How to Clean Up Your Gmail Inbox: A New Year Reset
To clean up your Gmail inbox, archive the backlog with one search, unsubscribe from what you never read, and filter what’s left so it skips the inbox. That takes about 30 minutes in Gmail itself.
Then hand the upkeep to Carly, which keeps every Gmail and Outlook inbox you have clean all year from one request.
The 30-minute Gmail reset, step by step
1. Archive the backlog with one search
- In the Gmail search bar, enter
in:inbox older_than:30d. - Check the Select box at the top left, above your messages.
- In the notification above the list, click Select all conversations that match this search.
- Click Archive.
Archiving deletes nothing: the mail stays in All Mail, turns up with in:archive, and returns if someone replies. Nervous about 30 days? Start with older_than:1y. Google also says an inbox over 250,000 emails can’t use the Default inbox type with its tabs, so a big archive fixes that too. More in how to archive emails in Gmail.
2. Delete old promotions and social mail
Run each search, select all matching conversations the same way, and click Delete:
category:promotions older_than:30dcategory:social older_than:30d
Archive category:updates older_than:1y instead, since Google files statements and confirmations there. Deleted mail stays in Trash for 30 days, then it’s gone for good. Full mechanics: how to mass delete emails in Gmail.
3. Unsubscribe in bulk with Manage subscriptions
- On the left of Gmail, click More, then Manage subscriptions. In the Android and iPhone apps, tap Menu, then Manage subscriptions.
- Each sender is listed with how many emails it sent you recently. Click Unsubscribe next to every one you no longer read.
- If a pop-up appears, choose Go to website to finish on the sender’s site, or Block instead.
Google says this removes you from every active mailing list from that sender, sends their new mail to Spam, and can take a few days to stick. The view is still rolling out, so it may not be in your account yet; the fallback is the Unsubscribe link next to the sender’s name at the top of any message. Blocking sends future mail to Spam but, Google notes, doesn’t take you off the list. To spot senders you stopped reading, search is:unread older_than:3m. More in how to unsubscribe from emails in Gmail.
4. Filter and label what’s left
- In the search box, click Show search options.
- Enter the sender or words, and click Search to check what matches.
- Click Create filter.
- Choose what happens: Skip the Inbox (Archive it), Apply the label, Star it or Delete it.
- Tick Also apply filter to matching conversations to sort past mail too, then click Create filter.
Three filters that pull their weight:
| Filter search | Action | |
|---|---|---|
| Receipts | subject:(receipt OR invoice OR "order confirmation") | Label “Receipts”, skip the inbox |
| Newsletters you keep | list:weekly@example.com | Label “Read later”, skip the inbox |
| Alerts | from:(noreply OR no-reply) | Label “Alerts”, skip the inbox |
Categories are Gmail’s automatic tabs (Primary, Social, Promotions, Updates, Forums), and Google says you can’t add your own. Labels are yours, and one email can carry several. See how to create filters in Gmail and how to create labels in Gmail.
Free up Gmail storage while you’re in there
A personal Google account comes with 15 GB, shared across Gmail, Google Drive and Google Photos. When it fills, Google says Gmail stops sending and receiving. Google’s own storage help suggests these searches for the heavy mail:
has:attachment larger:10Mfilename:pdf larger:5Molder_than:2y has:attachment
Delete what you don’t need, then empty Trash and Spam, which count against your quota until you do. Google says storage can take up to 48 to 72 hours to update after a big delete. Details in how the Gmail storage limit works.
Cleaning up Outlook too
Outlook has the same moves under different names: Sweep moves everything from a sender (future mail included) in new Outlook and on the web, Clean Up removes redundant replies in long threads, and a search like received:<01/01/2026 selects old mail in bulk. Our Outlook inbox cleanup guide has the full 30-minute version, and unsubscribing in Outlook covers the newsletter pile.
Keep every inbox clean all year with Carly
The reset is a one-time job, and with several accounts you run it in every one. Take Claire: a personal Gmail, a work Gmail and an Outlook account for her consulting clients. Instead of three cleanups in two apps, she connects all three to Carly once (Gmail, Outlook) and asks:
Archive every promotion older than 30 days in all my inboxes and unsubscribe me from anything I haven’t opened in three months.
Carly runs it across all of them at once, then handles the upkeep:
- Rules in plain English. “Label anything from my clients ‘Clients’ in all my inboxes.” Carly labels, moves and archives across Gmail and Outlook together, instead of one filter per account.
- Workflows that start on their own. Within minutes of mail arriving, a Carly workflow can file receipts and save the PDF to Google Drive or OneDrive, label client mail, trash promotions from senders you chose, or add a task to your to-do list when someone asks you for something.
- A daily brief across every inbox. One morning summary of what needs a reply, what’s waiting on someone else, and what can wait. Set it up in two sentences.
- Drafts and follow-ups. Carly drafts replies for you to approve and chases threads that went quiet.
- Agents you can CC. Build an AI agent with its own email address, CC it on a vendor thread, and it handles the back-and-forth.
Carly connects to thousands of apps, so the cleanup can feed Google Drive, OneDrive, Todoist, Slack or your CRM. It does not use your Google or Microsoft data to train AI models. Free Zapier-style workflows; AI agents from $35/month. Get started with Carly.

Frequently asked questions
How do I delete thousands of emails in Gmail at once?
Search for them (for example category:promotions older_than:1y), check the Select box above your messages, click Select all conversations that match this search, then click Delete. They move to Trash and are permanently deleted after 30 days.
Should I archive or delete old emails?
Archive anything you might search for again: receipts, statements, threads with real people. Delete promotions and social notifications. Archived mail still counts toward your 15 GB, so delete large attachments you no longer need.
Can Gemini clean up my Gmail inbox?
Yes, on an eligible Google Workspace or Google AI plan. Click Ask Gemini at the top right of Gmail and ask it to archive, delete, label, star or mark mail as read. Nothing happens until you confirm, and you get 60 seconds to undo. Google says a request matching more than 10,000 threads is not processed, and unsubscribing is not on its documented list. Gemini works in the Gmail account you have open; Carly works across all your Gmail and Outlook inboxes and keeps going on its own. More on Gemini in Gmail.
How often should I clean up my Gmail inbox?
Run the full reset once a year; January is a natural point. In between, a five-minute pass on Promotions each week keeps it down, or a Carly workflow does it daily across every inbox.

See what people say
"Before Carly, I relied on a Calendly link, but the whole process felt impersonal and not very professional. Carly changed that by handling all the back-and-forth, so I'm no longer stuck in endless email threads trying to line up schedules.
Now Carly reaches out to candidates, shares my real-time availability, lets them pick a slot, then sends a Zoom link and drops it straight into my calendar. She sends reminders to both of us before each call, which has significantly reduced no-shows and last-minute confusion.
On top of scheduling, Carly acts like a full executive assistant, sending me my schedule the night before so I can prepare for each call. It reminds me of the old x.ai assistant, but Carly is noticeably smarter, faster, and better suited to my healthcare recruitment business."
