Users appreciate the WordPress plugin for its simplicity and effectiveness in changing the admin email address without requiring email confirmation, especially when the usual WordPress process fails. They find it quick, easy, and a significant time saver. This plugin also helps bypass unresponsive old admin emails, preventing sites from being held hostage. The major drawback noted is the non-intuitive naming of the "Test Email" button, which could be confusing for some users, and rare instances where the plugin required reinstallation or canceling of pending requests to function correctly. Overall, users highly recommend it for solving a commonly frustrating issue efficiently.
