The $1.50/mailbox cold email infrastructure I use to send 100K+ emails monthly

Hey everyone 👋

I've been meaning to share this with the community for a while now, and I figured it's time to stop gatekeeping this resource.

Quick context:

When I scaled our PR agency to $800K/month, one of the biggest operational costs was email infrastructure. At $8/mailbox on Google Workspace, running 300+ mailboxes was costing us $2,400/month just in mailbox fees.

The alternative I found:

There's a category of SMTP services with unmanaged IP addresses that cost $1-1.50 per mailbox/month. I'm currently running 375 active mailboxes across 75 domains through one of these services.

What you get:

• Unlimited scaling potential

• 3-click setup process

• Direct export into Instantly

• Professional SMTP infrastructure

• Full domain ownership and control

The important caveat (please read):

This is NOT for beginners. Here's why:

With Google/Microsoft, they manage IP reputation for you. With these SMTP services, YOU are responsible for maintaining sender reputation. If you get spam complaints or hit spam traps, the entire IP range gets flagged and all your mailboxes go to spam.

Who this is for:

✅ You already have a profitable cold email system with Google/Microsoft

✅ You consistently get low spam complaint rates

✅ You understand deliverability fundamentals

✅ You're ready to scale and reduce operational costs

My current setup:

I use this service alongside Google and Microsoft mailboxes to diversify infrastructure. When Google had those recent policy changes, my campaigns kept running because I wasn't 100% dependent on them.
