MXToolbox vs. DMARCeye
Weighing MXToolbox Delivery Center for DMARC, or already using their free lookups? Here is a side-by-side look at what MXToolbox and DMARCeye cover in terms of DMARC monitoring, where their pricing models diverge, and which one is best for you.
The Short Version
MXToolbox Delivery Center is a broad email deliverability suite with DMARC reporting inside it, sold per plan with a five-domain limit. DMARCeye focuses exclusively on DMARC monitoring and enforcement, sold per domain with no five-domain ceiling.
The decision depends on how much deliverability tooling you want beside DMARC, as well as how many domains you run. The two can also run side by side: Delivery Center for deliverability, DMARCeye for DMARC monitoring.
Deliverability Suite or DMARC Platform
MXToolbox bundles inbox placement testing, blacklist reputation, mailflow monitoring and complaint feedback around its DMARC reporting. DMARCeye is a dedicated DMARC monitoring platform focused on personalized guidance from monitoring to enforcement.
$129 for Five Domains or $4 / Domain
MXToolbox Delivery Center starts at $129 per month, and both paid plans list the same five-domain limit. DMARCeye costs $4 per domain per month, for up to 50 domains on Scale, with a full-featured free plan for a single domain.
Talk with Your DMARC Data
MXToolbox does not support AI analysis of your DMARC reports or MCP access. DMARCeye has an inbuilt AI assistant, as well as an MCP connector, which lets you connect your DMARC data to ChatGPT, Claude and other AI assistants.

Pricing Overview
DMARCeye charges a flat $4 per domain per month. MXToolbox prices Delivery Center per plan: $129 a month for up to 5 domains, or $399 for the Plus plan, which raises the message volume and adds SPF flattening but has the same five-domain limit.

Where Each Platform Wins
MXToolbox is broader. DMARCeye is deeper on DMARC.
Where DMARCeye Wins

✓ Built for agencies - per-client logins, white-label branding
Where MXToolbox Wins

✓ Sender reputation intelligence - 100+ blacklists, plus ASN and reputation detail on Plus
✓ Named platform integrations - Google Postmaster, Microsoft SNDS, Yahoo Feedback Loop, Validity, Mailgun + SendGrid data in one dashboard
✓ Mailflow latency - inbound + outbound
✓ SPF flattening and BIMI management - flattening on Plus
The Verdict
Both tools work well, but they're built for different teams.
Choose DMARCeye If
You want deeper DMARC monitoring capabilities with per-domain pricing and no five-domain cap: guidance from p=none to p=reject, alerts when something changes, a year of history, and an AI assistant plus MCP access to your report data. Agencies get per-client logins, white-label branding, and API access on the Agency plan.
Choose MXToolbox If
You want deliverability work and DMARC in one subscription: inbox placement testing, blacklist reputation across every sender, complaint feedback and mailflow monitoring, with DMARC reporting alongside. Five domains or fewer covers you, a 90-day window is enough history, and a suite at $129 a month fits the budget.
Frequently Asked Questions
How much does DMARC monitoring cost?
It ranges from free to enterprise pricing. Most platforms offer a free plan or a trial, and entry-level paid plans typically run from a few dollars per domain to a few tens of dollars a month. What moves the total most is the pricing model, per domain versus a plan with a domain cap versus volume-based, which decides how fast your cost grows as you add domains. See the pricing breakdown above for how the models compare.
How current are these comparisons?
Each comparison is verified against the competitor's live pricing and feature pages at the time of publication. Vendors change packaging often, so we re-check rather than rely on old data.
I'm new to DMARC. Where should I start?
If you're setting up DMARC for the first time, you don't need a tool to switch from. Start free on DMARCeye, point one DNS record at it, and the platform guides you from p=none monitoring toward p=reject enforcement at a pace that's safe for your mail. MXToolbox's free account will tell you your record sits at p=none and that your domain is at risk, then point you to Delivery Center at $129 a month for the enforcement guidance itself. On DMARCeye the AI report analyzer is part of the free plan, so the explanation of what your reports mean arrives before the upgrade rather than after it.
Is DMARCeye or MXToolbox better for agencies and MSPs?
MXToolbox does not advertise an agency tier for Delivery Center: both paid plans list a five-domain limit, and client work is pointed at MXToolbox Managed Services, a separate human-run engagement priced by quote. DMARCeye's Agency plan gives each client a separate login under your white-label branding, with pricing scaled to your client portfolio.
Is MXToolbox's free account enough for DMARC monitoring?
No, because the free account does not include DMARC reporting. It gives you one domain with weekly blacklist checks, the free SuperTool lookups, and a domain health score that flags your DMARC, SPF, BIMI and MX status in plain language. What it will not do is parse your DMARC reports or tell you how to reach enforcement: report parsing, the compliance dashboard, alerting and forensics all start on Delivery Center at $129 a month for up to five domains. DMARCeye's free plan does include DMARC monitoring for one domain, with 5,000 emails a month and 30 days of history.
Can I run MXToolbox and DMARCeye together?
Yes. The MX, blacklist and DNS lookups on mxtoolbox.com are a diagnostic reference plenty of teams use daily, whatever handles their DMARC reports. And because a DMARC record can send aggregate reports to more than one address, Delivery Center and DMARCeye can both collect for the same domain. That suits a portfolio larger than five domains: Delivery Center on your main sending domains for inbox placement and mailflow work, DMARCeye across every domain for DMARC monitoring, enforcement guidance and report history.
Who needs managed BIMI and SPF flattening?
BIMI (Brand Indicators for Message Identification) puts your logo next to your emails in inboxes like Gmail and Yahoo. Consumer-facing brands see the clearest benefit, and it only activates once your DMARC policy reaches enforcement, so it is a later milestone rather than a starting requirement. SPF flattening addresses a technical limit: SPF permits 10 DNS lookups per check, and organizations that send through many platforms can exceed that ceiling. This is a genuine MXToolbox advantage. Delivery Center manages BIMI on both paid plans and offers SPF flattening on the Plus plan, while DMARCeye lists both on its roadmap and offers a BIMI checker today. If either is a requirement now, weigh it heavily.
Who's behind DMARCeye?
DMARCeye is part of the Big Good group and runs on the same email infrastructure as Ecomail, which sends more than 1 billion emails a month for over 12,000 organizations. That deliverability background is why the platform focuses on getting domains all the way to safe enforcement, rather than only reporting on them.
