Priority rules in Gmail and Outlook come down to the same four filters: a short list of people who always come first, mail addressed only to you, mailing lists that can wait, and everything else. Gmail builds them with filters, Outlook with rules, and neither tool can see the other. This guide gives the exact steps for both, one rule set you can copy, and the three places where rules stop working.
The rule set to copy
Four rules cover most of what a founder needs, and each one uses only what the tool can match without guessing. The table lists the condition for each side. Gmail's search operators come from Google's operator list, opened on October 21, 2026.
| Feature | Gmail filter | Outlook rule |
|---|---|---|
| 1. People who come first | from:amy@example.com, action: star, label VIP | Condition: from the sender, action: flag for follow up or move to a VIP folder |
| 2. Mail addressed to you | to:me, action: label Direct | Condition: sent only to me, action: move to a Direct folder |
| 3. Lists that can wait | list:info@example.com, action: label Later, archive | Condition: subject or sender contains the list, action: move to a Later folder |
| 4. Attachments from clients | from:client has:attachment, action: star | Condition: from the client and has attachment, action: flag |
The Gmail operators behind the table are from:, to:, cc:, list: and has:attachment. Google describes list: as finding emails from a mailing list and - as excluding emails from your search criteria. Outlook's rules page gives "Subject contains" and a move to a folder as examples, and a template that flags messages from a specific sender for follow up.
Gmail: create a priority filter in five steps
A Gmail filter is a saved search plus an action. Google's page lists the steps below, and says filters can send mail to a label, archive, delete, star or forward it.
- Open Gmail and click the Show search options icon in the search box.
- Enter the criteria, for example
from:amy@example.com, and click Search to check what it finds. - At the bottom of the search window, click Create filter.
- Choose the action: for the first rule, star it and apply your VIP label.
- Click Create filter again to save it. A faster start: select a message, open More and click Filter messages like these.
When we checked the page on October 21, 2026, it listed no marking as important and no skip the inbox action, and it states no maximum number of filters. It only says that for forwarding filters, only new messages are affected, and that replies to filtered messages are filtered only if they match the same criteria. Gmail's own Important markers work separately, as we explain in how an AI decides which emails are important.
Outlook: create a priority rule in new, classic and web
Every Outlook rule needs a name, a condition and an action, and the steps differ by version. Microsoft's page describes three paths.
- New Outlook: right-click a message, open Rules, create a rule, pick a destination folder and confirm. For more control open the full rule settings, then save.
- Classic Outlook: right-click a message, open Rules and choose Create Rule, or go to File, Manage Rules & Alerts and build one from a template.
- Outlook on the web and Outlook.com: open Settings, go to Mail, then Rules, add a rule, name it and set conditions and actions. Exceptions are optional.
On work or school accounts Microsoft says a rule can notify you when it moves an email. The page does not list a categorize action or a general alert action, so the Outlook column above sticks to move and flag. For the Teams side of the same problem, see how to keep Outlook and Teams from burying a deadline.
Where rules stop working
Rules fail in three places: across tools, on accounts from another provider, and on messages that match no rule. The first two are documented, the third is simply how rules work.
First, Microsoft's page says new Outlook currently does not support rules for managing third party accounts like Gmail, Yahoo and iCloud, so a Gmail address inside Outlook needs its filters in Gmail. Second, some classic rules cannot be processed by new Outlook because they are client side rules, and a rule with a custom action runs only on the computer where it is installed and only when Outlook is running. Third, a rule only knows what you told it in advance. A new client who writes once, from an address no rule lists, lands in the same pile as a newsletter. Our triage routine for 200 messages a day covers what to do by hand in that case.
When one rule set per account is not enough
If you read Gmail, Outlook and Slack, you maintain one rule set in each and still decide in three places. Nolario is our product, so weigh this pick accordingly. We suggest it here because it connects Gmail and Outlook and scores every message from 0 to 100 in one list, using the sender, a VIP list you keep, whether the message is addressed to you and whether it contains an ask, so a new sender with a direct question does not need a rule to rank high. You still keep rules as the cheap first layer.
The limits are plain. Nolario ranks and drafts but does not file, archive or send anything for you, it is a desktop web app, and access is by waitlist. It is also not a team mailbox. See the integrations and pricing pages for what connects today.
