KoltrixA founder's weekly email rhythm with Claude and Koltrix
A Monday brief, daily triage, a promises sweep, a finance tidy and a Friday close-the-loop, built from what a connected assistant can really do with your mail.

A founder's inbox is several inboxes wearing one name. Customers, prospects, vendors, investors, candidates and the occasional stranger all land in the same list, and each needs a different kind of attention.
Connecting an assistant to your Koltrix workspace does not change who you answer. It changes how much time the finding, sorting and first drafting takes. This post lays out a weekly rhythm for using Claude or ChatGPT with your mail, built from the things an assistant can really do with Koltrix: search, read, organize and draft. It leaves out heroics.
Set it up so you trust it
Before the weekly rhythm, three settings decisions make everything else safer.
- Sending stays off. By default, an assistant can read, search, organize and draft. Sending is off until an owner or admin turns it on, and then you opt in and the assistant has to show you each message and get your yes. As the founder you are probably the admin who would turn it on. Do not, at first. Drafts you send yourself are already a large time saving.
- Connect the right workspace. A connection belongs to one workspace. If you run more than one, connect again for each and choose it on the approval page.
- Know what is read. Mail the assistant reads goes to its provider, such as Anthropic or OpenAI, under their terms. If a mailbox holds things you would not paste into a chat, such as a sensitive legal thread, keep those threads out of your assistant sessions. An assistant has all the access you have, so you cannot connect it to only part of your mail; the control is what you ask it to look at. What your AI provider sees explains it.
Connect Claude or connect ChatGPT first if you have not.
The weekly rhythm
| Day | Block | What the assistant does | What you do |
|---|---|---|---|
| Monday | Weekly brief | Looks back seven days, lists what waits on you | Decide the week's reply order |
| Daily | Triage | Maps unread, drafts routine replies | Read, edit, send |
| Wednesday | Promises sweep | Lists what you promised and when | Chase or renegotiate |
| Thursday | Vendor and finance tidy | Labels and archives receipts and invoices | Skim, spot-check |
| Friday | Close the loop | Lists conversations still waiting, drafts nudges | Send or let go |
Each block is a saved prompt. Here they are.
Monday: the weekly brief
Make my weekly brief for the last seven days. Count conversations I replied to versus ones still waiting. List the five oldest waiting on me, one line each with who and what. List anything where I promised a date that has passed. Under 200 words. Change nothing.
The point is a decision, not a summary: which five conversations get your first hour. For the daily version of the same idea, see a daily inbox brief.
Daily: triage in ten minutes
Look at Primary, unread. Which conversations need a reply from me today? One line each. Then draft replies to the two easiest, brief and friendly, and leave them in Drafts.
Primary is where people writing to you land, so starting there keeps strangers out of your attention. The assistant reads the threads, and drafts land in your Drafts folder with links that open them in Koltrix. Inbox triage with Claude has the three-pass method.
Wednesday: the promises sweep
Founders make promises in email all day and forget half of them. This prompt is the highest-value one in the set:
Search my sent mail from the last two weeks for messages where I committed to something: a date, a deliverable, an intro. List customer, promise and date in a table. Mark any whose date has passed.
Sent mail is a folder the assistant can search, and it can read each thread to check what you actually said. Expect some false positives and some misses. The result is a list to review, not a ledger. Verify each against the thread before you act, and do not assume a clean list means nothing was missed.
Thursday: vendor and finance tidy
Find receipts and invoices from the last week. List sender and subject, nothing changed. Then, after I confirm, label them "Finance" and archive them.
Two prompts, with a preview in between, which is the cheapest safeguard available. Everything the assistant did can be undone from Koltrix. If your receipts always look the same, an auto-label rule will do this without you. The assistant is for the irregular ones. Organizing your inbox by chat has the safe cleanup pattern.
Friday: close the loop
List conversations where I sent the last message more than five days ago and have not had a reply. For each, draft a two-sentence nudge. Do not send anything.
You get a short pile of drafts, and for each one a decision: nudge, wait, or drop. The assistant never sends them. You do.
Different people, different tone
A founder writes to customers, investors and candidates in different registers, and an assistant does not know which is which until you say.
- Customers: direct, warm, specific. "Match my last three replies to Dana."
- Investors: short, factual, no hype. Give the numbers yourself and tell the assistant not to add any.
- Candidates: kind and clear about timing. Do not let it promise anything about decisions.
- Vendors: brief and businesslike.
Keep the voice notes in a saved instruction. And on anything with numbers, tell the assistant "use only the figures I give you." A drafted sentence with an invented metric in an investor update is the kind of mistake that is hard to take back.
What stays with you
An assistant is a fast pair of hands, not a delegate with authority.
- Anything with a number you have not given it.
- Pricing, discounts, refunds and contracts. The assistant can find the thread and summarize it. You write the answer.
- Hard conversations. Terminations, disputes, apologies after a failure.
- First contact with someone important. You are the brand.
- Anything legal or compliance-related. An assistant is not a lawyer, and this post is not advice.
Guardrails that cost nothing
- Read drafts before sending. Every one, at the start.
- Keep sending off until you have used drafting for a few weeks and know what you would delegate.
- Review your connections now and then. Old ones lapse after 30 days of inactivity, and you can revoke any of them in Koltrix at once. Reviewing and revoking AI app connections suggests a monthly check.
- Read the odd ones yourself. Email can contain text written to manipulate an AI, and Koltrix labels mail content as untrusted and keeps the toolset narrow, but a summary that says an email wants something unusual from you is a reason to open the email.
A small experiment
If you are unsure whether this is worth it, run a two-week test and keep your own notes. Count nothing fancy: how long does your Monday brief take with and without it, and how many drafts did you send with only light edits? You will have a real answer from your own mail instead of anyone's claim.
Key takeaways
- Keep sending off at first, connect the right workspace, and know that mail the assistant reads goes to its provider.
- Build a weekly rhythm from saved prompts: a Monday brief, daily triage, a Wednesday promises sweep, a Thursday tidy and a Friday close-the-loop.
- Use the assistant for finding, sorting and first drafts, and keep numbers, pricing, hard conversations and legal matters yourself.
- Preview before bulk actions, read drafts before sending, and review connections monthly.
