Direct Mail:Credit rating rules

Credit rating rules

Direct Mail automatically adjusts your credit rating based on email delivery quality — specifically delivery rate, invalid address rate, and spam rate.

Credit rating

Each Alibaba Cloud account receives an initial credit rating based on overall account standing. The minimum initial rating is Level 2 (2,000 emails/day) and the maximum is Level 16 (10,000,000 emails/day).

View your account status, credit rating, daily quota, and monthly quota on the Overview page of the Direct Mail console.

Upgrade and downgrade rules

Direct Mail evaluates delivery quality every 1 to 2 minutes and automatically upgrades or downgrades your credit rating.

Automatic upgrade mechanism:

• Automatic upgrades are typically capped at Level 8, with a maximum of one upgrade per day. Upgrades do not exceed any credit rating limit you have set.

• An upgrade occurs when you send 300+ emails, use over 70% of your daily quota, and maintain: invalid address rate < 5%, spam rate < 2.5%, and success rate > 92%. The spam rate includes rejected and reported spam.

Automatic downgrade mechanism:

• A downgrade occurs when you send on at least three days per week, average 300+ emails per day, and meet any of: invalid address rate > 9%, spam rate > 10%, or success rate < 65%.

• If an account at Level 1 is downgraded, Alibaba Cloud restricts the account from sending emails.
