Dear customers,

Thank you for using Yahoo! JAPAN Ads.

We will change the specification on creating a custom list for Display
Ads when the linked data type is email address.
Please see the following details.

Once again, thank you for using Yahoo! JAPAN Ads.

1. Product:
 Yahoo! JAPAN Ads Display Ads

2. Schedule:
 June 30, 2021 (Wed)
 *Schedule may change without prior notice.

3. Overview:
 Hashing of the data using salt values is essential when the linked
 data type for creating a custom list is an email address, but we will
 change it to the following specifications to improve user convenience.

 ・Hashing Email Address Data
  Importing non-hashed email addresses will become available (hashed
  email addresses can still be used).
  Note that the maximum number of data in uploaded file is 100,000
  when importing non-hashed email addresses.
  No change on other linked data type.
  *Yahoo! JAPAN Ads API don't support importing unhashed email addresses.
  Hash the email addresses when importing via API.

 ・Salt value
  The salt value will become unnecessary when hashing email addresses.
  Along with this change, acceptance of new application for salt
  values will end on June 30, 2021.
  Note that the imported data hashed by using salt value will become
  unavailable in December 2021.
  Consider to import hashed data without salt value or non-hashed data.

 ・File format for uploading
  We will change the file format to be uploaded for importing data
  -Hashed email address, ad identifier for app
   Compress text file (.txt) to zip file
  -Non-hashed email address
   text file (.txt)
  -Hashed email address, ad identifier for app
   text file (.txt) or compressed text file (.txt) to zip file
