Where they pull apart

Cheap Inboxes

Stands out: MCP at api.cheapinboxes.com/mcp plus a REST checkout so agents can provision domains and mailboxes.

Watch out: The $3.50 rate is the 1-99 mailbox tier. Volume drops to $2.80 at 1,000-plus. Domains start at $2.50 per year extra.

Not the right fit for

  • Senders who need dedicated SMTP IPs they control
  • Teams that want domains included in the $3.50 rate

Hypertide

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