Private Infrastructure

A dedicated and exclusive system used by a business for managing and sending email communications, distinct from shared or third-party platforms. Private infrastructure includes custom email servers, dedicated IP addresses, and proprietary software that allows for greater control over email deliverability, security, and compliance.

Related Terms

Cold Email

A cold email is an unsolicited message sent to introduce a product or service, build relationships, or generate leads. It should be personalized, concise, value-driven, and include a clear call-to-action.

Dedicated IP

A dedicated IP is an exclusive IP address, offering better reputation control, consistency, and custom authentication. It improves deliverability but shared IPs can benefit smaller or new senders.

Deliverability

Email deliverability is the ability to reach inboxes instead of spam. It depends on sender reputation, content quality, authentication (SPF, DKIM), and list hygiene, ensuring marketing emails are received.

Distributed Infrastructure

A distributed email system spreads resources across multiple servers to improve reliability, scalability, and performance. It enhances deliverability, balances traffic, and ensures service continuity.

DKIM (DomainKeys Identified Mail)

DKIM is an email authentication method that uses a digital signature to verify sender identity and prevent spoofing. It enhances security, improves deliverability, and protects domain reputation.
