In February 2019 our form system began delivering submission receipts to writers, containing the information they submitted in it.
If you submitted the form before February 2019 you would not have received a confirmation email by default.
However, if you submitted the form in February 2019 or beyond, you should have received a confirmation email from Google.
This email may have been sent to your junk mail or promotions folder, but in the highly unlikely event you didn't receive it please assume your project details were successfully submitted.
