FusionAuth allows customization of its email templates to ensure consistent branding across customer interactions, with three default templates provided for common workflows like Forgot Password, Setup Password, and Verify Email. To use these templates, users must complete SMTP configuration and ensure URLs are publicly accessible, with the option to edit or delete templates within the FusionAuth dashboard. The Email Verification template can be customized by editing base information and modifying the HTML and text versions to reflect a public URL, with a preview feature available to review changes before saving. Localization options enable communication in users' preferred languages, enhancing user experience by allowing different languages for email content. Once all modifications are made, saving the changes finalizes the updates, and the process can be repeated for each template as needed. FusionAuth positions itself as a flexible and secure Customer Identity and Access Management solution offering a range of features for free.
