Why email checks matter
Small misconfigurations quietly cost you customers.
Most email problems are invisible until they are expensive — a quote that lands in spam, a domain that gets spoofed, a server nobody is watching. A few simple checks surface the risk before it costs you anything.
Stop impersonation
Without DMARC at enforcement, anyone can send mail that looks like you. The right records make spoofing your domain far harder.
Catch failures early
MX, TLS, SMTP and blacklist checks reveal the quiet faults that become outages — so you find out before an angry customer does.
Prove you are set up right
Clear, documented checks let you answer "is your email configured correctly?" with evidence, not a guess — useful for clients and insurers.
Understand the moving parts
Email is many small systems working together. These guides show how each one fits, in plain English, with no jargon to learn.
Know your next step
A check tells you what is wrong; our specialists tell you what to do about it — and can fix it end-to-end if you want it handled.
When to request expert help
A check shows the symptom. A specialist fixes the cause.
These tools help you understand your email. When the stakes are real, hand it to people who do nothing but email — here is how to tell when that is now.
-
Your mail is landing in spam
If important email keeps disappearing into junk, the cause is usually authentication or reputation — we diagnose it at the root and fix it for good.
-
Someone is spoofing your domain
Impersonation and business email compromise are the most expensive email incidents. We move DMARC to enforcement safely so spoofing stops without breaking real mail.
-
You found a problem you cannot read
A failing record, a blacklist entry or a header full of jargon — bring it to us and we translate it into plain English and a clear next step.
-
Email is down or breached right now
If mail has stopped, your domain is blacklisted, or an account is compromised, do not wait on a tool — request emergency support and a specialist gets on it.

Honest about what these tools are
Tool questions
Answers, in plain English.
Are these tools free to use?
Yes. The guides are free to read, and the manual audit that backs them is free too — a specialist reviews your email setup and explains what they find, with no obligation.
Do the tools run a live check right now?
Not yet. Automated, instant checkers are in development as part of our Email Operations Center roadmap. Today, each page explains the check and what a healthy result looks like, and a specialist runs it for you by hand if you request a free audit.
Will you ever ask for my email password?
No. None of these tools ask for passwords or credentials, and they never will. A legitimate email health check never needs your password — anyone asking for one should be treated with suspicion.
Do you store what I type into the forms?
No. The forms on these pages are previews of the coming checkers. They do not submit anywhere, run a live lookup, or store anything you enter.
Which check should I start with?
If your mail is going to spam, start with SPF, DKIM and DMARC. If you are worried about impersonation, start with DMARC. If mail is bouncing or not arriving, start with MX and blacklist. Unsure? Request a free audit and we run them all.
Can you fix the problems these checks find?
Yes. Finding the issue is the easy part — our Email Security, Email Deliverability and Managed Email Support services put it right and keep it right, owned end-to-end.
What if my email is down or breached right now?
Do not wait on a tool. Request Emergency Email Support and a specialist will contain the incident, restore service, and tell you plainly what happened.
Do I need to be technical to use these?
No. Every guide is written for a busy, non-technical owner first, with the technical detail one layer down for those who want it. Translating the jargon is our job, not yours.
