What each one does differently

Maildoso

$75/mo MCP API

Why it comes up: SMTP packs from $75/mo for 30 if you want MCP as well.

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

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
Buyers who want yearly mailbox billing

Senders exporting over OAuth or SMTP to Instantly or Smartlead
