Just came across your channel. One word "FABULOUS". Keep up the good work.
Future suggestion:
1. Web crawler
2. Yelp
3. Api limiter and BOT blocker

Super and correct - I myself was part of Notifications Team in a big product base company. And the architecture was same.

the whole bulk send notification recipient filtering module should NOT be part of the notification system. One of the first priorities of microservice / saas design is to define service boundary. The notification recipient gathering logic should be provided from external services/clients. Also can use some extensive topics (P2 or PN): maintain message order; What if associate is offline / message handlers throw exception; can we guarantee at least once delivery? what if publisher needs only once delivery?

[JoseMoralesM]

Your videos are amazing, thanks for the teachings ! . You should continue adding more ^^

[maheshsadashiv]

Maybe we can also add a leads service to target users with specific notifications. Great job with the amazing explanation!!

[adilsheikh]

Always a great content on this channel but this time I felt that the system has been complicated this time.

[rohanarora]

One suggestion could be that we could have an admin dashboard for the all templates. That means that we can update those templates on the fly and all the clients send that key to us.
