AlibabaCloud provides a DirectMail 服务 (相当于亚马逊 SES)! SMTP 或 API 可用于发送批处理电子邮件 (邮件列表) 或触发式电子邮件 (订单确认, 票务系统, 等). 成本低廉: 单价为 $0.29 美元/人 1,000 messages with discounts available from 50,000 每月消息数. But the cherry on the top is that: each DirectMail master account is entitled to 200 free email messages per day which is great for small businesses that want high email deliverability (ie: the emails do not go into the spam folder).
At the moment, there are two AlibabaCloud locations for such service: Singapore and Australia, with a limit of 5 domains per location (所以 10 domains per account). This limit was recently reached and a ticket was opened: within 3 days the limit was lifted!
It is definitely a service that you might want to use, especially for any WordPress installation running WooCommerce!
