In-House Bulk Email Server Setup
Architecture, provisioning, and hardening of your own email-sending infrastructure—plus authentication, warm-up plans, and monitoring—so you control cost, scale, and data.

Own your stack
Independence from ESP throttles and pricing—tuned to your volumes and workflows.
-
Hardened & compliant
Locked-down servers, auth, and sending policies aligned to best practices.
-
Throughput ready
Right-sized MTA tuning, queues, and connection strategies for high-volume sends.
-
Full visibility
Dashboards, logs, and alerts to spot issues early and iterate safely.
What You Get
-
Requirements & sizing
Volume modeling, concurrency targets, and storage/network needs for your use cases.
-
Architecture design
Single/cluster nodes, MTAs, relays, IP pools, and role separation (edge vs. app) with a diagram.
-
Provisioning & hardening
Server build, OS tweaks, firewall rules, TLS, log rotation, and basic observability agents.
-
MTA install & tuning
Queue and retry strategy, connection caps, TLS policy, throttling, and bounce/DSN handling.

-
Playbooks & handoff
Warm-up runbook, incident checklist, deployment notes, and a short team walkthrough.

FAQs
Why build in-house vs. using an ESP?
Ownership, control, and cost efficiency at scale. We’ll outline trade-offs and where a hybrid model may fit.
Do you provide IPs or hosting?
We don’t resell either. We help you procure appropriately and configure everything with your providers.
Cloud or bare metal?
Both work. We size based on volume, budget, and compliance requirements, then harden accordingly.
What throughput can we expect?
Throughput depends on reputation, content, list quality, network, and provider limits. We size conservatively and scale with data.
Who maintains the servers after handoff?
Your team can run with our playbooks, or we can continue on a managed engagement.
