Enter your domain or email address. I check the records Gmail, Outlook and Yahoo look at before trusting your mail, and tell you what to fix first.
Checks your domain’s public email setup, live.
How this works
Every result comes from live DNS lookups at the moment you run the check. Nothing is estimated.
These are the records Gmail, Outlook and Yahoo check before trusting your mail. Since 2024, Gmail and Yahoo require SPF or DKIM plus DMARC from bulk senders.
DKIM keys can only be found by name. I try the names common providers use; for a custom one, enter its selector.
Blocklists are included when they answer. Some refuse queries from large cloud networks, and are then left out rather than reported as clean.
This checks your domain’s setup, not individual messages.
