NOTE: If you are looking to install the Gmail Tabs Chrome extension, please read Getting Started with Gmail Tabs.

If you wish to combine two or more Gmail labels, you should filter email messages using Gmail search.
In the Gmail search bar, enter the labels you want to merge using a certain label operator (“label:”) in combination with a logical disjunction (“OR”) operator or logical conjunction (“AND”) operator that match multiple labels.
For example,

  • If you need to find all email messages that have one of two labels, use the “OR” operator as follows:
     (label:CLIENTS) OR (label:AGENTS)
  • If you need to find all email messages that have both labels, use the “AND” operator as follows:
     (label:CLIENTS) AND (label:AGENTS)
  • Do not forget to click the “Add to Tabs” icon in your Gmail, that your search will be saved as a tab.
