A: Hi, thank you for asking.
Yes, the additional credit cost includes the MailBluster email sending cost. Once your email credits are used up, you can continue sending emails at a reduced rate of $0.40 per 1,000 emails (regular price is $0.60 per 1,000 emails). After the credit limit is over, you’ll need to pay separately to both AWS and MailBluster according to the usage. Plus, you won’t have to pay MailBluster’s regular $60 yearly subscription fee.
