By following this checklist, you can ensure smooth DNS updates, stronger email performance, and better results for your cold outreach campaigns.
Pre-Update Preparation Checklist
Getting ready for bulk DNS updates isn't just about diving in and making changes. A little preparation can save you from major headaches later, like broken email systems or lost configurations. Here's how to set yourself up for a smooth process.
Audit Domains and Subdomains
Start by listing every domain and subdomain you're using in your cold email campaigns. Verify that each one is active and functioning as expected.
Make sure any subdomain you're planning to update has active email accounts for both sending and receiving. Double-check that SPF, DKIM, and DMARC settings are correctly configured. This step helps you catch potential issues before they disrupt your updates.
"We made progress by organizing a meeting where all departments collaborated to map out exactly how emails move through systems before reaching inboxes. This helped everyone understand the issues clearly." – Matt Bowman, CEO and Founder, Thrive Local
Don't forget to check the sender reputation scores for your domains. A low score could be a sign of DNS issues that need fixing before you proceed. While you're at it, clean up your email lists by removing inactive or invalid addresses. This can significantly improve the performance of your updated DNS records.
For example, conducting a thorough audit in a recent campaign led to a noticeable improvement in email deliverability. Once your domains are verified and any issues addressed, move on to backing up your DNS settings.
Backup Existing DNS Records
Backing up your DNS records is like having an insurance policy. If something goes wrong during the updates, you'll be able to restore your original settings quickly and minimize downtime.
Export your current DNS records in multiple formats and store them on remote servers for added safety. If you're using Windows, PowerShell's Export-DnsServerZone cmdlet is a great tool for this. For other environments, tools like dig, nslookup, or DNSdumpster work well. Be sure to document the date of the backup and confirm that all records are captured accurately across all name servers.
This step is especially important when managing multiple domains for cold outreach. A single error during bulk updates can impact your entire email infrastructure, so having a reliable backup ensures you can recover quickly if needed.
Verify Sending Platforms and IPs
Create a list of all authorized sending platforms and their current IP addresses. This ensures that your DNS updates will authenticate emails from these sources without any hiccups.
Use tools like nslookup and ipconfig /flushdns to verify DNS connectivity and clear local caches, ensuring you're working with the most current data. Confirm that your sending platforms have the necessary permissions for DNS updates and check the DNS suffix search order to avoid conflicts.
Send test emails from each platform to verify that DKIM signatures are functioning correctly. Use online SPF checkers to confirm that all authorized IPs and platforms are included. Review your latest DMARC reports to spot any authentication failures that might signal configuration issues. Keep in mind that DNS changes can take up to 24 hours to fully propagate, so plan your timeline accordingly.
How to Execute Bulk DNS Updates
When handling DNS updates on a large scale, precision and the right approach are key. Here’s how to streamline the process effectively.
Use Automation Tools for Speed
Updating DNS records manually can be a slow and error-prone process. Automation tools can process hundreds of DNS records in just minutes, saving you hours - or even days - of manual effort.
For example, Primeforge offers an automated DNS setup that simplifies the configuration of DKIM, DMARC, and SPF records. Instead of manually handling each record type, you can manage them all from a single interface. The platform also supports bulk DNS updates, making it easy to work across multiple domains at once.
When selecting automation tools, prioritize features like batch processing, error handling with rollback options, and integration with your existing email systems. If you’re comfortable with technical tools, command-line solutions like PowerShell scripts or API-based methods can also be used for automation, though they require a higher level of expertise to execute safely.
Platforms like Primeforge even optimize DNS settings for cold outreach campaigns, ensuring seamless email delivery. Once your tools are ready, focus on timing your updates for minimal disruption.
Schedule Updates During Off-Peak Hours
Timing is critical when making bulk DNS updates. Poorly timed changes can disrupt email campaigns and other services. To minimize impact, schedule updates during off-peak hours.
For US-based operations, the best time is typically 11:00 PM to 5:00 AM EST on weekdays or during weekend maintenance windows. This ensures that most of your audience won’t encounter issues while DNS changes propagate.
Before making updates, adjust the TTL (Time to Live) values of your DNS records. Reduce the TTL from the standard 24 hours to just 5 minutes (300 seconds) about a day or two before your updates. This allows new records to propagate faster across DNS servers worldwide. Once the updates are complete and verified, reset the TTL to higher values to minimize DNS query loads moving forward.
To further reduce risks, stagger updates in batches rather than applying all changes at once. After scheduling, verify that the updates have propagated successfully.
Check DNS Propagation Status
After executing your updates, it’s essential to confirm that the changes have propagated globally. Depending on various factors, DNS propagation can take anywhere from a few minutes to 48 hours.
Use DNS propagation tools to get a global snapshot of your changes. These tools query DNS servers around the world to show which regions have updated records and which still reflect outdated information. DNS Checker is a free tool that provides a quick overview of global propagation, helping you ensure your updates are fully reflected.
For a more detailed check, command-line tools like nslookup (available on Windows) and dig (pre-installed on Linux and macOS) are invaluable. These tools allow you to query specific DNS servers and retrieve detailed information about your records. If you encounter issues, flushing your local DNS cache can help eliminate outdated data.
Pay special attention to your email authentication records. Send test emails to verify DKIM signatures, SPF validation, and DMARC alignment. Some DNS propagation tools also include tests specifically for email-related records, which is especially helpful for cold outreach campaigns.
Finally, set up monitoring alerts to notify you of any DNS resolution failures or stalled propagation in specific regions. Staying proactive ensures you can address potential issues quickly, maintaining smooth operations and optimal email deliverability.
Post-Update Validation and Monitoring
Once DNS propagation is complete, it’s time to validate and monitor updates to ensure your email deliverability stays on track.
Test Email Authentication Records
The first step is to check that your SPF, DKIM, and DMARC records are functioning correctly across all updated domains. These records, stored as DNS TXT entries, are crucial for email authentication, and even minor syntax errors can lead to failures.
Tools like DMARCLY are handy for this. They provide SPF, DKIM, and DMARC record checkers to verify published records and flag syntax errors. For a quick DMARC check, send an email to check@dmarcly.com and receive a detailed authentication report. Similarly, ActiveCampaign offers a reliable DNS record checker for sending domains, which is especially helpful if you’re managing multiple domains for cold email campaigns.
Remember to wait 24 to 48 hours after making updates before running full tests, as DNS changes take time to propagate. If records remain unverified after this period, double-check the values entered in the Name and Value fields. For those using Primeforge, the platform simplifies this process with automated DNS setup and built-in validation for SPF, DKIM, and DMARC records, making it easier to manage multiple domains. Once all records are validated, shift your focus to monitoring performance metrics.
Monitor Email Performance Metrics
After confirming authentication, keep an eye on key email performance metrics to ensure your deliverability and sender reputation remain strong.
Here are the metrics to monitor and their ideal ranges:
| Metric | Target Range | Warning Signs |
|---|---|---|
| Spam Rate | Below 0.1% (ideally under 0.03%) | Sudden spikes after DNS updates |
| Bounce Rate | 0.3% or lower | Consistently high bounces on authenticated domains |
| Delivery Rate | Above 90% | Significant drops tied to DNS changes |
| Spam Complaint Rate | Under 0.1% | Noticeable increases after configuration updates |
For cold emails, aim for an open rate around 23.9%. A significant decline below this benchmark may indicate deliverability issues. Tools like Google Postmaster Tools for Gmail and Smart Network Data Services (SNDS) for Microsoft domains can provide deeper insights into your IP and domain reputation. Regular monitoring of these metrics, along with periodic checks on SPF, DKIM, and DMARC records, is essential for maintaining a strong sender reputation and consistent inbox placement.
Set Up Alerts for DNS Problems
While automation simplifies updates, alert systems are critical for catching DNS issues and performance drops in real time.
Set up automated alerts to monitor DNS resolution and email performance metrics across different regions. This ensures you can quickly identify any areas still accessing outdated records due to uneven propagation. Configure notifications for deviations in key metrics, such as a spam rate above 0.1%, a bounce rate exceeding 0.3%, or a delivery rate falling below 90%.
For cold outreach campaigns, authentication failure alerts are especially important. Notifications for issues like DKIM signature failures, SPF validation errors, or DMARC policy violations can be set up through many email service providers. These often integrate with tools like Slack, email, or SMS via webhooks for real-time updates.
If you’re using a platform like Primeforge, centralized alerting can be a game-changer. Primeforge’s monitoring capabilities allow you to track the DNS health of multiple domains and mailboxes, providing consolidated alerts for any issues that arise.
Lastly, consider using reputation monitoring tools to keep tabs on your IP and domain scores. Sudden drops in reputation often point to DNS or authentication problems. Regularly reviewing these alerts will help you identify recurring issues and fine-tune your monitoring processes to keep everything running smoothly.
