Operational Email Control With Authentication Built In
MailForge is built to support authenticated email delivery using DKIM signing and alignment with SPF and DMARC requirements, aiming to help senders pass standard authentication checks commonly used by receiving mail systems. Multi-domain support enables separate domain management with distinct DKIM keys, which can be relevant for multi-brand operations or agencies handling multiple tenants.

Monitoring, Queue Processing, And API-First Workflows
The platform includes real-time monitoring via Prometheus metrics and Grafana dashboards, providing visibility into delivery rates, bounces, and system health. For execution at scale, MailForge uses a Redis-backed message queue with priority handling, alongside worker-based delivery logic designed to manage throughput and reduce latency. A REST API supports integration for programmatic sending, campaign control, and metric access.

Built For Performance And Repeatable Delivery Patterns
MailForge is implemented in Go and emphasizes concurrency, connection pooling, rate limiting, and retry logic based on SMTP response codes. The platform also supports IP pool management, including rotation strategies and warmup support, enabling operational teams to align sending behavior with deliverability planning.

“Email delivery is often treated as a background utility until performance or reputation issues appear,” said Mahmoud Kh, Media Contact for LanxHost. “MailForge is built to give teams measurable visibility and direct control—authentication, monitoring, and delivery logic—so email operations can be managed as infrastructure, not guesswork.”
