// what we do

Three problems. One stack.

Most cold email programs fail because deliverability, copy, and reply handling get treated as three separate problems by three separate vendors. We treat them as one system - because the inbox does.

01

Deliverability infrastructure

Custom sending domains. Warmed inboxes. SPF, DKIM, DMARC dialed in. Reputation monitored daily. We earn the inbox before we send a word.

02

Hand-written copy

No templates. No spintax. No AI slop. Each sequence is written by hand against your offer and your audience. Specific. Short. Worth replying to.

03

Reply handling

Real humans qualify every reply within four hours. The hot ones land on your calendar. The lukewarm ones get nurtured. The bad ones get killed clean.

// how the engagement runs

  1. 01

    Discovery + offer audit

    We pull apart your offer, ICP, and current pipeline so we know exactly who we're emailing and what we're saying.

    week 1
  2. 02

    Infrastructure + lists

    Domains warmed, inboxes provisioned, lists scrubbed and segmented. Nothing sends until the deliverability foundation is solid.

    week 2
  3. 03

    Sequences live

    First sequences ship. Replies start landing in your shared inbox, qualified within four hours, hot ones routed to your calendar.

    week 3
  4. 04

    Iterate weekly

    We test subject lines, openers, and offer angles every week. What books calls gets scaled. What doesn't gets killed.

// see if we're a fit

15 minutes. We both decide.

On the call we'll look at your offer, your current pipeline, and what the right cold email program would actually look like for you. If we're not the right fit, we'll tell you.
