Smartlead’s reply tracking system is designed to securely sync lead responses while protecting your email accounts from spam flags. Replies may sometimes appear delayed or go to the Untracked Replies folder if they come from a different email address or start a new thread. Properly managing reply tracking, syncing settings, and account connections ensures you won’t miss critical communications.
Not seeing a reply you were expecting? Don’t worry — your lead’s message is almost always safe. In most cases, it’s just taking a little extra time to appear, or it’s waiting for you in the Untracked Replies section.
Here’s how to find them fast and fix the issue:
Built‑in Delay: Smartlead checks for replies every 30–60 minutes to keep your email accounts safe and avoid spam flags.
Different Email Thread: If a lead replies from another address or starts a new thread, it goes to Untracked Replies ( which is available from Pro and above plan) instead of your campaign thread.
Account or Sync Issues: Disconnected email accounts or incorrect settings can stop replies from syncing.
Give it up to 60 minutes before taking action — this is part of Smartlead’s safe‑sync process to avoid spam flags.
