Cold email infrastructure, built and operated
Cold email infrastructure setup covers domains, mailboxes, authentication, warmup, and sending architecture. We build it, verify placement, and operate it, holding 95%+ inbox placement across every campaign we run.
What we set up
Every engagement starts with the fundamentals, configured correctly the first time instead of patched later.
- SPF, DKIM, and DMARC configured and monitored across every sending domain.
- Domain architecture that separates primary brand domains from sending infrastructure.
- Mailbox strategy sized to send volume, not the other way around.
- Warmup sequencing before any domain touches a live campaign.
- Sequencer wiring so sending, replies, and data move through one system instead of several disconnected tools.
Deliverability operations
Setup is the starting point. We monitor placement continuously, run placement tests on a schedule rather than waiting for a client to notice fewer replies, and move on recovery quickly when a domain or mailbox needs attention.
Deliverability consulting
Some teams already have infrastructure in place and need a second opinion. As an email deliverability consultant engagement, we audit existing domain architecture, authentication, and sending patterns, then hand over exactly what to fix, in order, whether or not the ongoing operations work happens with us.
What breaks without it
Cold email without proper infrastructure degrades quietly. Placement drops before open rates visibly change, one misconfigured domain can affect every mailbox behind it, and warmup skipped to hit a launch date usually costs more time later than it saved.
Frequently asked questions
How long does infrastructure setup take?
Domain and mailbox setup, authentication, and warmup typically run inside the 4 to 6 week System Build engagement, though warmup continues on its own schedule before full send volume starts.
Do you work with domains and mailboxes we already own?
Yes. We audit what exists first, and only rebuild what is actually causing a placement problem.
What counts as inbox placement, and how do you verify it?
Placement means the message lands in the primary inbox, not spam or a promotions tab. We verify it with placement testing across providers, not only a sending platform's own reported number.
Can you fix a domain that already has deliverability problems?
In most cases, yes, though recovery timelines depend on how the domain was used before we take it over.
