Frequently Asked Questions
What does this deliverability checker test?
This tool checks five critical aspects of email deliverability: SPF records, DKIM signatures, DMARC policies, SSL/TLS certificates, and blacklist status. Together, these determine whether your emails reach the inbox or spam folder.
Why is email deliverability important for cold email?
Email deliverability directly impacts your cold email success. Poor deliverability means your emails land in spam, wasting your outreach efforts. Proper SPF, DKIM, and DMARC configuration can improve inbox placement rates by 40-60%.
How often should I check my email deliverability?
Check your deliverability weekly if you're actively running cold email campaigns. Also check immediately after making DNS changes or if you notice a drop in reply rates.
What's a good deliverability score?
A score of 80+ is excellent and indicates your domain is properly configured. 60-79 is good but has room for improvement. Below 60 means you have critical issues that need immediate attention.
