Avoid spam folders.
Protect your email deliverability.
DeliverSignal turns raw DMARC reports into plain-English fixes. Find every sender using your domain, stop spoofing, and reach the inbox, without touching a config file.
Monitors every service that sends as your domain
ShopifyLive in an afternoon, enforced in weeks
One DNS record starts the reports flowing. We do the parsing, grouping and translation so you always know the next thing to fix.
Point one DNS record
Add a single DMARC record with your unique inbox address. Reports start arriving within hours, no agent to install.
We aggregate every report
XML from Google, Microsoft, Yahoo and hundreds of receivers, parsed and grouped into one clear picture of your domain.
Fix issues, reach enforcement
Copy-paste DNS fixes for every failing source and a safe path from p=none through quarantine to reject.
Know exactly who sends email as you
Thousands of raw DMARC records become one clean list. Each sending service is grouped, named, and scored by how well it authenticates, so a spoofer stands out at a glance.
- Automatic grouping by sending service
- Pass/fail rates for SPF and DKIM alignment
- New and unknown sources flagged the moment they appear
Reach p=reject without blocking real mail
Enforcement is where most teams freeze. We walk you from monitoring to full rejection one safe step at a time, and warn you before any change would break a legitimate sender.
- A clear checklist for each policy stage
- Copy-paste SPF and DKIM fixes per source
- Alerts the instant a passing sender starts to fail

Teams sleep easier once they can see their mail
“We found three shadow senders in the first week and shut down a spoofing campaign before it reached our patients. The weekly digest is the only report my team actually reads.”
“Getting to p=reject used to be terrifying. The guided rollout meant we never blocked a single legitimate email. It paid for itself the day Gmail tightened its rules.”
“Every other tool dumped raw XML on me. This one told me exactly which DNS line to change and why. I went from 62% to 99% DMARC compliance in a month.”
