Perfect. Okay. So the plan now is to start the outreach and see how that goes.

Can you do me a favor and send me some samples of the emails that you're sending out? I did get one from a friend of mine.

Cold email outbound engine at a glance

Challenge
Founder-led firms need conversations from cold channels without burning their primary domain, and most outbound tools sell unreproducible reply rates.
Solution
Lists cleaned before any send, warmed secondary domains, persona sequences and a weekly deliverability read, run on our own pipeline first.
Result
247 qualified leads handed to the pipeline from about 225K recipients a month, July to October 2025, on lists cleaned before every send.

The cold email outbound engine challenge

Founder-led firms need qualified conversations from cold channels without burning their primary domain, and most outbound tooling is sold on reply rates nobody can reproduce. So we built the engine for ourselves first and ran it at volume before putting it in front of a partner or a client.

What went into the cold email outbound engine

Outbound and emailData pipelineWorkflow automation

  1. Contact lists built in Apollo, then cleaned with a commercial service and later with our own engine

  2. A 4 March 2026 operations session cleaned a 12,000-contact list to about 4,700 verified addresses before any send

  3. Secondary sending domains with SPF, DKIM and DMARC, warmed before use, so the primary domain never carries cold mail

More of what we built7
  1. Sequenced, persona-segmented copy: ten templates tested on our own program, one five-step sequence kept

  2. Our own program, July to October 2025, through five Salesforce Starter accounts and one third-party sending app

  3. Reply triage and qualified-lead hand-off, with weekly deliverability reporting

  4. An MQL hand-off rule from the 4 March session: Ali replies, CC the closer and BCC the founders

  5. The same engine run for a partner under their brand from October 2025, with templates reviewed and a response-time process agreed

  6. A client pilot, February to May 2026: a 13,000-row list cleaned to 8,869 contacts, two domains warming, 15 sending seats and a daily send cap

  7. Our 2026 rebuild: ten mailboxes across five domains on Hostinger with Cloudflare name servers, a 42-combination offer-by-segment grid, sequences staged before activation, and a weekly deliverability report per domain

Cold email outbound engine results

The playbook we sell, the sequence, the list cleaning and the deliverability routine, came out of a program we paid for ourselves and ran at volume for four months before a client saw it.
