Shadow Software

Cold email, done properly.

Infrastructure and creative are two different jobs — we run both, on purpose.

The real failure mode

Most cold email fails before the first send.

A reputation problem, wearing a copywriting costume. Fix the mailbox first.

Dedicated sending domains

Outreach never sends from your domain.

Every dedicated domain carries a reply-to and redirect back to the main business — a reply always lands where you work.

Monthly subdomain rotation

One bad signal never sinks the domain you depend on.

Sending subdomains rotate on a schedule, deliberately, before reputation decays.

Custom warmup software

Warmup that targets the primary inbox.

Not the spam folder. Not a closed warmup ring. The signal that actually trains a mailbox's reputation.

DNS & deliverability audits

SPF, DKIM, DMARC — checked, then rechecked.

On the rotation schedule. Never assumed once and forgotten.

Body optimization

Copy tuned against real reply data.

What gets responses from your actual list stays. What doesn't gets cut.

Shadow Software

Infrastructure and creative. One team.
