Email Deliverability Test
Check MX, SPF, and DMARC DNS setup for a sending domain.
When your important emails consistently land in spam folders or never arrive, the culprit often lies in your domain's DNS configuration. The Email Deliverability Test tool is designed to pinpoint these foundational issues. It thoroughly inspects your sending domain's critical DNS records: MX (Mail Exchanger), SPF (Sender Policy Framework), and DMARC (Domain-based Message Authentication, Reporting, and Conformance).
Imagine you've just launched a new email marketing campaign, but your open rates are unusually low. Or perhaps you've migrated your email server, and now internal communications are failing. This is precisely when you'd use the Email Deliverability Test. Simply input your domain name, and the tool rapidly queries DNS servers to retrieve and analyze these records. It provides a clear, actionable report detailing whether your MX records correctly point to your mail server, if your SPF record authorizes your sending IPs, and if your DMARC policy is correctly configured to prevent spoofing.
The typical input is your domain (e.g., yourcompany.com), and the output is a detailed breakdown indicating "Pass," "Fail," or "Warning" for each record, alongside explanations and potential solutions. A key tip: while this tool confirms your DNS setup for sending, it doesn't verify the active receipt of an email or perform a full spam score analysis. It's your essential first step to building a robust email infrastructure and ensuring your messages have the best chance of reaching their intended recipients. Regularly checking these records can prevent common deliverability headaches before they impact your communications.
How to use Email Deliverability Test
Enter Your Domain Name
Navigate to the Email Deliverability Test page and locate the input field. Type or paste the full domain name you wish to check (e.g., example.com), ensuring there are no typos.
Initiate the Test
Click the "Test Deliverability" or similar button to start the analysis. The tool will then query global DNS servers to retrieve the relevant MX, SPF, and DMARC records for your specified domain.
Review the Report
Once the scan completes, a detailed report will be displayed. This report will show the status of each record (MX, SPF, DMARC) with clear indicators like "Pass," "Fail," or "Warning."
Interpret Findings
Examine the results for any "Fail" or "Warning" statuses. The tool will often provide explanations for identified issues and suggest potential corrective actions you might need to take with your domain's DNS settings.
Take Corrective Action (If Needed)
If issues are found, consult your domain registrar or hosting provider's DNS management interface to update or correct your MX, SPF, or DMARC records as per the tool's recommendations. Re-run the test after making changes to verify they are active.
Frequently Asked Questions
What specific DNS records does the Email Deliverability Test analyze?
This tool specifically checks for the proper configuration of your domain's MX (Mail Exchanger), SPF (Sender Policy Framework), and DMARC (Domain-based Message Authentication, Reporting, and Conformance) records.
Does this tool send an actual test email?
No, the Email Deliverability Test does not send any emails. It purely performs a DNS lookup and analysis of your domain's email-related records to assess their correctness and potential impact on deliverability.
What should I do if the tool reports a "Fail" or "Warning" for a record?
If issues are reported, it indicates a problem with your domain's DNS setup for email. You'll need to access your domain's DNS management panel (usually with your domain registrar or hosting provider) and correct or add the missing/incorrect records as advised by the tool's output.
How often should I use this Email Deliverability Test?
It's recommended to use this tool whenever you set up a new domain for email, migrate email services, make changes to your DNS records, or if you suspect your emails are having deliverability issues (e.g., going to spam or not being received).
Can I use this tool to check subdomains?
Yes, you can typically use the Email Deliverability Test for subdomains as well, provided they are configured to send email. Simply enter the full subdomain (e.g., mail.example.com) into the input field.
How does this tool differ from an email spam score checker?
This tool focuses solely on your domain's foundational DNS records (MX, SPF, DMARC) to ensure your email sending infrastructure is correctly configured. An email spam score checker, on the other hand, typically sends a test email to various services and analyzes the content and headers of that email for characteristics that might trigger spam filters.
