Frequently asked questions
Does tracking work with Gmail confidential mode?
The quick answer
Confidential or encrypted delivery can change the content and strip external images or links. Do not assume ordinary pixel tracking works; use the provider's actual supported flow and independent acknowledgment where needed.
Use a compatible message format
Check compose mode
Open the inbox compose menu and check whether Plain text mode is selected. An open-tracking image requires a rich-text/HTML message.
Choose the intended behavior
Use rich text if you want a tracking image and rewritten HTML links. Keep plain text and disable tracking for that message when plain text is your requirement.
Start a fresh message
After changing the format, open a new compose window and check the controls before sending.
Verify separately
Use a separate mailbox and check the event classification. Plain text cannot be made pixel-trackable by installing another browser extension.
