As the creator of CoreUI, a widely used open-source UI library, I’ve implemented email functionality in countless Node.js applications throughout my 11 years of Node.js development. The most reliable approach is using Nodemailer with SMTP configuration, which provides a simple API for sending emails through any email service. This method is widely adopted and supports all major email providers.
