QR Codes in Email Marketing

Using QR codes to build your email list offline

The most direct use of QR codes in email marketing is subscriber acquisition from physical materials. A QR code on a flyer, poster, or receipt that links to a simple email sign-up page converts offline interest into list growth.

For this to work, the sign-up experience must be frictionless. Landing pages that ask for name, birthday, company, phone number, and detailed preferences in addition to an email address often have lower conversion rates than pages that ask for email and nothing else on the first screen. Collect only what is essential at sign-up; additional information can be gathered in a welcome email or later in the customer relationship.

Design the landing page specifically for mobile use. Most people scanning a QR code are on a phone. A page that requires typing on a mobile keyboard should minimise required input — for email addresses specifically, use the appropriate input type to trigger the email keyboard on mobile devices.

Connecting print campaigns to email sequences

Print advertising can trigger an email nurture sequence. A QR code in a print ad, magazine feature, or direct mail piece that links to a landing page can place the visitor into an automated email sequence specific to that ad's context.

For example: a print ad in a trade publication for a software product links to a landing page. Visitors who sign up receive an email sequence about the specific use case featured in the print ad — not a generic newsletter. The QR code carries campaign context through to the email experience, creating a coherent journey from print to inbox.

UTM parameters in the QR code destination URL allow attribution — you know which print placements generate subscribers and which do not. Over several campaigns, this data informs print media buying decisions with email conversion data rather than impression estimates.

Scan-to-unsubscribe and preference management

One underused application of QR codes in email marketing is in physical communications from companies that also send digital email. A printed statement, catalogue, or physical newsletter that carries a QR code for unsubscribing or managing email preferences can reduce the number of customers who mark emails as spam because they cannot find the unsubscribe option.

This is particularly relevant for financial services, utilities, and subscription businesses that send both physical and digital communications. A QR code on a physical document that links directly to the email preference centre — bypassing the need to log in or search for an unsubscribe link — can reduce friction for customers and improve list hygiene.

QR codes in physical email receipt printouts

E-commerce confirmation emails and receipts are increasingly printed by customers who want a physical record. Including a QR code in email receipt designs (visible when printed) that links to the order status page, returns portal, or review request converts printed emails into actionable items.

This is a low-cost addition to existing email templates that creates a post-purchase touchpoint for customers who print rather than save digital copies.

Using QR codes for A/B testing print materials

Print advertising traditionally lacks the granular performance data available in digital channels. QR codes introduce that data layer. By creating two versions of a direct mail piece — identical except for different QR codes linking to slightly different landing pages — you can compare response rates, conversion rates, and email sign-ups from each version.

Different QR codes can be tracked through different UTM parameters or different destination URLs. The printing cost difference between two versions of a mailer is minimal; the data gained can inform all future print campaigns.

For meaningful A/B test results from print, ensure the two versions are distributed to comparable audience segments, not sent to different geographies or customer cohorts that may inherently differ.

Best practices for QR codes in email campaigns

When including QR codes in emails that recipients will view on a screen, consider that scanning a QR code displayed on a screen with another phone is awkward — it requires two devices. For digital email, a hyperlinked button or text link is more accessible than a QR code in the email body itself.

QR codes in emails work best in contexts where the email will be printed: transactional emails, receipts, confirmation letters, instructions for in-person events, and boarding pass-style confirmations. In these cases, the printed email is the intended medium and the QR code adds value for physical interaction.

For emails that recipients will view digitally and then take to a physical location — event tickets, appointment confirmations, boarding passes — a QR code in the email body makes sense: the recipient will have the email open on their phone and present the QR code to be scanned, not scan it themselves.
