When analyzing DNS logs for email marketing, pay attention to the following:
SPF Records: Ensure that your SPF records are correctly configured. Any failures here could result in your emails being marked as spam. DKIM Signatures: Verify that your DKIM signatures are properly aligned and validated. Misalignments can also lead to deliverability issues. MX Records: Check your Mail Exchange (MX) records to ensure that they point to the correct mail servers. Reverse DNS: Ensure that your IP addresses have proper reverse DNS records. This helps in building your domain's credibility.
