We want to have a lambda we can point at an s3 bucket and have it run when files get added. if a file exceeds some variable in size we want the lambda to send an email.
the lambda should have a config for file size, width, height.
we will send emails using sendgrid api, the email will contain the name of the file and a link to it.
please keep the size, bucket info and sendgrid api info in a single config file so its easy to manage.
