Privacy Policy
OneSuite by MailBluster LLC
Effective Date: January 16, 2026
Welcome to OneSuite! Your privacy is important to us, and we are committed to protecting and respecting your personal information. This Privacy Policy explains how Mailbluster LLC (“we,” “us,” or “our”), operating as OneSuite, collects, uses, discloses, stores, and protects your information when you use our services or visit our website at onesuite.io.
By using OneSuite, you agree to the collection and use of information in accordance with this policy. If you do not agree with the terms of this policy, please do not access or use our services.
1. Information We Collect
We collect only the information necessary to operate OneSuite effectively and securely. We follow the principle of data minimization and only collect what is required to provide our services.
1.1 Account & Identity Information
When you create an account, we collect:
- Full name
- Email address
- Postal address (if provided)
- Phone number (if provided)
- User ID and Business ID
- Username, password (hashed), and account preferences
1.2 Email Integration Data
When you connect your email account to OneSuite for CRM integration, we collect and store:
- Email provider information (e.g., Microsoft Outlook)
- Connected email account identifiers
- Email metadata: subject line, sender and recipient addresses, CC recipients, thread ID, direction (sent/received), timestamps, and view status
- Email body content (stored in raw and/or compressed form for CRM display)
Email Sending: OneSuite allows you to send emails on your behalf directly from within the CRM interface. When you send an email through OneSuite, it is transmitted using your connected email account credentials.
1.3 Attachment Information (Metadata Only)
Important: We do NOT store email attachment files. We store only attachment metadata, including:
- File name
- File size
- MIME type

Attachment files are fetched on-demand directly from your email provider when you choose to access them. This approach minimizes data storage while maintaining full functionality.
1.4 Authentication & Security Data
For email integrations, we store:

- Token scopes and expiry information
We never collect or store your email account passwords. Authentication is handled securely through OAuth 2.0 protocols.

We may store:

OneSuite users can connect their own payment processors (Stripe, PayPal, RazorPay, QuickPay) to accept payments from their clients. Each user is responsible for their own payment processor agreements and compliance.
