Note: The SMTP sending frequency is limited to 5000 times/180 seconds. And this is the frequency from the email client to the SMTP server of Direct Mail. After the email delivered to the server, we will try to quickly deliver the email to the receiving system. Due to the flow control policies of each receiving system are different, please try to take a lower frequency for sending emails within the scope of business in order to improve the delivery success rate.
