Frequently asked questions
What is a mailto link?
A mailto link is a URL that starts with mailto: and opens the visitor's default email app with a new message. It can prefill the To, CC, and BCC recipients, the subject line, and the message body.
How do I add a subject and body to a mailto link?
Add a question mark after the address, then subject= and body= parameters joined with &, for example mailto:hi@example.com?subject=Hello&body=Thanks. Spaces become %20 and line breaks become %0D%0A, which this generator handles for you.
How do I send a mailto link to multiple recipients?
Separate addresses with commas, as in mailto:a@example.com,b@example.com. Use cc= and bcc= for copied recipients. This tool also accepts semicolons or new lines and converts them to commas.
Why does my mailto link show + signs or cut off the body?
In mailto links, + is a literal plus sign, not a space, so spaces must be encoded as %20. Many mail apps and browsers also truncate links longer than about 2,000 characters, so keep the prefilled body short.
Are mailto links bad for spam?
A plain email address in your HTML can be harvested by bots. A mailto link exposes the address the same way, so use a role address such as support@ or a contact form for high-traffic pages.
