Receive emails when followed crates publish a new release

[rk3141]

Description
I would want to be able to star/pin/follow crates and receive emails regarding updates.

Sorry if this isn't clear, I am not good at describing ideas :|

are you aware that we already have a system to follow crate updates when you're logged in? or is the main request here that we should send those update emails?

The email part.

If this is implemented, I'd like to ask that it be made optional -- and it should probably default to off.

Personally, I use the follow button as a sort of bookmarking system, marking crates I'm interested in using, but I would rather not get emails about that. Beyond that, it may be odd if someone started receiving emails from crates.io out of the blue!

I very much would also like to have this feature. maybe even the option to have a daily digest instead of adhoc emails right when a release arrived.

the problem is that a lot of authors do not align git tags with crates releases so it is sometimes hard to follow all crates releases of packages I am interested in.

and it should probably default to off.

I would argue to make it off for existing users and opt-out for new users. but that is a matter of taste.

with #9064 we now have per-crate RSS feeds, that can be followed as desired. while those are not emails, they achieve a similar result. we are unlikely to implement email notifications for releases in the near future.

@Turbo87 what holds us back from doing emails? Would love to talk about that - or a pwa with native notifications?

[Turbo87]

the extra complexity and the fact that we have a limited budget for sending emails
