This utilit serves as a quick test to check if email sending is working, without you having to click a bunch of buttons on the web UI such as creating a new user:
cd web
OURBIGBOOK_SEND_EMAIL=ses \
OURBIGBOOK_SEND_EMAIL_SES_REGION=us-east-1 \
OURBIGBOOK_SEND_EMAIL_SES_USERNAME=access-key \
OURBIGBOOK_SEND_EMAIL_SES_API_KEY=secret-access-key \
bin/send-email user@mail.com 'My subject' 'My body'
