Every feature designed for deliverability
From dedicated IPs to automated DNS — every component of ColdRelay exists to get your cold emails into the primary inbox.
Dedicated IPs Per Customer
Every ColdRelay customer gets their own dedicated IP addresses. Your sending reputation is completely isolated — no one else's behavior can affect your deliverability.
- Complete IP isolation from other customers
- Build and maintain your own sender reputation
- No shared infrastructure risk
- Full control over your sending footprint
Dedicated IPs Per Customer
Isolated Azure Tenants

- Separate Azure tenant per customer
- Azure Communication Services for sending
- Enterprise-grade security and compliance
- Zero cross-contamination risk
