GoKawiilNew service 'I've Sent It' offers signed proof-of-delivery file transfers
A new online courier tool called I've Sent It lets users send files up to 3GB free (3TB on Pro, 5TB on Team plans) without creating accounts or installing software. Senders can lock files with passwords, geo-restrictions, ID verification, or view-once limits, and recipients get a signed certificate confirming who opened the file, when, and where.
