United Lanes
Heyo is cold email software built for teams sending serious volume. It lets you connect unlimited sending accounts, warms them up automatically, and puts every reply into one shared inbox. The product is focused on Microsoft Exchange, which helps keep inbox costs low while scaling outreach. You can build multi-step campaigns with conditional logic, A/B testing, spintax, dynamic variables, and daily ramp-up limits. It also includes lead list management, DNS verification, compliance tools, unsubscribe pages, and a global Do Not Contact list. Teams and agencies can use it to manage outbound more efficiently without per-seat fees or inbox chaos.
