Most of these emails are only useful if I read them on the same day, but if they stay in the inbox, they become noise and waste time the next day. Still, I do not want to unsubscribe from them as from time to time they do bring something interesting - that’s also the initial reason I subscribed to them.

Gmail filters, unfortunately, don’t offer a way to automatically handle emails based on their age. You cannot make a rule, "do that and that for emails of 3 days ago”.

To solve this issue, ChatGPT helped me build a small automation that is shared below:

✅ What the script does

  1. Automatically archives yesterday’s emails according to customizable rules
    (for example, you can include/exclude messages based on whether they are starred or contain certain keywords).

  2. Sends you a daily summary at 8 AM showing everything that was archived, so you can quickly check if anything important was removed.

  3. Lets you manage all rules in a Google Sheet, so you never have to edit the script itself.

How to set it up:

  1. Open a new Google Sheet, give it a name like “Newsletters Filter Rules”

  2. Rename a default Sheet into “Rules” - you whatever you want

  3. Set up parameters in this Sheet

    So it will look like this:

This spereadsheet above has following columns, and they have to be exactly in this order and with the same names:
Enabled - if the Rule is active
RuleName - just a name, whatever you put
Sender - email of the sender
SubjectWords - if you put something here, than rule is applied only if it find the words in the subject
StarredHandling - if Exclude - then exclude those that starred, Include - include them

4. Now paste the code: In your google spreadsheet go to Extensions→App Script and paste the code below:

(here how it looks)
