Privacy Policy

How we safeguard your corporate credentials, custom domain data, and protect your subscriber lists with absolute sovereignty.

Last Updated: June 10, 2026

01. Introduction

Welcome to Mailstine ("we", "our", or "us"). Mailstine delivers a unified customer database, hosted lead capture architecture, custom domain onboarding setups, and bulk transactional automated email distribution services engineered specifically to grant digital businesses sovereign data control.

We respect the absolute privacy of both our customers (the platform operators who subscribe to our services) and their targeted audience subscribers. This Privacy Policy details explicitly how we collect, store, isolate, process, and completely protect operational files and sensitive delivery metrics.

02. Contextual Privacy Roles

To maintain clear structural integrity under modern global and regional regulations, Mailstine operates under two separate legal distinctions:

Mailstine as a Data Controller

We act as a Data Controller for corporate identity data, authentication parameters, billing references, and server log contexts gathered directly from our subscribing business owners.

Mailstine as a Data Processor

We act strictly as a Data Processor regarding email contact lists, uploaded CSV customer registries, and lead information acquired dynamically through hosted forms deployed by our clients.

03. Information We Collect

We limit data acquisition strictly to values essential for high-performance campaign isolation and delivery validation parameters:

  • Account Profile Identifiers: Corporate registration names, system developer contact emails, and local currency transaction histories.
  • SMTP Infrastructure Configurations: Encrypted custom sending domain validations, validation keys, and remote provider credential parameters required to authorize clean routing.
  • Audience List Assets: Plaintext contact names, telephone links, or specialized custom property fields imported natively via raw CSV files or individual lead capture structures.

04. Processing Engines & Analytics Tracking

To report Campaign Performance Metrics natively without utilizing intrusive global advertising brokers, our background pipelines process structural events using isolated tracking mechanics:

Open-Rate Verification Tracking

Our broadcast system transparently appends a micro-imaging rendering pixel inside outgoing rich HTML distributions. This monitors delivery success and unique open triggers without collecting browser history.

Click-Through Analytics Mapping

Hyperlinks configured in client templates are securely wrapped through automated internal proxy redirects. This maps subscriber interactions and click counts directly within the authenticated dashboard context.

Automated Bounce and Suppression Queues

Our infrastructure engine monitors SMTP responses to catch hard bounces, soft bounces, and complaints. This automatically places failing recipient strings into a localized suppression index to optimize domain health and block spam.

05. Data Sovereignty & Structural Security

Mailstine isolates database clusters securely using modern, high-grade architectural protection parameters to safeguard customer storage sovereignty:

  • Transport Level Encryption: Every transaction channel, system API hook, and browser configuration dashboard instance relies exclusively on modern, high-grade TLS/HTTPS cryptographic layers.
  • Isolate Storage Relays: Subscriber databases, imported lists, and campaign metadata matrices are logically segmented to prevent cross-tenant exposure or database leakage.
  • Credential Security: Third-party API keys and SMTP delivery password variables are stored under rigorous at-rest structural encryption parameters inside our production environments.

06. Regional Regulatory Compliance

As a platform protecting regional business continuity alongside international distribution standards, our operations adhere strictly to modern data frameworks:

NDPR & Nigeria Data Protection Act (NDPA) Realization

We process all regional personal assets in strict conformity with the Nigeria Data Protection Act. We ensure local businesses maintain accessible, predictable, and compliant customer records without reliance on fluctuating foreign currencies or arbitrary foreign jurisdiction locks.

07. Data Subject Rights

Subscribers listed inside any customer segment handled by Mailstine hold absolute rights over their private profile information:

Access

Review all stored metadata tracking tags held within active profiles.

Rectify

Modify account variables or system attributes anytime.

Erase

Completely delete record properties via automated purge calls.

Every broadcast engine iteration dispatched via Mailstine includes an absolute, hardcoded, one-click Unsubscribe Link in the footer layout to guarantee unhindered opt-out capabilities.

08. Retention and Purging Controls

We preserve primary client logs and active user metrics as long as your service subscription tier remains active. If a client purposefully triggers a contact deletion or deletes a subscriber segment group inside the audience dashboard, Mailstine initiates absolute background purging commands to completely wipe records from our live production databases within 30 days.

09. Privacy Engineering Support
