GTM Engineer · Cold Email & Clay Systems

Outbound that starts conversations with the right companies.

I'm Nikhil Kashyap, founder of Leadzsurge and a GTM engineer with 5+ years building signal-based outbound systems in Clay. Hiring signals, funding data, and intent triggers find the prospects ready to buy. Sharp copy and bulletproof deliverability get them to reply.

Approach

Most cold email fails before it's sent. The list is the strategy.

01

Signal

Hiring spikes, fresh funding rounds, tech installs, intent triggers. I use Clay to find companies with a reason to buy right now, not a static list scraped last quarter.

02

System

Inbox infrastructure, domain warm-up, and deliverability engineering that keeps 10,000+ emails a month landing in the primary inbox, not spam.

03

Message

Copy personalized around each prospect's actual context: their growth stage, their hiring, their funding. Replies feel earned, not lucky.

Why

Most outbound was never going to work. Bought lists, generic copy, burned domains. The difference between spam and pipeline is engineering.

01
Data first

Signals decide who we contact, and when.

02
Deliverability always

Infrastructure decides whether we land in the inbox.

03
Message last

Context decides whether they reply.

I started Leadzsurge after five years inside the trenches of B2B lead generation, sending tens of thousands of emails and learning, campaign by campaign, what actually earns a reply.

It is never the clever subject line. It is reaching the right company in the right week with a message built from their reality. When data, deliverability, and message are engineered in that order, meetings stop being luck.

FAQ

Questions clients ask

What does a GTM engineer actually do? +

A GTM engineer builds the technical systems behind go-to-market: prospect data pipelines, enrichment workflows, email infrastructure, and automation. At Leadzsurge, that means I design outbound systems in Clay that find in-market companies and turn them into booked meetings.

What is signal-based outbound? +

Instead of emailing a static purchased list, signal-based outbound targets companies showing live buying signals: hiring spikes, fresh funding rounds, new tech installs. The list is rebuilt continuously around who's ready to buy now, which is why reply rates are 3 to 5x higher than spray-and-pray.

Does cold email still work in 2026? +

Yes, but only with engineering behind it. Deliverability infrastructure, verified signal-based lists, and context-personalized copy. My campaigns sustain 66 to 78% open rates at 10,000+ emails per month; the average untuned campaign sees under 40%.

What tools do you work with? +

Clay for data and enrichment, dedicated sending infrastructure with warmed domains and inboxes, and signal sources for hiring, funding, and intent data. Everything is built so you own the system, not rent it.
