | Manual | Tuesday or Wednesday 10:00 | Same-day footfall |
| Post-event follow-up | 24 hours after event | Morning after | Repeat visit |
Measuring what works
Open rates and click rates are useful for diagnosing deliverability problems. They are not the measure of success for a bar or pub. The measure of success is: did the guest come back?
Purple Engage tracks footfall attribution. When a guest who received an email subsequently logs into your WiFi, the platform records the connection. You can see, per campaign, how many recipients returned within seven days, 14 days, or 30 days. That is the number that matters.
The secondary metric is revenue per send. If you know your average spend per head and you know how many guests returned after a campaign, you can calculate the revenue that campaign generated. A lapsed guest campaign sent to 500 people with a 12% return rate and an average spend of £25 generates £1,500 in attributable revenue from a single send.
Track these three numbers per campaign: return visit rate, revenue per send, and list growth rate (new opt-ins per week). Everything else is context.

Where to start
- Audit your captive portal today. Log into your guest WiFi as a customer would. Is it asking for email? Is the consent checkbox unticked by default? If not, fix this first.
- Authenticate your sending domain. Add SPF and DKIM records in Purple Engage. This takes 20 minutes and significantly improves deliverability.
- Activate the lapsed guest automation. Set the trigger to 28 days. Write a single email with one offer. Switch it on.
- Set up a birthday campaign. If your portal is not yet capturing date of birth, add that field now. The birthday campaign is the highest-ROI automation most venues run.
- Review footfall attribution weekly. Check which campaigns drove return visits. Double down on what works.
The list builds itself from the moment you switch on the portal. The campaigns run automatically. Your job is to set the triggers once and review the footfall numbers weekly.
