What we noted

$240/mo needs a 12-month term
$0.001 per send on top
No published free trial

What each one does differently

Infraforge

$4/mailbox/mo API

Why it comes up: Private IPs billed per mailbox slot instead of a flat server.

Stands out: Dedicated servers plus a public REST API at api.infraforge.ai for domains, mailboxes, and sequencer export.

Watch out: Minimum 10 slots. Extra IPs are $99 per month billed quarterly. No free trial. Separate from Mailforge.

Best for

Agencies that want private IPs they control
Teams automating mailbox setup through the API
Senders who follow strict deliverability rules

Inframail

$147/mo

Why it comes up: Flat $147/mo unlimited Microsoft inboxes without a per-send fee.

Stands out: Unlimited inboxes on your domains for a flat monthly fee, with SPF, DKIM, and DMARC set automatically.

Watch out: Microsoft-backed infrastructure, not Google Workspace. You still need a sequencer such as Instantly or Smartlead to send.

Best for

Agencies that want unlimited Microsoft inboxes
Teams tired of per-mailbox Google bills
Senders who will bring or buy domains

Maildoso

$75/mo MCP API

Why it comes up: Cheaper SMTP packs if you skip a dedicated server.

Stands out: MCP at mcp.maildoso.com plus REST so assistants can register domains and create mailboxes.

Watch out: Monthly plans skip domains ($12/year each). Cap is 1,000 mailboxes. A 30-day money-back window is not a trial.

Best for

Agencies that want cheap SMTP at volume
Teams automating inbox setup through MCP
Senders who will buy or connect their own domains

Hypertide

$3.30/inbox/mo API

Why it comes up: Google inboxes at $3.30 each with no annual server term.

Stands out: Flat $3.30 per Google inbox, no packages, plus Entra domains at $25 with 25 inboxes included.

Watch out: No free trial. Entra is the volume SKU; Google is per inbox. Month-to-month, cancel in the app.

Best for

Teams that want one Google inbox or ten thousand at the same rate
Agencies buying Entra domains at $25 for 25 inboxes
Senders exporting over OAuth or SMTP to Instantly or Smartlead
