The best MXToolbox alternatives for email health and deliverability
MXToolbox is difficult to replace with one like-for-like product because its value comes from breadth: DNS, SMTP, blacklist, and email-delivery diagnostics plus monitoring and Delivery Center. The right alternative depends on which part you actually use. These options prioritize different jobs rather than copying the entire toolbox.

Alternatives at a glance
| Product | Best when your priority is | Tradeoff to evaluate |
|---|---|---|
| HealthCheck Email | Plain-English domain health, guided fixes, and client-ready monitoring | Less focused on being a universal infrastructure lookup console |
| EasyDMARC | Broader managed SPF/DKIM and authentication services | May be more platform than a simple scanner user needs |
| dmarcian | Enterprise DMARC governance, discovery, APIs, SSO, and deep analysis | Enterprise depth may add cost and operational complexity |
| PowerDMARC | Security-suite and MSP/MSSP reseller requirements | Evaluate service breadth and plan packaging carefully |
| GlockApps | Inbox-placement and campaign deliverability testing | Different primary job from DNS/SMTP diagnostic breadth |
Best for understandable ongoing health: HealthCheck Email
Choose HealthCheck Email when the problem is not a lack of raw tests but a lack of an actionable conclusion. It combines a domain grade, ordered fixes, daily record checks, DMARC source analytics, change alerts, and focused public tools. Agencies can use the same readable model across client domains.
It is the closest fit for users searching for ‘MXToolbox, but simpler and continuously explained.’ Read the detailed HealthCheck Email vs MXToolbox comparison.
Best for managed authentication: EasyDMARC
EasyDMARC is a stronger candidate when you specifically want managed SPF, managed DKIM, reputation monitoring, and optional expert-led deployment in one authentication platform. It is less about recreating every MXToolbox lookup and more about owning the authentication program.
Best for enterprise governance: dmarcian
dmarcian is aimed at organizations that need source-level investigation, automatic domain discovery, advanced alerts, SSO, APIs, webhooks, subdomain management, and security-team workflows. It is a strategic alternative to Delivery Center rather than a replacement for every free lookup.
Best for reseller or inbox-placement needs
PowerDMARC deserves evaluation when an MSP/MSSP needs a white-label reseller model and a broader hosted-security suite. GlockApps deserves evaluation when the real requirement is seeing whether campaigns land in Gmail, Outlook, and other inboxes rather than diagnosing DNS and SMTP infrastructure.
