Best free SPF and DMARC checkers
Four of the five tools in this roundup — AdminKit, MxToolbox, EasyDMARC (90,000 customers across 130+ countries, easydmarc.com, read 2026-10-23) and dmarcian — run a free, no-account SPF/DMARC/DKIM checker today; intoDNS is included for completeness even though its own report covers general DNS/mail-server health, not a dedicated SPF/DMARC check.
What’s actually free, sourced from each tool’s own page
Four of the five tools in this roundup offer a dedicated, free SPF and DMARC record checker with no stated pricing on the tool page itself: AdminKit’s SPF check and DMARC check, MxToolbox’s SPF and DMARC tools, EasyDMARC’s SPF/DMARC/DKIM checkers (per easydmarc.com, read 2026-10-23), and dmarcian’s SPF Surveyor and DMARC Inspector (per dmarcian.com, read 2026-10-23). All four also offer a free DKIM checker. AdminKit additionally has a dedicated DKIM check tool.
intoDNS is included in this roundup for completeness since it’s a well-known free DNS diagnostic site, but its own report output covers DNS delegation, nameserver health, SOA, MX and A records — not a dedicated SPF or DMARC check. It earns a place here as a general DNS/mail health report, not as a peer SPF/DMARC checker, and this page states that distinction rather than listing it as if it matched the others’ feature set.
Where EasyDMARC and dmarcian go further
EasyDMARC and dmarcian both run paid, dedicated DMARC-management platforms behind their free checkers — EasyDMARC states it serves “90,000 customers across 130+ countries” per its own homepage, and dmarcian offers a 30-day trial of its DMARC Management Platform plus professional deployment services. Those platforms are built for ongoing DMARC rollout and monitoring (reading aggregate reports over time, staged enforcement), which none of the free one-off checkers in this roundup, including AdminKit’s, currently replace.

Frequently asked questions
Is AdminKit's SPF/DMARC/DKIM check better than the others listed here?
This page doesn't rank them. AdminKit's checks are free with no account, like the others reviewed here; each tool has its own strengths (MxToolbox's broader blacklist product line, EasyDMARC's and dmarcian's dedicated DMARC-management platforms for ongoing rollout work). AdminKit is listed alongside these tools, not above them.
Does intoDNS check SPF and DMARC records?
Based on intoDNS's own report output, no — its report covers DNS delegation, nameserver health, SOA, MX and A records, not a dedicated SPF or DMARC check. It's included in this roundup by name for completeness since it's a well-known free DNS/mail health tool, but its table rows here are marked as not applicable rather than claiming a feature it doesn't have.
Do any of these require a sign-up to see a result?
AdminKit's SPF, DMARC and DKIM checks require no account. For MxToolbox, EasyDMARC and dmarcian, their own tool pages don't clearly state a sign-up requirement for a single lookup, so this page marks that specific point as unverified rather than asserting one way or the other.
Does this page use any competitor's logo or brand assets?
No. Every name here is used only to identify and compare publicly available tools (nominative use). AdminKit is not affiliated with or endorsed by any of them.
