Read Receipt FAQs
How reliable are read receipts?
Boomerang read receipts are generally reliable, but we don't recommend that you rely on them as a guarantee. Read receipts are an indication that the email was likely read. Generally they work across different email clients and systems, but occasionally you may not receive a notification even if an email was read. And with our opt-out feature, the recipient may choose not to send the receipt.
What if I send an email to lots of people, can I tell who opened/read it or clicked the links?
I know the recipient opened my email. Why didn't I get a read receipt?
If you're sure your recipient opened your email, but you didn't receive a notification that it was opened, there are a few likely scenarios:
- There is a short delay between the time someone opens an email and that Boomerang sends the notification, to allow time for them to opt out if they choose.
- The recipient has chosen to opt out of giving a read receipt.
- The recipient's mail client has disabled the automatic loading of images, so Boomerang is unable to determine if the message was opened.
The number of opens seems too high. What could have caused this?
Self Opens Are Being Tracked
- Accessing the tracked message from Incognito or Private Browsing mode or web browser while not logged in to the manage page or the Outlook desktop client.
- Opening your tracked message from another PC or mobile device.
- Opening the tracked message from a different wireless network.
The email is being "opened" by security software
If the number is extremely high (e.g in the hundreds or thousands), it's most likely because the recipient's mailbox has software installed that scans emails, which can drive up the count. Boomerang is not able to distinguish between automated processes and human views.
