Gmail Labeler

Label and filter Gmail threads using basic RegEx against the email body or headers.

Configuration

Filters Options

var filters = [
  // star emails deliveredto user@domain.com
  { name: 'user emails', match: /deliveredto:user@domain.com/, star: true },
  
  // organize by list name
  { match: /(?:List-ID:\s(.+?)\s<)/, archive: true },

  // label all emails with "bank" in the subject as "finance" and mark as read
  { name: 'finance', subject: 'bank', markRead: true },
];

• name - The label name to apply when matched. This can also be nested by adding slashes folder/name. If no name is set, it will use the first RegEx selector result (.+?)
• match - The RegEx to match against. This searches the entire raw contents of the email, including the header. Include a RegEx selector to return dynamic label names (.+?)
• subject - Helper to search the subject for text
• archive - true/false to archive the matching emails
• star - true/false to star the matching emails
• markRead - true/false to mark the matching emails as read

From

var from = [
  "from:email@domain.com",
  "list:subscription.domain.com"

This can be any combination of Gmail filters to apply the labels against.
