Privacy Policy

Introduction

Send13 ("we," "us," or "our") is an email marketing platform operated by Send13, LLC. This Privacy Policy explains how we collect, use, disclose, and safeguard information when you visit v2.send13.com, use our services, or when our platform processes subscriber data on behalf of our customers.

Send13 operates two distinct data relationships: as a data controller for the personal information of our own customers (the senders who use our platform), and as a data processor for the subscriber lists those customers upload, send to, and manage through Send13.

Please read this Privacy Policy carefully. By using our services, you consent to the practices described in this policy.

Subscriber Data Processed on Behalf of Customers

When Send13 customers upload subscriber lists, send email campaigns, or operate autoresponders through our platform, we process the resulting subscriber data as a data processor under our customers' data controller relationships with their own subscribers. Our handling of this data is governed by our Terms of Service and any applicable data processing addenda.

Subscriber data we process on behalf of customers may include:

• Subscriber email addresses, names, and optional metadata uploaded by the customer
• Engagement events (opens, clicks, bounces, complaints, unsubscribes)
• Send timestamps, campaign metadata, and routing decisions
• Inbound replies routed to the customer's reply address through our reply engine
• Suppression and unsubscribe records

We use the information we collect to:

• Provide and operate the Send13 email marketing platform
• Deliver email campaigns through our sending infrastructure and partner ESPs
• Process inbound replies and route them to your reply address
• Compute engagement classifications and deliverability scoring
• Authenticate API requests, enforce sending limits, and protect platform reputation
• Process payments and send transaction confirmations

Information Sharing and Disclosure

We do not sell, rent, or trade your personal information to third parties. We may share information with:

• Sending Service Providers: Email service providers (such as Amazon SES, Mailgun, SendGrid, and KumoMTA-based relays) and third-party MTAs that deliver email on your behalf at your direction. These providers process subscriber data only to deliver the campaigns you initiate.
• Other Service Providers: Cloud hosting, payment processing, analytics, customer support, and infrastructure vendors. These providers are contractually obligated to protect your information and use it only for the purposes we specify.
• Affiliates: Other companies within the Send13, LLC family of products (including VIP13 and Klean13), where doing so is necessary to provide the services you've requested.
• Affiliate Networks and Offer Partners: Where you operate as an affiliate marketer through our platform, click-tracking and conversion data is shared with the affiliate networks and offer partners you've selected, in accordance with your campaign configuration.
• Legal Requirements: When required by law, court order, subpoena, or governmental authority, or to protect our rights, property, or safety, or that of others.
• Business Transfers: In connection with a merger, acquisition, financing, or sale of assets, your information may be transferred as part of that transaction.

Data Security

We implement appropriate technical and organizational measures to protect personal information, including:

• TLS encryption in transit for all API, dashboard, and inbound email traffic
• SHA3-256 hashing of recipient identifiers at the engagement intelligence layer
• Access controls, authentication, and audit logging
• Network isolation between sending infrastructure, scoring, and public-facing services
• Routine review of dependencies, secrets, and infrastructure
• Encrypted backups with periodic restore testing

While we strive to protect your information, no method of transmission over the Internet or electronic storage is 100% secure. We cannot guarantee absolute security.

Data Retention

We retain personal information for as long as necessary to:

• Provide our services and maintain your account
• Maintain sending history, suppression lists, and compliance records required for email deliverability and CAN-SPAM, GDPR, and CASL compliance
• Compute and serve engagement classifications over rolling time windows
• Comply with legal, accounting, and reporting obligations
• Resolve disputes and enforce our agreements

Upon account termination, customer-uploaded subscriber lists are deleted in accordance with our data retention policy and any applicable data processing addenda. Suppression records and bounce/complaint history may be retained as required to comply with anti-spam law and to protect platform deliverability.

International Data Transfers

Send13 operates infrastructure primarily in the United States. If you access our services from outside the United States, your information may be transferred to, stored, and processed in the United States. Where required by law, we rely on appropriate safeguards such as Standard Contractual Clauses for international transfers of personal data.

Your Rights

Depending on your location, you may have the right to:

• Access the personal information we hold about you
• Request correction of inaccurate information
• Request deletion of your personal information
• Object to or restrict processing of your information
• Opt out of certain communications
• Request a copy of your data in a portable format
• Withdraw consent where processing is based on consent

For requests concerning subscriber data we process on behalf of a Send13 customer, please contact that customer directly — they are the data controller for their subscriber list. We will refer such requests to the relevant customer where appropriate.

California Privacy Rights

California residents have additional rights under the California Consumer Privacy Act (CCPA) and California Privacy Rights Act (CPRA), including the right to know what personal information is collected, request deletion, correct inaccurate information, and opt out of the sale or sharing of personal information. We do not sell personal information.

Cookies and Tracking

Our website and dashboard may use cookies and similar tracking technologies for authentication, session management, security, and analytics. Email campaigns sent through our platform may also use tracking pixels and click-tracking redirects to measure engagement — this is a standard feature of email marketing platforms and is configurable per campaign. You can control website cookies through your browser preferences.

Our website may contain links to third-party websites. We are not responsible for the privacy practices of these external sites. We encourage you to review their privacy policies.

We may update this Privacy Policy from time to time. Material changes will be posted on this page with an updated effective date. For significant changes, we will provide additional notice (such as via email or in-product notification). Continued use of our services after the effective date constitutes acceptance of the updated policy.
