Mark Gmail thread as read

Automatically mark Gmail thread as read on mail.google.com. Mark a Gmail thread as read by its hex threadId, in the chosen Google account, wherever the thread is filed. Returns read, threadId and already_read. Safe to repeat: a thread that is already read returns already_read:true without changing anything. Success is reported only once Gmail has saved the change and a fresh read shows the thread read. An unknown or malformed id is refused without changing anything.

Input

threadId required

Hex legacy thread id (as returned by search_emails).

account optional

The Google account whose thread this is: its email address, or Gmail's account number in this browser (e.g. "2"). The run fails if that account is not signed in. Omit for the first signed-in account (u/0).

Output

read required
threadId required
already_read optional

true = the thread was already read; nothing was clicked.

Search the signed-in Gmail with the native query syntax (from:, to:, subject:, has:attachment, after:/before:, labels…) and return matching threads: threadId (feed it to get_thread / reply_to_email), sender, senderEmail, subject, snippet, date, unread, starred, hasAttachment.
