# AI Inbx

> One API to send and receive email. Replies land on the right thread as clean text, attachments as Markdown, and users can connect their own Gmail or Outlook.

Every page below is also Markdown at the same URL with `.md` appended (`/index.md` for the homepage).

## Product

- [Email API for a new era.](/index.md): One API to send and receive email. Replies land on the right thread as clean text, attachments as Markdown, and users can connect their own Gmail or Outlook.
- [Pricing](/pricing.md): Monthly plans from $5, billed by email volume. Every plan has every feature. Extra usage is $1 per 1,000 emails. No contract.

## Features

- [Every reply on the right thread](/features/threading.md): Replies with a new sender, a new subject or no headers at all still land on the thread they answer. One API call gives your agent the whole conversation, in order.
- [Every attachment, LLM-ready](/features/attachments.md): PDFs, spreadsheets, slide decks and scanned contracts arrive as clean Markdown before your webhook fires. Your agent reads the document, not a filename.
- [Send from your customer's own inbox](/features/mailboxes.md): Let your customers connect the Gmail or Outlook account they already work out of. No DNS, no subdomain — it sends and receives through AI Inbx on the same API as a domain you own.
- [Send at a pace your domain survives](/features/pacing.md): Rate limits per sender, domain and recipient, stacked over every send. Mail that has to wait sits in a queue you can read, release and reason about.
- [Nothing leaves at 3am](/features/sending-hours.md): Declare the hours mail may leave in, in the timezone that matters. Anything sent outside them waits in a queue you can read and goes out the minute the window opens.
- [Asked once to stop, and it stops](/features/suppressions.md): Bounces, complaints, unsubscribe clicks and replies asking you to stop all land on a list, and every send is checked against it before it leaves. One list per campaign, product or customer.
- [An email domain for every customer](/features/wildcard-domains.md): Connect *.yourapp.com once and give every customer their own email domain at signup — sending and receiving instantly, no DNS on their side.
- [A space for every customer](/features/spaces.md): Give every customer a space: their domains, their connected inboxes and every thread that went through them, kept apart — with one API key and one webhook endpoint on your side.
- [Email, from your terminal](/features/cli.md): Send and read email, run every API resource, forward webhooks to localhost without a tunnel, wait for an email in a test and check a domain's DNS — one binary, from a terminal, a script or an agent.
- [Give Claude an email address](/features/mcp.md): Give Claude, Cursor or any MCP client an inbox of its own. When it gets stuck, it emails whoever knows, gets on with the rest and picks the answer up when it lands.

## Use cases

- [Build the agent, not the inbox](/use-cases/ai-email-agent.md): Build your AI email agent on AI Inbx: reply categories, threading, clean reply text, attachments as Markdown, your users' own mailboxes and pacing, wired together in your code.
- [Build your outreach tool, not its email](/use-cases/cold-outreach.md): Build your cold outreach tool on AI Inbx: pacing, sending hours, scheduled follow-ups, reply categories and suppressions, wired together in your code.
- [Email for every customer, from one API key](/use-cases/multi-tenant-saas.md): Build email into your multi-tenant SaaS on AI Inbx: a subdomain per customer at sign-up, a space around each customer's mail, their own Gmail or Outlook, and pacing and opt-outs per customer, all behind one API key.

## Solutions

- [What you can build on AI Inbx](/solutions.md): Receiving, sending, connected Gmail and Outlook mailboxes and AI agents on AI Inbx: one page for each job, with the API calls that do it.
- [Receive email as one clean webhook](/solutions/inbound-email-api.md): Receive email in your app over an API. Point an MX record at AI Inbx or connect Gmail and Outlook, and every message arrives as a signed, parsed JSON webhook.
- [Just the reply, never the thread under it](/solutions/email-reply-parser.md): Parse every email reply down to what the sender wrote: quoted text and repeated signatures removed, answers typed inside the quote kept where they were.
- [Tell an auto-reply from a real answer](/solutions/auto-reply-detection.md): Tell an out-of-office, a ticket acknowledgement or a bounce from a real reply. Every inbound email arrives with a category, decided from headers and content.
- [Send email your users can answer](/solutions/send-email-api.md): Send email from your domain or your users' own Gmail and Outlook with one API call. Opt-outs and pacing are checked first, and replies land on the thread.
- [Send it later, and change your mind until then](/solutions/scheduled-email-api.md): Schedule an email up to 30 days ahead, then move or cancel it by id until its time comes. It is composed then, so suppressions and threads stay current.
- [Open tracking that tells people from machines](/solutions/email-open-tracking.md): Track email opens and clicks per domain or per send. Apple privacy prefetches and security scanner clicks arrive flagged as bots, each with its reason.
- [Tell every customer which DNS record is wrong](/solutions/spf-dkim-dmarc-check.md): Check a customer's SPF, DKIM and DMARC records over an API. Live lookups at their own nameservers name the record that is wrong and the change that fixes it.
