Making a mass emailer

So I am the GDSC Lead for my college and as the lead one of my duties is to recruit a talented team of developers, designers and managers called the GDSC Core team. The process was fun and after a lot of interviews I had finally decided my team, and when it came to sending out the emails, I didn't wanna manually send off 20 different mails. Plus the default gmail client doesn't let you send HTML mails anyways, so I wrote a small python script to take a jinja template render it with required info and then mail it off with the Gmail APIs.

Product

The above story strikes an idea that just like there would be multiple people who can not send out well crafted HTML mails. So I decided to make a software solution which I named G-Notify.

Tech specs

Being a student and still a noobie to the developer world, I wanted to learn new things with this project. So I decided with a very elaborate tech stack, here a few things could be could be removed but I got to learn a lot

Nuxt.js --- server side rendering
MongoDB
Express
Google OAuth
Google Cloud Platform --- Storage Bucket and Gmail APIs

Some notable dependencies

Mongoose --- for strict schemas and relations in mongoDB
Puppeteer --- for rendering the html templates and so them (could be replaced but I wanted to try it for a long time)
