Mailgo is a WordPress plugin designed to improve the functionality of mailto and tel links by presenting a modal with multiple options. Instead of the conventional behavior, users can choose from various email services like Gmail, Outlook, and Yahoo Mail, or simply copy the email address. This offers a more efficient way to handle communication links on a WordPress site.

Additionally, for telephone links, Mailgo provides options to connect through popular messaging platforms such as Telegram, WhatsApp, and Skype, or to copy the phone number directly. Although the plugin is marked as deprecated and not maintained, it still serves as a useful tool for enhancing user interaction with contact information on websites.
