Hi @AH2024,
Welcome to the Klaviyo community from across the pond!
Toe be able to submit the branded sender ID Registration for Australia you do need to use a Google account. This can be the same one you use to log in to Google Analytics, or any other gmail account.
If you don’t already have one set up you can create a free simple @gmail.com account here.
The account won’t be used to send any emails to, it’s only a requirement to be able to submit the form.
I hope that helps!
Thanks
David
