Email for law, finance & advisory
AI drafts.
You approve.
Always.
Blackstead reads your inbox and writes the reply — in your voice, with the right context. It never reaches a client, a regulator, or a counterparty until you say so.
No autosend. No exceptions. Every draft waits for a human.
Who it's for
Built for regulated professional services
Firms that can't afford a wrong word in writing. Blackstead drafts with the discipline those firms already work under — then gets out of the way of the decision that matters.
Drafts that respect privilege and matter context, so nothing goes out that reads like it skipped review.
Replies written with compliance language intact — suitable for the file, not just the inbox.
Client-specific tone held across every thread, even when a dozen engagements run at once.
How it works
Three steps. One that's non-negotiable.
Email arrives
Blackstead reads the thread, the sender, and the history before it does anything else.
→AI drafts a reply
In your voice, citing the right context, ready in seconds — sitting quietly in your inbox.
→You approve, always
Edit it, approve it, or discard it. Nothing leaves your inbox without your word.
Security & trust
Security you can put in an engagement letter
Built on the assumption that it will be asked about in a vendor review — not just a sales call.
Tenant isolation
Every firm's mail, drafts, and context sit in a separate, walled environment. No shared indexes, no cross-tenant retrieval.
No model training on your data
Client correspondence is never used to train or fine-tune any model — yours or anyone else's.
Encryption in transit & at rest
TLS on every connection, encrypted storage for every mailbox and draft, key-managed end to end.
Human-in-the-loop, by design
There is no autosend setting to find or disable. Approval is not a feature — it's the architecture.
