SPFCheck.dev
Tocca una stella per valutare
SPFCheck.dev is a quick validator that tests your domain's SPF, DKIM, DMARC, and BIMI records in one go, showing you exactly what's published in DNS and flagging any problems. It reports whether your records are correctly formatted, which authentication methods are enabled, and what policy you're enforcing. The interface is clean and doesn't require you to log in or enter anything beyond your domain name.
Use this when you're troubleshooting deliverability issues and want to rule out authentication record problems. It's also handy before you launch a new sending IP or subdomain to make sure everything's configured correctly before mail starts flowing. The tool doesn't store your data, so it's safe for checking customer or client domains too.
