Email QR code generator

How to make an email QR code

1. Enter the address you want messages sent to. Check it twice, because the code can't fix a typo.
2. Add a subject line. It's optional, but it's what lets you sort and filter the replies later.
3. Add a message if it helps. A short prompt like Order number: or I'd like to RSVP for gives people somewhere to start.
4. Download it, scan it and send yourself a test email to see exactly what arrives.

What happens on the phone

The code holds a mailto link, the same kind a web page uses for an email button. When someone scans it, the phone offers to open their default mail app, whether that's Apple Mail, Gmail, Outlook or something else, with a new message already drafted.

Nothing sends on its own. The person reads the draft, can change any part of it and taps send themselves. People know exactly what they're sending, and your inbox stays free of accidental blank messages.

A phone with no mail account set up may only offer to copy the address. Print the address as plain text under the code so those people can still reach you.

Use the subject line to sort replies

The prefilled subject does more work than it looks. Give each code its own subject and you'll know where every email came from: Support: Model X200 on the product manual, RSVP: Spring Gala on the invitation, Feedback: Front desk at reception.

Set an inbox filter for each subject and replies land in the right folder before you open them. People can edit the subject, so treat it as a strong hint rather than a guarantee. Keep each subject short and plain. A label and a colon is enough.

Where email codes work well

• Product manuals and warranty cards, for support requests
• Invitations that collect RSVPs by email
• Feedback cards at a front desk or on table tents
• Catalogs and flyers for small businesses that take orders by email
• Job postings and career fair booths, so candidates can start an application email

Common mistakes

• Writing a long body. Every word adds to the code's density, and most people delete prefilled paragraphs anyway. A line or two is plenty.
• Sending replies to an inbox nobody checks. Use an address someone actually answers.
• Promising more than the code does. It opens a draft, so the printed call to action should say Scan to email us, not Scan to submit.
• Printing a personal address on public signs. A shared address like hello@ or support@ survives staff changes.

Fill in your address and a specific subject above, send yourself the test email, and set up the inbox filter before the first real reply arrives.
