Cold outreach that reaches the inbox.And protects your main domain.
We set up dedicated sending domains and mailboxes, authenticate them, warm them up and verify every address before sending. Bounces pause the mailbox, not your campaign.
In your call: an infrastructure check, a setup plan for your domains and a realistic timeline.

The risk
One spam spike can hit your entire company.
Cold outreach from your main domain puts quotes, invoices and customer communication at risk. These are the four mistakes we see again and again.
01
Sending from the main domain
If a few recipients mark your mail as spam, your whole domain reputation suffers. Even day-to-day email ends up in the spam folder.
02
Missing authentication
Without clean SPF, DKIM and DMARC records, mail servers distrust the sender. Messages get filtered before anyone sees them.
03
A cold start at volume
A new mailbox that sends hundreds of emails at once stands out. Without a warmup phase it lacks credibility with the major providers.
04
Unverified addresses
Bounces from outdated or invented addresses drag down reputation. Without verification you only notice once the damage is done.
Isolation
Your main domain stays out of the line of fire.
Cold outreach runs on dedicated sending domains that fit your brand. Several domains spread the volume, and your main domain stays reserved for customers, team and invoices.
- 1
Dedicated domains that fit your brand
We choose sending domains that look trustworthy to recipients and match your presence.
- 2
Volume is distributed
Sending is spread across several domains and mailboxes instead of overloading a single one.
- 3
Risk stays contained
If one sending domain suffers, your day-to-day business is untouched.

Technical setup, done
DNS, SPF, DKIM, DMARC. Without you touching a line.
We add the records and check that they propagate worldwide. A mailbox only moves to the next phase once everything is verified.
- Domain setup and DNS zones
- Authentication with SPF, DKIM and DMARC
- DNS propagation check before the mailbox starts
- Mailboxes connected to your inbox in the dashboard
Warmup
Reputation grows day by day, not overnight.
New mailboxes start with low volume and realistic exchange. Volume rises step by step until the mailbox is ready for real campaigns.
- 1
Gradual ramp-up
Daily volume grows in stages and follows the mailbox's reputation build-up.
- 2
Warmup keeps running
Even during campaigns, warmup maintains reputation. A paused mailbox keeps rebuilding it in the meantime.
- 3
You see the status
Warmup day, status and health of each mailbox are visible in the dashboard.
Daily volume per mailbox
- Reply received
- Rescued from spam
- Marked important
Verification & bounce protection
Every address is checked before it can endanger your mailbox.
Before a campaign starts, we re-check addresses. Each one gets a status. If something still bounces, the system protects the mailbox and keeps your campaign running.
