AI assist

Nothing here publishes or sends. A suggested subject fills the field for you to keep or change; a draft lands in the editor and is saved only when you save it; a diagnosis is a read of what already happened.

Draft with AI sits in the Inbox, in the panel that opens when you reply to a conversation. It reads the message you are answering and the few turns before it, writes a short reply into the editor, and stops there — you edit it and press Send yourself, and nothing is sent until you do. It writes no sign-off, because your mailbox's signature is added under it, and it answers only from what is in the conversation: it will ask a question rather than invent a price, a date or a promise. One draft is one credit, the same credits the rest of this page spends, and there is no separate charge for it. It is in the dashboard only — there is no API call for it.

The same three helpers are POST /ai/subject-lines, POST /ai/draft and POST /emails/{email_id}/diagnose, and in the Node and Python clients ai.subjectLines, ai.draft and emails.diagnose. They take a full_access key or an OAuth token with ai:use, and they answer to the same switch, the same credits and the same rate limit as the dashboard. None of them touches a send: nothing is saved or sent, and there is no AI field on POST /emails. The AI reference has each call and the order the refusals come in.

Requests go to Anthropic's API. The content you ask about is sent to generate the answer, it is not used to train models, and it is not kept by us beyond what is described below.

• Subject lines and drafts send the template content on your screen — the subject, the HTML and the plain text — plus the brief you typed.
• An Inbox reply draft sends the conversation: the subject, the message you are answering and up to four earlier messages, each cut to a length we cap. Every address in them is removed first, senders’ included — only display names travel.
• A diagnosis sends the email's subject, your sending domain and its verification status, each recipient's domain with its delivery status and bounce classification, the event timeline, the risk flags and the message size.
• A recipient's address is never sent. Only the part after the @ travels, and every free-text field — a bounce's diagnostic code, an event's message, the subject — has addresses stripped out of it first.
• A message body is never sent for a diagnosis, and neither are headers, attachments or anything belonging to another team.

We store what the request cost — the kind, the model, token counts, how long it took and whether it succeeded — and, for a diagnosis only, the answer itself. We do not store the prompt or the completion text of anything else. These records are kept for 90 days.

Your plan sets the monthly credits, and Settings → Team shows how many are left. A request that fails on our side or the model's costs nothing: only an accepted answer spends a credit.

A diagnosis is stored against the email, so reopening it costs nothing. Asking again after new events have arrived is a new question about a changed message, and spends a credit.

An email that failed on our mail servers' side is not sent to the model. The answer gives the recorded reason and what you can do, marked cause: provider_failure, and costs nothing.

The help drawer in the dashboard has its own assistant. It answers questions about Rasket and nothing else. Ask it about something else and it says so in one sentence.

• What it sees: your question, the dashboard page you asked from, and our public documentation.
• What it can look up about your account: your domains and the DNS records they need, your plan and this period’s usage, recent bounces and failures by recipient domain, your API keys by name and permission, your webhook endpoints and their health, and whether receiving is set up. It looks these up only to answer you, it can never change any of them, and it checks at most three of them per answer.
• What it never sees: recipient addresses, message bodies, API key values, webhook signing secrets, card details, and anything belonging to another team. Addresses in your question are removed before it is sent, and so is any address in what it looks up — it is told the recipient domain and never the address.
• Who can use it: everyone on the team. It does not need the AI assist switch and costs no credits.

Messages are sent to a model provider to answer them and are never used to train models. We keep the conversation for 90 days so we can improve the answers.

A model writes plausible text, not verified fact. A subject line is a suggestion, a draft is a starting point, a diagnosis is a reading of the same events you can see on the page yourself, and an Inbox reply is words for you to check before you put your name to them. Nothing it produces is applied to anything until you apply it.
