[Send Mail] There is a delay when I try to send my email.
Emails sent to Kakao Mail users are usually sent within three (3) minutes because it is sent straight from the server.

Emails sent to non-Kakao Mail addresses are usually sent within five (5) minutes, but it may be delayed depending on network conditions.
In other words, since the email is not sent directly, but rather sent through multiple servers, if any one of those servers experience an issue or if the network connection is poor, then there may be a delay when sending the email.

If there is more than a one hour delay, a return message is sent to the sender to notify them of the delay.
Please sent the return message to Customer Service and we will look into the issue.
