Cold Email marketing Professional with Own Infrastructure

I am looking to hire a cold email professional who already operates their OWN warmed sending infrastructure, including:

Your own warmed domains

Your own warmed IPv4s

Your own SMTP/PMTA/MailWizz/Postfix servers

Your own rotation system (domains + IPs)

Your own deliverability setup (DKIM, SPF, DMARC, rDNS, etc.)

I am NOT looking for someone who uses Instantly, Smartlead, Mailgun, SendGrid, AWS SES, or any cloud ESP.
I am ONLY interested in professionals with a private, fully warmed system that is ready to send immediately.

Requirements:

Must send from your warmed domains (not mine)

Must use your warmed dedicated IPs (not shared SMTP junk)

Must have a working sending system already ready

Ability to send 50,000 cold emails per day (5 days a week) 1 million per month

Strong inbox placement for Gmail / Outlook / Yahoo/ and private domains

Bounce + complaint handling (FBL)

Domain rotation & IP rotation

Daily reporting

Clean suppression list management

MUST perform a 10–20 email seed test before hiring

Budget:

$500 per million depending on inboxing quality and daily volume

Long-term ongoing work for the right professional

Do NOT apply if:

You use Instantly, Smartlead, Woodpecker, Lemlist, etc.

You rely on Mailgun, SendGrid, SES, Mailchimp, or any cloud ESP

You need to warm up domains before starting

You want to send from MY domain or MY servers

You do not already own a working warmed infrastructure

To apply, please send:

A short description of your infrastructure (SMTP, PMTA, MailWizz, etc.)

Your daily sending capability (realistic numbers)

Confirmation you can start immediately

Your cost per million emails sent

And to prove you actually read this post put Christmas in the subject line

If you already have a real, warmed, private email delivery system and can send at scale immediately, I would like to work with you.
