Netlify has implemented a new Email Integration feature that enables users to customize email templates, inject dynamic parameters, and preview them during development. This integration streamlines the process of setting up email triggers by allowing developers to configure email triggers and edit templates directly in their source code, resulting in time savings and reduced complexity. The integration also provides a fetch snippet for triggering emails, which can be used to send requests to an email handler for custom email templates. Additionally, Netlify Functions can be used to send emails directly from the project code, allowing developers to trigger emails based on various events such as form submissions or data changes. With this feature, developers can test and deploy their email services more efficiently, making it easier to manage email workflows in their web applications.
