Users appreciate this WordPress plugin for its simplicity, effectiveness, and detailed documentation when configuring email functionalities, particularly with Google Workspace (Gsuite) and Gmail. It successfully sends emails without the need for complex settings or additional credentials. Many users find it easy to follow the installation instructions and value the absence of ads, prompt customer support, and secure OAuth 2.0 protocol integration. However, some users report difficulties with initial setup, finding Google API configurations confusing, and encountering issues with specific settings or email deliveries. Complaints also include unresponsive support, occasional plugin failures, and conflicts with certain contact forms. The setup complexity could be daunting for non-technical users.
