FAQ
Common questions
Everything you need to know before running your first infrastructure audit.
What tools does FeedPipeline offer? +
Today we offer a DNS & deliverability domain checker (SPF, DKIM, DMARC, MX, blocklists) and a disposable email detector with bulk support. More tools are on the roadmap.
Do I need an account? +
Core tools work without signing up. We may introduce optional accounts or paid plans in the future for advanced features—free checks will remain available where possible.
Where does DNS data come from? +
Domain checks use Google Public DNS (dns.google/resolve). Results reflect what public resolvers see for your domain at lookup time.
Do you store what I check? +
Scans run client-side in your browser. We do not require an account and do not persist your lookups on our servers for the current tools.
Can I check domains or emails I do not own? +
Yes. All checks use public DNS and published blocklists—useful for agency audits, lead validation, and deliverability consulting.
Pick the right tool for the job
Audit sending domains before campaigns, or screen signups before they hit your CRM.
