# Sendbox Docs

> Sendbox is dedicated cold-email infrastructure: your own IPs and mailboxes, real inbox warmup, deliverability monitoring, and a full sending/reply workflow. This site documents the dashboard, the REST API, and the MCP server that lets an LLM operate a workspace directly.

## Start Here

- [FAQ](https://docs.sendboxes.tech/faq): Yes — your own IPs and mailboxes on every plan, not a shared pool with other Sendbox customers.
- [Getting Started](https://docs.sendboxes.tech/getting-started): Sign up with email or Google. Signing up creates your first workspace — the container for your mailboxes, leads, campaigns, and everything else. You can belong to (or create) more…
- [Introduction](https://docs.sendboxes.tech/): import {   Rocket,   LayoutDashboard,   Terminal,   Cable,   Server,   Flame,   ShieldCheck,   GitBranch,   Inbox,   Users,   FileBarChart2, } from "lucide-react";

## Dashboard Guide

- [AI Reply Agents](https://docs.sendboxes.tech/dashboard/ai-reply-agents): A reply agent is a named profile — a tone, your company context, and a knowledge base — that a campaign can point at so AI-drafted replies (see Inbox) sound like you and know what…
- [Analytics & Reports](https://docs.sendboxes.tech/dashboard/analytics-and-reports): Workspace-wide totals — sent, leads emailed, opened, clicked, replied, positive replies, bounced — optionally scoped to a trailing number of days. Per-campaign stats are available…
- [Campaigns](https://docs.sendboxes.tech/dashboard/campaigns): A campaign is a sequence of emails sent to a set of leads, on a schedule, from a pool of mailboxes.
- [Domains & Deliverability](https://docs.sendboxes.tech/dashboard/deliverability): Every sending domain is checked automatically, every 6 hours, for:
- [Help & Support](https://docs.sendboxes.tech/dashboard/help-and-support): Open Help & support in the sidebar to ask for help without leaving the app.
- [Inbox](https://docs.sendboxes.tech/dashboard/inbox): Every reply across every mailbox lands in one unified inbox, grouped by conversation (lead) or viewable as a flat list.
- [Dashboard Overview](https://docs.sendboxes.tech/dashboard): The dashboard is organized around the actual sending workflow:
- [Leads](https://docs.sendboxes.tech/dashboard/leads): Leads are your contact database, separate from any one campaign — the same lead can be reused across multiple campaigns.
- [Mailboxes & Warmup](https://docs.sendboxes.tech/dashboard/mailboxes-and-warmup): Every mailbox belongs to a sending domain (derived from its email address), which is where deliverability is tracked.
- [Suppression List](https://docs.sendboxes.tech/dashboard/suppression): The suppression list is workspace-wide — an address or domain blocked here can never be sent to by any campaign, not just the one that originally caused the block.
- [Tags](https://docs.sendboxes.tech/dashboard/tags): Tags apply to both leads and mailboxes.
- [Team & Roles](https://docs.sendboxes.tech/dashboard/team-and-roles): Every member of a workspace has one role: Owner, Admin or Member.

## API Reference

- [Campaigns](https://docs.sendboxes.tech/api/campaigns): Call GET /campaigns/:id/delete-preview first to see the counts.
- [Errors & Rate Limits](https://docs.sendboxes.tech/api/errors-and-rate-limits): Every failed request returns the same JSON shape:
- [Inbox & Reply Agents](https://docs.sendboxes.tech/api/inbox): Each row of GET /replies/threads has:
- [Overview & Authentication](https://docs.sendboxes.tech/api): Base URL:
- [Leads](https://docs.sendboxes.tech/api/leads): A lead that was emailed or replied can be deleted too. Its replies go with it; the emails sent to it are kept (they count for mailbox daily limits, plan quota and bounce health).
- [Mailboxes & Domains](https://docs.sendboxes.tech/api/mailboxes-and-domains): An address warms in one workspace only. Starting or resuming warmup for an address that is already warming in another workspace returns 409 with the reason. Resuming many mailboxes…
- [Tags & Suppression](https://docs.sendboxes.tech/api/tags-and-suppression): A member calling an owner/admin-only endpoint gets 403. See Team & Roles.

## MCP (AI Access)

- [Overview & Setup](https://docs.sendboxes.tech/mcp): Sendbox exposes a remote MCP server so your own LLM — Claude, or any other MCP-capable client — can operate your workspace directly: list and add leads, build and run campaigns, wo…
- [Security Model](https://docs.sendboxes.tech/mcp/security): Some tools return content written by someone outside your workspace — most notably, the body of a reply your leads sent you. That's exactly the kind of text a bad-faith recipient c…
- [Available Tools](https://docs.sendboxes.tech/mcp/tools): The MCP server exposes 106 tools — near-full parity with the dashboard. They map directly onto the API Reference; this page groups them by area rather than repeating every paramete…

## Optional

- [Full documentation](https://docs.sendboxes.tech/llms-full.txt): every page on this site concatenated as plain Markdown, for ingestion in a single request.
