[erlang-questions] error notification via mail

[Max Lapshin]

You should definitely look at hoptoad (airbrake.io).

When you serve many clients, error may repeat up to several thousands
times per second and it is impossible to send such amount of email.
This is why you should launch agent, that collects errors, aggregates
them and send only cumulative error message.

I advise to take a look at hoptoad protocol: there are agents for many
languages.
