Email link generator (mailto): what it is for
A mailto link opens the person's email app with the recipient, subject and message already filled in, which makes quote requests and contact easier.
The tricky part is encoding: spaces, accents and line breaks must become codes like %20 and %0D%0A, as RFC 6068 defines. The tool does it for you, accepts multiple recipients, cc and bcc, warns when the link gets too long and gives you the link, the HTML button and a printable QR code.
How to use
- Fill in the recipient, subject and message.
- Copy the link or the HTML button.
- If you like, create and download the QR code.
When to use it
- Quote button on a website.
- Contact link in a signature or bio.
- QR code on a poster or menu.
Frequently asked questions
Why does the subject show strange characters?
Spaces, accents and line breaks must be encoded in the link (%20, %C3%A7, %0D%0A). This tool encodes everything the way the mailto standard (RFC 6068) requires, so the subject arrives correctly in Gmail, Outlook and iPhone Mail.
Does the link work for everyone?
It opens the device's default email app. On computers without an email app set up, nothing happens or an empty app opens, so it's good to also show the email address written next to the button.
Does putting my email on the site attract spam?
It can, because bots read page code. A contact form reduces that; if you use mailto, create an address just for the site and a spam filter.
