# MXToolbox Alternatives: 7 Better Tools for SPF, DKIM & DMARC

\[MXToolbox\](https://mxtoolbox.com/) is one of the best-known names in DNS and email diagnostics. Its SuperTool bundles blacklist checks, MX and DNS lookups, and an SPF record reader into a single interface, which makes it a popular first stop for sysadmins troubleshooting deliverability (here's how the \[MXToolbox SPF record checker\](/spf-record-checker/mxtoolbox-spf/) reads your record). But MXToolbox is a \*\*read-only diagnostic toolbox\*\* - it tells you what your SPF record says, yet it won't fix the most common problem it surfaces: too many DNS lookups. It also leans heavily on paid monitoring plans, and its all-in-one interface can be more than a domain owner who just needs to \*\*check or repair an SPF record\*\* is looking for. If you want something more focused - especially around SPF flattening, DMARC reporting, or a cleaner free checker - here are seven MXToolbox alternatives worth considering. ## AutoSPF \[AutoSPF\](/) is the only tool on this list built specifically to \*\*solve\*\* the "too many DNS lookups" PermError, not just report it. Its automatic SPF flattening service replaces the domains in your SPF record with their underlying IP addresses and keeps them updated as your providers change, so your record stays valid and under the 10-lookup limit without manual maintenance. Alongside flattening, AutoSPF offers a suite of free, no-signup tools: a \[free SPF checker\](/tools/spf-checker/) that expands every include and counts your DNS lookups, an \[SPF lookup tool\](/tools/spf-record-lookup/) for tracing the full include chain, and an \[SPF record generator\](/tools/spf-record-generator/) that builds a valid record from your list of senders. If you are still on the fence about the approach, we debunk the common \[SPF flattening myths\](/spf-flattening-myths/) in a separate guide. For anyone whose main reason for opening MXToolbox is an SPF problem, AutoSPF is the more direct - and more permanent - fix. ## EasyDMARC \[EasyDMARC\](https://easydmarc.com/) is a full DMARC deployment and monitoring platform serving 45,000+ businesses. It pairs human-friendly aggregate reporting with managed SPF and DKIM, making it a strong fit for mid-sized to large organizations that want a guided path to \*\*p=reject\*\* enforcement rather than a one-off lookup. Free tools plus tiered paid plans make it easy to start small and scale. ## PowerDMARC \[PowerDMARC\](https://powerdmarc.com/) offers around-the-clock DMARC monitoring with hosted SPF, DKIM, MTA-STS, and BIMI, trusted by enterprises and governments worldwide. Its Power Toolbox covers the same record checks MXToolbox does, but within a platform geared toward \*\*ongoing enforcement and real-time spoofing alerts\*\* rather than ad-hoc diagnostics. ## DMARC Report \[DMARCReport\](https://dmarcreport.com/) is a lightweight, accessible alternative focused on making DMARC reporting simple and actionable. Instead of raw XML, it surfaces clear insights about which senders use your domain and whether they pass authentication, and it bundles handy \[SPF\](https://dmarcreport.com/tools/spf-checker/) and DKIM lookup tools. It's a practical choice for small-to-mid businesses that want visibility without complex configuration. ## dmarcian \[dmarcian\](https://dmarcian.com/) takes a project-based, education-first approach to DMARC, with a well-known free tool set: domain checker, DMARC inspector, SPF surveyor, and DKIM tools. It's a good fit for teams that want to \*\*build in-house expertise\*\* while moving to enforcement, with pricing tiers from a free personal plan up to enterprise. ## Valimail \[Valimail\](https://www.valimail.com/) emphasizes automated DMARC enforcement - it reports that over 80% of customer domains reach strict enforcement - and provides inbound and outbound protection. Its Align product helps domains meet \[Google and Yahoo's sender requirements\](/blog/ushering-a-new-era-of-security-google-and-yahoos-take-on-email-authentication/) without manual record wrangling, which suits organizations prioritizing hands-off compliance. ## MailHardener \[MailHardener\](https://www.mailhardener.com/) is an email-hardening suite with a self-learning algorithm designed to filter forwarding services from genuine unauthorized senders, reducing false positives. Its free tools include an MX inspector, SPF validator, DKIM validator, and DMARC validator, with paid plans aimed at growing teams and MSPs. ## Which MXToolbox alternative is right for you? If your goal is \*\*DMARC monitoring and enforcement\*\*, EasyDMARC, PowerDMARC, dmarcian, Valimail, or DMARCReport will take you further than MXToolbox's diagnostics - and if Mimecast's own analyzer is what brought you here, compare it against these \[Mimecast alternatives\](/mimecast-alternatives/) too. If the issue that keeps sending you back to MXToolbox is your \*\*SPF record itself\*\* - a PermError, too many DNS lookups, or syntax you can't get right - AutoSPF is the alternative built to fix it automatically. ## Fix Your SPF Record, Free Give us a test drive for \*\*30 days at no cost\*\*.
