The problem

Marketing teams need to coordinate recurring customer communication without manually rebuilding every audience, message and schedule. They also need a clear place to see which workflows exist and how delivery is progressing.

What I built

YELFOX combines audience segmentation, campaigns, reusable message templates, lifecycle scheduling and delivery analytics. Its application gives staff a place to manage the work, while the automation capabilities handle repeatable communication patterns.

The gallery shows a local demo workspace with birthday, renewal, welcome and re-engagement workflows. Those examples explain the type of operational work the product supports; the capture does not show real recipients or campaign records.

Engineering focus

The reviewed technology set includes Next.js, Prisma, Better Auth, React Email and Resend, with TypeScript, Playwright and Vitest supporting the application work.

The product brings software development and automation into the same delivery: people manage the audience and campaign decisions in the application, then follow the resulting communication workflow.

Technologies

Next.js, Prisma, React Email, Resend, Better Auth.
