Cold Email Infrastructure That Lands in Inbox PlusVibe is the outbound sending engine built for teams that measure deliverability, not just volume. Every workspace gets isolated sending queues, dedicated IP pools, and per-mailbox health scoring — so one bad domain never takes down the rest of your campaigns. Most cold email tools bolt on "deliverability features" as an afterthought. PlusVibe treats sending infrastructure as the product. Your warmup runs on adaptive throttling that mirrors real human behavior.
