DDMARC vs MxToolboxMxToolbox is not a DMARC platform, and we are not a blacklist monitor.
This is the one comparison on the site where the answer is often both. Their free lookups need no account and their Delivery Center watches deliverability; we process DMARC reports over time and host the records. The overlap is a single feature of theirs — so the useful question is which problem you have.
Free plan: 2 domains, no card, no expiry · Trial: card required, billed on day 15 unless you cancel · 14-day money-back on new paid plans
One price is a five-domain bundle with a message cap, the other is per domain.
Delivery Center is a suite bought for deliverability, with DMARC reporting inside it. Ours is a DMARC platform priced by how many domains you monitor.
At 5 domains, DDMARC is $100/mo cheaper — $1,200 a year. Their figure is a five-domain bundle with a 500,000-message cap and includes blacklist and deliverability monitoring we do not do at all. Ours is per domain and includes report history and hosted records they do not do at all.
List prices, monthly, at the stated domain count. Plans are not like for like: see the matrix for what each includes.
Four things, not thirty-seven rows.
Both products will tell you whether a DMARC record exists and what it says. That is where the overlap ends. These are the differences that decide it — and two of them are reasons to buy theirs.
Aggregate report processing over time
Turning months of RUA XML into per-sender trends you can act on is the entire product for us. For them it is a feature inside a suite bought for other reasons.
Hosted MTA-STS and BIMI records
We publish and maintain those records for you, including the certificate renewals. They monitor and diagnose, but they do not host the authentication records themselves.
A five-domain bundle versus per-domain pricing
Their $129/mo covers up to five domains and 500,000 messages, with deliverability monitoring included; ours prices by domain count with no message cap. Neither is wrong, but they are not comparable numbers, and treating them as one is how people conclude the wrong thing.
Deliverability, or authentication
If your authenticated mail is still landing in spam, DMARC reports will not tell you why and ours will not either. That is IP reputation and inbox placement, which is their home turf and not ours.
Where MxToolbox is the better buy.
If none of these is you, switching costs an afternoon and no data: DMARC reports are generated by receiving providers, so migrating is a change to one DNS record. Ask and we will do the bulk of it at no charge, including running both platforms in parallel while you decide — the offer and the details are below.

The questions that decide it.
Often both, and that is not a dodge. Their free lookups are the fastest way to answer a one-off question about MX, DNS or a blacklist, and nothing we have replaces that. We are for the ongoing job: parsing months of aggregate reports into per-sender trends, hosting the records and getting you to enforcement. Buying either one expecting the other is the actual mistake.
Yes, as one component of Delivery Center, which starts at $129/mo for up to five domains. It is a deliverability suite with DMARC inside it, not a DMARC platform, so you get the reports, but not hosted MTA-STS or BIMI records, ARC monitoring, or a policy simulator. For a team whose only job is to reach enforcement, that is a lot of price for the part you need.
The numbers are not comparable, and pretending they are would be misleading. Their $129/mo covers up to five domains and 500,000 messages and includes blacklist and deliverability monitoring we do not offer at all. Ours is per domain: free for 2, $29 for 5, $69 for 15 with hosted records. If you want both jobs done, you are buying two products.
No. The free domain checker does not query blocklists, and there is no continuous blacklist monitoring or reputation tracking today. If a domain landing on a blocklist needs to page someone, that is what MxToolbox’s Delivery Center is built for.
Yes, from Growth at $69/mo, including serving the policy endpoint and renewing its certificate. MxToolbox monitors and diagnoses records but does not host them. That is the difference between being told an endpoint is missing and having it maintained for you.
There is usually nothing to migrate, because most people are not replacing MxToolbox — they are adding DMARC depth alongside it. If you are moving DMARC reporting across, it is a change to the rua= address in one DNS record, and DMARC allows more than one so you can run both while you compare.
Run both for two weeks.
Point the same domain’s reports at both platforms — DMARC lets you send to more than one address. Two weeks of side-by-side data settles this better than any comparison table, including this one.
