Postra connects to your existing inbox and turns email into an intelligent workspace — summaries, reply drafts, follow-ups, tasks, and smart search without changing your email provider.
Works with Gmail, Outlook, Microsoft 365, Google Workspace, IMAP, and custom SMTP.
Hi Sarah — reviewed the redlines. The indemnity clause works on our side; I've flagged section 4.2 for a small wording change and can sign today. Sending the updated copy shortly.
Connects to the mailbox you already use
Your inbox contains tasks, clients, deadlines, invoices, meetings, context, and forgotten follow-ups. Postra helps you understand what matters without manually reading every thread.
Hundreds of conversations, each with hidden asks. The important ones blur into the noise.
A reply slips, a lead goes cold, an invoice waits. The cost of forgetting is quietly enormous.
Reading, triaging, and re-reading drains hours. Your focus is spent before real work begins.
See what changed since you last checked.
Draft thoughtful replies in your tone.
Never lose a client, lead, or important thread.
Extract todos, deadlines, and owners automatically.
Ask your mailbox questions in natural language.
Detect urgent, high-signal emails automatically.
Link Gmail, Outlook, or any IMAP mailbox with secure OAuth.
Postra indexes and understands your mailbox and context.
AI summarizes, organizes, and drafts replies for you.
Send through your own connected provider — always.
Postra does not host your mailbox or send email through its own mail servers. Sending happens through your connected provider.
Postra is designed as a layer on top of your existing mailbox, not a replacement for your email provider.
Connect with provider-approved OAuth wherever available.
Tokens and credentials are encrypted at rest and in transit.
Postra never operates an outbound mail relay of its own.
Nothing is sent without your review and your connected account.
Disconnect in one click and revoke access whenever you want.
Your mailbox is processed to serve you — never to train public models.
