Zapmail

Zapmail provisions Google and Microsoft mailboxes in minutes, with DNS set up and pre-warmed options. Recipients see familiar providers, and you inherit those providers’ shared IP reputation. Warmup, placement testing and monitoring are extras, so the real cost per mailbox runs above the plan price.

Infraforge

Infraforge runs private SMTP built for outreach, with slots you can fill and refill. The headline $4 slot does not include a dedicated IP: that is $99 per IP a month. It suits teams that already use the Forge suite and want to manage IPs by hand.

What 30 and 100 mailboxes cost

Monthly billing 30 / 100 mailboxes

Which to pick

  • Zapmail if you want Google or Microsoft mailboxes fast and recipients recognising the provider matters most.
  • Infraforge if you are already in the Forge suite and want fine control over many IPs.
  • InfraOptimal if you want Infraforge-style isolation at under half the price, with the IP included and monthly billing.
