NEW: Monitor DNS for breaking and churn-related changes
DNS changes can break websites, disrupt email, and even signal customer churn. But what if you could catch those changes before they caused problems?
Most domain monitoring solutions provide only passive, high-level information about your users’ domains.
Entri Monitor provides you with hourly updates on your customers’ DNS settings, allowing you to take action faster, and do more than just monitor for uptime.
Here’s how Entri customers are using Monitor to keep users happy and in their products:
Prevent churn – Get notified when a customer changes their DNS records, allowing you to launch retention campaigns as the churn is happening, instead of after they cancel.
Fix issues instantly – When a user accidentally wipes out DNS records or includes the wrong value, you’ll get an alert so you can take action before it affects their user experience.
Ensure email deliverability – Use Entri Monitor with Entri Connect, webhooks, and our API share links to create a workflow that makes it easy for your users to get–and stay–compliance with bulk sender DNS requirements.
How Entri Monitor Works
1️⃣ Define what to monitor – Simply send a POST request with the domain name and the specific DNS records to track.
2️⃣ Automated hourly monitoring – Entri Monitor checks for changes 24/7 and detects modifications or deletions.
3️⃣ Real-time alerts – When a change occurs, you receive a webhook notification so you can take immediate action—whether that’s notifying the user, alerting your support team, or triggering an automated workflow.

Key Features
Easy API integration – Add Entri Monitor in just a few lines of code and start monitoring instantly.
Comprehensive DNS tracking – Monitor any record type, including DMARC, CAA, SPF, MX, and more.
Data-rich dashboard – See the status of all monitored domains in one place, using the insights for customer retention, support, and deliverability.
Use case: The churn prevention workflow

Say you set up Entri Monitor to alert you when a user updates their CNAME record to point to “Competitor A”.
Here’s how you can configure Entri with your marketing tools to provide actionable alerts that your retention teams can use to recover churning customers:
Step 1
Configure Entri Monitor to pick up on churn signals
Step 2
Configure Entri webhooks with Monitor to trigger marketing automations.
Step 3
Instantly create an Entri Connect API Share Link in the Entri dashboard, and include it in your message to the user.
Step 4
The user gets your churn-prevention offer and API share link, and uses Entri Connect to instantly point their domain back to your solution.
Use case: The deliverability workflow

Email deliverability experts know that DNS requirements are a moving target, especially since 2024. Bulk senders are required not just to set up DNS to connect a custom email domain, but to make periodic updates to their DNS as their email volume increases and fluctuates.
But getting a user–especially a non-technical one–to configure DNS is challenging enough once. How do you improve things like DMARC compliance for such a complex, nuanced process?
Entri Monitor, when used with Entri Connect, is a great way to work on your users’ email security compliance and improve deliverability where DNS isn’t set up optimally.
Here’s how that might work for an ESP:
Step 1
Leadership wants to tackle the growing number of support tickets related to users’ emails winding up in spam. You’re tasked with finding a solution, and your first stop is to take a look at how well your users’ are configuring DNS.
Step 2
Your team configures Entri Monitor to look for and DNS entries that fall outside of how you’re instructing your users to configure SPF, DMARC, and DKIM.
Step 3
You import all existing users’ domains into Entri Monitor for analysis, and configure Monitor to track DNS changes across domains for any new users who sign up.
Step 4
Entri Monitor shows that your users aren’t setting up DMARC very consistently, and that there are many improperly configured SPF records. You use Entri’s webhooks to trigger a marketing email for user IDs associated with those email domains, and send them an email containing an Entri Connect API Share Link.
Step 5
The user gets this email, and rather than try to figure out what the heck a DMARC record is and how to fix it, they click on the Entri powered setup link, and configure DNS automatically according to the configuration you’ve set for Entri Connect.
Bing, bang, boom–instant compliance.
Step 6, optional
Witness the joy of emails delivered, pop some bubbly and celebrate.
With Entri Monitor, you’re always a step ahead of DNS issues.
