Email QR code generator
This email QR code opens a new message with the address already filled in, so the reader only has to tap send. Add a subject and a starting message if you want to save them a few taps too.

How an email QR code opens a ready-made draft
A mailto QR code works like the Contact us link on a website, carried in a code instead of blue underlined text: scan it, and the phone's own mail app opens a draft, addressed and ready to send.
What an email address QR code stores
The recipient is the only required part - leave subject and message blank and scanning it opens a blank draft to that one address. The code only opens the draft, though: nothing sends until the reader reviews it and taps send themselves in their own mail app.
1mailto:2hello@rowanvale.example3?subject=Booking%20enquiry4&body=Hi%2C%20could%20I%20book%20a%20table%20for%20four%3F
- mailto: tells the phone this is an email address to open, not a website or plain text.
- Address the recipient, typed exactly as it should appear in the To field.
- ?subject= fills the subject line; a space becomes %20 automatically.
- &body= fills the message body the same way, punctuation included.
What this QR code for email fills in - and what it leaves out
This generator builds three fields: the recipient, subject and body. A carbon copy or blind copy is not something a scan can add - the reader would need to add that themselves once the draft is open.
| Field | In this generator | Notes |
|---|---|---|
| To | Yes | Required - the code does nothing without a recipient. |
| Subject | Yes | Optional; left blank if you do not set one. |
| Body | Yes | Optional; a good place for a short template the reader can edit. |
| Cc / Bcc | No | Add these in the mail app after the draft opens. |
Spaces and punctuation in the subject and message
A space, comma or question mark cannot sit inside a mailto link as-is, so this generator converts them to a %20 or %2C style code automatically - you never type the encoded form yourself, and every mail app decodes it straight back to plain words.
Breaks
A subject typed as Booking enquiry - stored unencoded, which breaks the link at the space.
Works
The same subject stored as Booking%20enquiry, which every mail app reads back as Booking enquiry.
This generator does the encoding for you - shown here only so the link in the code is not a mystery.
Where an email QR code saves the most typing
Feedback card
Left on a table or in a welcome pack, with a short prompt already sitting in the message body.

Press enquiry
On an event poster, addressed straight to press contacts instead of a general enquiries inbox.

Mail apps change how they present a draft; if a subject or message does not appear as expected, the app's own help pages have its current behaviour.
Email QR code questions
No. It opens a draft with the address, subject and message already filled in - the reader still reviews it and taps send themselves.
Whichever app the phone treats as its default for mailto: links - often Mail on iPhone or Gmail on Android, depending on the reader's own settings.
Not from this generator - it builds the To, subject and body fields only. Add Cc or Bcc once the draft is open.
Only loosely, as a well-formed address; nothing checks the mailbox actually exists, so a typo builds a working code for the wrong address.
Yes - it is the identical mailto: format used behind a Contact us link, just carried in a code instead of underlined text.
