What This Skill Does

The Email Template Builder is a specialized tool for engineering teams to design, manage, and deploy robust transactional email systems. It abstracts the complexity of cross-client email rendering by utilizing React Email and MJML, ensuring that critical communications like verification links, invoices, and password resets look professional and consistent across all platforms. The skill provides a structured framework for managing multi-provider integrations (Resend, Postmark, SendGrid, AWS SES), built-in localization (i18n), and comprehensive tracking capabilities for open and click-through rates. It simplifies the developer experience with a local preview server that supports hot-reloading, enabling rapid iteration cycles without constantly triggering live email sends during the design phase.

Installation

To integrate this skill into your environment, use the OpenClaw CLI: clawhub install openclaw/skills/skills/alirezarezvani/email-template-builder

Use Cases

• Product Onboarding: Quickly generate custom welcome sequences and identity verification emails for new SaaS users.
• Billing Automation: Construct professional invoice templates and subscription renewal alerts that remain consistent with brand guidelines.
• Global Scaling: Implement multi-language support (i18n) for international users, ensuring all automated notifications are culturally and linguistically appropriate.
• Deliverability Audits: Use the built-in spam optimization checklist to improve email health and inbox placement rates.

Example Prompts

1. "Build a new React Email template for a password reset flow that uses our corporate branding colors and includes a secure, one-time button component."
2. "Add a new German localization file to the i18n directory and update the welcome template to support dynamic switching between English and German content."
3. "Configure the unified email sender to switch from SendGrid to Resend for our production environment and ensure all UTM tracking parameters are preserved."

Tips & Limitations

• Responsive Design: Always leverage the provided email-layout.tsx to maintain structural integrity; custom CSS-in-JS may cause rendering issues in older mail clients like Outlook.
• Testing: While the local preview server is powerful, always run a real-world test through tools like Mailtrap or Litmus before pushing templates to production.
• Provider Limits: Be mindful of specific provider API quotas when using the unified send interface, especially when scaling up automated email volume.
• Dark Mode: Ensure you define specific media queries for dark mode support, as not all email clients support automatic dark mode detection.
