Have you ever received promotional emails or solicitation emails for products you never ordered?
Emails that are indiscriminately and massively sent to third parties are called Spam Email (Junk Email). These not only impose unfair communication costs on recipients but also cause various problems.
GMO Internet, Inc. operates with the policy of providing customers with a comfortable internet experience.
What is Spam Email (Junk Email)?
Spam Email refers to emails that are indiscriminately and massively sent for purposes such as product advertisements, invitations to organizations or businesses, and pyramid schemes.
Emails from unknown senders that recipients receive unintentionally often cause anxiety, irritation, and discomfort.
Unlike postal direct mail, in the world of the internet, recipients bear the communication costs associated with receiving these emails.
How Spam Works
A sender sends spam emails.
An email server used to send spam is registered in a public anti-spam database.
A customer sends an email.
As a result of being registered in a public anti-spam database, many other email servers start rejecting emails from this server.
When tens of thousands or even hundreds of thousands of emails are sent simultaneously, the email server and surrounding network used for transmission become congested. As a result, regular customers trying to send just one email may have to wait for a long time or, without knowing why, have their emails rejected by recipients.
In this way, the damage caused by spam spreads on an immeasurable scale, causing inconvenience even to completely unrelated individuals.
Our Request to Customers
We kindly ask customers using the services of GMO Internet, Inc. to refrain from activities such as sending promotional emails for online shops at a frequency that may inconvenience other internet users or sending a large volume of emails.
How to Check Email Header Information
For information on how to check email header information, please contact your email software provider or mobile carrier.
Checking Email Header Information
Spam emails often have altered "From" (sender) fields, making it necessary to check the email header information, including "Received" (routing details), to determine the true sender. The "Received" field in the header contains the originating information, so please verify the corresponding IP address and intermediary hosts, and contact the relevant service provider.
- ※ If the email is sent using another company's mail server, we are unable to impose any sending restrictions.
Checking the IP Address from Email Headers
- NOTE: The format varies depending on the email software.
