Summary

This week focused on validating the end-to-end email pipeline and starting branded template work. I manually tested the full flow — enqueue → Redis signal → EmailWorkerCommandUserMailer send — for all four transactional emails (welcome, resetPassword, adminNewUser, adminCrowdsourcingPrivilege) in the dev Docker stack. I confirmed jobs move correctly through email_jobs statuses, the worker picks them up via Redis and DB fallback, and emails are delivered through Postfix. After testing, I began redesigning the HTML email templates and shared layout with consistent CDLI branding (logo header, CTA buttons, and structured admin notification tables).
