Adding Subscribers

Subscribers can be added using API endpoint: POST /addsub

• Send topic and subscriber's email via request body.
• Request body should include keys "topic" and "email".
• "email" provided should be valid email-id.

Creating contents

Contents can be added using API endpoint: POST /addcontent

• All details related to content should be sent such as title, topic, content body and sending time.
• Request body must include keys "topic", "title","content_body" and "send_at".
• The time in "send_at" should be local time of the format "2022-05-05T17:14:00"

Issues

• Cron scheduler is checking to send email for every minute, this makes the scheduling a little less precise in terms of seconds.
• There should be a list of predefined topics to which only subscribers can be added and according to which content should be written.
• Currently, at a time, subscriber is added to a single topic only but there should be feature where subscriber can subscribe to multiple topic at the same time.
• Newsletter is sent as a plain text through email, it can be improved further by using html.
