Everything you need to debug email delivery. Type what you want to check — an address, a domain, raw headers — and run it with the 250 free credits every new account starts with. No credit card required.
Email Checker
Verify a single address end to end: syntax, domain, MX, disposable flags and a real SMTP mailbox check.
Open toolEmail Syntax Checker
Validate an address against the real RFC rules — length limits, characters, quoted locals, IDN and more.
Open toolDisposable Email Checker
Spot throwaway inboxes, role addresses and free-provider domains before they hit your list.
Open toolMX Record Lookup
See a domain's mail servers, their priority and provider — and whether it can receive mail at all.
Open toolSPF Record Checker
Look up and validate a domain's SPF record — mechanisms, the 10-lookup limit and the all qualifier.
Open toolDKIM Record Checker
Check a domain's DKIM key by selector — or scan common selectors — and grade the key strength.
Open toolDMARC Record Checker
Read a domain's DMARC policy: enforcement level, coverage, reporting and alignment settings.
Open toolEmail Header Analyzer
Paste raw headers and get SPF, DKIM and DMARC results, alignment and the full delivery path.

Send to a real seed list across Gmail, Outlook, Yahoo and iCloud and see where your email actually lands.
Open toolOne account, one credit balance, every tool. Sign up once, get 250 free credits, and spend them however you like — verification, DNS and authentication checks, header analysis, or an inbox placement test.
Why are these free?
Because your first checks are on us. Every new account starts with 250 free credits — no credit card — and these tools are how most people first find out their email setup is broken: failing SPF or DMARC, missing MX records, disposable signups, dead addresses. Diagnose the problem with your free credits; when you're ready to fix it at scale — cleaning whole lists, monitoring DMARC reports, testing placement on every campaign — the same account and the same credits carry over.
