I created a repository on the Bitbucket. And in Admin tab I found Services configuration. As I understand services allow to integrate with email, twitter and so on. I expected that once I configured a service (email-service, for instance) I would receive email notifications about new changesets (when someone make hg 'push' command). But I don't receive anything.What's the correct way to configure automatic notifications about new changesets on Bitbucket? And what do the services really do? 
Automatic notifications from Bitbucket
email;notifications;twitter integration;bitbucket
It's pretty easy to set up email notifications you just enter the email address that you want the notifications to be sent to.Have you checked that the email hasn't been marked as spam - emails are sent from commits-noreply@bitbucket.orgyou have pushed the changes to the remote server (Bitbucket) and they aren't being pushed to a local repository.the email address you have added is correctComplete information on configuring Bitbucket services can be found here.  In particular email configuration can be found here.
