Sandbox sends to the account email need no card or DNS. Sending to anyone else needs a verified domain (ownership, SPF, DKIM, return-path) and a card on file, including on the Free plan. The docs say an agent with an AgentID inbox can open its own account, which is unchecked, and sending still needs a person's card.

The MCP package went through 15 npm versions in those two days, seven of them listed in the official MCP registry. There is no public changelog, status page or deprecation policy, and the public repositories mirror a private one. The MCP README still names scheduling and cancelling tools that 0.6.3 doesn't have. Support is by email. Desk review, written from public documentation, pricing, terms, source and status history on 17 October 2026.

Pro is $20 for 50,000 ($0.40 per 1,000 at full use) with $0.90 overage, and Scale runs $90 for 100,000 to $1,150 for 2,500,000. New accounts are capped at 500 a day at first, and upgrading doesn't lift that. Whether refused sends count wasn't found.

An OAuth request that names no scope gets `full`, and confirmation before a send is left to the client. /received-emails returns full inbound messages with no prompt-injection guidance. No security.txt, disclosure policy, bug bounty or certification was found for a service launched on 16 October 2026.
