InfraOptimal mailboxes

You are not buying calendar and drive, you are buying sending. InfraOptimal gives your workspace its own IP from $1.00 a mailbox, so scaling from 10 to 100 mailboxes does not quadruple the bill.

  • Dedicated IP, so your reputation is yours
  • Minimum 10 slots, no setup fee
  • DNS, SSL and warmup handled for you

Phone numbers on every lead

Founder-led sales runs on calls as much as email. Reveal a mobile for the buyer you just emailed, from the same credit balance.

  • Pay 10 credits only when a number is found
  • Mobiles and direct dials, carrier checked
  • Credits roll over while your plan is active

Send from an IP nobody else touches

InfraOptimal is our own sending platform, built for cold outreach. Every mailbox gets a dedicated IP, DNS is written for you, and warmup starts on day one. 100 mailboxes run about $100 a month instead of $400 on Google or Microsoft.
