I am developing a website.
What does mailto: open in if there is no email client (like Outlook, Thunderbird, etc.)?
It works on my computer, which has Outlook, but what if one wants mailto: to open in, say, gmail.com?
What do I need to put in the mailto: statement for that to happen?
As a web developer you don't have any control over the software that a user chooses to open their email, since it's handled by that user's web browser settings, or the OS. If a user has no email program installed on their machine and no operation defined for "mailto" links in their browser, nothing would happen.
