As the title suggests, I was looking for a way to send HTML mails in python using Amazon SES but did not find anything (or maybe my search skills are bad).
So, once I found the solution, I thought I might share it with everyone.

The basic idea is that contents of the mail (raw-message) must be a JSON dictionary with “Data” as main key whose value is a key value pair containing entries with keys like “From”, “To” etc.
Sample code can be seen below.
