What the Gmail Agent does

Six everyday things that save you time. All work with your real Gmail.

Drafts replies for you

Every new email gets a draft ready in your inbox. It sounds like you. You read it, change anything you want, and hit send.

Sorts your inbox

New mail gets a label the moment it arrives: important, reply needed, just FYI, or newsletter. You see what matters first.

Sums up long emails

Before you open a long thread, you get a short summary and what the sender actually wants from you.

Reminds you to follow up

If someone went quiet on an email you sent, the agent notices and writes a polite follow-up for you.

Uses your own info

Connect your docs from Notion, Drive, or a help center. Replies use your real info, not guesses.

You are still in charge

Nothing sends by itself. Every reply waits for you to approve. You can disconnect Gmail any time in one click.

Three steps, two minutes

Connect. Feed it context. Open Gmail and start reviewing drafts.

Step 1

Connect Gmail

One-click OAuth. Read & draft scopes only. You can revoke access at any time from your Google account.

Step 2

Add your context

Connect Notion, Drive, or paste in help docs. The agent learns your voice from 5–10 past replies.

Step 3

Open Gmail. Review. Send.

Every new thread gets a draft waiting for you. You ship replies in seconds, not minutes.

Powerful workflows, out of the box

Triggered by new mail, schedules, or a single click. All wired into the agent template.

Auto-draft when mail arrivesNew email

A customer writes in. The agent reads the thread, pulls context, and leaves a draft in Gmail.

You are always the sender

Control what the agent can touch. Revoke access whenever. Sleep easy.

Drafts-only by default

Send permission is disabled out of the box. You opt in per label if you ever want auto-send.

Per-label rules

Decide what gets drafted, what gets escalated, what gets ignored. Legal and refunds always flag for humans.

Pause in one click

Toggle the agent off from the dashboard. Drafts stop immediately, nothing queued.

Revoke anytime

Disconnect Gmail to revoke OAuth and delete stored context. No residual access.

Questions, answered

No. The Gmail Agent creates drafts in your inbox. Nothing goes out unless you explicitly enable auto-send for a specific label.

Read and draft scopes. We never request send or delete permissions by default. You can revoke access from your Google account at any time.

Paste 5–10 of your past replies into the agent settings. It learns your voice and uses it when drafting.

Yes. Connect Notion, Google Drive, or your help center as knowledge sources. Replies will reference your actual documentation.

Fully supported. Team plans include shared inboxes, admin controls, and audit logs.

You can start for free — no credit card needed. The Free plan includes a usage allowance that refills every 5 hours, so you can try the Gmail Agent on real email. Paid plans unlock more usage, every AI model, and team features. See the pricing page for details.
