Mailing service

This service has been created using Python 3.7 and smtplib library to enable you to engage customers across the channel email. The application was deployed in Heroku and actually is used in a large number of service cells of eva conversational flows.

Prerequisites

• Python 3.7+
• Postman
• Cloud account (Azure, GCP, Heroku, etc)

Local testing

• Run the file app.py
• Send this cURL with your fauvorite rest service client (I prefer Postman)

curl --location --request POST '[URL]' \
--header 'Content-Type: application/json' \
--data-raw '{
    "plaintext":"[plaintext]",
    "asunto":"[asunto]",
    "sender":"[sender]"
}'

Where:

• [URL]: Refers to the service endpoint
• [asunto]: Refers to the subject of the message
• [plaintext]: Refers to the content of the message
• [sender]: Refers to the mail sender name
