If a Google Form submission happened but no notification email arrived, the problem is usually not mysterious. It is often one of a few practical setup gaps: the wrong recipient path, the wrong respondent email source, no preflight, no test send, or no post-submit execution check.
Before changing templates or rewriting your form, verify the email path in this order.
The owner alert may be off, additional recipients may be empty, and respondent confirmation may also be off.
If the form does not collect email automatically, the confirmation flow needs an actual Email field.
Preflight is the fastest way to catch missing recipients, missing fields, or setup gaps before launch.
A test send catches template and recipient issues before you depend on the trigger path.
If the email still does not arrive after a real submit, inspect the execution log and latest report.
Save and test-send style checks can look healthy while the real submit-trigger path still needs a separate check.
