MailtoSelect is a Chrome extension developed by A&D that falls under the Browsers category, specifically as an Add-ons & Tools subcategory. This free extension simplifies the process of starting a new email by allowing users to select an email address on a webpage and initiate an email composition using their default Mail App.

The extension's functionality is straightforward; users can simply right-click on an email address, choose the "Mail to ..." option from the context menu, and a new email addressed to the selected recipient will be generated. MailtoSelect operates entirely within the Chrome browser, ensuring a seamless user experience without the need to transmit or receive any external data.
