Free tools
Check mail security and SPF before you sign up.
Run public domain and mail checks without a My NovaMX account. Create an account when you are ready to register a domain, order hosting or MailControl.
What you get
Readable checks, not raw dumps
Each free check explains whether a record is present and what usually needs attention next. Results stay on this page. They do not change your DNS until you publish records yourself or order a NovaMX service.
- Mail security check: SPF, DKIM, DMARC, BIMI and TLS-RPT presence
- SPF lookup: record shape and DNS lookup count against common limits
- Domain check: availability and registration price before checkout
Mail security
Mail security check
Check SPF (policy and lookups), DKIM, DMARC (policy and reporting), BIMI, TLS-RPT, MTA-STS, MX, DNSSEC delegation, and website HTTPS/HSTS. Warnings include the risk of leaving it as-is, and a direct way to order products that help. Entering www uses the organisational domain.
SPF lookup
SPF lookup check
Validate SPF records and lookup counts for a domain or full v=spf1 record.
Paste a domain name or a full v=spf1 record.
Domain availability
Domain check
Check whether a domain name is available and see the registration price. To register or transfer, create a My NovaMX account and complete checkout.
After you run a check

FAQ
Questions about the free tools
Do I need an account to run a mail check?
No. Mail security and SPF checks are public. Create a My NovaMX account when you want to register a domain, order hosting or MailControl.
Will the tool fix my DNS for me?
No. The tools only report what is published today. You change DNS at your current provider, or you manage DNS in My NovaMX after you move or verify the domain.
How do these checks relate to MailControl?
The free checks are a snapshot. MailControl adds ongoing DMARC reporting, SPF flattening and guided enforcement when you want continuous monitoring.
