Solo Ads Tracking

For anyone that has experience using solo ads, is there a code I can put in their email so I can track email opens, that way if they are lying about stats I can back up their claims or not?
It's easy for them to lie about how many opens my email got.
I know I can track opens with anything even bit ly links. thanks

I know this is old but you could use a tracker like BeMob. They have a free version.
Create a tracking link that redirects to your offer page and you will see the stats.

Where you buy solo ads btw ?

The way the pixel tracking works in email is by inserting a hidden image at the button of the email. When the client loads the image it goes to a "fake" image page that just adds the click to your server, then returns the image buffer:

Here is the buffer code you can use:

This is written in javascript and all you need to pretty much do is use express.js to host your own custom image page.

add <img> tag with src=bit.ly link that redirects to an actual image (1x1 or something) so it wont look broken...
