Email thatlands. Systemsthat hold.

Consulting for teams whose sending volume outgrew their infrastructure. I work on deliverability, queue architecture, and the unglamorous plumbing underneath both.

What I take on

Three practices
i

Deliverability
forensics

Mail is going to spam and nobody can say why. I trace it end to end — authentication, reputation, content, cadence — and hand back a ranked fix list, not a dashboard screenshot.

  • DNS & auth audit
  • Seed-list testing
  • Reputation recovery plan
ii

Sending
architecture

Queues that drop under load, retries that stampede, workers that can't be reasoned about. Rebuilt so throughput is a dial you turn rather than a thing you pray about.

  • Queue & retry design
  • Provider failover
  • Load & soak testing
iii

Platform
review

A fortnight inside the codebase, then a written verdict on schema, boundaries, and the decisions that will hurt in eighteen months. Blunt, sourced, and specific.

  • Schema & data model
  • Service boundaries
  • Written recommendations

Transactional mail rebuild

Single-queue design collapsed on campaign days. Replaced with partitioned queues and bounded retry budgets.

Legacy ORM migration

Ten-year-old data layer moved onto a typed schema without a maintenance window or a rewrite freeze.

How it goes

Four movements

Most sending problems are not mysterious. They are simply unmeasured — and measurement is cheap once someone decides to look.

  1. Read the traffic

    Logs, postmaster tools, bounce classification. A week of evidence before a single opinion.

  2. Name the constraint

    One written document: what is actually limiting you, what it costs, and what happens if it is ignored.

  3. Ship the smallest fix

    Sequenced changes with a rollback for each. Nothing that requires a hero to operate.

  4. Leave the instruments

    Dashboards, alerts, and a runbook your team owns. The engagement should end.
