When adding a link or button which opens to an email address, it will always begin with mailto:. After you've addressed the link to one email, you can add some additional fields which are supported by most email services. Below are some of additions that you can enter after mailto:name@domain.com.
Additional 'To' Address ; - Add a Semicolon between email address
name@domain.com;robert@cerkl.com
CC - Add additional CC recipients to your email.
?cc=name@domain.com
BCC - Add additional recipients to your email that your contacts and CC'd recipients won't see.
?bcc=name@domain.com
Subject - Add a subject line to your email.
Spaces are not supported in link fields. Use "%20" to add a space between words in your subject line.
?subject=This%20is%20a%20subject
If you want to include multiple of the above fields, use "&" before adding an additional field.
Example:
mailto:name@domain.com?cc=name@domain.com&subject=This%20is%20a%20subject
