Publishers are required to include a link to Google's "About this ad" page below their newsletter ad creative by adding the following code snippet.
Example
<a href="https://securepubads.g.doubleclick.net/gampad/jump?iu=EXAMPLE_AD_UNIT&clkk=EXAMPLE_CLKK&click_type=wta">Why this ad?</a>
The code snippet is automatically included in the newsletter tag generated from the Ad Manager UI so that publishers aren't required to carry out this step.
Reporting
A newsletter ad impression is recorded when Ad Manager responds to an ad request.
You can also filter by "Email/Newsletter" using the "Inventory type" dimension to analyze data for newsletter ads only.

Frequently asked questions
Can I reuse clkk values across multiple newsletter tags?
clkk value may cause users to land on the wrong page or a blank page, and inaccurate reporting.How do I know if clkk is set up correctly?
When clkk is set up correctly, it generates a string that's unique per user, and per email send. To verify this, you can send out test emails. You should be able to click on the ad, land on the correct destination url and clicks are then reported.
If the clkk has only one merge tag variable, then it's most likely wrong because you likely need more than one merge tag variable to form clkk.
Can I use the same line item for both newsletter and display ad units?
How do I show different creative sizes depending on the device type/screen size?
The publisher can upload a single creative and use CSS @media queries to dynamically resize the creative based on browser viewport size. In the example below, if the screen size is at most 480px (for example, on a mobile device), then the creative is scaled to 100% of the parent container width; if the screen size is at least 480px (for example, on a desktop), then the creative width is 50% of the parent container width (the aspect ratio of the creative does not change as long as the size of the img element is not defined.)
