About mail4.uk

The domain mail4.uk is powered by kuku.lu, a known disposable email provider. This means any email address @mail4.uk is temporary and will likely become inactive within hours or days.

Users often create addresses on domains like this to sign up for services without using their real email. While convenient for privacy, these addresses are commonly used to abuse free trials, promotions, or bypass verification.
