Frequently Asked Questions
Common questions about email authentication tools
What is email authentication?
Email authentication is a set of protocols (SPF, DKIM, DMARC, BIMI) that verify the legitimacy of emails and protect domains from spoofing. These protocols help ensure emails are delivered to inboxes and prevent phishing attacks.
Do I need all four protocols (SPF, DKIM, DMARC, BIMI)?
SPF, DKIM, and DMARC are essential for email security and deliverability. BIMI is optional but recommended for brand visibility once you have DMARC enforcement in place. Start with SPF and DKIM, then implement DMARC, and finally add BIMI.
Are these tools accurate?
Yes, our email authentication tools perform real-time DNS lookups and use industry-standard validation methods to provide accurate analysis of your email security configuration.
How often should I check my email authentication records?
Check your email authentication records monthly, or whenever you add new email services, change email providers, or experience deliverability issues. Regular monitoring helps maintain optimal email security.
Will proper email authentication improve my deliverability?
Yes! Properly authenticated emails have significantly higher inbox placement rates. Major email providers prioritize authenticated mail and may filter or reject unauthenticated messages.
