This happens because your app breaks when it hits orders without email data. Instead of debugging webhook handlers and rewriting validation code, just automate the entire order processing flow.
I’ve seen this exact scenario dozens of times. Set up proper automation that handles all order types from the start. Create workflows that automatically process orders whether they have email, phone, or both.
The automation routes phone-only orders differently, sends SMS instead of emails, and still updates your inventory system perfectly. Set up conditional logic that fills missing data or applies different processing rules based on available contact info.
You’ll never miss orders again, and won’t worry about maintaining complex validation code that breaks every time Shopify changes something. The automation adapts and keeps working.
