How we grade them

|---|---|---|
| Value for money | CEssential is $59 a month billed yearly ($85 monthly) for 30 spam tests and 50,000 DMARC messages a month. For DMARC alone that's above its listed rivals dmarcian ($19.99) and EasyDMARC ($35.99), but neither runs placement tests on its priced plans. | CNo plan prices were found, so there's nothing to set against the category's $23 middle. |
| Free plan and trial | BA free plan with no card: 10,000 DMARC messages a month for unlimited domains, 5 uptime monitors, 1 IP reputation monitor and 2 spam tests. A small domain can live on the DMARC side; 2 tests won't go far. | FNo self-serve sign-up, free plan or trial on the pages we read. |
| Features | CPlacement tests report inbox, spam or tab by provider, with SpamAssassin scores, authentication checks and 50+ blocklists, and DMARC reports for unlimited domains. But it doesn't clean lists or warm up inboxes; it tests and monitors only. | CInbox placement tests, reputation, authentication and blocklist monitoring and pre-send checks. It's enterprise-aimed, and the listing's name no longer matches the vendor's. |
| Ease of use | CNo App Store rating on record. A test means sending your email to its seed list, but DMARC needs a DNS record first, and the reports take some know-how to act on. | CNo store rating on record. Getting started means a demo and onboarding. |
| Platforms and integrations | CWeb only, with Google Postmaster Tools as the one connection listed, plus an API and white-label reports. No phone or desktop app. | CWeb only, with no integrations listed on the pages we read. |

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
