[Haskell-cafe] Amazon SES email issues

Sat Apr 30 07:10:52 UTC 2016

David, thanks for the suggestion. Are there any examples on how to send an
email? I've looked through several of the Haskell email packages and have
been able to figure out their APIs easily enough, but this one seems
incredibly complex - almost seem to have to know the internals of SES to
use it effectively and the documentation / examples are scant.
