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

Cheap Sequencer

Stands out: Pricing is on sends alone, so adding 40 inboxes or a million contacts costs nothing extra, and it comes with its own remote MCP server so an AI agent can build lists and launch campaigns.

Watch out: The $9.99 Starter plan only works with Cheap Inboxes mailboxes; connecting your own Google or Microsoft inboxes needs Growth at $49. There is no built-in lead database or LinkedIn steps, so you bring your own list.

Not the right fit for

  • Teams that need a built-in lead database
  • Multichannel outreach with LinkedIn or calls
  • Buyers who want a free plan
