For your information our product team has blocked email send feature in SBCA for Trial accounts. This affects all customers including Asia.
The reason for this is that it was discovered that some trial accounts are using the email service to do mass email campaigns.
The result is our email service is now blacklisted as spam and impacted our paying customers.
The blocking is temporary.
They are also looking at longer term solution.
We will get back to you if everything back to normal.
We sincerely apologize for any inconvenience.
