General troubleshooting

The recipient's mail service may block tracking

The quick answer

Some clients block remote images or serve cached/proxied requests. A missing open signal can be expected. A qualifying click or connected-mailbox reply can provide separate evidence of engagement.

In Latest activity, search for Atlas. Open Maya's message to inspect the individual report.

Check the recipient and timeline: one likely-human open, no clicks. You can download a certificate for this message.

Now open Elena's privacy-protected event. The privacy fetch stays separate from likely-human engagement.

Open Email tracking and change the report period to seven days. The report updates to the selected window.

Read open activity correctly

  1. Find the tracked message

    Open Email tracking and search by subject or recipient. Choose a date range that includes the send.

  2. Inspect the event classification

    Likely-human evidence is separate from privacy-protected image fetches, security scans, sender/self activity, and unknown requests.

  3. Check delivery scope

    A normal email with multiple recipients shares a tracker. Use individualized campaign deliveries when you need recipient-level attribution.

  4. Use other evidence

    A likely-human click may imply access when images are blocked. Replies come from a connected mailbox and are separate evidence.
