About MailReady

MailReady is a free email authentication scanner that checks any domain's SPF, DKIM, DMARC, and MX health in seconds. It explains results in plain business language — not sysadmin jargon — so founders, agencies, and marketing teams can understand whether their newsletters, invoices, and transactional emails are actually reaching the inbox.

Think of it as Lighthouse for email authentication. Your domain's DNS records determine whether your business emails are trusted by Gmail, Outlook, Yahoo, and every other email provider. If those records are missing or misconfigured, your emails may be silently landing in spam.

MailReady was built by @dawntepper_. Because your customers should get your emails.
