# Datagran > Datagran is a multi-product platform for marketing measurement, AI engagement, CRM, automation, and learning. This is the public marketing-site entry point. The detailed, current AI-readable product guides live in Datagran Home. Public documentation describes capabilities; it does not grant access or prove a feature is available to a particular tenant. ## Start here Read this index first, then follow the guide relevant to the user's task. Product guides describe setup, available capabilities, and access requirements. Use the linked product-owned resources for current details. - [Datagran agent guide](https://home.datagran.io/agent.txt): Permissions, approvals, and safe workflow boundaries. - [Full AI-readable guide](https://home.datagran.io/llms-full.txt): Product summaries and task guidance. - [Product resource catalog](https://home.datagran.io/.well-known/datagran-products.json): Canonical links to product-owned resources. - [Public discovery OpenAPI](https://home.datagran.io/openapi.json): Discovery endpoints, not authorization for private operations. - [Documentation index](https://home.datagran.io/sitemap.md): Markdown guides by product. ## Personal email outreach - [Browser-readable outreach setup](https://www.datagran.io/for-ai#email-outreach): Exact navigation, input checklist, readiness checks, and paid-action boundaries. - [Inbox and outreach](https://home.datagran.io/docs/products/inbox-followups.md): Project access, reviewed automation and human handoff. - [Email outreach guide](https://api.agents.datagran.io/v1/inbox/docs.md#email-outreach-in-automations): Research companies and decision-makers, verify work addresses with ZeroBounce, and shape personal emails with Anthropic Sonnet. Add reviewed batches of 10, 20, 50 or 100 people, with at least five distinct drip steps, Billing estimates and per-email activity. - [Connect a mailbox](https://home.datagran.io/connections): A tenant administrator connects Gmail / Google Workspace or Outlook / Microsoft 365 in the Email section. In Inbox, choose Automations → New automation → Create a personal email automation to open Audience, Message and Launch. The general editor's Email channel is a different workflow. Email outreach is enabled across tenants; project access, mailbox permissions, Billing capacity and approval of each batch still apply. Every reply pauses the drip. High intent goes to Inbox, and an opt-out suppresses the person and all known addresses. Detected opens do not prove human reading. Shared verification-credit waits are uncharged and never purchase credits automatically. ## Important boundaries - Check the signed-in tenant, project, connected provider, and role before attempting setup or reading private data. - Treat external writes, messages, ad changes, and calendar bookings as separately reviewed actions. - ChatGPT Ads support is primarily measurement and attribution. Do not infer a campaign-from-scratch creation capability from this index.
