I thought SES is the cheapest of all since it's the lowest level? (Compared to Mailgun etc)

  No, especially if you’re expecting emails with large attachments. SES charges $0.09 per 1000 mail “chunks”, where a chunk is 256 Kb of data. This is on top of the base SES fee and S3 operation and storage fees.

    But it only charges for each complete chunk. So < 256KB is free, 256KB is $0.09/1000, etc.

      True, but in my case, I am expecting emails to consist of multiple chunks, on average.
