Privacy Policy

How MailKatana collects, uses, stores, and protects information across sending, campaigns, contacts, hosted mailboxes, and webmail.

Last updated: April 22, 2026Questions? [email protected]

This Privacy Policy explains how MailKatana ("MailKatana," "we," "us," or "our") handles personal data when you visit our websites, create an account, use our applications or APIs, send email through the platform, operate campaigns, host mailboxes, use webmail, or otherwise interact with our services (collectively, the "Services").

MailKatana is an email platform that lets customers send transactional email and campaigns, manage recipient and event data, and run hosted inboxes and mailboxes with browser and protocol-based access.

1. Scope and roles

MailKatana may act as either a controller or a processor/service provider depending on the context.

  • We act as a controller for data about our own users, workspace members, billing contacts, website visitors, and people who contact us directly.
  • We generally act as a processor or service provider when customers use MailKatana to send email, store mailbox content, manage contacts, or receive inbound mail.
  • If you are an email recipient or someone corresponding with a mailbox operated by a MailKatana customer, that customer is usually the party primarily responsible for the relevant data.

2. Data we collect

We may collect the following categories of personal data:

  • Account and workspace data, such as names, email addresses, roles, authentication details, and workspace membership records.
  • Billing and commercial data, such as plan, subscription, invoice, and payment-related metadata received from payment providers.
  • Configuration data, such as domains, sender identities, mailboxes, aliases, forwarding rules, and mailbox settings.
  • Customer content and service data, such as recipient addresses, contact profiles, event payloads, message bodies, attachments, mailbox content, headers, threads, delivery events, unsubscribes, suppressions, bounces, and complaints.
  • Usage and security data, such as IP addresses, browser or device details, request logs, authentication events, diagnostics, and service performance information.
  • Support data, such as the content of requests, attachments, screenshots, and correspondence you send us.

3. How we use data

We use personal data to:

  • provide, operate, and maintain the Services;
  • create and manage accounts, workspaces, domains, and mailboxes;
  • authenticate users and secure sessions;
  • send and receive email on customer instructions;
  • power campaigns, contact state, events, and workflow logic;
  • process delivery, bounce, complaint, unsubscribe, and suppression events;
  • provide customer support and troubleshoot issues;
  • bill customers and manage subscriptions;
  • communicate product, security, billing, and service updates;
  • monitor reliability, detect abuse, and protect deliverability;
  • comply with legal obligations and enforce our terms.

4. Email and mailbox data

Because MailKatana is an email platform, customers may use the Services to process recipient data, campaign content, message bodies, attachments, and hosted mailbox content. We process that data to provide the Services and not for unrelated advertising use.

MailKatana does not sell customer recipient lists, mailbox content, or message content, and we do not use that data for our own marketing.

We may access limited customer content when necessary to respond to a support request, investigate delivery failures, handle abuse or complaint events, protect the platform, or comply with legal obligations. Customers remain responsible for deciding what data they send or store through the platform and for meeting their own notice, consent, and compliance obligations.

5. Cookies and similar storage

MailKatana currently uses essential cookies and similar storage for authentication, session continuity, security, and basic product preferences. We do not describe advertising cookies in this policy.

If you disable essential cookies or similar storage, parts of the Services may not function correctly.

6. How we share data

We may disclose personal data to:

  • cloud hosting, storage, networking, and infrastructure providers;
  • authentication, payment, security, and support providers;
  • professional advisers such as legal, tax, or accounting advisers;
  • regulators, courts, law enforcement, or other authorities where required by law;
  • successors in connection with a merger, financing, acquisition, or sale of assets;
  • other parties when you direct us to do so or consent to the disclosure.

We do not sell personal data, and under this implementation we do not share personal data for cross-context behavioral advertising.

7. Retention and security

We retain personal data for as long as reasonably necessary to provide the Services, maintain security and reliability, comply with legal obligations, resolve disputes, and enforce agreements. Retention periods vary by data type, customer configuration, and product behavior.

Where mailbox features are enabled, some message states may be subject to service-level retention behavior. For example, mailbox trash may be automatically deleted after 30 days in applicable configurations.

We use reasonable technical, administrative, and organizational measures designed to protect personal data, including access controls, encryption in transit, logging, monitoring, and backup and recovery practices. No method of transmission or storage is completely secure, so we cannot guarantee absolute security.

8. Your rights and choices

Depending on where you live and the role we play in relation to your data, you may have rights to access, correct, delete, restrict, object to, or port certain personal data, and to withdraw consent where consent is the legal basis.

If your request relates to customer-controlled data processed through MailKatana, we may direct you to the relevant customer first. We may also need to verify your identity before fulfilling certain requests.

We may process data in the United States and other jurisdictions where we or our service providers operate. Where required by law, we use appropriate safeguards for international transfers.

MailKatana is a business-oriented service and is not directed to children under 18.

We may update this Privacy Policy from time to time. When we make material changes, we will update the date above and provide additional notice where appropriate.
