Managed Postmaster Services

An expert postmaster function, outsourced. InboxGenius watches your email environment, investigates when delivery degrades, escalates to relevant postmaster teams where appropriate, and works the problem until your flows are landing again.

What a managed postmaster service is

Large senders used to employ a postmaster: the person responsible for how the organization's mail behaves on the network, and the person other providers dealt with when it misbehaved. Most enterprises no longer have that role — but the work still exists, and it lands on engineering, marketing operations or nobody at all.

InboxGenius takes it on. We hold the deliverability picture across your whole environment, keep it under observation, and represent your sending to the ecosystems that decide what happens to it.

Why enterprises need it
Email failures are rarely announced. Delivery degrades quietly, and the first signal is often a business metric, not an alert.
Sending is fragmented across platforms, teams and vendors — nobody owns the aggregate reputation those systems share.
When a receiving network starts throttling or rejecting, in-house teams usually have no established route to raise it or evidence prepared to support it.

What we monitor and manage

Scope is agreed with you at the start of the engagement and adjusted as your infrastructure changes.

Reputation
Sender reputation signals

Domain and IP reputation as receiving networks see it, plus the complaint, bounce and engagement behavior that moves it.

Authentication
SPF, DKIM, DMARC and alignment

Authentication posture across every sending source, including the ones nobody remembered to tell you about.

Throughput
Rate limiting and deferrals

Where networks are slowing you down, whether your queues are absorbing it, and what your sending patterns are doing to invite it.

Rejections
Blocks and refusals

Provider and network-level rejections read in detail — response codes, affected flows, and the remediation each one actually calls for.

Placement
Inbox versus spam behavior

How placement differs by flow, audience and receiving ecosystem — and which changes to sending are moving it.

Infrastructure
Sending architecture

Domain strategy, subdomain separation, IP pools and platform mix, so one noisy flow can't take a critical one down with it.

When something breaks, we act on your behalf

Escalation is only useful if it is prepared, evidenced and routed to someone who can act. That is the work most in-house teams cannot do at speed — and the reason the retainer exists.

01

Investigate

Confirm what is actually happening: which flows, which domains and IPs, which receiving networks, since when, and against what change.

02

Identify causes

Separate the likely causes from the coincidences — reputation movement, authentication faults, list and consent problems, content and infrastructure changes, volume behavior.

03

Engage stakeholders

Work with the people who can change the outcome: your engineering and marketing teams, your ESP or platform vendors, and — where appropriate — remote postmaster teams at the receiving networks.

04

Advocate

Present your case properly: what changed, what has been fixed, and why the sending should be treated differently. Our consultants have direct access to, or established working relationships with, major postmaster teams and email ecosystem stakeholders, including Google, Microsoft, Yahoo and other networks worldwide.

05

Remediate and hold

Drive the remediation through, then keep the flow under observation until behavior is stable — and adjust sending practice so the same failure does not return.

InboxGenius does not claim guaranteed inbox placement, guaranteed delivery, or guaranteed access to every provider's internal teams. Escalation routes and outcomes vary by network and by case.

InboxGenius works on a monthly retainer basis. We do not provide hourly consulting.

A retained expert already understands your environment when something goes wrong. That context is the difference between a fast, evidenced escalation and a week of discovery — so the relationship is ongoing and strategic, not billed by the hour.
