Inbound brings the people already looking. Outbound goes after the specific companies you want, and runs right alongside it.

Why outbound stalls
Good outbound is five jobs at once: finding the right people, writing emails worth replying to, keeping your domains out of spam, following up on time and answering replies before they go cold. In most companies all five land on one person as a side task, and it quietly stops a few months in. We run the whole thing as our job, every week.
What we do
One team owns it from the first list to the booked meeting, so nothing falls between tools or people.
We define who you sell to with you, then build verified lists of the decision makers at those companies.
Short, specific emails written for each audience. Nothing goes out until you've approved it.
Separate sending domains and inboxes, set up and warmed properly, so your main domain is never at risk.
Multi-step sequences that keep going on schedule, at a sending pace that protects deliverability.
We answer replies quickly, handle the back and forth, and put qualified meetings straight on your calendar.
Clear reporting on what's sent, opened, replied and booked, and we keep tuning what works.
How it works

We agree your ideal customers and the offer with you, then build the lists and write the sequences for your approval.

We set up and warm your sending domains and inboxes, which takes two to three weeks, then launch and run the outreach every day.

Interested replies get answered and booked onto your calendar. You show up to the call and do what you do best.
Fair questions

Recruiting and ramping a new SDR takes time, and the know-how leaves when they do. We bring the process, the infrastructure and the people from day one, and the system stays in place.

Software gives you a place to send from. It doesn't decide who to contact, write emails people answer, protect your domains or reply when someone says yes. That's the work we do.

FAQ
No. We set up separate sending domains and inboxes for outreach, so your main domain's reputation and your everyday email are never at risk.
New inboxes need two to three weeks of warmup before they can send at full volume. We use that time to build your lists and write the sequences, so outreach starts as soon as the inboxes are ready.
We do, based on what you tell us about your customers and your offer. You review and approve everything before it's sent.
No. We set up and run the sending platform, domains and inboxes. You get the meetings and the reporting, not another tool to learn.
A monthly fee for the service, plus the sending infrastructure, which grows with how many people you want to reach. You can estimate the infrastructure side yourself with our email cost calculator.

B2B cold email is widely used, but the rules differ by country. We contact business addresses only, include a simple way to opt out in every email, and honour opt-outs straight away. We set campaigns up for the markets you sell into.
