Tracking doesn't show the email was opened

You may know that an email was opened (perhaps because you received a reply), but your Live Feed or the lightning bolts in Gmail don't indicate that the email was opened. Here are a few reasons why you may not see open events for your emails:

  1. Refresh your browser tab. If you don't see the tracking lightning bolts in your Sent folder, refresh your browser tab and wait a few seconds for the lightning bolts to appear.
  2. Your recipient is using a tracking blocker or image blocker. We use a tiny pixel to track opens. An open won't be recorded if:
    1. The recipient opens the email on a legacy email client that blocks all images from being viewed. This also means that images in signatures and other media won't carry through to the recipient, so in practice this is quite rare. 
    2. The recipient has software to block email tracking. This is also quite rare, and Mixmax actually circumvents most email tracking blockers.

Click tracking is not susceptible to email tracking blockers, however — so if you see that a link was clicked but an email was not opened, it means that the email WAS opened, but the recipient is blocking images.

If you don't see a lightning bolt on the email, then the email was sent without tracking. Note that the lightning bolt reflects the tracking status of the most recent email that you sent in that conversation. Here are some reasons why you may have sent your email without tracking:

  1. You're on the Free plan and you ran out of tracked emails. You get 100 tracked emails per month on the Free plan. The month re-sets on the first day of each month. 
  2. The email was sent with tracking turned off. You can turn tracking on/off by default in your Tracking Settings, and you can turn tracking on/off for each individual email. Here's more on setting up tracking. Note that if you used a different computer that didn't have Mixmax installed, or if Mixmax was not enabled on your Gmail account, the email will be sent without tracking.
  3. You sent the email from your phone. Mixmax tracks emails that are sent from desktop Gmail. Emails sent from your phone will not be tracked.
