This is an exclusive-based, and extra large expandable ad unit that appears in the New Yahoo! Mail after a user sends a message or empties a folder.
The expansion can be user-initiated by roll-over or click. The corresponding action then must also close the expansion. So a roll-over initiated expansion must be closed on roll-out; a click initiated expansion must be closed on click. Click initiated Expandable ads must also contain a close button that contains the word “Close”. The close button must be clear and visible for the duration of the expanded state. We may also move the close button or use our default close buttons to ensure the best user experience possible.
This is not available for the XXL Expandable ad format on Yahoo! Mail.
A video can also play in the Expandable overlay. Sound can be automatically turned on if the overlay itself is click-initiated, or be turned on after a one-second delay if it is roll-over-initiated.
Please provide video asset as FLV (2.2MB or below) or uncompressed AVI or MOV at 30 seconds. Video asset specs for videos in the Expanded panel are negotiable, please liaise with your Yahoo! Sales representative to work out specs that will meet your needs.
Audio (sound only) is also available in the Expandable overlay. The audio asset should be supplied as a WAV or MP3 at around 100KB. There must also be controls to mute the audio.
Extra Flash assets can also be loaded into the Expandable overlay after it loads. The extra assets should be around 100KB each and the total number of extra assets should be less than 5. Preloaders are highly recommended.
Only tags from the following DARLA AJAX approved third party vendors are accepted:
Ad Templates used must be native templates provided by the above vendors. Custom created templates served via these vendors may not work.
