License: MIT node workflow

Ukko is a code name for a google apps script runs on google servers. It can get emails in your inbox or use search, looping over email threads and assigning labels based on the email metadata. It's intended be setup via google drive and have time driven trigger.

Using on google drive

  1. Access your google drive, click New and select "Google Apps Script".

NOTE:

  • Missing labels are created automatically.
  • Feel free to delete labels in gmail at any time, they won't be recreated until matching email is processed by Ukko.
  • Labels separated by "/" are nested.
  • Threads are assigned all labels in the nested chain, for label "lists/my-list/company", following are assigned:
    • "lists"
    • "lists/my-list"
    • "lists/my-list/company"
  • Labelled threads are shown at all nesting levels.

NOTE: To automatically "archive" the thread after labels are applied, uncomment following line in modules/ukko.js :

if (labels.length) { inboxThread.moveToArchive() }

Expect similar output when executing the script in google apps script "execution log":

from:[email protected] labels:lists/planet-list

Extending label rules

Modify getLabels function of modules/ukko.js to add your own logic for setting up labels. Few example rules are included with ukko, feel free to change to suit your needs.

Create "catch all" filters for given domain:

// process @github.com
if (messageFrom.includes('@github.com')) {
 labels.push('github')
}

Here's an sample to extract GitLab project name from header named X-GitLab-Project and assign label gitlab/projectname:

// process gitlab notifications
if (message.getHeader('X-GitLab-Project')) {
 labels.push(`gitlab/${message.getHeader('X-GitLab-Project')}`)
}

Here's a sample to assign label from the value of List-Id header, in this example extra label is added where sender domain doesn't match mydomain:

// process mailing lists
if (message.getHeader('List-Id')) {
 // extract my-list from 'My List <my-list.example.com>'
 const listIDshort = getReMatch('listid', message.getHeader('List-Id'))
 let listLabel = 'lists/' + listIDshort
 if (messageFromDomain !== 'mydomain') {
   listLabel += `/${messageFromDomain}`
 }
 labels.push(listLabel)
}
