Marketing Email: When sending a large batch of marketing emails, an average of 1 to 3 emails are sent per second. To ensure that each user's email is scheduled at the appointed time, your emails will be sent in sequence with other cloud users. After one user's email is sent, the next one in line will be sent. During special occasions or holidays, there may be a high volume of email sending by cloud users. While the system schedules the emails at the appointed time, it may take some time for the emails to be delivered to the recipients, especially when there is a large number of emails being sent. We recommend that users with time-sensitive content schedule their email sends in advance.

Marketing SMS: The sending rules for marketing SMS are the same as for marketing emails. Once the information is scheduled, the SMS will be sent accordingly. The sending time may vary depending on the volume of SMS being sent on a given day. We advise users with time-sensitive content to schedule their SMS sends in advance.

If failure reports are received by the system after the settlement time has passed,credits will not be reimbursed after the settlement time. However, the number of failures and the reasons for the failures will be synchronized with the system. (In cases where the failure reports are received after the settlement time, it means that the email/SMS has been confirmed as successfully delivered to the client. However, if the recipient blocks the email/SMS or sets it as spam, it may take time for Sendgrid to confirm the status. Nevertheless, at the time of sending, it is considered a "successful delivery" situation, resulting in credit deduction. Therefore, the number of points reimbursed may differ from the final count of failed sends.)
