GitHub Actions push event branch deletion branches filter workflow runs deleted true

💡 Result:

GitHub Actions does not provide a direct workflow-level filter to ignore deleted branches within the push event configuration [1][2]. While the push event payload includes a deleted boolean field (as well as created and forced) [3][4][5], these properties are not available for use in the on.push.branches filter syntax [1][6]. Because the push event is triggered when a branch is deleted, workflows configured to run on push will execute unless you explicitly exclude these events using a conditional job filter [3][7][8]. To effectively filter out branch deletions in your workflow, you must use an if conditional at the job level [7][9]. You can access the event payload using the github.event context [7][9]: jobs: my-job: if: ${{!github.event.deleted }} runs-on: ubuntu-latest steps: - run: echo "This only runs on pushes that are not deletions." Alternatively, if you specifically want to react to branch deletions, it is generally recommended to use the dedicated delete event trigger, which provides access to the branch name via github.event.ref [2][9]. Note that the delete event only triggers if the workflow exists on the repository's default branch [2]. To combine these strategies (e.g., to handle both pushes and deletions differently), you can use multiple jobs or conditional steps with logic checking github.event_name and github.event.deleted [7][9].

Citations:

Exclude deleted branch payloads explicitly.

The push trigger includes branch-deletion payloads. The branches: ['**'] filter matches the deleted branch ref, so the enabled job can send an email for a branch deletion.

Add github.event.deleted != true to the job condition.

In @.github/workflows/push-email-notify.yml at line 15, Update the enabled job
condition in the push workflow to require github.event.deleted != true,
preventing notifications for branch-deletion payloads while preserving
notifications for regular pushes.

concurrency:
# Deliberately per-RUN, so no run is ever queued behind another and none is
# ever cancelled. Do NOT "tidy" this into a shared group such as
# ${{ github.workflow }}-${{ github.ref }}. GitHub's workflow-syntax docs:
# "By default, any existing pending job or workflow in the same concurrency
# group will be canceled and the new queued job or workflow will take its
# place." That happens regardless of cancel-in-progress, which governs only
# the RUNNING job. On this workflow it silently loses a notification email,
# with no error anywhere. Every run here reports a DISTINCT commit, so there
# is no redundant work for a concurrency limit to remove.
# The docs also offer `queue: max` (up to 100 pending); not used, because 100
# is still a cap whereas a per-run group needs none.
# Verified with zizmor 1.30.0: deleting this block raises concurrency-limits;
# this form silences it exactly as a shared group would.

Verify the SMTP endpoint before merging this migration.

The pinned action uses implicit TLS for secure: true and does not implement STARTTLS. If secrets.SMTP_PORT is 587, or the provider does not support AUTH PLAIN, the notification step can fail. Confirm the endpoint and credentials support implicit TLS and AUTH PLAIN.

In @.github/workflows/push-email-notify.yml at line 42, Verify the SMTP endpoint
configuration used by the notification step before merging: ensure
secrets.SMTP_PORT targets an implicit-TLS service rather than port 587 with
STARTTLS, and confirm the provider and credentials support AUTH PLAIN as
required by hyperpolymath/smtp-notify-action.
