The Hidden Cost of Re-Reading Email Threads
Minutes lost re-reading every thread
When you return to a thread with 15+ messages, you spend several minutes re-reading to find the context you need. Workers already spend 28% of their workweek on email (McKinsey) — and a large portion of that is re-reading threads you've already seen, just to find a buried decision or condition.
Critical context buried mid-thread
The most important information in an email thread rarely appears in the first or last message. Decisions, caveats, and conditions get stated in message 7 of 15 — exactly where nobody looks. A Mailbird data analysis found that 35% of emails are never even opened, and even those that are opened tend to be skimmed rather than read carefully.
More people, more messages, less clarity
As teams grow and projects span more stakeholders, email threads get longer. More participants, more "reply all" chains, and more back-and-forth mean that threads spiral into unreadable walls of text. With global email traffic projected to reach 424 billion messages per day by 2028 (Radicati Group), the volume is only increasing — and so is the time spent untangling long conversations.

How Threadly Summarises Your Threads
Instead of re-reading every message, get an instant AI summary of what happened, what was decided, and what you need to do next.
Instant thread summaries
Threadly reads every message in a thread and produces a 2-3 sentence summary covering the key points, current status, and who said what — in seconds, not minutes.
Decision extraction
Every decision buried in the thread is pulled out and highlighted — approvals, commitments, and agreements — with source quotes so you can verify instantly.
Auto-updating summaries
When new messages arrive, the summary refreshes automatically. You always see the latest state of the conversation without manually re-reading anything.
Action item highlighting
Threadly identifies tasks, requests, and deadlines mentioned anywhere in the thread and surfaces them so nothing falls through the cracks.

Does the summary update when new emails arrive?
Yes. Threadly continuously monitors your threads and refreshes summaries whenever a new message is added. You always see the most up-to-date summary without having to re-read the entire chain.
