Outreach that gets replies

Short, personal messages by email and LinkedIn — written per recipient, not per list. Follow-ups run on their own. Sending happens on dedicated domains we warm up and monitor, so messages actually arrive.

You close

Interested replies land directly with your team, with context. We sort out the no's and the out-of-office notes — you talk to people who want to talk.

What we do

One service, four parts. We build and run all of it — you review the list, then read the replies.

Target lists & enrichment

Companies that match your ideal customer profile, enriched with the details that make outreach personal — what they use, whether they are hiring, how they are growing. Built for your offer, not pulled from a database dump.

Decision-makers & verified contacts

The right person at each company, with contact details verified before anything goes out. Bad addresses hurt deliverability and waste your list — we filter them out first.

Outreach — email & LinkedIn

Sequences written in plain language and personalized per recipient. We run our own sending infrastructure: dedicated domains, proper warmup, automatic follow-ups, deliverability watched daily.

Sebastian Wallau

Founder, addscale

Before addscale, I ran automated outbound day to day at a European B2B online marketplace — target research, personalization at scale, sequences, deliverability. Operationally, not in theory.

Today I build and run the same systems for my clients: own sending domains, proper warmup, verified lists, copy that sounds like a person wrote it. You get the interested replies — and you close.

FAQ

How do we start?
Send a short message or book a 15-minute call. You describe your situation, and we tell you honestly whether we see leverage — and where we don't. If we do, you get a concrete proposal with a fixed price. No “starting at” asterisks.
What exactly is the free list of 500 companies?
You describe your ideal customer — industry, size, region. We research 500 companies that match and send you the list. It's free and there's no obligation. The paid service is everything after the list: finding the decision-makers, verifying their contact details and running the outreach that gets them talking to you.
You're based in Germany — does that matter?
In practice, no. All the work happens remotely, we work in English day to day, and we overlap with US business hours for calls. One side effect of being German: the advertising rules here are strict, so you won't find invented case studies or made-up numbers on this page.
What makes addscale different?
Two things. Outbound is all we do — no ads, no content, no funnels — so everything is built for one job: starting conversations with the right companies. And we've run outbound operationally ourselves, at a European B2B marketplace — daily sending, deliverability, replies. We didn't just sell it.
Who provides the tools and infrastructure?
We do. Sending domains, mailboxes, warmup, workflows, integrations — set up and run by us. The tool accounts run through you, so you keep control of your data and access at all times.
What do I get, concretely?
A running system, not a slide deck: the researched target list, verified decision-maker contacts, written sequences, live sending infrastructure and simple reporting — plus ongoing operation and optimization if you want it. Interested replies land with your team.
Is this legal?
We build every campaign around the rules of the market it runs in — honest sender identity, a working opt-out, clean data sourcing. Where cold outreach is legally restricted, such as cold email inside Germany, we say so openly and plan the channels accordingly.
What does it cost?
Every system is a different size, so there is no off-the-shelf price. The usual structure is a one-time setup fee plus a monthly flat rate for running and optimizing. You get a fixed quote after the free first call — before that, we don't know what you actually need.
How fast will it run?
The list is fast — days, not weeks. Full outreach takes longer, because new sending domains have to be warmed up before they can send at volume; skip that and your messages simply don't arrive. We'll give you a realistic timeline in the first call, without empty promises.
How long am I committed?
The setup is a one-time project. Whether and for how long you keep the ongoing service is your decision. The exact terms are written into the quote before you commit to anything.
How safe is our data?
Your data runs through your own tool accounts and stays in your hands — you control access and content at all times. We don't pass anything to third parties. As a German business we work under strict data protection rules by default, and we're happy to sign a data processing agreement.
