Know Before You Send

Email deliverability failures are silent—and expensive. Order confirmations disappear. Password resets never arrive. Customers think your site is broken.

M Media Email Deliverability Inspector gives you instant, accurate diagnostics inside WordPress so you can verify your email authentication before messages go out.

What It Checks

  • SPF: Confirms which servers are authorized to send email for your domain
  • DKIM: Validates cryptographic signing with custom selector support
  • DMARC: Checks enforcement policy and alignment
  • MX Records: Verifies inbound mail routing
  • PTR / Reverse DNS: Confirms IP reputation alignment
  • SMTP Test: Send a real test email to confirm delivery works end-to-end

Designed for Real WordPress Sites

This plugin is built for site owners, developers, and agencies who need accurate answers without SaaS lock-in. No accounts. No APIs. No tracking.

Each check includes:

  • Clear pass/fail status
  • Human-readable explanations
  • Actionable guidance when something is misconfigured

Free, Local, and Transparent

No data leaves your server. Deliverability Inspector performs DNS lookups and optional SMTP tests using standard internet protocols. Results are processed locally and can be exported as JSON for documentation or audits.

Works Perfectly with M Media Dispatch

Once your authentication checks pass, you’re ready to send.

M Media Dispatch uses your own SMTP server—no per-subscriber fees, no vendor lock-in, no surprise shutdowns. Deliverability Inspector ensures your foundation is solid before campaigns go live.

Built by People Who Actually Use the Software

M Media software isn't venture-funded, trend-chasing, or built to look good in pitch decks. It's built by developers who run their own servers, ship their own products, and rely on these tools every day.

That means fewer abstractions, fewer dependencies, and fewer "coming soon" promises. Our software exists because we needed it to exist — to automate real work, solve real problems, and keep systems running without babysitting.

We build software the way it used to be built: practical, durable, and accountable. If a feature doesn't save time, reduce friction, or make something more reliable, it doesn't ship.

✓ Every feature solves a problem we actually had
✓ No investor timelines forcing half-baked releases
✓ Updates add value, not just version numbers
✓ Documentation written by people who got stuck first

This is software designed to stay installed — not be replaced next quarter.

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
