Typing an email address correctly on a phone keyboard, then a subject, then a message — that's three chances to make a typo. An email QR code fills in all three, and the person only has to review and hit send.
What to pre-fill
Address is essential. Subject line is worth setting too — it lets you route replies ("Warranty claim" vs "General question") without asking the sender to remember to type it. Body text is optional; a short prompt like "Order number: " saves them a step without writing the whole message for them.
Where it works better than a vCard
A vCard saves your contact card broadly. An email QR code does one specific thing: open a compose window aimed at you, right now. Use it on a support page, a warranty card, or a "questions? email us" sign — not as a general "add us to your contacts" tool.
Test on both major phones
Our generator encodes the subject and body correctly, but always test-scan on both iPhone and Android before printing — different mail apps handle the pre-filled draft slightly differently.
