Credit rating rules
Direct Mail uses a dynamic credit rating system based on email delivery quality. This quality is measured by metrics such as delivery rate, invalid address rate, and spam rate. The system automatically adjusts your credit rating. For more information, see the upgrade and downgrade rules below.
Credit rating
When you activate your Alibaba Cloud account, you are assigned an initial credit rating based on your account's overall standing with Alibaba Cloud. The minimum initial credit rating is Level 2, which corresponds to a daily quota of 2,000 emails per day. The highest credit rating is Level 16, which corresponds to a daily quota of 10,000,000 emails per day.
You can view your account status, credit rating, daily quota, and monthly quota on the Overview page of the Direct Mail console.
The following table shows the relationship between credit ratings and daily quotas:
Credit rating | Daily quota (emails) |
Level 1 | 500 |
Level 2 | 2,000 |
Level 3 | 5,000 |
Level 4 | 8,000 |
Level 5 | 10,000 |
Level 6 | 20,000 |
Level 7 | 50,000 |
Level 8 | 100,000 |

Upgrade and downgrade rules
Direct Mail evaluates your email delivery quality in real time every 1 to 2 minutes. This evaluation uses metrics such as delivery rate, invalid address rate, and spam rate. Credit ratings are upgraded for high-quality users and downgraded for low-quality users. The upgrade and downgrade rules are as follows:
Automatic upgrade mechanism:
The maximum level for automatic upgrades is typically Level 8. Your account can be automatically upgraded once per day. The upgrade will not exceed any credit rating limit that you have set.
Your credit rating and daily quota are upgraded if you send 300 or more emails, use over 70% of your daily quota, and maintain an invalid address rate below 5%, a spam rate below 2.5%, and a success rate above 92%. The spam rate includes emails that were rejected as spam and emails that were reported as spam.
Automatic downgrade mechanism:
Your credit rating is downgraded and your daily and monthly quotas are lowered if you have sending data for at least three days a week, send an average of 300 or more emails per day, and meet one of the following conditions: an invalid address rate above 9%, a spam rate above 10%, or a success rate below 65%.
If an account at Level 1 is downgraded, Alibaba Cloud restricts the account from sending emails.
The Direct Mail team reserves the right to adjust these rules and values based on system conditions.
