Email QR code generator

What is inside the code

An email QR code holds a standard mailto link, the same kind of link used by “email us” buttons on websites. With a subject and message it looks like this:

mailto:hello@example.com?subject=Table%20booking&body=Hi%2C%20I%20would%20like%20to%20book

Spaces and punctuation are encoded so every email app reads them correctly. The generator does that for you, including accents, line breaks and symbols like & and ?.

Because everything is in the code itself, it works without our site and without an internet connection until the moment the person taps Send.

Good uses

• Support and returns. Print it on packing slips with the subject “Return request” and a line asking for the order number.
• Bookings and enquiries. A code on a flyer or shop window that opens “Booking enquiry” saves people typing your address.
• Feedback. Put it on table cards or receipts. For public reviews, a Google review QR code works better; email is for private comments.
• Event RSVPs and sign-ups, where a reply with a fixed subject is easy to filter. Planning a wedding? See the wedding QR code guide. For structured answers, a Google Form QR code collects them in a spreadsheet instead.
• Reporting problems in buildings, rental properties and shared spaces: “Broken light in room 4”.

Writing a message that works

• Use the subject to sort. A fixed subject like “Order enquiry” lets you set up a filter or label in your inbox.
• Prompt, do not write their email. “Hi, my order number is” gets better replies than a full paragraph they have to delete.
• Keep it short. A code with an address and a short subject is about 33 squares across and prints happily at 2.5 cm. A paragraph-long message can push it past 50.
• Avoid personal data. Do not put customer names or order details in printed codes; everyone who scans sees the same draft.

Email, text or call?

If people need an answer quickly, a text message code or a phone number code may suit them better than email. For a business card, a contact card code saves your email, phone and website in one scan, so people can choose later.

Printing and testing

Scan the finished code with an iPhone and an Android phone, and check the draft opens in the default email app with the subject and message intact. Print it at least 2 cm (0.8 in) wide for close range, with a white border around it, and add a line like “Scan to email us” so people know what to expect. For bigger prints, see the QR code size guide.
