django-anymail VS blackbox_exporter

I would strongly suggest that you take a look at the django-anymail package. Using it will allow you to be able to swap between ESPs (if you are no longer please by their services) without having to refactor your code (switching packages/sdk). It has been a big time saver in a project of mine and the maintainer of the package responds quickly to any issues or questions you might have.

Once you switch to a transactional email service provider like mailgun, sendgrid or SES (as others have suggested), also take a look at the django anymail project: https://anymail.dev/ for a super seamless integration.

Popular answers include DRF, django-extensions, anymail, allauth and the DJDT.

I use django-anymail as the email backend. It hooks into Django and allows you to easily swap in and swap out different email providers. That way you're provider agnostic and can avoid vendor lock-in. Did Sendgrid hike their prices? Change three lines of code and use Amazon SES.

So you need 2 modules, one for each ip version. As for autamating setting these up, we deploy our Prometheus server with salt so we can use Jinja templating in all our Prometheus config files. That really cuts down on repeating boiler plate code.

This is also interesting for other reasons; in host downtime situations you can sometime see they will drop one type of traffic and not the other.

A Pi is more than enough to run a full monitoring stack. Why reinvent the wheel?

You can also use the blackbox_exporter to probe various endpoints. But in reality, you don't need to do this most of the time since the up metric gets you what you want.

Synthetic Monitoring is the Grafana Cloud implementation. It uses the blackbox_exporter

Prometheus blackbox_exporter. Free and open source.

Check something called blackboxexporter https://github.com/prometheus/blackbox_exporter

I have seen some people doing with these traditional relational databases, and I was wondering if it could be a good fit for prometheus+grafana as I have been messing around with prometheus BlackBox exporter (https://github.com/prometheus/blackbox_exporter) for web status monitoring.

You should look into the projects https://github.com/prometheus/node_exporter and https://github.com/prometheus/blackbox_exporter

You could use prometheus as a monitoring tool, blackbox_exporter to "export" the urls to prometheus, alertmanager for notifications, and grafana for nice gui dashboards (and maybe also notifications).
