Gmail ads appear on the top right or top of the email reading page as the top-most colored message in the "Promotions" tab of the targeted users' Gmail account.

Gmail ads are initially collapsed at the top of Gmail tabs. Your collapsed ads will be expanded to a full email size when clicked. This allows the viewing user to interact with the images and text in your ad. Users who expand your ad can choose to save the ad in their inbox by clicking the star icon or the blue Save button at the bottom of the message. Users also have the option to forward your extended ad to other users as an email message.

Differences between desktop and mobile Gmail

The appearance of Gmail ads you create in the Gmail mobile app may be different from the look in Gmail used on a desktop computer. AdWords optimizes ads to make them look beautiful everywhere. Therefore, your ad can be resized to fit the mobile Gmail format. However, the layout of your ad remains the same.
