Reliable delivery starts below the surface.
The technical problems behind missed inbox placement — identified and resolved.
After the free check: auth, DNS, and sending in one plan if you want it.
Test your Spam Score - It's free!
Send one test message from your domain. We score spam signals, authentication, and DNS.
Step 1 of 4
Start your email check
We give you a one-time address. Send one message from the domain you want checked — we identify that domain and return authentication, spam-filter signals, structure, DNS, and clear next steps.
What you'll get
- SPF, DKIM, and DMARC results for your message
- Spam-filter and content-structure signals
- DNS and blocklist context with a short fix list
Authentication, reputation, and how mail leaves your stack.
We follow the sending path, fix what is weak, and recheck on a schedule you pick.
Validate authentication
SPF, DKIM, and DMARC reviewed and corrected where needed.
Assess domain reputation
Bounces and complaints reviewed so reputation drift shows in the data.
Harden infrastructure
TLS, routing, throttling, and overall sending health tightened.
After the free check
All sending sources
Marketing, app, and forward paths aligned so tools do not work against each other.
Infrastructure that sends clean mail
TLS, bounces, and rate limits tuned so your stack is not working against itself.
Follow-up you can schedule
Re-checks after changes so you see progress, not a single snapshot.
Help after your report
Send volume, tools, and what you tried. We reply with a fix order and who owns each step.
