About black.com

black.com is an encrypted email service from Austria. It uses zero-access encryption (AES-GCM-256, key sharing with RSA-OAEP-4096) and runs on Swiss infrastructure. Features include AI-assisted email composition, alias addresses, 25 GB of storage that grows by 2 GB each year and organisation functions with custom domains. The service is fully proprietary; no independent security audit has been published so far, and PGP is not supported. Prospective users should keep this in mind when choosing.
