On Mac devices, a Next.js flaw resulted in an unexpected problem where clicking a mailto link repeatedly launched the Mail app by default.

In order to guarantee smooth functionality across devices, developers must also take cross-platform testing into account.

The mailto protocol facilitates the process of sending emails straight from a webpage, allowing users to quickly and easily send pre-written messages with a single click.

Creating emails from a web page is made much easier by using the mailto element, which allows users to open their email program with recipient, subject, and other information already filled in.
