Groups for Providing Access

When you create a repository, Bitbucket checks to see if the owner's account has any groups with a default permissions (read, write, or admin) assigned. If you do, it adds that group to the new repository with the default permission.

Adding the issues service:

In the meantime they automated adding the issues service for new repositories. You still have to enable the issue tracker itself, though.

See Enabling an Issue Tracker in the Bitbucket docs.

How the Issues service supports the issue tracker

If you enabled an issue tracker on your repository after August 2012, Bitbucket adds the Issues service automatically for you when you enable the Issue Tracker. Older repositories with older issue trackers may or may not have this service.

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.org
• you 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 correct
