Email Hosting Technology
Our email hosting infrastructure uses clustered services, load balancing, and multi-site redundancy to ensure consistent availability and performance.
Infrastructure & Architecture
- Clustered services — Core email services (IMAP/POP, SMTP, webmail, and admin) operate in clustered configurations for high availability.
- Load-balanced access — Traffic is distributed across nodes to keep performance consistent, even during maintenance or spikes.
- Multi-facility design — Systems are deployed across multiple secure, enterprise-grade data centers with redundant power, network, and cooling.
- Scale without disruption — Capacity can be added horizontally so growth doesn’t impact uptime or speed.
Security & Protection
- Encrypted in transit — TLS is used for client connections and server-to-server delivery where supported.
- Multi-layer spam & virus filtering — Inbound mail is filtered through multiple layers to reduce junk and threats.
- Authentication standards — SPF, DKIM, and DMARC support help protect your domain and improve deliverability. Verify your records with our Mail Records Lookup tool.
- Abuse & login protections — Rate limiting and other controls help prevent brute-force attempts and account misuse.
Performance & Delivery
- Optimized MTAs — Tuned SMTP servers, authenticated outbound, and proper queue management for consistent delivery.
- Fast IMAP/POP access — Low-latency mailbox access for desktop and mobile clients.
- Modern webmail — Full-featured webmail for quick access from any browser.
Reliability & Redundancy
- No single point of failure — Redundant components and clustered services keep mail flowing.
- Rolling maintenance — Maintenance is performed without interrupting service availability.
- 99.99% uptime — Our platform and processes are designed for business-class continuity.
Data Protection & Backups
- Routine backups — Regular data protection practices help safeguard mailboxes.
- Retention options — Archiving solutions are available when you need advanced retention and e-discovery. See Additional Options on the Features page.
- DNS guidance & tools — Set up MX, SPF, DKIM, and DMARC with clear instructions; verify changes with our Mail Records Lookup tool.
Monitoring & Support
- 24/7 infrastructure monitoring — Proactive alerting and health checks keep services stable, and keep tabs on DNS mail records with MXMonitor.
- Expert help — US-based specialists focused exclusively on email.
