How do you properly construct a mailto: link without the part.
mailto:someaddress@example.com?
I dont want the address and just want whats in the parameters afterward to be filled in through the mailto.
Yes you can
mailto:?body=tisbody&subject=thisbethesubject
Did you mean
<a href="mailto:"></a>
<a href="mailto:?subject=yoursubjecthere&body=yourbodyhere">Share using Email</a>
You can use mailto in this way
<a href="mailto:user@user.com?subject=Subject&cc=CC&bcc=BCC&body=BODY">Clickme!</a>
