Email open tracking is currently not functioning as expected for certain email providers.

[DharmikJagodana]

Example
When sending emails to Gmail clients, the images do not load, and the system registers an "opened" event even when the user is in the inbox screen and has not yet opened the email.

Expected Behavior
The email open tracking should accurately detect when an email is opened, and the image rendering should work seamlessly across various email providers.

Steps to Reproduce

1. Send an email to a Gmail account with email open tracking enabled.
2. Observe that the images do not load properly.
3. Check the tracking system, which erroneously registers an "opened" event even before the email is opened.

Additional Information

• This issue is not limited to Gmail and may affect other email providers.

Gmail (and some others providers) treats images and html contents to indeed prevent us to track their user. If you have any idea to workaround, send a PR ;)
