Use case · Cold email
Dedicated VPS for cold email agencies that hit inbox.
Stop fighting shared-IP roulette, Google throttling and Microsoft deplatforming. SendChief gives cold email teams a real dedicated server, persistent dedicated IPs, bulk domains and ready mailboxes that export straight to Instantly, Smartlead, Snov.io and Reply.io.
Why shared infrastructure fails
Cold email breaks on shared infrastructure
The same problems keep showing up across every cold email team we talk to — and none of them can be fixed by switching mailbox vendors.
Shared IP roulette
Every mailbox provider that pools sending IPs means one bad tenant can poison yours overnight. In 2026, shared-IP platforms are the top cause of sudden deliverability collapse for cold email teams.
Google & Microsoft throttling
Google tightened cold-sending policies in 2024 and Microsoft followed in 2026. Workspace and 365 resellers now throttle, flag, or outright suspend accounts that look like outbound sales.
Deplatforming risk
Sending thousands of cold emails from a Google Workspace tenant is an invitation to get deplatformed. Rebuilding on a new provider costs days of domain warmup and lost pipeline.
Fragmented vendor sprawl
A typical cold email setup stitches together a registrar, DNS host, mailbox vendor, warmup tool, IP monitor and sending tool. Every seam is a place something can break.
What SendChief gives you
Dedicated infrastructure, built for outbound
Every piece a cold email team actually needs — in one provisioning flow, on infrastructure you control.
Dedicated VPS per subscription
A real, isolated Linux server — no shared tenants, no noisy neighbours. You own the infrastructure your pipeline runs on.
Persistent dedicated IPv4 + IPv6
Clean, static IPs assigned to your server only. Never rotated out from under you, never pooled with strangers.
Blacklist monitoring + auto IP rotation
Continuous checks against major RBLs during provisioning and ongoing operation, with up to three automatic IP rotation attempts before handover.
Bulk domain purchase wizard
Buy dozens of warming domains in one flow at registrar rates, with DNS automatically wired end-to-end.
Workspace-per-client isolation
Agencies run every client in its own workspace — separate domains, separate mailboxes, separate reputation. One bad client never touches the others.
Free .com with every subscription
Every server subscription includes one free .com domain. No markup, no gotchas.
