To create an Email QR Code, use a generator like QR Code Generator or GoQR.me. Enter the recipient's email address, subject, and message body into the appropriate fields. An Email QR Code can encode data such as the recipient's email address, subject line, and body text. Apps and websites like QR Code Generator, GoQR.me, and QR Stuff can generate these codes, making it easy for users to start an email with pre-filled details by scanning the QR code.
