Domain and mailbox provisioning platforms that keep cold outbound infrastructure warm and deliverable.

Where a point solution breaks
- Warm-up runs on a fixed schedule regardless of your actual sending volume or domain age — it's a generic ramp, not a tuned one
- Provisioning new domains and mailboxes is still a manual, repeated setup task even though the warm-up itself is automated
- None of these tools tell you when a domain's reputation is degrading because of something happening in your actual send pipeline, not theirs
Inbox infrastructure tools keep domains warm in isolation from what you're actually sending. An embedded engineer connects domain health monitoring directly to your sending pipeline, so throttling and rotation respond to real deliverability signals, not a generic timer.
