Bad infrastructure guarantees poor deliverability. Good infrastructure removes it as the reason. TenantCore is a cold email infrastructure platform for outbound operators and agencies. It gives you one place to set up, manage and monitor the infrastructure your campaigns depend on, without having to become an infrastructure engineer. Most operators run their sending across scattered dashboards, DNS panels and admin consoles. TenantCore brings that work into a single control surface: • Setup: connect your environments, add the domains you own, automate DNS and authentication, and create mailboxes in bulk. • Management: apply sending limits at the infrastructure level, not as a setting inside your sequencer that can be bypassed. • Monitoring: track sending activity, reputation and infrastructure health, and get alerted when something changes. • Reporting and API: see what’s happening across your infrastructure and automate it. Your infrastructure stays yours. Bring what you already have, add more through TenantCore when it’s convenient, and keep running it all from the same place as you grow across providers. TenantCore isn’t a sequencer. It works alongside the sending tools you already use, such as Smartlead, Instantly and PlusVibe, and handles everything underneath them: environments, domains, mailboxes, DNS, limits and health. Built by an infrastructure team with 10+ years running enterprise and MSP environments, for operators who treat deliverability as an engineering problem.
