❓ FAQ
Is it really free?
Yes. Free tier: 3 domains per bulk check, unlimited times. No signup, no ads, no credit card. Pro plan (€9/month) removes the 3-domain limit and adds CSV exports + API access.
How long does a bulk check take?
Typically 3-10 seconds for 3 domains. Each domain requires multiple DNS queries (MX, TXT, blacklists) which are resolved sequentially to avoid rate limiting.
What information do I get per domain?
Deliverability score (0-100), MX records count, SPF status (✅/❌), DKIM detection, DMARC configuration, blacklist hits across 5 DNSBLs, and a link to the full audit.
