Why people look past Inframail

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

What we noted

Core plan is Microsoft, not Google
No published free trial
You still pay for a sequencer

Not the right fit for

Buyers who need Google Workspace inboxes in the $147 plan
Teams that want a free trial before paying

Worth keeping in mind: Unlimited inboxes on your domains for a flat monthly fee, with SPF, DKIM, and DMARC set automatically.

What each one does differently

Mailreef

$240/mo API

Why it comes up: Dedicated server with unlimited inboxes from $240/mo plus send fees.

Stands out: Your own mail server and IP, with unlimited free inboxes and developer API access on every plan.

Watch out: The $240 rate needs a 12-month commitment. Month-to-month Agency Flex is $249/mo. Both add $0.001 per send.

Best for

Agencies sending 20k-plus cold emails a month
Teams that want a dedicated IP they control
Senders connecting to Smartlead or Instantly

Maildoso

$75/mo MCP API

Why it comes up: Per-mailbox SMTP from $75/mo if you want rotating IPs.

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

Infraforge

$4/mailbox/mo API

Why it comes up: Private dedicated IPs from $4 per slot with a REST API.

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

Mailforge

$3/mailbox/mo

Why it comes up: Shared-IP mailboxes from $3 if you skip unlimited.

Stands out: Automated SPF, DKIM, and DMARC plus mailbox slots you can delete and recreate at no extra cost.

Watch out: Minimum 10 mailbox slots. No free trial. You pay for slots even if some sit empty. Separate from Infraforge and Primeforge.

Best for

Teams starting shared-IP outbound cheaply
Senders who expect some spam complaints
