Privacy Policy

Last updated: January 2026

1. Introduction

Mark-Digital, LLC (“MailBeast,” “we,” “our,” or “us”) is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our AI-powered email marketing platform, including our website, applications, and related services (collectively, the “Service”).

By using the Service, you agree to the collection and use of information in accordance with this policy. If you do not agree with our practices, please do not use the Service.

2. Information We Collect

Account Information

When you create an account, we collect your name, email address, company name, and billing information. If you sign up via OAuth (Google or Microsoft), we receive basic profile data from those providers.

Email Account Credentials

To send emails on your behalf, we store SMTP and IMAP credentials for your connected email accounts. These credentials are encrypted at rest using AES-256 encryption and are never shared with third parties.

Campaign Data

We store your campaign content, lead lists, email sequences, and associated metadata. This includes recipient email addresses, names, and any custom fields you provide for personalization.

Usage and Analytics Data

We collect engagement metrics (opens, clicks, replies, bounces) to provide analytics and optimize your campaigns. We also collect service usage data such as feature interactions, session duration, device information, IP addresses, and browser type.

Payment Information

Payment details are processed by our payment processor, Stripe. We do not store complete credit card numbers on our servers. We retain transaction records for billing and accounting purposes.

3. How We Use Your Information

We use the information we collect for the following purposes:

  • To provide and maintain the Service, including sending emails, managing campaigns, and processing replies
  • To power AI features such as reply classification, OOO detection, and content optimization
  • To provide analytics and performance reporting on your campaigns
  • To manage email warmup and deliverability optimization
  • To process payments and manage your subscription
  • To communicate with you about your account, updates, and support requests
  • To detect and prevent fraud, abuse, or violations of our Terms of Service
  • To improve our Service through aggregated, anonymized usage analysis
  • To comply with legal obligations

4. Legal Bases for Processing (GDPR)

If you are in the European Economic Area (EEA), United Kingdom, or Switzerland, we rely on the following legal bases for processing your personal data:

  • Contractual Necessity: Processing necessary to perform our contract with you (providing the Service)
  • Legitimate Interests: Processing for our legitimate business interests, such as improving the Service, fraud prevention, and marketing (where these interests are not overridden by your rights)
  • Legal Compliance: Processing necessary to comply with applicable laws
  • Consent: Where you have given consent for specific processing activities

5. AI Processing

Our AI features process email content to classify replies, detect out-of-office messages, and optimize sending patterns. AI processing occurs on our secure servers and through our AI service providers.

  • We do not use your email content to train general-purpose AI models
  • AI-generated insights (classifications, confidence scores) are stored as part of your campaign data
  • Third-party AI providers (such as OpenAI) process data under data processing agreements that prohibit use for model training

6. Data Sharing

We do not sell your personal information. We may share data with:

  • Service Providers: Infrastructure hosts (AWS), payment processors (Stripe), and email delivery partners necessary to operate the Service
  • AI Providers: We use OpenAI for certain AI features. Data sent to AI providers is subject to their data processing agreements and is not used for model training
  • Analytics Partners: We may use analytics services to understand Service usage
  • Legal Requirements: When required by law, subpoena, court order, or to protect our rights, property, or safety
  • Business Transfers: In connection with a merger, acquisition, bankruptcy, or sale of assets, where your information may be transferred to the successor entity

7. International Data Transfers

We are based in the United States, and your information may be transferred to and processed in the United States or other countries where our service providers are located. When we transfer personal data from the EEA, UK, or Switzerland, we implement appropriate safeguards such as Standard Contractual Clauses (SCCs).

For more details on our data processing practices as a processor, see our Data Processing Addendum.

8. Data Security

We implement industry-standard security measures including:

  • Encryption at rest (AES-256) and in transit (TLS 1.3)
  • Role-based access controls and multi-factor authentication
  • Regular security audits and vulnerability assessments
  • Isolated data environments per organization
  • SMTP credentials stored with additional encryption layers
  • Continuous monitoring and intrusion detection

  • Account Data: Retained while your account is active and for 30 days after deletion request
  • Campaign Analytics: Retained for 24 months after campaign completion
  • Payment Records: Retained as required by tax and accounting laws (typically 7 years)

Email Tracking: Our tracking pixels in emails are used solely to measure campaign performance for our customers (open rates, click rates). This data is provided to our customers as campaign analytics.

Do Not Track: Our Service does not currently respond to Do Not Track browser signals, as there is no industry-standard interpretation of such signals.

13. Children's Privacy

The Service is not intended for use by individuals under the age of 16. We do not knowingly collect personal information from children under 16. If we learn that we have collected personal information from a child under 16, we will take steps to delete that information promptly.
