How Mailercloud Tracks Transactional Email Opens

What is Email Open Tracking?

Email open tracking works by placing a tiny image, called a tracking pixel, in your HTML email. If the recipient has turned off image loading or is using plain text email, Mailercloud won't be able to track when the email is opened.

Enable Open Tracking for All Emails

To track when all your emails are opened, enable "Open Tracking" in the domain-level settings. Simply tick the box labeled "Track email opens."

Enable or Disable Open Tracking for Individual Emails

You can choose to enable or disable open tracking for each email, regardless of your general account settings. Use the mld-track-opens header in your email to do this:

• Set the mld-track-opens header to true to enable open tracking for a specific email, even if it's turned off for your account.

• Set the mld-track-opens header to false to disable open tracking for a specific email, even if it's enabled for your account.
