Email Notifications and Filters

Default settings for GitHub can generate a lot of email that can be tough to sift through. Here are some strategies for helping manage these notifications:

  1. Create Gmail filters to help highlight mentions:

    • A filter to get emails out of the Inbox OR
      Skip Inbox, Apply label: github

    • A mentions/me filter to highlight Pull Requests you’re participating in (such as being tagged as a reviewer) to:me
      Apply label: github-me


    Gmail GitHub filters

  2. In GitHub, only have notifications on for repositories you care about (unwatch all others). The 18F org has many repos that do not affect For example, set up “All Activity” for identity- repos, and “Participating” for all others.

Running CI Outside of a Pull Request

Engineers may want to run CI before submitting their code for review. For example, this can be a helpful way to check that all tests pass. To run CI on a branch without creating a pull request:

  1. Push the up to date branch to GitHub
  2. Navigate to
  3. In the drop-down below Run for branch name or tag, select the branch for which you’d like to run CI

Sharing Work With Other Engineers

Engineers might want to share work with other engineers, such as before starting a pairing session. To share work without creating a PR, consider using GitHub’s “compare” feature.

  1. Push the up to date branch to GitHub
  2. From the repo’s home page, select the branch
  3. Click “Contribute” and select the left button, “Compare” Screenshot highlighting "Compare Branch" button
  4. Share the resulting url, eg, with your fellow engineer.

Additionally, you can use a script like git-cmp that allows you to generate github compare urls from local branches.
