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.

We discover your SPF, DMARC, and MX records automatically. 2 ### 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. 3 ### Monitor 24/7 Our global network re-checks your authentication records on a schedule, validating that each one is present, parseable, and correctly configured. 4 ### 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. ## Frequently Asked Questions Everything you need to know about email deliverability and authentication monitoring What is email deliverability monitoring?
