Users generally appreciate the Contact Form Email plugin for its simplicity, effectiveness, and ease of use. Many highlight the robust spam deterrent features and excellent customer support, which provides prompt and helpful assistance. The plugin is praised for saving time by streamlining contact form submissions and reducing visible email addresses on websites. However, some users criticize the free version for being too limited, offering only three types of form fields and requiring upgrades for more functionalities. There are complaints about misleading marketing tactics, such as greying out options in the free version to push users towards purchasing the premium version. Overall, despite these drawbacks, the plugin is well-received for its core functionalities and responsive support.
