Email Deliverability Monitoring for SPF, DKIM, DMARC & MX
Continuously verify that your email authentication records are present, valid, and correctly configured. Catch a broken SPF record, a missing DKIM key, or a weakened DMARC policy before it sends your mail to spam or opens your domain to spoofing.
Complete Email Deliverability Monitoring Features
Everything you need to keep your email authentication healthy
SPF Record Validation
We check that your SPF record exists, parses cleanly, and stays within the lookup limits — so receiving servers can verify which hosts are allowed to send for your domain.
DKIM Key Checks
Confirm your DKIM signing keys are published and resolvable at the selectors you use, ensuring outgoing mail carries a valid cryptographic signature.
DMARC Policy Monitoring
Verify your DMARC record is present and warn you when the policy is silently left at p=none, so spoofers can't impersonate your domain unchecked.
MX Record Health
Check that your MX records resolve and point to reachable mail servers, so inbound email always has a healthy destination to be delivered to.
Spoofing Protection
Strong, correctly configured authentication stops attackers from sending phishing email as your brand. We flag gaps that leave your domain exposed.
Smart Alerting
Get notified within seconds when a record disappears, becomes invalid, or weakens, via email, Slack, Discord, and webhooks.
Multi-Location Confirmation
DNS answers are re-checked from several regions before an incident opens, so a single stale resolver never pages you with a false alarm.
Historical Reports
Review how your authentication records have changed over time with clear timelines, perfect for auditing changes and proving compliance.
Why Choose Our Email Deliverability Monitoring?
Email authentication is invisible until it breaks — and when it does, your messages quietly land in spam or your domain gets used for phishing. Our monitor watches SPF, DKIM, DMARC, and MX continuously from probe locations around the world, so you learn about a misconfiguration in minutes instead of after customers stop receiving your mail. With multi-region confirmation and instant alerts, it acts as an early-warning system for everything that keeps your email trusted.

How Email Deliverability Monitoring Works
Simple setup, lasting protection for your inbox reputation
Add Your Domain
Enter the domain you send email from and the DKIM selectors you use. We discover your SPF, DMARC, and MX records automatically.
Set Your Expectations
Choose how strict you want to be — for example, alert if DMARC drops to p=none or if any required record goes missing or invalid.
Monitor 24/7
Our global network re-checks your authentication records on a schedule, validating that each one is present, parseable, and correctly configured.
Get Instant Alerts
When a record breaks, weakens, or disappears, you receive an immediate notification and a detailed timeline showing exactly what changed.
Email Deliverability Monitoring Use Cases
Built for any team whose reputation depends on email reaching the inbox
Transactional Email Reliability
Password resets, receipts, and order confirmations have to arrive. Monitoring catches an authentication failure before it quietly routes these critical messages to the spam folder.
Marketing & Newsletter Delivery
Broken SPF or DKIM tanks open rates by sending campaigns to junk. Continuous checks protect the sender reputation your marketing relies on so your emails keep landing in the inbox.
Brand & Anti-Spoofing Protection
A weak or missing DMARC policy lets attackers send phishing email as your brand. Monitoring alerts you the moment your domain's protection slips, before fraudsters exploit it.
DNS Change Safety Net
Records get edited, migrated, or accidentally deleted during DNS changes. This monitor acts as a safety net, catching an authentication mistake right after a change instead of weeks later.
