Mailto Link

You can use a mailto: command to open respondents' default email client to send an email. To set this up, simply add a mailto: command to your link's action as an external URL. For example, if you want your link to open an email that will be sent to ion@rockcontent.com, the external URL for your link can be set to mailto:ion@rockcontent.com.

You can also append a subject line using a query string variable. For example, if you want the subject line of the email to be "Help," you can use the below mailto command which includes a "subject" query string variable.

mailto:ion@rockcontent.com?subject=Help

To take things a step further, you can also pre-populate the body of the email by appending another query string variable. If you want your email to pre-populate with the message "Please help me," you can append it to the mailto command using a "body" query string variable.

mailto:ion@rockcontent.com?subject=Help&body=Please+Help+Me
