Acrobat Sign Developer Edition activation email not received

We successfully submitted the Acrobat Sign Developer Edition registration for The Hut Hustlers.

The confirmation page stated that an activation email would arrive within approximately 30 minutes.

The email has not arrived, although other Adobe emails are being received normally.

Could an Adobe Community Manager check whether the developer account was provisioned successfully or whether the email address is already associated with an Acrobat Sign account?

We can provide the registered email address privately.
