Filemail sends files by email or download link. Its free service works without registration and allows up to 5 GB per transfer, with two transfers per 24 hours. Files remain available for up to seven days and are then deleted; the free service also has regional restrictions.
Paid accounts offer different combinations of transfer capacity, storage and management features. Check the current plan details: an account does not automatically mean unlimited transfers or permanent storage. Download shared files before expiry and keep a separate backup for documents that need long-term retention.
