Platform / Managed DNS
DNS hosting built for email that lands.
The most common cause of deliverability failure isn't spam filtering. It's a broken, missing, or misaligned DNS record. We host your domains' DNS and keep every record your email depends on correct, verified, and watched.
Email authentication is a chain of DNS records that all have to agree. SPF authorizes your sending paths. DKIM keys validate your signatures. DMARC declares policy and demands alignment between those two and your visible From domain. MX and PTR records make your infrastructure look coherent to a suspicious receiver. Break any single link (an SPF record past its evaluation limit, a DKIM selector that quietly expired, a DMARC record still at p=none three years in) and receivers quietly downgrade their trust in everything you send.
The cruel part is that DNS breaks silently. Nothing errors. Mail still flows. Placement just sags. So we treat DNS as a monitored, managed system rather than a setup step: generated correctly, verified to a confirmed state, and watched for drift around the clock.
The chain
Authentication is a chain. Receivers check every link.
Capabilities
What managed DNS means here.
Authoritative zone hosting
We create and host the authoritative DNS zone for each domain you bring, on redundant enterprise-grade nameservers. One controlled source of truth instead of records scattered across registrars, old wikis, and the memory of a developer who left.
The full authentication chain, generated
SPF kept inside the 10-DNS-lookup evaluation limit that silently breaks so many senders. DKIM with modern keys and managed selectors. DMARC with a policy that matches your maturity (none, then quarantine, then reject). MX and provider-verification records. All generated and published during onboarding. Nobody copy-pastes TXT records at midnight.
DMARC alignment by construction
DNS, signing, and sending live with one provider here, so the domain in your visible From header, your SPF-authenticated path, and your DKIM d= domain actually agree, in both strict and relaxed modes. Alignment is what makes authentication count at Gmail, Yahoo, and Microsoft. Unaligned mail goes to spam no matter how good the content is.
Provider verification, managed to green
Sending through Google Workspace, Microsoft 365, or the big sending platforms means publishing their ownership and authentication records, each with its own verification dance. We publish, verify, and track every one of them to a confirmed state, per domain, per integration. "Is this domain actually ready?" gets a definitive answer.
Continuous record-state tracking
Every record carries a created/verified status and gets monitored. When something drifts (a registrar change, a conflicting tool, an expired selector) it surfaces as an alert naming the record and the problem. Hours after it breaks. Not weeks after placement drops.
Change safety
Record changes go through a managed process with validation before publication. A routine edit cannot quietly push SPF over its lookup limit, orphan a DKIM selector, or contradict your DMARC policy. Those three mistakes cause most self-inflicted deliverability incidents we see.
Subdomain strategy for stream separation
Separate sending streams usually deserve separate authenticated subdomains so their reputations stay independent. We design and host that structure as part of the zone: delegations, per-subdomain authentication, policy inheritance.
Reverse DNS coherence
The sending IPs are ours, so forward and reverse DNS agree, resolve, and look like deliberate infrastructure. Strict receivers run this check before they trust a connection at all.
In practice
New client, thirty domains, sending-ready in hours rather than weeks. Onboarding provisions each zone, publishes the full authentication chain, runs every provider verification, and reports per-domain status until everything is green. The same pipeline that makes day one fast keeps year three correct.
