Exclude deleted branches from the job.

The push event includes branch deletions, and head_commit can be null. branches: ['**'] does not exclude deleted branch refs. The job can send a misleading push email with no head message. Add !github.event.deleted to the job condition. (docs.github.com)

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

[warning] 12-15: insufficient job-level concurrency limits (concurrency-limits): workflow is missing concurrency setting

In @.github/workflows/push-email-notify.yml at line 15, Update the job condition
in the workflow to require github.event.deleted to be false, while preserving
the existing branch matching and other conditions, so deleted-branch push events
are excluded.

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.

Remove the unused contents permission.

This job does not require repository-content access. contents: read still grants GITHUB_TOKEN read access to a third-party action without a demonstrated need. Set permissions: {} unless another workflow contract requires content reads. GitHub supports this form to disable all token permissions. (docs.github.com)

Proposed fix
-permissions:
-  contents: read
+permissions: {}

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
