Service
Email Infrastructure
Dedicated sending domains and mailboxes, properly authenticated and warmed, isolated from your primary company domain — the technical foundation cold email depends on, set up once and monitored continuously.
Where this breaks without help
Problems this service solves
Your primary domain is at risk
Sending cold outreach from your main company domain can drag down deliverability for every email you send, including support and sales.
DIY setup is easy to get wrong
Misconfigured SPF, DKIM, or DMARC records quietly tank inbox placement with no obvious warning sign.
Volume outpaces infrastructure
Scaling sends without matching mailbox and domain capacity pushes more email into spam.
No visibility until it's a problem
Without ongoing monitoring, domain health issues are usually caught only after reply volume has already dropped.
Ideal fit
Is this the right service for you?
Good fit if
- You're running, or planning, outbound at meaningful volume across multiple mailboxes
- You want sending infrastructure fully isolated from your core company email
- You need authentication (SPF/DKIM/DMARC) set up correctly from the start
Not a fit if
- You send only transactional or marketing newsletter email — that's a different discipline
- You want a one-time audit with no ongoing management (see Email Deliverability instead)

How it works
Process
A disciplined, repeatable sequence for this service — so you always know what's happening and why.

Provision
We register or connect the domains and mailboxes your sending volume requires.
- 02

- 04
Monitor & rotate
We track domain health continuously and rotate sending volume to keep patterns natural.
Getting started
What we need from you
- Ability to register new sending domains, or delegate DNS access for existing ones
- DNS access, or a technical contact who can implement authentication records
- Time for staged warm-up before full send volume begins
- Sign-off on mailbox and domain counts for your target volume
FAQ
Common questions
Why not just send from our main domain?
Cold outreach carries more deliverability risk than everyday business email. Isolating it on dedicated domains protects your primary domain's reputation if anything goes wrong.
How long does warm-up take?
Warm-up is staged gradually rather than run to a fixed calendar date — mailboxes move to full volume once sending signals show they're ready.
What happens if a domain gets blocklisted?
We monitor blocklist status continuously. If an issue appears, that domain's volume is paused and remediated rather than left to keep sending.
How many mailboxes do we need?
It depends on your target send volume and list size — we size mailbox and domain counts to your goals rather than a one-size-fits-all number.
