Mail Ads

Yahoo Mail Ads are a companion to the Native Ad and served exclusively in Yahoo Mail. On user-click, the Yahoo Mail Ad displays in the Mail message pane, displaying as if the user had opened a marketing email from the advertiser. Users can interact with the HTML content in the message, forward it to friends and family, save it to their inbox (where it will appear with other incoming email messages), or close it without taking any other action.

Yahoo Gemini Mail Ads turn the prominently placed top ad in the user’s inbox into a native ad that can be read, saved or forwarded, similar to an email. Mail Ads have demonstrated click-through rates as high as 4x industry averages.



The example shown in the video is of a sponsored Mail Ad.


Follow these steps to create Sponsored Mail Ads:

  1. Create a Campaign with the objective set to VISIT_WEB or MAIL_SPONSORED. Note that other objectives will not work.
  2. Create an ad group with a CPC bid for Native.
  3. Create a normal mail ad.
  4. Update the ad field called mailAssetUrl with a URL to a high-resolution image or a compressed HTML file. Note that the image can only be a 2MB JPEG, PNG or GIF image. A compressed HTML file must be a zip file and the maximum file size is 10MB.
  5. Set all levels to Active. If the ad passes approval, it will be eligible to serve within 24-48 hours.


Yahoo Mail Ads cannot be used without a companion Native Ad. Ensure that you prepare Native Ad assets when building this unit.
