Most of my email opens tracked are from the famous Someone. I almost always email multiple people. I understand the tracking pixel cannot be customized when using the HubSpot plugin for Office 365 or other mail clients. However, within the HubSpot browser app or the HubSpot phone apps, it seems reasonable you can create a unique pixel for every person included in the email. At the very least, you should be able to strip out pixels for anyone on the excluded list (like co-workers for my company).  
Without more granular tracking, the feature is rarely helpful and very annoying because of all the notifications. Then it only has value with email marketing campaigns.  
Please consider investing resources to make this feature infinitely more helpful for all your users.

This was discovered in the latest QPR for Android, so you’ll want to take this news with a grain of salt. Hidden within the [code](https://tcstrackings.pk/tcs-courier-rates-pakistan/), we see some new strings that read:

\<string name=”lockscreen\_quick\_affordances\_title”\>Shortcuts\</string\>

\<string name=”keyguard\_affordance\_enablement\_dialog\_message”\>To add the %1$s app as a shortcut, make sure\</string\>

\<string name=”keyguard\_slot\_name\_bottom\_start”\>Left button\</string\>

\<string name=”keyguard\_slot\_name\_bottom\_end”\>Right button\</string\>

Thember’s reply has nothing to do with my idea. I don’t understand what Kanderson5 is saying so it may or may not apply. The issue I raised is to figure out a way to know who opens my emails with the tracking pixel when I email multiple people in one message. There has to be a solution for this.

You can also use the cid parameter in the tracking pixel code to customize the tracking pixel for multiple contacts. The cid parameter is a custom dimension that you can create in Google Analytics. To create a custom dimension, go to **Admin** \> **Custom Dimensions**.

Once you have created a custom dimension, you can use it in the tracking pixel code like this:

```auto
<img src="https://www.google-analytics.com/analytics.js?n=1234567890&cid=1" height="1" width="1" />
<img src="https://www.google-analytics.com/analytics.js?n=9876543210&cid=2" height="1" width="1" />By KBH

Thank you for providing additional information about using the cid parameter in the tracking pixel code to customize tracking for multiple contacts. Custom dimensions in Google Analytics can indeed be a powerful tool for tailoring your tracking needs.

Here’s how you can utilize the cid parameter in the tracking pixel code:

1. **Create a Custom Dimension in Google Analytics** :

2. **Generate Tracking Pixel with the cid Parameter** :
