Make your email trustworthy — and deliverable
Email authentication is a handful of DNS records — SPF, DKIM, DMARC and their newer companions. Get them wrong and two things happen at once: anyone can send mail in your name, and your own mail quietly lands in junk folders. MailControl fixes both.
Email fails silently, in both directions
Nobody tells you that your invoice went to spam, and nobody tells you that a fraudster is sending mail as your domain. Both problems come from the same place: DNS records that are missing, weak, or drifting.
Anyone can send mail in your name
Without a properly enforced DMARC policy, spoofing your domain is trivial — and your customers and suppliers have no way to tell a forged invoice from a real one.
Your own mail lands in spam
Receiving servers judge you by your SPF, DKIM and DMARC records. Weak or missing records mean legitimate offers, invoices and password resets get filtered — and you never find out.
Records drift and nobody notices
A new mail tool gets added, an SPF record gets edited, a DMARC policy gets loosened "temporarily". Each change is invisible until deliverability drops or a spoof gets through.
From "what is DMARC?" to enforced and monitored
Deliverability and defence from the same records.
The same DNS records that stop fraudsters from spoofing your domain are the ones receiving servers use to decide whether your mail reaches the inbox. MailControl keeps both sides honest — continuously, not as a one-off audit.

Frequently asked questions
What email records does TrustCtrl monitor?
MailControl monitors SPF, DKIM, DMARC, MX, BIMI, MTA-STS and TLS-RPT for each of your domains and rolls them into one mail-health view. Every gap comes with a plain-language explanation, and the DNS setup guide provides copy-ready records for DMARC, MTA-STS and TLS-RPT.
How do I find out who is sending email as my domain?
MailControl ingests DMARC aggregate (RUA) reports — the feedback receiving mail servers send about mail claiming to be from your domain — and turns them into a clear picture of every sender. Legitimate sources like your mail servers and newsletter tool are visible, and unauthorised senders are flagged.
Does weak email authentication really affect deliverability?
Yes. Receiving servers use your SPF, DKIM and DMARC records to decide whether your mail is trustworthy, so weak or missing records push legitimate mail towards spam folders. The same records also stop others from sending mail in your name — fixing them improves deliverability and defence at once.
