If you are using a Docomo mobile phone carrier email address

Dear Valued Customers,

Thank you for your continued patronage of our products.

We have been receiving many reports of emails not reaching customers who use mobile carrier email addresses.
In particular, we have received numerous inquiries from customers using "@docomo.ne.jp" addresses, so please click here for more information. This page also provides instructions on how to set up your email.

If you are using a mobile carrier email address, emails may not be delivered if your spam filter settings are set to the default. Therefore, we recommend placing orders using an email address that can also be accessed from a computer.

If you wish to use a mobile carrier email address, please register the "@ganso-sample.com" domain as a receivable address in your domain settings.

Customers using docomo should register our domain to their reception list using the following method:

  1. Tap "Mail Settings" from the menu in the "docomo Mail" app to display the docomo Mail settings page.
    Alternatively, tap "Mail Settings" from "mydocomo" to open the settings menu.
    *You will need to log in to your d Account. If you have any questions about logging in, please contact your mobile carrier.
  2. Tap "Specified Reception / Rejection Settings" or "Reception List Settings" within the "Spam / SMS Countermeasures" menu.
  3. Check "Use settings", then add "@ganso-sample.com" from "Register emails to receive", tap "Confirm settings", and register it as a receivable domain.

The display and operation of menus may vary depending on your device model and usage.
For more detailed setup instructions, please contact your mobile carrier.


We apologize for the inconvenience this may cause and ask for your cooperation in checking these settings.
