The sending infrastructure that keeps you out of spam.
Your campaigns are only as good as the pipes they flow through. We build, manage, and monitor the entire sending stack so you never think about deliverability again.
Infrastructure is the unsexy part that makes everything work
Most outbound teams treat infrastructure as a checkbox: buy some domains, set up DNS, start sending. Then they wonder why reply rates are under 1%. Deliverability isn't a one-time setup. It's an ongoing engineering discipline. Domain rotation, IP reputation, authentication protocols, bounce handling, complaint loops, blocklist monitoring -- we manage all of it so your campaigns actually reach the people you're trying to talk to.
What we build and manage
- 1
Domain architecture
We purchase, configure, and manage dedicated sending domains that protect your primary domain reputation. Domains are rotated on a schedule based on volume and health signals.
- 2
Authentication stack
SPF, DKIM, DMARC, BIMI, custom tracking domains, and MX records -- all configured correctly from day one. We monitor authentication pass rates across every provider.
- 3
Inbox health monitoring
Daily seed tests, blocklist scans, reputation score tracking, and bounce rate monitoring. We catch deliverability issues before they become problems.
- 4
Ongoing maintenance
Domain rotation, inbox replacement, DNS updates, provider-specific tuning, and incident response. We treat your infrastructure like production systems because they are.

Frequently asked questions
Do I keep the domains if we stop working together?
Yes. All domains purchased for your campaigns are transferred to you at the end of the engagement. We'll provide full DNS documentation.
How do you handle blocklisting?
We monitor all major blocklists in real time. If a domain gets listed, we initiate removal requests immediately and rotate the affected domain out of active campaigns within hours.
Can you manage infrastructure I already have?
Yes. We'll audit your existing setup, fix any issues, and bring it under our monitoring. If some domains are healthy, we'll keep them. If they're burned, we'll replace them.
