Cold Email Has aMath Problem.

We built a system that gets 4x the reply rate and 7x the meetings.
Not by sending more, but by making every email actually worth reading. Now it's a platform you can run yourself.

The 3 Broken Models.

We've watched dozens of companies try to solve outbound. They all fall into one of three buckets and all three are broken.

The Ken Stack.

We built Ken AI to close all three gaps at once. Not a tool. Not a service. A system where every piece makes the others work better.

Multi-source data leads flow for B2B prospecting

Data

300M+ B2B leads from 20+ platforms

LinkedIn, websites, Google, and more. Not just scraping contact info - deep AI qualification on criteria that no Sales Navigator filter can handle.

"Course creators who teach finance." "Healthtech companies with bad website design." If you can describe your ideal customer and if they exist online, we can find them.

Every email gets triple-verified. We filter out 78% of risky or invalid addresses before sending a single message.

Messaging

This is where most solutions fall apart. We start with humans.

  • Our copywriters build the strategy, write the frameworks, and QA everything before it goes out
  • Real messaging crafted in your voice, for your market, with your positioning
  • Then our prompt engineers train AI models to replicate that voice for every individual prospect
  • Humans review the output at every stage
  • Each email references real details from the prospect's world. Not variable swapping.
  • Actual personalization that sounds like you spent 45 minutes on it.
Email sending infrastructure with domains and inboxes

Infrastructure

We built our own email servers on dedicated IPs

We don't use Gmail. We don't use Outlook. We built our own email servers on dedicated IPs - and they deliver 25% better than both.

Every email runs through our replicated Gmail spam algorithm before sending. If it would trigger a filter, it gets rewritten automatically. That's how we hit 80%+ inbox rates while most senders struggle to crack 50%.

Your domain is never involved. Your sender reputation stays untouched.

Continuous A/B testing workflow for cold email optimization

Iteration

We treat every campaign as a testing cycle.

Most agencies launch a campaign, check the stats, and call it done. We treat every campaign as a testing cycle.

We optimize in a specific order (more on that below) and run continuous A/B tests on every variable. After 3 months of optimization, our campaigns consistently outperform 95% of all cold email sent.

The system only works because all four pieces feed each other. Better data improves messaging accuracy. Better messaging improves reply rates. Better infrastructure means more emails actually land. And iteration compounds all of it over time.

We built this stack to run our agency. Now it's the product - you can run the same stack yourself.

The Testing Framework.

Here's something we learned the hard way: the order you test things matters more than what you test. This is how we do it.

01

Product or Service

If you're selling the wrong thing to the right person, no amount of copy will save you. We test different offers, angles, and value props before we optimize anything else.

02

List

Same offer, different audiences. A great message to the wrong people is just noise. We segment your total addressable market into 2-10 audiences and test which ones respond.

03

Messaging

Now we know what to sell and who to sell it to. We test 2-3 messaging angles per audience - different pain points, different hooks, different approaches.

04

Copy

Once the offer, list, and messaging are locked, we optimize the copy such as subject lines, length, CTAs, formatting. We don't waste budget on words when the real issue is audience fit.

The Omnichannel Picture.

Here's something we'll tell you that most cold email agencies won't: cold email works best when it's not the first time a prospect has seen your name.

Outreach is a system, not a single channel.

Ken runs email and LinkedIn multichannel in one platform - sequences, seats, and replies together. Ads, content, and phone still sit around that core. Here's the full picture:

Before Outreach Lands

  • LinkedIn content (builds familiarity with your brand and ideas)
  • Google/LinkedIn/Meta matched ads (keeps you visible to your target list)

Multichannel Outreach (What We Handle)

  • AI-personalized cold email campaigns on managed infrastructure
  • LinkedIn connection requests, messages, and profile visits in the same sequence
  • Automated reply handling across email and LinkedIn
  • Meeting booking and follow-up sequences

After Engagement

  • LinkedIn steps for clickers and warm leads who did not reply by email
  • Phone calls to warm leads (you or your team)
  • Email nurture campaigns for "not now" prospects
  • Retargeting ads on Google/LinkedIn/Meta to everyone who engaged

Frequently Asked Questions

Why most cold email fails, what the Ken Way is, and how cost compares to DIY stacks.

Agencies often run templates on weak lists. AI SDRs skip human strategy and sound generic. DIY stacks cost thousands a month plus operator hours. Without data quality, messaging craft, deliverability, and iteration together, reply rates stay near industry averages under 1%.
