Email Tools
SPF, DKIM, DMARC, MX — deliverability audited.
Email is the highest-stakes use of DNS. SPF, DKIM, and DMARC records collectively determine whether your mail reaches inboxes or spam folders. These tools surface every signal the receiving server checks.
FAQ
Why does my email go to spam if SPF passes?
SPF alone is necessary but not sufficient. Modern receivers also check DKIM signatures and DMARC alignment. A missing or weak DMARC policy is the most common reason.
