Privacy Policy

How Resendbox collects, uses and protects information, including the email in your inbox.

Last updated and effective November 7, 2026

1. Introduction and operator

Resendbox is an email client that turns a domain on your own Resend account into a shared inbox. This policy explains what we collect, why, and the choices you have.

We collect only what we need to run the service. Email is sensitive, so we treat it that way.

2. Information we collect

  • Account information: your name, email address and sign-in details. Passwords are stored as cryptographic hashes, never as plain text. If you sign in with Google, GitHub or your company's SSO provider, we receive the basic profile that provider shares, such as your name and email address.
  • Workspace information: workspace names, members, roles, invitations, domains, mailboxes, labels, rules and sender lists.
  • Email content: messages you receive and send through your connected Resend account, including senders, recipients, subjects, bodies, headers, attachments and the original message files. This includes personal data about the people who write to you.
  • Resend connection: access tokens and webhook secrets for the Resend account you connect, which are encrypted before storage.
  • Billing information: your plan, subscription status, billing dates and customer identifiers. Dodo Payments handles card details, and we never receive full card numbers.
  • AI provider details: if you add your own AI provider, its name, your chosen model and your API key, which is encrypted before storage.
  • Technical information: logs needed to run and secure the service, such as request times, IP addresses, device or browser details for your active sessions, errors and security events.

3. Why we process information

  • Running the service: receiving, storing, threading, searching and displaying mail, and sending what you write.
  • Sorting and safety: scoring messages for spam, checking sender authentication, applying your rules and sorting mail into categories. These run automatically on each message.
  • Communication: email verification, password resets, invitations and essential notices about the service.
  • Billing: managing plans, limits and subscriptions.
  • Security: protecting accounts, preventing abuse and enforcing our Terms.
  • Legal compliance: meeting tax and accounting duties, and responding to lawful requests.

4. No sale of data, no AI training

  • We don't sell personal information, and we don't share it with advertisers or data brokers.
  • We don't train AI models on your data. Your email is never used to build or improve AI models.
  • We don't run ads or cross-site trackers. Remote images in emails are blocked by default, so senders can't see when you open a message until you allow them.

5. AI features

Resendbox doesn't include its own AI service. The assistant only works if you add an API key from a provider you choose. Your request goes to that provider, along with recent messages from the open conversation if you leave sharing on. That provider's own terms and privacy policy apply to what it receives.

The assistant only returns draft text. It can't send email or take other actions. Spam filtering and categories don't use your AI provider.

6. Your content and responsibilities

Workspaces decide which domains and mailboxes to connect, and who can access them. You're responsible for having a lawful basis to process the personal data in your mail, and for telling people about it where the law requires that.

For that content, your workspace generally decides how the data is used, and we process it on your behalf to provide the service. Workspace owners and admins can access all of the workspace's mailboxes. You keep full ownership of your content.

7. Third-party service providers

We rely on these providers to deliver the service:

  • Resend: sends and receives your mail through your own account, and sends our product emails.
  • Cloudflare: R2 file storage for attachments and original messages, and network services.
  • Contabo: server hosting for the application, database and queue.
  • Dodo Payments: subscriptions, invoices and payments.
  • Google and GitHub: optional sign-in.
  • Your SSO provider: optional sign-in on the Business plan, chosen by your company.
  • Your AI provider: optional, chosen by you.

We run spam scoring on our own servers, so email content isn't sent to an outside spam service. Resend's own handling of your account is governed by your agreement with Resend.

8. Data retention and deletion

We keep your data while your account and workspace are active. Conversations in Spam and Trash are permanently deleted after 30 days, and you can delete a conversation in Trash sooner.

You can export workspace data and delete your account in Settings. Deleting your account also deletes any workspace where you're the only member. You can also ask for deletion at [email protected].

We may keep some information where the law requires it, such as tax records, or to resolve disputes and prevent fraud. Copies in backups last until those backups are overwritten.

9. Security

  • HTTPS for data sent over the internet.
  • Hashed passwords, secure session cookies and optional two-factor authentication.
  • Application-level encryption for Resend tokens, webhook secrets and AI keys.
  • Access checks that separate workspaces and mailboxes.
  • Sanitizing and sandboxing of email content before it's displayed.

Email isn't end-to-end encrypted. Search and spam filtering need to read it. No system is perfectly secure, so we can't guarantee absolute security.

10. International data processing

Resendbox is operated from Togo. Our providers process data in several countries, and file storage is currently in North America. If you use Resendbox from another country, your data will be transferred to and processed in countries whose data protection laws may differ from yours.

11. Your privacy rights

Depending on where you live, you may have the right to access, correct, delete, restrict or export your personal data, to object to certain processing, and to withdraw consent. You may also be able to complain to your local data protection authority.

To use these rights, contact [email protected]. If your data is in a mailbox run by a Resendbox customer, for example because you emailed them, please contact that customer first, since they control that mail.

12. Cookies and local storage

  • Essential cookies: keep you signed in, protect your session, and secure the connection to Resend.
  • Local storage: remembers your theme, accent and current workspace on your device.
  • Analytics: we use Umami, hosted on our own servers, to count page views across the site. It doesn't set cookies, and we leave query strings out.
  • Session recording: on our homepage only, and only if you allow it, Umami records how you use the page, such as clicks, scrolling and mouse movement, so we can improve it. We don't record any other page, including sign-in and your inbox. You can change your choice any time under Privacy choices at the bottom of the homepage.

13. Children's privacy

Resendbox is for professional use and isn't directed at children. We don't knowingly collect information from anyone under 18. If you believe a minor has given us information, contact [email protected] and we'll delete it.

14. Changes to this policy

When we update this policy, we change the date at the top of this page. For significant changes, we'll also notify you by email or in the app.
