For anyone whose email quietly dies in spam
Paste your domain. InboxRadar reads your SPF, DKIM, DMARC and MX the way Gmail and Outlook do, grades it A to F, and tells you exactly what to fix. Free. No login. Then it watches your domain and emails you the moment something breaks.
No signup. Results in about three seconds.
We read public DNS only. We never see your inbox, your mail, or your password. The check lands on a shareable scorecard you can send to whoever runs your DNS.
When SPF, DKIM, or DMARC is misconfigured, mailbox providers silently route your mail to spam or drop it. You find out when a customer says "I never got your email," or when replies just stop. The fixes are small DNS records. The hard part is knowing which one is wrong.
Just the domain you send from. No account, no connecting your mailbox, about three seconds.
We check SPF, DKIM, DMARC and MX from public DNS, exactly the records Gmail and Outlook use to decide inbox or spam.
An A to F grade with a plain-English fix for each problem, ordered by impact. Send it to whoever runs your DNS and it is done.
Deliverability is not set-and-forget: a record gets edited, a DMARC policy quietly weakens, a new tool starts sending as you. InboxRadar re-checks your domain every day and emails you the moment its grade changes, so you hear it from us, not from a customer.
The check and one watched domain are free, for as long as you want. Pro is for agencies and teams watching many domains.
Yes. Every scorecard is free, and watching one domain with daily re-checks is free for as long as you want. No card, no login.
No. InboxRadar reads only public DNS records (SPF, DKIM, DMARC, MX). We never see your inbox, your messages, or any password.
They are the three DNS records that tell Gmail, Outlook and others that mail from your domain is really you. If they are missing or wrong, your mail is far more likely to be filtered to spam. The scorecard explains each one and what to fix.
No tool can read Gmail's private reputation from outside, and we will never pretend to. We check the public records that drive most filtering decisions, which is where almost every deliverability problem starts and is fixable.
