The Stack

Four tools. One pipeline.

We orchestrate the best-in-class APIs so you don't have to glue them together.

The Brain

Anthropic

Claude turns your brand brief into safe lookalike domain suggestions with reasoning.

Domains

Porkbun

Bulk-purchase domains and auto-configure SPF, DKIM, DMARC, and MX records.

Mailboxes

Trekmail

Provision inboxes per domain and run automated warmup so you land in the inbox.

Sending

ManyReach

Senders, sequences, and prospect lists — wired up and ready to launch.

The Workflow

From zero to sending in 4 steps.

01

Write a brief

Brand name, niche, target persona, how many domains and inboxes you need.

02

Pick domains

Claude proposes 10 cold-safe lookalikes. You approve. We buy them on Porkbun.

03

Spin up inboxes

Trekmail creates mailboxes per domain, auto-configures DNS, kicks off warmup.

04

Launch sequence

Upload prospects, drop in your sequence, ManyReach sends. Track replies.

Why bother

Stop being a DNS admin.

Setting up cold outbound used to mean a week of tab-switching, spreadsheets, and praying your SPF record was right. Outbound Builder collapses that into a single brief.

Hours, not weeks

A 10-domain, 30-inbox setup takes one coffee instead of a sprint.

Deliverability by default

SPF, DKIM, DMARC, MX — done correctly, every time, automatically.

One source of truth

Domains, inboxes, senders, campaigns — all in one dashboard with live status.

Mock mode for testing

Develop your workflow without burning real money on real domains.
