Cold email agency for B2B companies

In short: Danish Lead Co. is a fully managed cold email agency for B2B companies, founded in 2021 by Frederik Jakobsen and Martin Rasmussen and based in Aarhus, Denmark, with clients in the US, the UK and Europe. It builds and runs the whole system: verified contact data, sending domains and inboxes kept separate from the client's main domain, the copy, the sending and the reply handling, and books qualified sales meetings. In the 90 days to 23 September 2026 it sent 1,160,919 cold emails for 45 clients at a 2.58% bounce rate. Engagements run $3,000 to $6,000 per month.

1. Targeting. Your ideal customer turned into defined segments: industry, size, geography, buyer roles and the signals that make a company likely to talk now. Each segment gets its own campaign, because buyers in different segments do not answer the same email.
2. Verified data. Lists built across several data providers (we hold 16 and typically run 4 to 6 against a single list), and every address verified before it reaches the sending tool.
3. Sending infrastructure. Separate sending domains and warmed inboxes, set up and monitored by us, with SPF, DKIM and DMARC aligned. Your main domain never sends a cold email. Warmup takes two to three weeks before the first live send. We are a certified Smartlead partner.
4. Copy. Short emails for one decision-maker, one trigger and one ask, written in the buyer's language: German campaigns are written in German first, not translated. Several angles per segment, tested against each other.
5. Sending and reply handling. Controlled volume per inbox, every reply answered and qualified, and interested prospects booked straight into your calendar.
6. Reporting and iteration. Measured on positive replies and qualified meetings, not open rates. Losing angles are retired and winners get the volume.

Most cold email fails before anyone reads it, so this is the part to check first. These are the figures from the platform that runs our client campaigns day to day.

Client campaigns only; Danish Lead Co.'s own prospecting is excluded. Full method in the cold email deliverability benchmark report, reply rates in cold email benchmarks.

How the bounce rate stays there

1. Separate domains and inboxes, never your main domain. Sending runs on domains and inboxes set up for the programme. The domain your team uses every day is never used for cold email, so a bad week in outbound cannot reach it.
2. Every address verified before sending. An unverified list routinely bounces above 8%. The 2.58% is mostly verification, on every address in every campaign.
3. Authentication done properly. SPF, DKIM and DMARC aligned on each sending domain, not inherited.
4. More domains, less volume per inbox, on Microsoft-heavy lists. Microsoft 365 filters cold email harder than Google Workspace, and industrial, manufacturing and financial services lists skew toward it. In our data Microsoft 365 recipients produced 24.2% of replies, yet once they replied they were nearly as likely to be positive: 13.70% against 14.31% on Google. The gap is delivery, not interest.

United States

US work includes Harbor Access, an investor relations firm on the US East Coast, and the United States track for Grasp.gg. Danish and Swedish companies also use us to sell into the US.

United Kingdom

UK campaigns include Doshi Outsourcing, which took one offer to four UK verticals in parallel (accountancy firms, insolvency practitioners, chartered surveyors and manufacturing finance teams) with 44 first-email angles built on Companies House data, and Aureum Finance, a UK development finance brokerage run on two tracks with seven first-touch angles. Harbor Access reached LSE-listed small caps.

Europe and Germany

Danish Lead Co. is an EU company based in Aarhus, Denmark, so GDPR is the law we work under ourselves. Rules on B2B email differ between European countries, so target countries are agreed before launch rather than treated as one list. German campaigns are written in German first, as for Galvanek Bau, and Deltex BV used us to enter Germany from the Netherlands.

Full breakdown

How our outbound pricing works

Seven questions we use when we audit an underperforming programme. They work as a vendor screen too, including on us.

Who owns deliverability?

A named person who sets up and monitors authentication and domain reputation. A vague answer is the biggest single predictor of spam placement.

Where is it sent from?

Separate domains and warmed inboxes, never your main domain. Ask how many inboxes they run for you and how long they warm them.

Is every address verified first?

It should be, so bounce stays under 3%. Ask for the bounce rate across all clients, not the best campaign. Ours: 2.58% across 1,160,919 sends.

What do they report on?

Positive replies and qualified meetings. Not open rates, which are unreliable, and not emails sent, which the agency controls.

How is the copy written?

One decision-maker, one trigger, one ask, with several angles per segment tested against each other. Ask to see the angles behind a live campaign.

What happens before launch?

New domains and inboxes need two to three weeks of warmup. A plan that skips it is a plan to burn domains.

What do you keep if you leave?

Agree in writing, before you sign, who owns the domains, inboxes and lists.
