Free Business Tools
Practical utilities I built because clients kept asking the same questions — about email deliverability, SPF records, and whether their DNS was configured correctly. No jargon, no gatekeeping.
Each tool runs in your browser. Results are for guidance — if you need help fixing what they find, get in touch.
MailFlow Analyser
Scan domains for SPF, DKIM, DMARC, BIMI, MX records. Get actionable fixes for your email infrastructure.
- SPF, DKIM, DMARC
- BIMI & MX checks
- DKIM selector discovery
- MX record lookup
Network Recon
IP geolocation, VPN detection, security scoring, speed test, threat intelligence, and interactive terminal.
- IP lookup
- Geolocation map
- VPN/proxy detection
- Speed test
- Threat intel
- Data export
When to use these tools
Run MailFlow before launching a campaign or after moving email providers — it surfaces SPF, DKIM, and DMARC issues that cause mail to land in spam. Use Network Recon when a site feels slow or misconfigured and you want a quick DNS and connectivity snapshot without paying for enterprise tooling.
Need something custom for your team? I build internal tools and client portals as part of custom SaaS work.
