Sendsets

Enables AI assistants to manage cold-email infrastructure through natural language, covering domain and mailbox provisioning, DNS setup, email warming, inbox and reply triage, exports, pre-warmed domain purchases, and webhooks. Supports hosted OAuth or local stdio installs with scoped read, write, and purchase permissions, plus two-step confirmation for anything that charges a card.

Email for AI agents. Create inboxes, send and receive emails without phone or CAPTCHA. Inboxes are server-readable, not end-to-end encrypted.

Enables AI agents to autonomously create email accounts, verify domains, send and receive emails, and monitor delivery events without requiring human sign-up or payment.

Enables AI agents to programmatically manage email outreach campaigns, leads, domains, senders, and webhook events, as well as send emails, through the Model Context Protocol over HTTP.
