Free VPS & Email Deliverability Tools
Live lookups, not a form that emails you a report. Built because our own customers running email infrastructure needed exactly this, every day.

See your IP address, country, city and ISP instantly — or look up any other IP.
Open tool →SPF, DKIM & DMARC Checker
Enter a domain to see its real SPF and DMARC records, and check whether DKIM is configured.
Open tool →PTR / rDNS Lookup
Enter an IP address to see exactly what its reverse DNS record says right now.
Open tool →IP Blacklist Checker
Check an IPv4 address against Spamhaus, SpamCop and other major DNSBLs.
Open tool →SSH Connectivity Test
Check whether SSH is actually reachable on a server and port, confirmed by a real SSH banner.
Open tool →These tools don't require a VPS For Life account — they're free for anyone. If you're setting up email sending, Email Marketing VPS plans include a dedicated IPv4, open Port 25 and custom rDNS by default.
