Cold Email Infrastructure & Deliverability
Domains, mailboxes, SPF, DKIM, DMARC and warm-up: we build the technical foundation so your emails land in the inbox, not in spam.
The problem
Outreach emails end up in spam even though the copy and targeting are right. The usual causes are missing domain authentication, too many emails from brand-new mailboxes, or sending from your main domain, which damages its reputation along the way.

- SPF, DKIM and DMARC configuration
- Creation and setup of sending mailboxes
- Mailbox warm-up over several weeks
- Connection to your outreach tool
- Blacklist and deliverability checks
- Optional: ongoing monitoring of domains and mailboxes
What you get
- Authenticated sending domains
- Configured, warmed-up mailboxes
- Documentation of every DNS record
- Connection to your outreach tool
- Deliverability check before the first send

FAQ
Questions about this service
Is cold email legal?
It depends on the market. In Germany, unsolicited marketing emails are heavily restricted even in B2B (Section 7 UWG), while the UK and US have different rules. We build the technical setup; please have your campaign reviewed legally before you start.
Why not just send from our main domain?
Because spam complaints or high bounce rates would then hurt your main domain's reputation, and with it your everyday emails to customers. Separate sending domains protect your day-to-day business.
Can you guarantee inbox placement?
No, and nobody honest can. We put the technical foundations in place and monitor signals such as blacklists. Copy, list quality and volume affect deliverability just as much.
