Zeigt Gmail Message-ID und Thread-ID der geöffneten E-Mail an und kopiert sie mit einem Klick. Gmail Message ID shows the identifiers of the email you currently have open in Gmail so you can copy them into tickets, logs, APIs, or support tools. When you open a conversation on mail.google.com, a small panel appears with: - Thread-ID from the Gmail URL - Message-ID (API / legacy) from Gmail's data-legacy-message-id - Message-ID (DOM) from Gmail's data-message-id If a thread contains several messages, you can switch between them in the panel. One click copies a single ID, all IDs, or a JSON object. The panel can be moved, collapsed, or hidden until the next reload. The extension does not send data to a server, does not require a sign-in, and does not modify the email. This extension does not show the RFC-822 Message-ID: header. For that value use Gmail: More → Show original. Single purpose: display and copy Gmail thread and message IDs for the open conversation.
