When you create an AWS Account, you need to add a new payment card to your AWS account and an authorization charge of $1.00 is sent to verify that the billing card is valid and that the card hasn’t been reported lost or stolen.
For all AWS customers, the temporary authorization charge is $1.00. AWS doesn’t proceed with the charge, and the charge should disappear within three to five business days. The authorization charges for prepaid credit cards might vary.
You also need to activate your AWS account by verifying your email address and mobile number. And AWS will deduct $1.00 from your card after verifying it. If all these goes well, your AWS account will be activated.
When you start to use Amazon SES, you will be in Free Tier with a limit of 3000 emails per month upto 1 year. Once you exceed this limit, Amazon SES will most likely charge you $0.10 for every 1000 emails you send from your AWS Account. This charge is solely part of Amazon Web Services, not MailBluster.
