Enterprise Infrastructure

Your Email.
Your Cloud.

Enterprise includes private deployment lifecycle management for single-tenant, dedicated, hybrid, and on-premise models. We track region, isolation, health, dedicated IPs, and BYOIP verification from design through launch.

Performance Benchmarks

Reduced Network Latency

When your application and email infrastructure share the same network, the API path stays close to your workload and is easier to measure.

Illustrative deployment scenarios. Actual latency depends on your network topology and region.

Private CloudSame VPC

Sub-millisecond — app and API share the same network fabric

Private CloudSame Region

Low single-digit milliseconds — minimal cross-AZ hops

Shared CloudCross-region API

Tens to hundreds of milliseconds — public internet traversal

Third-party SaaSExternal HTTPS API

Variable — DNS, TLS handshake, and internet routing added

Private Cloud
Same Region
External API
VPC-Collocated
App and API within the same private network — no public internet hops
Zero Egress
Traffic stays within your VPC, reducing cost and exposure
Predictable P99
No shared-tenant jitter; latency scales with your own infrastructure
Deployment Options

Deployment Options

Start on shared cloud, then review dedicated and custom deployment models when your security and compliance requirements call for them.

Shared Cloud

Scale SLA available

Multi-tenant infrastructure on our global edge network. Best for startups and growing companies that need reliable email delivery without managing infrastructure.

Dedicated Infrastructure

Enterprise review

Dedicated IPs and isolated operational lanes for high-volume senders that need stronger reputation control and account coverage.

Best For
High-volume senders needing IP reputation control
Included Components
Dedicated IPs
Isolated queues
Custom DKIM signing
Priority support

Private Cloud

Custom SLA review

Single-tenant deployment options scoped by region, tenancy, operations, compliance workflow, and SLA requirements.

Encryption at rest
BAA workflow
Dedicated account team

Bring Your Own Cloud

Custom SLA

Review whether ApexMail can run alongside your cloud controls, deployment process, and operational ownership model.

Best For
Organizations with strict cloud ownership and review requirements
Included Components
Helm charts
Restricted-network review
KMS integration review
Named escalation path

Enterprise-Grade Security Isolation

Dedicated deployment options can isolate email infrastructure, encryption boundaries, and monitoring paths based on a scoped architecture review.

Network Isolation

Dedicated VPC, private subnet, NACL, and security group patterns can be included when required by the deployment design.

Encryption at Rest

AES-256 encryption for stored data, with customer-managed key options reviewed for dedicated deployments.

Encryption in Transit

TLS 1.3 enforced on all connections. Opportunistic DANE and MTA-STS for outbound delivery.

Access Control

SSO/SAML integration, role-based access, IP allowlisting, and mandatory 2FA for all admin operations.

Audit Logging

Audit logs for API, configuration, and admin events with export workflows for security review.

Compliance Controls

GDPR workflows, HIPAA BAA lifecycle, and SOC 2 control evidence workflows available on Enterprise plans.

Dedicated Infrastructure

Your IPs. Your
Reputation.

Dedicated IP addresses mean your sender reputation is entirely in your hands. No shared risk, no noisy-neighbor problems, full control over warm-up and throttling.

Automatic IP Warm-Up
Gradual volume increase over 30 days to build reputation safely
Pool Management
Segment transactional and marketing traffic across separate IP pools
Reputation Monitoring
Track sender scores, blacklist status, and feedback loops
