OTPINB Acceptable Use Policy

Last updated 2026-11-03

Use OTPINB for lawful short-term email tasks and tests you are authorized to perform. This policy applies to guests, Free and Premium accounts, mailbox access and Telegram workflows. Paying for membership or Credits does not exempt anyone from these rules.

Respect people and systems

Do not use the service for spam, unsolicited bulk campaigns, phishing, fraud, impersonation, harassment, threats or distribution of malware. Do not send material you have no right to distribute, attempt unauthorized access, intercept another person's verification messages or misuse exposed personal information.

Only test email flows on systems you own or have permission to test. A publicly readable mailbox is not authorization to enter someone else's account. Respect the destination service's rules; do not use temporary addresses to evade bans, abuse promotions or bypass account restrictions.

Respect service limits

Do not bypass CAPTCHA, IP or account quotas, domain restrictions, send permissions or payment verification. Do not create distributed accounts to evade limits, probe private endpoints without permission, manipulate Credits or Balance, or overload the service with requests. Availability of a public endpoint does not authorize disruptive automation.

Use sending features responsibly and contact only appropriate recipients. Purchased Credits represent sending capacity, not approval for a marketing campaign or a promise that recipients will accept mail. Premium membership does not grant operator-only bulk administration rights.

Handle mail responsibly

Public mailboxes are unsuitable for sensitive information or confidential customer data. Do not publish mailbox credentials, private access links, passwords or verification codes. Avoid opening untrusted attachments or links. Deleting a message cannot retract copies already read, exported or delivered through notifications.

Reporting and enforcement

Report suspected abuse through Contact with a brief description and minimal non-sensitive context. Do not forward malware or private credentials. We may restrict sending, access or other activity when needed to address abuse or protect the service. Reviews depend on the available evidence; a report does not guarantee a particular outcome or response time.
