Frequently Asked Questions

Does MailReady send any emails?

No. It runs DNS lookups and safe SMTP capability checks (like STARTTLS support) without sending email content.

Why can my score be low even if SPF exists?

A weak SPF policy, missing DKIM, permissive DMARC, blacklist hits, or poor TLS/PTR setup can still tank deliverability.

Can I check customer domains too?

Yes. Any public domain can be scanned. Great for agencies and cold email teams doing pre-flight checks.
