Why do my emails go to spam?
Gmail, Outlook and Yahoo check three DNS records to decide if an email really comes from you: SPF (which servers may send), DKIM (a digital signature) and DMARC (what to do with fakes). If one is missing or wrong, your emails look suspicious.
What are SPF, DKIM and DMARC?
SPF lists the servers allowed to send email for your domain. DKIM adds a signature that proves the email was not changed. DMARC tells inboxes what to do when SPF or DKIM fail — and sends you reports about who uses your domain.
Why does it say DKIM was not found?
DKIM keys live under a "selector" name that your provider chooses, and it is not public. We check the names used by Google, Microsoft 365, Zoho, cPanel and others. If your provider uses a different one, DKIM may still be on — check in its admin panel.
Does this tool send any email?
No. It only reads public DNS records — the same ones every mail server reads.
Can it tell me if an email address exists?
No. It checks the domain's email setup (everything after the @). Most mail servers — Gmail, Microsoft 365 and many hosts — accept any address when asked, so checking a single mailbox is unreliable, and probing mail servers can get the checker blacklisted.
