Cold email agency for B2B
A cold email agency that only hands you the replies worth a call
We find your buyers, write to each one by hand and pass you the people who want to talk. You run the sales call, we run everything before it.
The short answer
What does a cold email agency actually do?
A cold email agency runs outbound email for you from end to end: it picks who to contact, verifies their addresses, sets up separate sending domains, warms up the mailboxes, writes the messages and handles the replies. You get conversations with possible buyers without hiring anyone or learning deliverability.
The difference between agencies is what they do at the writing stage. Some load one template into a tool and send it to a whole list. We write to one company at a time and start each email with something true about that company. If we have nothing real to say to someone, they do not get an email.
It works when you sell to other businesses and a single new client is worth a real conversation. It is a poor fit for anything sold to consumers.
The problem
Why cold email usually fails when you do it yourself
The usual way
- You buy a list, and part of it turns out stale or the wrong people.
- Writing something specific to each company takes hours you do not have.
- A sending mistake can put your main domain in spam, and your normal email goes with it.
- Replies pile up, and the one interested buyer waits days for an answer.
With Ace
This is cold email, done one person at a time. No mass blast, no single template for your whole list.
- We build your list of real buyers
- We write to each person, one by one
- We warm up every inbox first
- A real person reads every reply
Step by step
How it works
- 01
We build your list of real buyers
We start with companies and people who actually match what you sell. Every email address gets verified before we ever write to them.
- 02
We write to each person, one by one
Every email opens with something true about that one company. When there's nothing real to say, we skip it.
- 03
We warm up every inbox first
New mailboxes spend weeks warming up before they send anything to a prospect, and we only raise the volume while bounces and complaints stay low.
- 04
A real person reads every reply
When someone replies with interest, we flag it and get the meeting on your calendar. Nothing here runs on autopilot, and when a lead asks us to stop writing, that's the last email they ever get from us.
Your options
A cold email agency compared with doing it in-house
Both can work. The trade-off is where the hours and the risk sit.

Example
What one of our first emails looks like
Subject: your new Denver office
Hi Dana, saw Northpeak opened in Denver last month and you are hiring two account managers there.
New regions usually mean a long stretch of cold territory before the first deals close. We could book sales calls with decision-makers in that market, without pulling your team off existing accounts.
Worth a short call to see if it fits your Denver plans?

Fit
A cold email agency makes sense if
- You sell to businesses, and one client is worth a proper sales conversation.
- You can describe your ideal buyer in two sentences.
- You already close deals on calls and want more of those calls.
- You want outbound running without hiring and training someone for it.
Look elsewhere if
- You sell to consumers or at a price that does not justify a call.
- You want the largest possible send volume at the lowest cost.
- You need meetings this week: the setup and warm-up come first.
- You cannot yet explain what you sell or who it is for.

Is cold email legal?
It depends on the country you send to, so check your own case with your lawyer before a campaign starts. The rules differ between the US and the EU, and inside the EU they vary by country. Whatever the market, we stop writing to anyone who asks, at once and for good.
Will this hurt my main domain?
We do not send from it. We set up separate domains and mailboxes and warm them up for weeks before the first prospect gets anything, so your company email stays out of the campaign.
How is this different from a tool I could buy?
A tool sends what you give it. The hard parts are deciding who to write to, finding something true to say to them and reading the answers. That is the work we do, and it is why you do not need to learn another piece of software.
Do you write the emails or just send them?
We write them. Each email is written for the company it goes to, and we agree the ideal client with you before anything goes out.
What does a cold email agency cost?
Our price and our guarantee are published on this page, so you can decide if it makes sense before you ever talk to us.
