Gmail message ID finder

Download extension

Adds a 'Copy message ID' button to Gmail messages which generates a search term that you can later use to get back to your message.This extension allows you to easily generate unique search terms for your Gmail messages, so you can find them later.

After installation, you will see a 'Copy message ID' item in the menu for each email.
When you click the item, a unique search term (based on the email identifier of the message) will be copied to your clipboard.
Save that ID somewhere in your notes or wherever the message is relevant (for instance with project documentation, a group chat with other people that got the message or a project invoice) and simply paste it back into the Gmail search bar to quickly find that one message.
