Note

Ensure that your uploaded filed are not larger than 100k rows. If you have more records to upload, you should break them down into multiple files, or if you wish, you can use the Native Ad Platform API to load larger files.

Important

When you do the upload of your .csv file, Native will lowercase all the email addresses and remove any spaces. Yahoo Native will then encrypt the file to protect the personal data that resides in your email lists. If you wish, you can also perform this task yourself, i.e., lowercase the email addresses and remove the spaces, and then upload the pre-encrypted file. Note, however, that you must use the sha256 as your encryption function; otherwise, Native will not be able to use your files.

Important

If you upload a file with emails unencrypted, Native will encrypt them for you before sending them over the wire to our Verizon system. That’s performed for privacy and security reasons. If you upload a file that is already encrypted, that should work as well, as long as you encrypt all the emails using sha256. That said, we recommend sending unencrypted files to prevent human errors.

If you wish to delete any of your custom audience, simply click the custom audiences checkbox for your audience. Then click the Actions menu item to highlight the audience, and select Delete from the pulldown menu.

Important

When the audience is deleted, all the files associated with that audience are deleted as well. Native Ad Platform will not retain any first-party data.
