The free and consumer-grade forwarding services exist for a reason. If you have one personal domain and a handful of addresses going to a Gmail inbox, they will probably do the job, until they do not. The failure modes are familiar: silent drops, sudden spam classification at the destination, SPF or DKIM breaking after a vendor change, the operator vanishing without notice, no support channel that responds in business hours.
Email Forwarding is built for the cases where any of those failure modes is unacceptable. Authentication-aware forwarding so the destination sees clean SPF and DKIM. Spam filtering before the forward, not after. Catch-all and multi-recipient routing as first-class features. A real support channel staffed by experts who actually know SMTP. Reasonable pricing because forwarding is plumbing, not a premium product.
The product sits inside the broader Route portfolio alongside Backup MX and Tenant Migration. The same routing engine powers all three. When forwarding is the bridge between a legacy address space and a new tenant, that path is already wired.
