Let plain filters do the sorting you can describe in one line, such as newsletters or receipts. Use AI for what a filter cannot do: summarize long threads and draft first replies. Keep five or six labels. Review every draft before it goes out, and never let a tool delete or send on its own.
The short answer
- Triage: filters you write once move the predictable email out of your inbox.
- Labels: five or six, each tied to an action, not a topic.
- Summaries: AI reads the long threads and tells you what changed.
- Drafts: AI writes the first version. You edit and send.
Step 1: triage with rules you write once
Most email is predictable: receipts, newsletters, notifications, calendar replies. A filter handles these for free and never guesses.
Gmail. Filters can send email to a label, archive it, delete it, star it or forward it. You build one from a search, or from an email with Filter messages like these. Filters only act on new mail, and you can export them as a file to back them up (Gmail filters help).
Outlook. Rules can move email to folders, change its importance or delete it, based on the sender, subject and other conditions. New Outlook does not run rules on Gmail, Yahoo or iCloud accounts added to it. Set those up in the provider instead (Outlook rules help).
- Receipts and invoices from your billing tools: skip the inbox, label Receipts.
- Newsletters (search for unsubscribe): skip the inbox, label Read later.
- Notifications from your apps: skip the inbox, label Notifications.
- Calendar accepts with no message: archive.
- Your top clients, by domain: star, label Clients, never skip the inbox.
Check each filter's results once in the first week. A filter that hides a client email costs more than it saves.
Step 2: a short label set
Labels in Gmail are private to you, and you can create up to 5,000 of them (Gmail labels help). Do not. Every extra label is a decision.
Use labels for the action, not the topic:
- Reply today
- Waiting on others
- Clients
- Read later
- Receipts
AI tools can apply labels for you. Gemini in Gmail can label, archive and star email, but only after you confirm, and only with labels that already exist. You get 60 seconds to undo (Gemini in Gmail help). Superhuman, Shortwave and Fyxer also label incoming email automatically.
Step 3: summaries for the long threads
This is where AI saves real time. A 30-message thread becomes five lines.
- Gmail: Gemini summarizes threads into short points and finds details in old emails.
- Outlook: select Summary by Copilot at the top of a thread. The summary can include numbered citations that link to the message each point came from (Microsoft support).
Use the citations. Open the source message for anything with a date, a price or a promise.
Step 4: drafts you review
Let AI write the first version of routine replies: confirming a meeting, answering a common question, sending a document. Then edit and send yourself.
- Gmail's Suggested Replies can match your past tone, in English, on eligible plans (Google help).
- Copilot in Outlook drafts from a prompt, then lets you make it shorter, longer or change the tone before you insert it.
- Fyxer prepares drafts in your inbox before you open the email.
Drafts get better when the tool knows your rules. See make AI sound like you.

A daily routine that holds
- Open email twice a day at set times, not all day.
- Read the summaries first. Open only the threads that need you.
- Clear Reply today: edit the AI drafts and send.
- Move anything that needs more than two minutes to your task list.
- Check Waiting on others once a day and follow up where needed.
- Once a week, look at what the filters caught and fix one rule.

Nive is being built for this problem: you write how your business works and how you sound once, and it drafts emails in your voice for you to review and send. It does not sort or send your mail. Join the waitlist to get the demo first.
