Services / Custom Infrastructure
Infrastructure tailored to your needs, operated by our team.
When off-the-shelf doesn't fit, we design and build it. On our network, or inside your own environment. Then we run it, engineered around your volume, your providers, and your compliance needs, and aligned with industry best practices end to end.
Off-the-shelf email infrastructure assumes an average sender: one brand, moderate volume, ordinary destinations. Plenty of businesses aren't that. A platform sending for thousands of customer domains. A product whose traffic is 80% strict corporate gateways. A compliance regime that dictates where mail may flow. A volume curve that needs dedicated IP architecture warmed on a schedule. For those cases the architecture itself is the product, and it has to be designed rather than configured.
We design and build to your constraints. Domain and subdomain strategy with the authentication structure to match. Dedicated or hybrid IP pools with warming plans. Multi-path delivery topologies with ordered failover. Per-destination treatment for your actual recipient mix. The API and event integrations that connect it to your stack. Then comes the part that matters: we operate it, with the same monitoring, alerting, and managed care as everything else on our network. You get bespoke architecture with a production team attached, not a consulting PDF and a handshake.
Bespoke sending architecture
Multi-provider delivery topologies, dedicated or shared IP strategy, regional presence, and failover design matched to your traffic patterns and risk tolerance.
DNS & authentication design
Domain and subdomain strategy, key rotation, and DMARC enforcement paths built to scale with your brand portfolio.
Mailbox topologies
Provisioning models, aliasing, forwarding, and filtering designed around how your team, or your product, actually works.
Integrations
API and event integrations so Egressif fits into your stack instead of forcing you to change it.
Built in your environment when required
Some clients need the infrastructure to live inside their own boundary: their cloud accounts, their network, their compliance perimeter. We design and build it there, to the same standards we hold our own network to (authentication, TLS, reverse DNS, monitoring, hygiene), and we operate or co-operate it with your team. Your auditors see your environment. Your mail gets our engineering.
Operated, not handed over
We don’t ship a diagram and disappear. What we design, we run, with the same monitoring, alerting, and managed care as the rest of our platform.
The boundary, drawn
Built where your rules require. Run to our standards.
What you get out of it
What changes for you.
Architecture with an SLA, not a PDF
We operate what we design. The diagram never gets to drift away from the reality, because the people who drew it carry the pager for it.
Your compliance boundary, respected
When the rules say the infrastructure must live in your environment, we build it there and run it to our standards. Your auditors see your perimeter; your mail gets our engineering.
Capacity that arrives warmed
Day one is production-grade: IPs warmed, authentication aligned, monitoring on. No quarter of careful ramping before the thing you paid for works.
A design that already made its mistakes elsewhere
The sharp edges of dedicated pools, multi-path routing, and volume ramps have already cut us on other projects. Your build starts past them.
