# PUSH_EMAIL_ENABLED=true (the single on/off switch). Addresses are pre-filled;

# Re-landed after the 2026-07-20 notification-storm freeze (removed in
# 09f94c5), now on hyperpolymath/smtp-notify-action: Node-free, the SMTP
# session is Idris2-specified and machine-checked, the binary is Zig-built,
# byte-reproducible, and SHA-256-pinned inside the action itself.
name: Push email notification
on:
push: {}
push:
# Branch pushes only: tag and deletion payloads mislabel Branch:/head_commit.
branches: ['**']
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.

GitHub Actions push event branches filter deleted branch github.event.deleted head_commit null official documentation

💡 Result:

When a branch is deleted in a GitHub repository, it can trigger a push event [1][2]. In this specific context, the push event payload includes a boolean field deleted: true [1][3][4]. Because the branch no longer exists, the head_commit field in the webhook payload will typically be null [1][2]. GitHub Actions workflows configured to run on the push event will execute when a branch is deleted unless they are explicitly filtered to ignore these events [3][5][6]. To prevent your workflow from running during branch deletions, you should add a conditional check to your job or step using the if context [4][6][7]: jobs: my-job: if: ${{ github.event.deleted!= true }} runs-on: ubuntu-latest steps: - run: echo "This only runs on regular pushes, not deletions." Alternatively, if you need to perform specific cleanup actions only when a branch is deleted, you can check for the deleted property directly [4]: jobs: cleanup: if: ${{ github.event.deleted == true }} runs-on: ubuntu-latest steps: - run: echo "Performing cleanup for deleted branch: ${{ github.ref }}" There is no native mechanism in the workflow YAML filter syntax (e.g., on.push.branches) to filter out deleted branches specifically [8][9]; the filtering must be handled via conditional logic within the workflow jobs themselves [5][6]. While the delete event exists, it is distinct from the push event and is used for handling the deletion of branches or tags via the specific delete webhook event type [1][10].

Citations:

Exclude branch-deletion push events.

push.branches: ['**'] also matches branch deletions. When enabled, this job can send an email with github.event.head_commit.message empty because deletion payloads have no head_commit. Add the deletion guard:

-    if: ${{ vars.PUSH_EMAIL_ENABLED == 'true' }}
+    if: ${{ vars.PUSH_EMAIL_ENABLED == 'true' && github.event.deleted != true }}

In @.github/workflows/push-email-notify.yml around lines 24 - 25, Update the
push event trigger for the email notification workflow so branch-deletion events
are excluded, while retaining notifications for normal pushes to all branches.
Add the deletion guard alongside the existing push branch configuration,
ensuring runs with no head_commit are not triggered.

# 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.

Remove the unused contents permission.

This workflow and the referenced action do not use repository contents or the GitHub API. Set permissions: {} to limit the GITHUB_TOKEN scope available to the action.

Line 42 selects v0.2.0, while the PR objective specifies v0.1.0 at commit 1b3b752d39a4fe4c0f28f10905e4608789d3e050. Restore the requested pin, or update the objective and review v0.2.0 explicitly.
