Define the search space
We narrow down who you want to reach: industry, size, role, trigger. Without that boundary every list becomes arbitrary — and every analysis worthless.
Cold mailing as infrastructure
Find. Verify. Reach out.
Outreach that lands.
We build and run the whole chain: search space, list building, qualification, delivery infrastructure, sequences, reply classification. You get replies — pre-sorted, in one inbox. You do the talking.
We identify, qualify, contact, analyse and scale your outreach.
Reach is not the goal. The right reply is.
Email enough addresses and you will eventually get replies. We work the other way round: sharpen the search space first, verify the list, then deliver. What is not qualified does not get contacted.
Precision over volume.

Every stage countable, not just the last one.
From search space to reply you see how much survives each stage. Where something is lost, it is visible — not only at month end.

18Worked example illustrating the chain. Not client data, not a committed rate. Real figures depend on search space, offer and starting position.
The chain
Six steps we take over in full.
You operate no tool. We run the chain and hand you the replies — read and sorted.
Build the list
We assemble companies and contacts ourselves rather than taking over a purchased file. For every record it stays traceable where it came from and when it was verified.
Qualify
Addresses are verified, duplicates removed, roles confirmed. Your existing customers, open deals and blocked companies are cross-checked before every send. What fails the check does not get contacted.
Delivery infrastructure
Dedicated sending domains, warmed mailboxes, SPF, DKIM and DMARC in place, limited volume per mailbox. Your main domain stays out of cold sending. Delivery is engineering, not luck.
Sequences
Plaintext, one sender identity per sequence, a clear reason in the first sentence. No image, no signature graphic, no tracking pixel on first contact.
Classify replies
Every reply is collected and classified so you can spend your time on the leads that matter. You open an inbox that is already sorted — instead of judging each response yourself. The replies you write, because the conversation is yours.
How we work
Precision over volume.
We are infrastructure, not growth coaching. These four commitments decide how we operate.
What we stand behind is the method
Nobody can credibly predict how a market reacts to an approach. We therefore commit to no reply rate — we open up every stage instead, so you can do the maths yourself.
Your existing customers stay untouched
Suppression lists are mandatory, not optional. Existing customers, open deals and every unsubscribe are cross-checked before each send — continuously, not once at the start.
We stop what does not carry
Every sequence has stop and scale criteria agreed up front. If a campaign runs below the threshold we stop it and tell you why — rather than letting it run on quietly.
Your main domain stays clean
Cold sending runs on separate sending domains. The reputation risk sits with us, not in your internal mail traffic.
Contact
Let us talk about your search space.
In the first call we narrow down who you want to reach and tell you whether we can build the chain for it sensibly. If we cannot, we say so — and you still walk away with a sorted search space.

Questions
What you are probably going to ask.
Do we get software or an account?
An account. LeadSeek is a service, not a tool you have to operate, configure or learn. You receive an inbox in which every reply is already sorted. Lists, sequences and delivery figures are run by us — you get visibility at any time.
Who answers the replies?
You do. Every reply is collected and classified so you can spend your time on the leads that matter. What gets written after that comes from you — with your name, your tone and your knowledge of your own offer. Cold mailing brings the conversation to the table. You should be the one having it.
Where do the addresses come from?
We build the list for your search space ourselves instead of buying a finished file. It is based on our own scrapers and algorithms as well as lists compiled to order by contracted researchers. For every record it stays traceable where it came from and when it was last verified.
Is this legally sound?
We contact business people in their professional role only, name the sender and the reason in plain text, and can evidence the origin of every record. Every mail carries an opt-out; an unsubscribe lands on the suppression list immediately and permanently. The legal assessment of your specific case is one you make with your legal team — we supply the evidence they need for it.
Does sending run through our domain?
No, and that is deliberate. We register dedicated sending domains close to your name and warm them up. The recipient sees your company, your sender and your signature — only the technical delivery runs separately. Your main domain therefore stays out of cold sending.
How do you make sure the mails arrive?
Warmed mailboxes, SPF, DKIM and DMARC records in place, limited volume per mailbox and continuous monitoring of delivery figures. Plaintext without images and without a tracking pixel on first contact helps as well.
When does the first mail go out?
Expect two to four weeks between start and first send. In that time domains are registered, mailboxes warmed, and the first list built and verified. Sending earlier burns the deliverability you are still building.
What do we need to provide?
A kick-off call on the search space, your suppression list with existing customers and open deals, sign-off on the sequence copy — and after that a person who reacts to the classified replies. The ongoing effort on your side is in replying, not in operating.
How do we see whether it works?
From the figures at every stage, not just the outcome: search space, list built, qualified contacts, delivery, replies and how they were classified. You get those numbers on a fixed rhythm, together with our read on what we stop, hold or scale.
