How to Read Email Threads

Read individual emails and full conversation threads, with options for body content, previews, and forensic headers.

Read the content of individual emails or view entire conversation threads grouped together.

Read a Specific Email

Once you have an email ID (from a search or listing), read its full content:

“Read that email from Sarah”

tool: read-email
params:
  id: "AAMkAGR..."

The response includes the subject, sender, recipients, date, and body content.

Control How Much Detail You See

LevelWhat you get
minimalSubject, sender, date — no body
standardSubject, sender, date, body up to 2,000 characters (default)
fullEverything — IDs, all recipients, body up to 40,000 characters

A cut body ends with a note naming the call that gets the rest: read-email with outputVerbosity: full, or for a body over 40,000 characters, export with target: "message", which writes the whole message to a file.

tool: read-email
params:
  id: "AAMkAGR..."
  outputVerbosity: "full"

Browse Conversation Threads

To see your inbox grouped by conversation instead of individual messages:

“Show me my recent email threads”

tool: search-emails
params:
  groupByConversation: true

This returns one entry per conversation thread, showing the most recent message in each.

Read an Entire Thread

Once you have a conversation ID, get all messages in the thread:

“Show me the full thread for that conversation”

tool: search-emails
params:
  conversationId: "AAQkAGR..."

Messages are returned in chronological order (oldest first) so you can follow the discussion. Up to 100 messages are returned; a longer thread ends with a “Conversation truncated at 100 messages” note, so export it with export target: "conversation" (up to 1000 messages) to get the rest.

Include Headers with Email Content

To see basic email headers alongside the body:

tool: read-email
params:
  id: "AAMkAGR..."
  includeHeaders: true

For forensic header analysis (DKIM, SPF, delivery chain), see Investigate Email Headers.

Tips

  • Search first with search-emails, then read with read-email using the returned ID
  • Use groupByConversation: true to get a bird’s-eye view of your inbox threads
  • Use outputVerbosity: "minimal" when you’re scanning multiple emails and only need subject lines
  • For a message or thread from a shared mailbox, pass the same sharedMailbox (alias email) to read-email and search-emails that you found it with, or the ID won’t be found — see Access Shared Mailboxes
