Know your emails are set up to reach the inbox
Three technical settings control whether your emails are trusted or rejected. EVOX checks them continuously and tells you exactly what to fix.

Set it up once. We keep an eye on it forever.
EVOX checks your email authentication settings continuously and alerts you the moment something is wrong, with the exact fix written out.

Connect your sending domain
EVOX reads your domain's DNS settings and checks SPF, DKIM, and DMARC automatically. No technical knowledge needed.
Problems are flagged before they cost you
SPF, DKIM, DMARC, and DNS drift are all monitored continuously so nothing slips through quietly.


Get the exact fix, not just a red flag
Every failed check comes with a plain-language explanation and the exact DNS record to publish. No guessing required.
Three settings that decide whether your emails are trusted
SPF, DKIM, and DMARC are not optional extras. Without them, email providers have no reason to trust that your emails are really from you.
What SPF Does and Why It Matters
SPF is a DNS record that lists which servers are allowed to send email on behalf of your domain. Without it, anyone can impersonate your address.
What DKIM Does and Why It Matters
DKIM adds a digital signature to every email you send. The receiving server checks it to confirm the message has not been altered in transit.
What DMARC Does and Why It Matters
DMARC is the policy that ties SPF and DKIM together. It tells receiving servers what to do if an email fails both checks: allow it, quarantine it, or reject it.
Problems Found Before You Launch
Every campaign goes through a pre-send check that includes authentication status. If something is broken, you know before it sends.
You Always Know What to Fix and How
Authentication failures are usually a wrong DNS record. EVOX shows you which one is wrong and gives you the correct value to publish.
Set it up once. Monitored from that day forward.
Authentication is not a one-time setup. DNS records drift, policies change, and configurations break. EVOX keeps watching so you do not have to.



Core checks: SPF, DKIM, DMARC
Continuous monitoring
DNS record fix provided
Alert on any change
Two things most teams do not check until it is too late
Authentication failures are silent. Your emails still appear to send. You just do not know they are landing in spam.
DNS records can change without anyone on your team knowing.
A hosting provider update, a domain transfer, or a misconfigured setting can break your authentication silently. EVOX catches it and alerts you before it affects your sending.

Every fix comes with the exact record to copy into DNS.
No jargon, no guessing. When a check fails, EVOX shows the problem in plain English and provides the correct DNS value to publish right alongside it.

Most deliverability problems are preventable. Authentication is where you start.
Checked continuously
Exact fix always provided
Alerts the moment something breaks
No technical knowledge needed
Everything you need to know
Common questions about Authentication Monitoring in EVOX.
What are SPF, DKIM, and DMARC in plain English?
SPF tells email providers which servers are allowed to send from your domain. DKIM adds a signature to prove your emails were not altered in transit. DMARC is the policy that ties both together and tells providers what to do if either check fails.
Do I need to understand the technical side to use this?
How often are the checks run?
What happens when a check fails?
Is this checked before a campaign sends?
What if my domain is on a public blocklist?

Know your domain is set up right.
Evox checks SPF, DKIM, and DMARC around the clock and tells you the moment something breaks.
