Every DMARC vendor does the same core job. They bill for it in three different ways.
All nine platforms on this page parse aggregate reports and score your posture. What separates them is what they charge you for — a domain, an email sent, or an account — and that decides your cost far more than any feature list. Grouping nine price lists into three models is a simplification; the table lower down gives each vendor’s own wording.
Tell us what you are, and we will name names.
Including the cases where the answer is not us. A shortlist of one is not a shortlist.
Almost any tool on this page will do the job. Optimize for what is included, not what is possible.
At this size the feature ceiling is irrelevant — you will use monitoring, a security score and eventually hosted MTA-STS. The question is which tier includes that third thing, because it is where the price gap opens up.
Signing up for a volume-priced plan because the entry price is $8. Check what a single large campaign does to that number before you commit.
Three billing models, three different risks.
Per-domain pricing is predictable but penalizes large estates of quiet domains. Volume pricing looks cheap until a campaign goes out. Account-level and negotiated pricing buys you support you cannot get from a price list, at the cost of being unable to compare. None is universally right — but you should know which one you are signing.
You pay for domains, whatever you send.
Predictable, and the model that survives a marketing campaign without a surprise invoice. The weakness is a large estate of parked or low-traffic domains, where you pay the same for a domain sending nothing as one sending millions.
You pay for volume, whatever your domain count.
Cheap while you are small, and the cheapest entry point on this page. The risk is that your bill is coupled to your marketing calendar, not your infrastructure: one large send can move you a tier, and monitoring cost should not scale with sending volume.
You pay for a relationship, not a unit.
Here the unit is a bundle or a contract, not the domain. One of these publishes a figure, for a five-domain bundle; the other three publish no price for any paid tier. Often justified at genuine enterprise scale — the cost is that you cannot compare like for like, and cannot evaluate without entering a sales process.
One requirement rules us out, and it is cheaper for you to know now.
The whole market at a glance.
Starting prices are the lowest published paid tier, verified October 2026 where the vendor publishes a ladder; they usually assume annual billing, and they are not like-for-like on domain count or volume. Follow a row through for the detail. If a figure here is out of date, tell us and we will correct it.
Head to head, without us
Shortlist two, then run both.
DMARC allows more than one report address, so you can point the same domain at two platforms and compare real data for two weeks. It is the only evaluation method that cannot be marketed at you.
How we compare
Every price and feature attributed to another vendor here comes from that vendor’s own published materials, checked October 2026. Where we could not find a capability in a vendor’s public materials, we say “not documented” — that is a statement about our search, not about their product. “Our pick” and any ranking are our opinion for the buyer profile named beside it, not a neutral result. If a fact here is wrong or out of date, write to hello@ddmarc.com with the page URL, and we will check it against the source and correct the page within five business days.
