Terms of use
Last updated: October 6, 2026
By using Blackinbox, you agree to use the service lawfully and understand its retention and availability limits.
Using an inbox
Use only mailbox credentials assigned to you. You are responsible for keeping your password and any two-factor authentication codes private and for activity performed through your mailbox session.
Acceptable use
You may not use Blackinbox to send email, distribute malware, commit fraud, harass others, interfere with the service, or violate applicable laws or the rights of others. Blackinbox inboxes receive email; they do not provide outbound email sending.
Retention and availability
Messages are automatically removed after seven days. Mailbox addresses are managed by the service administrator and may be changed or removed. Delivery from outside providers, access to the site, and uninterrupted availability are not guaranteed.
Security and sensitive information
Messages are not end-to-end encrypted and can be accessible to service operators with sufficient server privileges. Do not use the service for sensitive or high-risk information. You are responsible for deciding whether an inbox is appropriate for your use.
Changes or suspension
Access may be limited or suspended to protect the service, comply with law, or respond to abuse or security incidents. These terms and service features may change; the current version will be posted on this page.
Contact
Questions about these terms can be submitted through the Contact page. Contact-form submissions are stored for up to 90 days and are not automatically emailed.
