Forwarding-only domain email silently drops renewal and account notifications, causing permanent loss of the domain and all linked accounts

Summary

Indie founders and solo operators who own a domain commonly run it on a forwarding-only setup (domain → Gmail) to avoid per-seat suite costs. The hidden failure mode is that forwarding silently drops, filters, or fails to deliver critical transactional mail — especially registrar renewal reminders, security alerts, and login notices. Because the user assumes 'email still works' since daily mail arrives, they never notice the missing messages until the domain has already expired. The result is catastrophic and irreversible: a 20-year-old domain gone, and with it access to dozens of linked services (PayPal, eBay, Steam, banking, SaaS accounts) that all used that address as the recovery identity. No forwarding provider gives any guarantee of delivering 100% of inbound mail, no one notifies you that notifications are being dropped, and there is no unified 'this domain is about to expire' alert that survives the forwarding layer. This is unsolved, high-blast-radius, and exactly the failure the forwarding-only economy is built on top of.
