Precautions Before Delivery

To prevent emails sent using NHN Cloud Email service from being treated as spam by an external email service, you should keep in mind the following.

First, DNS must be set up.
Since it is sent with email address containing a user-owned domain through NHN Cloud Email service's Mail delivery (SMTP) server, additional settings are required in DNS where user-owned domain is serviced. For more information about additional DNS settings, see Domain Management Guide.

Starting from February 1, 2024, Gmail sender guidelineswill change and send requests to some receiving mail systems may be rejected if you do not have domain authentication and SPF, DKIM, and DMARC authentication.

Second, Gmail uses domain reputation as a primary criterion for determining spam. If a sender with a low domain reputation sends a high volume of emails at a high speed, or sends advertising emails that the recipient doesn't want, the emails are stored in their "inbox" but with warning or stored in their ‘spam’ folder, or the recipient can slow down or deny the emails. Therefore, if you want to send out emails in bulk, you should always take care to keep your domain reputation high by referring to the following guide on how to manage your domain reputation.
