Email Notifications: Choose between the standard template and a simplified (image-free) template

**Problem / Use Case** All email notifications are currently sent using the default template, which contains images and graphics. In some cases, these images must be reloaded in the email client and are not displayed correctly in every email account (e.g., when images are blocked, on older clients, or in accounts with restrictions). This results in emails that look “broken” or incomplete. **Request** When sending emails, users should be able to choose between two templates: 1. **Standard Template** (current, with images/graphics) 2. **Minimalist Template** – simple, without images that need to be loaded later, which is displayed reliably and completely in every email account. **Expected Benefits** - Emails arrive readable and complete everywhere—regardless of the email client or blocked images. - Fewer “broken”/empty displays, a more professional impression. - Better compatibility and, generally, better deliverability. **General Idea** “Template” selection option for email notifications (actions). To be clarified: configurable per notification vs. a global default for the account.
