Implement Mail Service — Welcome & Login Emails

[ayshadogo]

Description:

Use the existing Mail module to send emails to existing users:

• Welcome Message for New User
• Login Notification Email
• Create a templates folder for email templates.

Tasks:

Create src/modules/mail/templates/

• welcome.ejs
• login.ejs
• In src/modules/mail/mail.service.ts implement:
  • sendWelcomeEmail(user: { email; firstName?; username? })
  • sendLoginEmail(user: { email; firstName?; username? }, metadata?: { ip?: string; device?: string; time?: Date })
• Load and render templates with variables (name, app name, date/time, optional device/IP).
• Ensure mail configs (from env) are used (sender, subject prefixes).
• Add graceful error handling and logging (no PII in logs).

Acceptance Criteria:

• Sending welcome email renders the correct template and dispatches to the user’s email.
• Sending login email renders the correct template with optional IP/device/time.
• Uses env-driven sender & subjects.
• Unit tests pass for template rendering and mail dispatch.
• A screenshot of your server running

I would like to work on this! I'll create welcome.ejs and login.ejs templates, implement sendWelcomeEmail and sendLoginEmail in mail.service.ts with env-driven sender/subjects, render templates with the correct variables including optional IP/device/time metadata, and add graceful error handling with PII-safe logging. I'll include unit tests for both template rendering and dispatch.
