The brief
Ship a premium invite-only email outreach app with Gmail login, Hostinger SMTP, production readiness, and a polished landing experience.
What I found
Production had a hidden URL bug, SMTP config gaps, a brittle signup flow, and HTML emails that looked right in preview but not in inboxes.
What I built
I rebuilt and hardened the full stack, fixed auth and signup gating, added production SMTP support, enforced invite-only onboarding, improved the landing page, and added HTML template support with email-client warnings.
- Google OAuth login and signup gating
- Production SMTP delivery (Hostinger)
- Invite-only access control
- HTML email templates with email-client warnings
- Rebuilt landing page and brand system
What changed
The product now ships with working Google login, production email delivery, invite-only access control, a cleaner brand system, and a preview that warns when email CSS will not survive real inboxes.
