Special things the platform does
We go deep on everything. The result: quality at scale - in one tool you can run yourself.
A/B Testing & Segmentation
Most cold email "testing" is one campaign, one message, one guess. You have no idea if it's the angle, the audience, or just bad luck. We fix that.
Audience Segmentation
We split your list into groups that actually matter - by industry, company size, job title, tech stack, or custom criteria no off-the-shelf tool can filter on. Each segment gets its own campaign.
Segment-Level Analytics
See exactly which audience converts - open rates, reply rates, meetings booked - broken down per segment. No more averaging your results into meaninglessness.
Different Copy Per Segment
Our writers craft distinct frameworks for each audience - not template swaps with a different line. A CFO gets a different email than a Head of Sales. Both are human-written, then AI-scaled.
Scale Winners, Kill Losers
What's working gets more volume. What isn't gets rewritten or cut. Feedback from you gets implemented within hours, not next sprint.
Parallel Campaign Testing
Multiple angles run at the same time. We're not waiting 30 days to know if something works. We test messaging, subject lines, and audience splits simultaneously.
The Proof.
7 x more meetings - per 10k contacts vs industry average.
Analytics & Retargeting
Most teams treat cold email as a one-shot channel. You send, you wait, you move on. You have no idea who was interested - just who replied.
That's a lot of signal left on the table.
Native Ad Retargeting
Every tracked link fires a pixel on click. Prospects get added to your Meta, Google, or Adroll audiences in real time. Cold email becomes the top of a full funnel.
Real-Time Dashboard
Live metrics, not monthly PDFs. Click rates, replies, meetings booked - all updated as they happen. You use the same dashboard we do. On Growth, a CSM works in it alongside you.
Individual-Level Analytics
We tell you exactly which prospects clicked what, when, and how engaged they are. Build retargeting sequences for specific clickers/repliers, trigger multi-channel nurture on LinkedIn, CRM, or ads.
Deliverability Monitoring
Microsoft SNDS, Google Postmaster, and real-time inbox placement on every email. We track every bounce, unsubscribe, spam report, and blocklist. Then fix them the moment alerts come in.
Segment-Level Analytics
See performance broken down by audience, not just campaign-wide averages. Know which segment drives replies, which drives clicks, and which to cut.
Anti-Bot Detection
We layer in timing, IP location, OS, and browser fingerprinting to filter out bots, so the click and reply numbers you see are the real ones.
The Result
16% click rate - That's thousands of people in your retargeting list.
Email Delivery
Every cold email tool runs on the same shared infrastructure. You're competing for inbox placement with thousands of other senders - including the spammers.
Proprietary SMTP with Warm IPs
Ken-managed IPs that only send Ken-quality email. Thus, they have very good reputation. Using us means you enter the good guys club.
Premium Email Warmup
No public networks like Instantly or Smartlead, which are full of spam traps and known-bad senders that train Google/MS to flag you.
Alternative Domains
We set up and manage sending domains that aren't your primary domain. They redirect to your site, sound like your brand, and keep your main domain safe & untouched.
LinkedIn Multichannel Outreach
Run connection requests, messages, and profile visits in the same campaign as email. Seats included on paid plans - no separate HeyReach subscription.
Warmup on Real Copy and Industry Leads
We warm up with the same campaigns you send, inside inboxes specific to your industry. Not the filler Google flagged years ago.
Always-Ready Backups
Spam complaints spike or a blocklist false-positives you? We swap to backups within hours. Your sending volume never drops.
Gmail Spam Algorithm Replica
We reverse-engineered Gmail's spam filter. Every email gets pre-checked before sending. If it doesn't pass, it gets rewritten until it does.
Managed Infrastructure
Domains, inboxes, servers, warmup, monitoring - all of it is handled by us. You don't touch any of it.
The Result
We ran the test ourselves. Same client, same campaigns, 250,000 emails. We moved them off shared infrastructure onto our warmup network and SMTP servers.
32% → 89% - inbox placement scores
1.7% → 3.2% - reply rate in the live campaign
LinkedIn Multichannel Outreach
Email-only stacks leave LinkedIn on the table - or force a second tool at $79/seat. Ken runs LinkedIn and email in one sequence, on seats included with your plan.
One Sequence, Two Channels
Interleave email with LinkedIn connection requests, messages, and profile visits. Same campaign editor, same approval flow, same analytics.
Seats Included, Not Metered Per Action
Starter includes 1 seat, Growth and DFY include 3. Plus one more included seat for every additional 5,000 contacts. Extra seats are $49/mo - no social-action credit mines.
Safe Daily Caps
We enforce LinkedIn's safety limits: 20 connection requests and 50 messages per seat per day (profile visits up to 80). Your account stays healthy.
Smart InMail Fallback
When a prospect has not accepted your connection, the first message can send as InMail - optionally limited to open profiles so you do not burn paid credits.
Cross-Channel Reply Handling
A reply on email stops LinkedIn steps for that lead, and a LinkedIn reply can stop the email sequence - so you never over-message warm prospects.
Free to Preview
Build LinkedIn steps on the free plan. Connecting a seat and sending requires Starter or above.
The Stack math
Instantly buyers who want LinkedIn typically add HeyReach at $79 per sender. Salesforge meters social actions that land near ~$49 per full-capacity seat.
$0 extra - for included seats on Starter and Growth
$49/mo - per extra LinkedIn seat when you need more
From cold reply to booked meeting in two clicks.
Cold email replies eat hours - OOOs, wrong-person, "not interested," half-baked questions. You either drown in it or ignore it. Either way, warm leads go cold.
Centralized Inbox
Every campaign, every reply, one dashboard. No tab-switching, no lost threads.
OOO and Wrong-Person Handling
We parse the return date and re-engage OOO leads the day they're back. "Try Sarah instead" gets handled. We find Sarah, verify her email, add her to the campaign.
AI Reply Agent
AI drafts every reply in your voice. You read, edit if you want, hit send. Never auto-sends.
Type With AI (Beta)
Type a few rough words, AI turns them into a polished, on-voice reply in one click. ~80% less time per reply.
Sentiment Analysis
Every reply tagged the moment it lands: positive, negative, OOO, wrong person. Positives get pushed to you, noise gets routed away.
Schedule Send + Save For Later
Send at 9 am their timezone, save a draft for the team to review, queue follow-ups. Timing controls built in.
Reply Open Tracking
See which leads opened your reply, how many times, and who's ghosting. No more guessing.
The Result
Tested user engagement versus Instantly, on the same campaigns, same clients.
+30% reply-to-meeting rate
20 min/day - spent on replies vs 35 min/day for the same reply volume
AI Personalization
Bad AI email is everywhere. Prospects have seen it all - the hollow compliments, the obvious templates, the "I noticed your company does X" openers. They delete before finishing the first line. The problem isn't AI. It's using AI wrong.
Multi-Point Personalization
Subject line, first line, body, and PS - each one customized per prospect. Not just a name swap. Real context woven throughout.
Spam Check
Before any email goes out, our replicated spam algorithm scans it. If it doesn't pass, it gets rewritten until it does. Every single email, every send.
Real Prospect Data
Every email is built from the prospect's LinkedIn profile and website. We pull what's actually relevant - recent posts, company updates, role changes - and use it to make the email feel like it was written for them specifically.
Trained To Sound Human
We've trained the AI to avoid AI tells - the overly formal phrasing, the perfect sentence structure, the filler compliments. It writes like a founder who spent real time on the email.
Human-Written Frameworks
Our copywriters create the structure, the angle, and the voice. AI fills in the personalized parts. The result sounds like a thoughtful human wrote it - because one basically did.
The Data
We ran our own study on engagement (clicks + replies). Same email copy, same audiences, 500,000+ emails sent across three versions:
1. No AI - Baseline. 12% engagement rate
2. Standard AI -25% - Worse than sending no personalization at all
3. Ken AI +127% - More than double the engagement
List Building & Qualification
Every list-building tool gives you the same filters. You end up with the same lists as everyone else - and you're sending the same emails to the same people.
Real qualification means reading between the lines. That's what we built.
300M+ B2B Database
20+ platforms - LinkedIn, website pages, Google search, and more. 15+ standard filters to start. Bring your own list and we'll enrich it. On the free plan you can pull up to 1,000 leads and verify emails - finding new emails is a paid feature.
Triple Email Verification
Every email address goes through three rounds of verification, including catch-alls. We filter out 65% of risky or invalid emails before you send a single one.
AI Qualification
Our AI reads each prospect's LinkedIn profile, website, and online presence - then scores them against your ideal customer profile. Filter on subjective criteria nobody else can touch.
Smart Blocklist
Upload your current clients. We auto-block your competitors. Disqualify anyone who doesn't fit - by company size, funding stage, niche, whatever you need.
The Benefit
90% qualification rate - Our clients report <10% unqualified leads.
Multichannel Sequencing
Most tools give you a dashboard and walk away. You're left writing follow-ups, managing inboxes, and bolting on a LinkedIn tool. That's not done-for-you. That's DIY with a nicer UI.
Premium Private Infrastructure
Custom SMTP servers and Outlook inboxes - not shared pools. Your emails go out on dedicated IPs we control, so deliverability doesn't depend on what other senders do.
Email + LinkedIn Steps
Add connection requests, messages, and profile visits next to email steps in one campaign. Multichannel without Instantly + HeyReach.
Smart Follow-Up Cadence
Follow-ups reference the first email and add something new. Not "bumping this to the top of your inbox." Personalized continuations that feel like a real conversation.
Self-Serve or Done-For-You
On self-serve you run the sequence, or let the AI run it and approve before it sends. On done-for-you, we write it, set the timing, monitor performance, and iterate - you don't touch the tool unless you want to.
Multi-Inbox Rotation
Every campaign rotates across multiple inboxes to stay under daily send limits and protect deliverability. Automatic. No configuration needed.
The Result
23% higher reply rate - compared to Instantly & Smartlead
