VendorPulse
Free DNS, Email & WHOIS Check
Check SPF, DKIM, DMARC, MTA-STS, blacklists, MX records, DNS health, and domain registration (WHOIS/RDAP) for any public domain. For monitoring, vendors, and full security tools, sign in to the dashboard.
Public lookup only. Rate limited to protect the service. Do not scan private or unauthorized targets.
Email deliverability test
Send a real email from your normal mail system (Outlook, Gmail, your website, CRM or newsletter tool) to a unique address. We show whether SPF, DKIM and DMARC passed, whether your domains are aligned, and your sending server's reputation and encryption.
Track uptime, vendors, invoices, SEO audits, and security checks in VendorPulse.
WHOIS / RDAP
VendorPulse can watch domain and SSL expiry and notify your team automatically.
