Port the mailing script to Go

[dibyadas]

Better concurrency support.

@arnav-t Can you work on this?

[thealphadollar]

Well, @dibyadas I do not think this is something we need to do ATM and hence, let's reserve resource and man-power for more important tasks. We can do this later, sometime next year.

[dibyadas]

Of course. I never needed it at once. Keep this at low priority.

[arnav-t]

I'm curious, why Golang?

[dibyadas]

Goroutines! 😄

[Ayushk4]

@thealphadollar Let @arnav-t do this, he is practically free. Plus he likes to code in Go, so it shouldn't be an issue for him.
