Watch out for

Slack API rate limits can block bulk approval updates, so implement a small delay between posting multiple messages.
Google Sheets webhook payloads may include hidden rows if not filtered correctly, add a check to skip empty or archived products.
Email authentication failures can cause orders to bounce, verify SPF and DKIM records are set up for your sending domain before launch.
Race conditions in status updates can lead to duplicate orders, use a unique transaction ID from Slack as the lock key in Sheets.
