Common Questions About Email Tracking

How do I know if email tracking is working?

After sending a tracked email, you will see it in your TrackMailBox dashboard with a "Sent" status. Once opened, the status changes to "Opened" with a timestamp. You will also receive a desktop notification if enabled.

Can I track emails I already sent?

No, tracking must be enabled before sending. The tracking pixel is embedded when you click send. You cannot add tracking to emails that have already been sent.

Do recipients know I'm tracking emails?

With TrackMailBox, recipients cannot tell you are tracking. Unlike other tools that add signatures, we remain completely invisible. However, tech-savvy users might check email headers or disable images.

Can I track emails sent to multiple recipients?

Yes, TrackMailBox tracks emails sent to multiple recipients. You will see individual open data for each recipient, including who opened it and when.

Is there a limit to how many emails I can track?

No limits. TrackMailBox offers unlimited email tracking completely free. Track 10 emails or 10,000 with no restrictions.
