Channel 01 · Cold email

Cold email that reaches the inbox and gets answered.

We set up secondary domains and warmed inboxes, build signal-based lists in Clay, and write short copy you approve. Then we send, read every reply, and tune it every week.

Designed, built and launched in 72 hours. Learn from real replies, not six weeks of planning.

Why cold email stops working

Three problems we see in almost every account before we start.

01 · Infrastructure

Burned domains

Blast a few thousand contacts from your main domain and deliverability tanks before anyone reads a word.

02 · Data

Bought lists

Scraped lists with no signal behind them. The message can’t be relevant if the list isn’t.

03 · Copy

Copy like everyone else’s

Template copy gets template results. Buyers spot it in one line and hit delete.

What’s included

The full sending system, in your accounts.

Infrastructure, list and copy are built together. Your primary domain never sends a cold email.

I've been on both sides of the table.

Hey there, I'm Josh. I've worn a lot of hats: project manager, product manager, blogger (back in the pre-ChatGPT days), cold email agency owner, GTM engineer, and then a cold email agency owner again. That loop wasn't an accident. Every detour taught me something about how B2B pipeline actually gets built, and it kept pulling me back to the thing I'm best at — which is GTM.

To date, I've sent more than 1 million emails and generated over 5,000 MQLs for bootstrapped and VC-backed companies (as of October 2026). Let's have a chat to see if GTMx can help you grow your MRR today.

Anything not covered here, bring it to the audit call.

We never send from your primary domain. We register secondary domains that redirect to yours, keep a bench of pre-warmed inboxes ready to send, and rotate sending across multiple mailboxes so volume stays safe. If a domain ever burns, your main one isn’t touched.
