Check Your SPF Record
Analyze your SPF record, count DNS lookups, and identify potential issues.
SPF (Sender Policy Framework) defines which servers are authorized to send email on behalf of your domain. Exceeding the 10 DNS lookup limit or having syntax errors can cause legitimate emails to fail authentication. Analyze your SPF record to count lookups and catch issues before they impact deliverability.
