Heyo Infra

Heyo Infra is a platform that sets up and manages dedicated cold email inboxes using your own Microsoft account. You connect your Microsoft account in seconds, point your domain nameservers, and the platform automatically configures SPF, DKIM, DMARC, and MX records. The inboxes work with cold email senders like Heyo Email, Smartlead, Instantly, and Apollo, and include inbound storage and webmail access. It is built for solo founders, sales teams, and B2B growth agencies that want to scale outbound email campaigns without paying traditional per-user markups.
