The signup/sign-in email address was rejected by deliverability screening: disposable-domain or undeliverable addresses cannot create accounts.

Common causes

A disposable/temporary email domain
A mailbox that hard-bounces verification

How to fix it

Use a real, receivable work mailbox. If you believe your legitimate address was misclassified (screening fails open on outages, but classifications can be wrong), contact support — we can allowlist it.

Does it bill?

Not applicable — portal routes are never metered. See Test vs Live Keys for the full billing rules.
