Bottom line
Done-for-you Google Workspace and Microsoft 365 inboxes for outbound sending, from $3.50 per inbox per month.
Stands out for: Official Workspace and M365 inboxes with free replacements and sub-six-hour setup.
Watch out for: It supplies the inboxes only. You still need a sequencer to send, and there is no MCP.
Overview
Premium Inboxes provisions official Google Workspace and Microsoft 365 mailboxes for outbound sending. The vendor handles domains, DNS, SPF, DKIM, DMARC, sequencer upload, and warmup, and markets setup in under six hours. Unlimited free replacements are included. A public API is on all plans. There is no MCP.
Inbox quality is the real constraint for Instantly and Smartlead users. Teams pick it when they want genuine Workspace or M365 boxes, not cheap lookalike domains. Cheaper inbox vendors are listed in the same category if price is the only lever.
