Credit rating rules

DirectMail establishes a dynamic credit rating system based on the email delivery quality (measures arrival rate, invalid address rate, and spam email rate).

After an Alibaba Cloud account is activated and used to log on, different Aliyun accounts will be assigned to different credit levels according to the Aliyun User Level, and the lowest initial credit is Grade 2. This corresponds to a quota of 2,000 emails/day. The highest credit grade is 10, which corresponds to a quota of 500,000 emails/day. The credit grade is adjusted up or down on a weekly basis.

You can view the status, credit level, daily quota and monthly quota of your account on the DirectMail console overview pageDirectMail console overview page.
