How much does AWS cost?

Mailblast sends your emails through Amazon SES, which means AWS bills you separately from your Mailblast subscription. The charge goes straight to the AWS account you connect.

AWS SES pricing

SES charges $0.10 per 1,000 emails sent. New AWS accounts also get a free tier - check the Amazon SES pricing page for the current allowance, since AWS updates it from time to time.

For most senders the cost is tiny. A list of 1,000 subscribers receiving one campaign a week works out to around $0.40 a month in SES fees.
