Email QR Code

The Email QR Code generator simplifies lead generation and customer support. By encoding the "mailto:" protocol, it allows users to start an email conversation with exactly one scan. You can pre-set the recipient email address, a descriptive subject line, and even a starting body message. This removes the barrier of users having to manually type your email address, which is prone to errors. It's a perfect addition to "Contact Us" pages, product packaging for support requests, or RSVP cards for events.

Pro Tips:
  • Pre-fill subject and body to save users time
  • Works with all major email apps (Gmail, Outlook, etc.)
  • Perfect for RSVP, support, or contact forms

04Tool-Specific FAQ

How does the email QR code work?

It uses the "mailto:" URI scheme. When a smartphone scans the code, it triggers a command to open the user's default email client (like Mail, Gmail, or Outlook) and populates the fields you defined.

Will it work with Gmail or Outlook?

Yes. Because it uses a standard protocol, it will trigger whatever app the user has set as their "default" for emails on their operating system.

Can I add multiple recipients?

The standard protocol allows for multiple recipients separated by commas, but we recommend sticking to one primary address to ensure the best compatibility across all mobile email apps.

Can I include attachments?

No, the "mailto:" protocol does not support pre-filling attachments for security reasons. You should instead include a link to the file in the body of the email.
