How to Use Gemini in Gmail Step by Step: Summaries, Drafts and Inbox Questions

You come back to 80 unread emails and one thread so long that nobody remembers what was decided. Gemini in Gmail will not clear that inbox for you, but it can make the reading, drafting and hunting much shorter — if you know where it lives and how to check its work.
Key points
- Open Gemini from “Ask Gemini” at the top right of Gmail — a side panel, on eligible accounts only.
- Use it to summarise long threads, draft and refine emails, and answer inbox questions such as flight times and package tracking.
- Nothing is archived, deleted or labelled until you confirm it, with 60 seconds to undo — always check its work against the original.
Before you start, check whether you actually have it
If the button is missing, it is usually your plan.
Gemini in Gmail requires an eligible Google Workspace or Google AI plan. It is also available through Google Workspace Experiments, a trusted tester programme for personal accounts. If you do not see it, your plan or account type is the likely reason — no Gmail setting will switch it on. This guide sits inside our wider explainer on AI email assistants in Gmail and Outlook.
On eligible accounts, walkthroughs also describe two shortcuts: “Help me write” in the compose window, and a “Summarise this email” control at the top of a long thread.
Step 1: Open the Ask Gemini panel first
Everything in this guide starts from one side panel on the right.
On a computer, open Gmail and, at the top right, click “Ask Gemini”. The side panel opens on the right. Pick a suggested prompt, or write your own, then click Submit. No separate app, no new tab. Vague asks get vague answers.
Step 2: Summarise a long thread before you reply to it
A good summary turns twenty messages into the few points that matter.
Open the thread that has been draining you, then ask Gemini to synthesise it into concise bullet points. Google’s own examples show the range:
| What you type | What you get |
|---|---|
| “Create a list of action items for me based on this email” | Tasks and decisions pulled from the thread |
| “Explain this email to me like I’m 5 years old” | A plain-language version of the thread |
Then skim the original for anything off — a name, a date, a commitment. That check is the difference between using the tool well and simply trusting it.
Step 3: Let Gemini suggest a reply, then make it yours
A suggested reply is a starting draft, not a message you have sent.
At the bottom of the side panel, click “Suggest a reply”, or ask Gemini to draft a reply. It works best after a summary. Edit the tone, fix any guessed detail, and only then send it yourself. A reply that sounds almost right is still wrong if its date or promise is wrong.
Step 4: Draft a brand-new email and refine the tone
Staring at a blank compose window is optional now; editing is not.
Ask Gemini to draft from a short brief. Google’s example is: “Draft an email to Kevin summarizing our progress on Project Clover” — use it as a template: who it is to, what it must cover. Written something blunt? Ask it to refine it, as in Google’s example: “Refine this chat message I am sending to Lori: ‘We are good to start Project Clover.’ Make sure it’s professional and concise.” Specific instructions beat long explanations. Our checklist for checking AI answers before you trust them applies to drafts too.
Step 5: Ask your inbox questions instead of searching it
Your inbox already knows your flight time — Gemini can go and find it.
This feature replaces the miserable scroll-and-search routine. Ask things like “When is my package arriving?” or “What’s my first meeting tomorrow?” Gemini can surface flight times, package tracking and reservations from previous emails, and propose meeting times from your primary Google Calendar. To point a question at the calendar, start it with “@Calendar”. For scheduling it can only see your primary calendar — secondary calendars are invisible to it.
Step 6: Organise safely, because nothing moves without your say-so
Gemini tidies only after you explicitly confirm.
Gemini can archive, delete, label, mark as read or unread, and star — but emails are never actioned until you confirm. Afterwards you have 60 seconds to undo. Two rules: you can only add labels that already exist, so create the label first; and deleted mail sits in Trash, permanently deleted after 30 days. Start with one small batch — last month’s newsletters — until the rhythm feels natural.
Beyond email: Docs, Drive and tasks from the same panel
The panel reaches further than Gmail — review before confirming.
From the same panel, Gemini can generate Docs, Sheets, Slides and images, and help manage Drive files and tasks. Google’s caution is the right one: review suggested file actions before confirming them, just as with email.
When Gemini gets it wrong, these are the limits to know
Helpful, still learning, and no substitute for the original.
Google is plain about this: Gemini is constantly learning, may not support every request, and its suggestions do not represent Google’s views. Requests matching more than 10,000 threads are not processed, and it cannot mark multiple emails as spam. If a summary or draft matters, check it against the original before you act or send.
What this means
The job changes from reading everything to reviewing a prepared version of it.
For most of us, email has never really been about writing. It has been about the draining work around it: reopening a thread for the fourth time to find one date, scrolling past read messages to reach the unread one, holding three half-decisions in your head while you compose a reply. That is the part that leaves people tired before they have done anything difficult. Gemini in Gmail goes straight at that layer, and that, in our view, is why it matters more than the flashier tricks.
The shift is subtle but real. Instead of reading everything, you review a prepared version: a summary you can challenge, a draft you can correct, an answer pulled from mail you forgot you had. The skill moves with it. Being good at email used to mean being fast and thorough. Increasingly it means briefing well — a clear question, not a hopeful one — and checking well, spotting the confident line the original thread never quite said. Those habits suit busy people far better than heroic inbox stamina.
The relief is easy to picture. The parent checking mail between school runs, the freelancer whose clients all write at once on a Monday, the manager returning from leave — ten minutes of reviewing beats an hour of excavating. Fewer replies postponed until they become apologies. Email dread is a real tax, and this lowers it.
The risk sits in the same place. A summary trusted too quickly can drop the one caveat that mattered, and a polished draft can make a wrong promise sound professional. The answer is not to avoid the tool — keep the human job, delegate the heavy lifting. Let Gemini read, draft and search first. Keep deciding, checking and sending for yourself. Used that way, it gives your judgement time to work. Choosing tools more broadly? Our guide to the best AI tools for everyday work, by task puts this one in context.
Bottom line
Start with summaries, keep the checking habit, and let it earn the bigger jobs.
Our verdict: begin with summaries and inbox questions, where checking is easy, and let Gemini draft once that feels safe. On an eligible account, this is one of the most practical AI features you already have — no new app, just clear asks and critical reading.
