Version 1.0 · Effective date: October 15, 2026 · Mailbari LLC
Last Updated: October 15, 2026
Mailbari is for running a legitimate business. Thousands of customers share our mail servers and their reputation, so one person's spam or phishing can stop everyone's mail from arriving. This policy lists what you and your Users may not do. Breaking it can lead to a warning, paused sending, suspension or closure of your organisation, and in serious cases we report it to the authorities.
This policy applies to every Customer, Admin and User, to anyone who uses a Mailbari Booking page or shared link, and to any app or AI assistant that uses the Mailbari APIs or MCP server for a Customer. Customers are responsible for their Users and connected apps.
You may not use Mailbari to store, send, share or link to content that: • Sexually exploits or endangers children in any way (see section 3). • Is illegal where you or the recipient are, or under US or Bangladesh law. • Infringes someone's copyright, trademark, privacy or other rights. • Threatens, harasses, stalks or bullies anyone, or promotes violence or terrorism. • Incites hatred against people because of who they are, including race, ethnicity, religion, caste, gender, sexual orientation or disability. • Shares someone's intimate images without consent, or private personal information (doxxing). • Sells or promotes illegal drugs, weapons in breach of the law, counterfeit goods, stolen data or account credentials. • Defrauds people, including fake invoices, advance-fee scams, investment or crypto fraud, and fake charities.
3.1 Mailbari has zero tolerance for child sexual abuse material (CSAM) and for grooming, sextortion or trafficking of children. 3.2 We use hash-matching technology to detect known CSAM in files and attachments. When we find apparent CSAM, we remove it, close the account, preserve the evidence as the law requires, and report it to the US National Center for Missing & Exploited Children (NCMEC), which works with law enforcement worldwide, including in Bangladesh. 3.3 Customers must not create accounts for anyone under 18.
4.1 You must follow the Anti-Spam & Sending Limits Policy. In short: no unsolicited bulk email, no bought or scraped lists, no hiding who you are, and every marketing email must have a working unsubscribe. 4.2 You may not send phishing messages, pretend to be another person, company, bank or government, forge headers, or use look-alike domains to trick people. 4.3 You may not use Mailbari addresses to sign up for services in bulk, to create fake reviews or accounts, or to get around another service's limits.
You may not: • Send or store viruses, ransomware, spyware or other malicious code, except samples clearly labelled and kept for legitimate security research inside your own organisation. • Try to break into, probe or test any account, system or network without permission, including Mailbari's (see the Security Policy for how to report vulnerabilities safely). • Get around sending limits, quotas, licence counts or other technical limits, for example by sharing one licence among several people or rotating accounts. • Run open relays, proxies or mail forwarding for people outside your organisation. • Overload the Services, or use automated tools to access them except through the documented APIs and within their limits. • Use the Services to mine cryptocurrency or to host files for distribution to the public.
• Give accurate information when you sign up and keep it up to date. • Only connect domains you own or are authorised to use. • Do not share passwords; each person needs their own account and licence. Shared mailboxes and aliases are the right way for a team to share an address. • Turn on two-step login for every Admin. We may require it for all Users. • Tell us at once at [email protected] if you think an account has been compromised.
7.1 You may not use Mailbari's AI features, or an AI assistant connected through the MCP server, to create spam, phishing, malware, harassment, deceptive impersonation or any content this policy forbids. 7.2 AI features use Anthropic's Claude models, so the Anthropic Usage Policy (https://www.anthropic.com/legal/aup) also applies to what you ask them to do. 7.3 You must not present AI-written messages as written by a specific real person who did not approve them, where that would mislead recipients.
Booking pages and Drive share links are for your own business. They may not be used to collect passwords, card numbers or national ID numbers, to imitate another business, or to host content this policy forbids.
9.1 Report spam, phishing or other abuse from a Mailbari address to [email protected]. Please attach the full message with its headers if you can. 9.2 Report copyright infringement to [email protected], following the Copyright & DMCA Policy. 9.3 Report child sexual abuse material to [email protected] and directly to NCMEC at report.cybertip.org. Do not attach the material itself. 9.4 We acknowledge reports within 2 business days. Mailbox providers can also reach us at [email protected].
10.1 Our systems check sending patterns, complaint and bounce rates, malware and known abuse automatically, and we review reports we receive. 10.2 Depending on how serious the problem is, we may: warn the Admins; remove the content or block the message; pause sending for a User or domain; suspend a User, a domain or the organisation; or close the organisation and end the Terms. For serious harm, such as CSAM, phishing campaigns or malware, we act at once without a warning. 10.3 We tell the Admins what we did and why, unless the law or an investigation prevents it. If you think we got it wrong, reply to our notice or email [email protected], and a person who was not involved in the decision will review it within 5 business days. 10.4 We may report illegal activity to the police or other authorities and cooperate with valid legal requests, following our Law Enforcement & Government Request Guidelines.
We may update this policy as new kinds of abuse appear. We will post the new version here with its date and tell Admins of significant changes.
