Overview

Dispatch Core is built for people who want real email marketing without renting their audience. It runs inside WordPress, stores subscriber data in your own database, and sends campaigns through your SMTP with safety-first throttling — no third-party platform required.

Perfect for

  • Small businesses doing email marketing in-house
  • WordPress sites needing CAN-SPAM compliant newsletters
  • Teams that want control over subscriber data without relying on third-party platforms
  • Anyone needing reliable SMTP sending with rate limiting and queue management

Core capabilities

  • Safety & compliance — mandatory double opt-in, one-click unsubscribe, CAN-SPAM footer, List-Unsubscribe headers
  • SMTP built in — TLS/SSL support, test send tool, optional fallback to wp_mail()
  • Smart sending — queue-based throttling, pause/resume, automatic retries, real-time progress
  • Campaign tools — Template Mode and Raw HTML editor modes, merge tags, draft workflow, campaign history
  • Subscriber management — statuses, filtering, source tracking, CSV export

The “don’t tank your domain” philosophy

Dispatch sends gradually on purpose. You control emails-per-minute and emails-per-hour so you can ramp up safely and protect your sender reputation. A new domain sending 10,000 emails at full speed is a great way to get blacklisted — Dispatch won’t let you do that by accident.

Simple Licensing. No Games.

We don't believe in dark patterns, forced subscriptions, or holding your data hostage. M Media software products use clear, upfront licensing with no hidden traps.

You buy the software. You run it. You control your systems.

Licenses are designed to work offline, survive reinstalls, and respect long-term use. Updates are optional, not mandatory. Your tools don't suddenly stop working because a payment failed or a server somewhere changed hands.

✓ One-time purchase, lifetime access
✓ No "cloud authentication" breaking your workflow
✓ Upgrade when you want to, not when we force you
✓ Software empowers its owner — not rent itself back

No Bloat. No Spyware. No Nonsense.

Modern software has become surveillance dressed as convenience. Every click tracked, every behavior analyzed, every action monetized. M Media software doesn't play that game.

Our apps don't phone home, don't collect telemetry, and don't require accounts for features that should work offline. No analytics dashboards measuring your "engagement." No A/B tests optimizing how long you stay trapped in the interface.

We build tools, not attention traps.

The code does what it says on the tin — nothing more, nothing less. No hidden services running in the background. No dependencies on third-party APIs that might disappear tomorrow. No frameworks that require 500MB of node_modules to display a button.

✓ Your data stays on your device
✓ No "anonymous" usage statistics
✓ Minimal dependencies, fewer risks
✓ Respects CPU, RAM, and battery
