Replaces dawidd6/action-send-mail with hyperpolymath/smtp-notify-action v0.2.0 (tag commit ede1191ef6ff3ac02c4f4d9efdf837ee517e11d7), per the 2026-09-02 ruling (standards spec §5.5/§9, PR hyperpolymath/standards#725). The whole file is the rsr-template-repo canonical, so besides the uses: line it also: limits the trigger to branch pushes (tag/deletion payloads mislabel Branch:), drops actions: read (unused), and adds timeout-minutes: 5. Dormant gating on vars.PUSH_EMAIL_ENABLED == 'true' is unchanged. Line 1 SPDX header kept as it was.

13-15: Exclude branch-deletion push events.

branches: ['**'] excludes tag refs, but it does not exclude a push event that deletes a matching branch. This can still start notify with github.event.deleted == true and github.event.head_commit == null, producing an email without a commit. Add !github.event.deleted to the job condition. GitHub documents both behaviours. (docs.github.com)

Proposed fix and verification
-    if: ${{ vars.PUSH_EMAIL_ENABLED == 'true' }}
+    if: ${{ vars.PUSH_EMAIL_ENABLED == 'true' && !github.event.deleted }}
#!/usr/bin/env bash
set -euo pipefail
workflow=".github/workflows/push-email-notify.yml"

if ! rg -n 'if:.*github\.event\.deleted' "$workflow"; then
  echo "Missing branch-deletion guard" >&2
  exit 1
fi

42-42: Confirm the previously fixed SMTP port contract remains valid.

The new action defines secure: true as implicit TLS, while this workflow passes secrets.SMTP_PORT. Verify that the secret is 465; a STARTTLS-only service on 587 will fail with this action. (raw.githubusercontent.com)

Verify the pinned action contract
#!/usr/bin/env bash
set -euo pipefail

curl -fsSL \
  "https://raw.githubusercontent.com/hyperpolymath/smtp-notify-action/ede1191ef6ff3ac02c4f4d9efdf837ee517e11d7/action.yml" |
  rg -n -A5 '^  secure:'

printf '%s\n' 'Manual check required: secrets.SMTP_PORT must be 465 when secure is true.'

6-10: LGTM!

📝 Summary

Summary by CodeRabbit

  • Chores
    • Reinstated push email notifications for branch pushes.
    • Added safeguards to prevent overlapping runs, limit execution time to five minutes, and restrict workflow permissions.
    • Updated the email delivery mechanism while preserving the existing notification content.

Walkthrough

The push email workflow now runs for branch pushes only. Each run has independent concurrency and cannot be cancelled by another run. The workflow has reduced permissions, a five-minute timeout, and a SHA-256-pinned SMTP notification action.

Changes

Push email notification workflow

Layer / File(s) Summary
Workflow trigger and execution controls
.github/workflows/push-email-notify.yml
The workflow restricts push events to branches, uses independent per-run concurrency, removes actions: read, and adds a five-minute job timeout.
Pinned SMTP notification delivery
.github/workflows/push-email-notify.yml
The workflow uses hyperpolymath/smtp-notify-action pinned to commit ede1191ef6ff3ac02c4f4d9efdf837ee517e11d7. Existing inputs and email content remain unchanged.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🟡 Moderate · up to 81e92

The notification workflow can send malformed messages for deleted branches, and SMTP delivery may fail if the configured port is STARTTLS-only rather than implicit TLS. Add a deletion guard and confirm the SMTP port contract before merging.

Poem

A rabbit watches branches flow
Each run keeps its own clear row
Five minutes guard the mail
A pinned SMTP action follows the trail
Quiet permissions help success prevail

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win

Add a concurrency policy for SMTP sends.

When PUSH_EMAIL_ENABLED is true, this workflow can run for every branch push, but it defines no concurrency group. A burst of pushes can start multiple SMTP sends and recreate the notification storm described in the header. Add a deliberate serialisation or coalescing policy. Choose cancellation carefully because an SMTP send may already be accepted when a run is cancelled. (docs.github.com)

GitHub Actions push event branches filter branch deletion events github.event.deleted workflow syntax

💡 Result:

In GitHub Actions, the push event includes branch deletion as a triggering activity [1]. When a branch is deleted, GitHub sends a push payload where the deleted property is set to true [1]. Because the push event triggers for both creations and deletions, workflows configured to run on push will execute when a branch is deleted unless explicitly filtered. Workflow Syntax for Filtering Standard branches or branches-ignore filters in the on.push section are designed to filter based on the branch name, but they do not inherently filter out the deletion event itself [2][3]. To prevent a workflow from running when a branch is deleted, you must use a conditional if statement at the job level [4]: jobs: my_job: if: ${{!github.event.deleted }} runs-on: ubuntu-latest steps: - run: echo "This job will not run on branch deletion." Handling Branch Deletion Events If your goal is to trigger a workflow specifically for branch deletions, you should use the delete event instead of push [1]. Note that when using the delete event, the branch has already been removed from the repository, so you cannot check out the code of the deleted branch in the same way you would during a push [5]. Example of a workflow using the delete event: on: delete: jobs: on-delete: if: github.event.ref_type == 'branch' runs-on: ubuntu-latest steps: - name: Handle branch deletion run: echo "Deleted branch: ${{ github.event.ref }}" Summary of key points: - The push event triggers on branch deletion (payload deleted: true) [1]. - Use if: ${{ !github.event.deleted }} in your job to skip workflows during deletions [4]. - Use the delete event if you need to react specifically to the act of a branch being removed [1]. - Workflow filters (branches, tags) target the ref name, not the deletion status [2].

Citations:


Exclude branch deletion events from the notification job.

The push event includes branch deletions, and branches filters do not exclude them. A deletion payload can have head_commit: null. Add && !github.event.deleted to the job condition.
