Moved 14 MTAs off a vendor in a weekend. Throughput went from 60k/min to 142k/min with the same iron. Suppression engine alone justified the license.
The verdict-aware routing caught a 9% VPN cohort we'd been silently sending to for months. Bounce rate dropped, sponsor revenue ticked up the next day.
I run my own iron because I don't want a vendor sniffing my list. ZetaRelay is the first self-hosted product that didn't make me regret it. Console is fast.
