Emails that are sent indiscriminately to multiple users regardless of their will are called "spam." To avoid being mistaken for spam, we recommend using the double opt-in method.

The double opt-in method, which confirms the user's intent twice, has the advantage of allowing you to collect only real email addresses, resulting in a highly pure distribution list.

<Double opt-in method flow>
Provisional registration | The user agrees to receive e-mail newsletters by registering as a member or subscribing to e-mail newsletters
Confirmation | A confirmation email will be sent to the email address registered by the user.
Full registration | User clicks on the URL in the confirmation email


The sender information should be clearly stated, and the method for unsubscribing from the newsletter should be easy to understand.
Clearly stating the sender's information and how to unsubscribe from the newsletter gives users a sense of security. It is also essential that the email is in accordance with the Specified Commercial Email Act, including clearly stating a telephone number and address for inquiries.







Point ② | How to send emails without being identified as spam
If you send e-mails without considering the user's reception environment, they may be marked as spam. Always send e-mails in the most optimal way to avoid being marked as spam.



Adjust the delivery speed
For those in charge of email delivery , it is very important to send all emails within a certain time. However, sending a large amount of email in a short period of time puts a strain on the server and risks causing problems. In addition, because sending a large amount of email is a major characteristic of spam, measures are needed to prevent emails from being mistakenly identified as spam.

An effective measure is to use a mail delivery engine to "send the right amount of mail at the right speed." The mail delivery engine can be tuned to the "right amount of mail" and "right delivery speed," so mail can be delivered to users reliably.



Deliver with consideration for the sender's IP reputation
For example, if you suddenly start sending 300,000 email newsletters from a "From" address that previously sent 3,000 email newsletters, your IP reputation may drop. If your IP reputation is low, your emails are more likely to be marked as spam, and they will not reach users' inboxes, leading to a lower delivery rate.

While it is necessary to take measures to improve your IP reputation, you can also try methods such as slowing down your delivery speed.
