Specialist capability

Technical outbound infrastructure in accounts you own.

Sending infrastructure, verified data pipelines, sequences, reply routing and CRM reporting. This is available when it supports a wider technical or go-to-market need; it is not an agency retainer disguised as software.

The deliverable

What you get.

  • Two or three dedicated sending domains, configured and authenticated (SPF, DKIM, DMARC). Your main domain never touches cold email.
  • A set of mailboxes, warmed up and capped at safe volumes - typically a few hundred sends per week to start, scaling as reputation builds.
  • A lead list that actually matches who you sell to: sourced from directories, registries, job boards, or Apollo - enriched, deduplicated, and every single address verified before anything is sent.
  • Sequences live in the sending tool, AI-assisted where it helps, with your sign-off on every template before it goes out.
  • Replies landing in one inbox or your CRM, bounces handled automatically, and reporting that shows which segment and which message produce conversations.
  • Documentation and handover. Everything runs in your accounts - you own the domains, the data, the tooling. Nothing depends on me to keep existing.

Who does what

My role - and yours.

  • I build: domains, mailboxes, warmup, the list-sourcing pipeline, verification, sequences, reply routing, reporting. Working, tested, documented - typically live within 2–3 weeks (mailbox warmup runs in parallel, not on top).
  • You bring: your business. Who you sell to, what a good client looks like, what tone you want to sound like. We sharpen that together in the intake - no outbound experience needed on your side.
  • Third-party tools - a data source like Apollo, a verifier like MillionVerifier, the mailboxes themselves - run in your accounts, on your cards. I pick them, set them up, and you keep them if we ever part ways.
  • After handover you can run it yourself: the documentation is written for a non-technical owner, and the weekly routine takes an hour or two.
  • Or I operate it: follow-ups handled, sequences and AI-assisted replies tuned, copy iterated on what actually gets replies, bounces and list quality watched, the CRM sync monitored - and fresh leads sourced and verified from the sources we built, at your plan's volume.
  • Either way, you own the machine. Stopping the monthly side never switches the system off.

How it works

Inputs · Process · Outputs.

Inputs

Who you sell to and what a good client looks like (we sharpen this in the intake), a few examples of deals you won and why, the tone you want, and access to your CRM if you have one.

Process

Weeks 1–2: sending domains and mailboxes go up first, because warmup takes about two weeks - it runs while everything else is built. In parallel: ICP sharpened, list sourced, enriched and verified, sequences drafted for your sign-off. Week 3: first controlled sends at low volume, watching deliverability. Then scale to a steady weekly rhythm.

Outputs

A live cold-email system in your own accounts, sending at safe volumes with verified data and your voice - plus the documentation to run it. If I operate it: a monthly rhythm of fresh verified leads and iterated sequences, with every reply routed to you.

Beyond cold email

The rest of the GTM stack.

  • Lead lists as a deliverable: a verified, enriched prospect database for your market - from registries, directories, job boards, or Apollo - delivered once, or refreshed on a schedule.
  • Buying-signal monitors: automated watchers on job postings, funding news, and tech changes that tell you which companies to talk to this week - before they start comparing vendors.
  • Deliverability rescue: when your email lands in spam - cold outreach or even quotes and invoices. Authentication fixed, reputation rebuilt, monitoring in place so it stays fixed.
  • GTM reporting: one dashboard showing which channel, segment, and message actually produce deals - pulled live from your CRM and tools, not assembled by hand every Friday.

Stack

What we'd actually use.

  • Google Workspace mailboxes
  • Apollo / registry data / custom scrapers
  • MillionVerifier (email verification)
  • Smartlead or my own sending platform
  • Laravel pipelines for sourcing + enrichment
  • HubSpot / Pipedrive API
  • Targeted LLM calls for research and personalisation

Why clients hire me

Senior development with an operator’s sense of consequence.

This is the exact system I run for my own products every day - warmed mailboxes, sourcing pipelines, verification, sequencing. I'm not reselling a course or a tool: I build for you what I already operate for myself.

  • Five years of technical ownership for the Laravel platform behind a Belgian lead-generation business.
  • A live €100k+/month ecommerce migration onto a new Shopware store built from scratch.
  • Long-term work on two Magento stores across custom features, integrations, performance, security and operations.
  • A multi-tenant Laravel SaaS in active development with billing, queues, crawling, search data and AI workflows.
  • Building on the web since 1997 with more than fifteen years in production PHP/Laravel and ecommerce systems.

Recent work

A platform that ran for five years.

2021 - 2026
Real-estate lead generation, Belgium

Built and operated the software behind a Belgian lead-generation business for five years.

A roughly €2,000 first build became five years of technical ownership: six-plus lead sources, CRM integrations, custom billing, lifecycle email and thousands of leads per month.
