AlibabaCloud provides a DirectMail սպասարկում (equivalent to Amazon SES)! SMTP or API can be used to send either batched emails (mailing-list) or triggered emails (order confirmation, ticket system, etc). It is low cost: the unit price is $0.29 USD per 1,000 messages with discounts available from 50,000 messages per month. 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 (so 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!
