Comprehensive analysis of email deliverability and sender reputation
Enter your sending domain above to get a comprehensive deliverability analysis.
What we check:
This page provides original, human-reviewed information about email deliverability testing, explaining how MX presence, authentication, and blacklist status combine into an overall deliverability picture for a domain.
Email deliverability refers to the ability of your emails to reach recipients' inboxes successfully. It's determined by various factors including sender reputation, authentication protocols, content quality, and recipient engagement.
Specifies which IP addresses are authorized to send emails for your domain.
Uses cryptographic signatures to verify that emails haven't been tampered with.
Builds on SPF and DKIM to provide policy instructions for handling authentication failures.
Proper email authentication setup is crucial for good deliverability. Follow these steps to configure SPF, DKIM, and DMARC for your domain.
v=spf1 include:_spf.google.com ~allAdd this TXT record to your domain's DNS. Replace with your email provider's SPF include.
DKIM setup varies by email provider. Most providers will give you a DKIM record to add to your DNS.
selector._domainkey.yourdomain.com TXT "v=DKIM1; k=rsa; p=MIGfMA0GCSq..."v=DMARC1; p=quarantine; rua=mailto:dmarc@yourdomain.comStart with 'p=none' for monitoring, then gradually move to 'quarantine' or 'reject'.
SPF: include:_spf.google.com
DKIM: Configure in Admin Console
SPF: include:spf.protection.outlook.com
DKIM: Configure in Security Center
Identify and resolve common email deliverability problems that can affect your sender reputation.
Causes:Poor sender reputation, missing authentication, spammy content

Causes:Invalid email addresses, poor list hygiene, server issues
Solutions:Regular list cleaning, email validation, proper MX configuration
Causes:Misconfigured DNS records, missing DKIM signatures
Solutions:Verify DNS records, check DKIM selector, update SPF includes
Causes:Compromised accounts, spam complaints, poor sending practices
Solutions:Request delisting, improve security, implement double opt-in
Common questions about email deliverability and authentication.
Monitor deliverability metrics weekly and run comprehensive tests monthly.Check immediately after any DNS or configuration changes.
A score above 90 is excellent, 80-90 is good, 70-80 is fair, and below 70 needs improvement.Focus on fixing critical issues first.
While not strictly required, implementing SPF, DKIM, and DMARC together provides the bestprotection and deliverability. Start with SPF, add DKIM, then implement DMARC.
DNS changes typically propagate within 24-48 hours. Reputation improvements can takeseveral weeks of consistent good sending practices.
Authentication is just one factor. Content quality, sender reputation, recipient engagement,and list hygiene all affect deliverability. Consider warming up your IP and improving content.
While technically possible, it's recommended to use separate DKIM keys for each domainfor better security and easier management.
