Canadian infrastructure · monitored around the clock

Most email relays share IP addresses across all customers. Anyone can sign up and send from any address, and one spammer tanks everyone's deliverability. Your carefully crafted emails land in spam — and you have zero control.

Traditional Relay

Your emails share an IP with thousands of unvetted senders. Any one of them can get that IP blacklisted overnight.

Sender A

Sender B (you)

Shared reputation — all affected
