Amazon SES costs
When using EmailOctopus Connect you may be charged for the emails you send by Amazon.
Amazon SES charges are based on the total number of emails being sent out from your account each month. Amazon will not charge you anything for the first 62,000 emails you send in a month. If you exceed that, you'll pay them $0.10 for every additional 1,000 emails. More information can be found in Amazon's documentation.
You will not incur any other charges when connecting EmailOctopus to Amazon Web Services.
