Cold email infrastructure, set up where you send
Email infrastructure is a feature of Obert, the AI outbound platform to run your GTM in one place. It gives you the cold email infrastructure your campaigns need: sending domains, cold-email inboxes and inbox warmup. You set them up inside Obert, next to your sequences and your inbox, so there is no separate provider to manage.

Domains from one place, inboxes from another, warmup from a third, then all of it connected to the tool that sends. It is setup work before a single email goes out.
