Email deliverability and DMARC tool pricing (2026): 11 spam testing and DMARC monitoring tools
Cold email teams pay for deliverability twice: once to test where messages land (inbox placement and spam tests) and once to keep sending domains authenticated (SPF, DKIM and DMARC monitoring). These tools price in different units, by tests per month, by domains, or by mailboxes, so the headline price is rarely like for like. This page lists the lowest published plan of every deliverability tester and DMARC tool we track, what that plan is sized by, and the full plan list from the vendor's own pricing page.
Summary: 11 of 11 tools publish a monthly entry price, from $9/mo (Red Sift OnDMARC) to $129/mo (MxToolbox); median $25/mo. 5 list a free plan. Prices verified against vendor pages, latest check .
How this page works: Sorted by lowest published entry price within each table; ties alphabetical. The entry price is the lowest price the vendor publishes (often with annual billing), "How it's charged" is read from the vendor's plan list, and each row links to the pricing page we checked. No placement here is paid. Methodology.

Do I need a deliverability tester if my cold email tool has warmup?
Warmup builds sender reputation; a placement test shows where a real campaign email lands today. Several cold email platforms include warmup but not seed-list placement tests, which is why teams pair them with a tester. Free single tests (see the free-plan sentence above) are enough to check a new domain's setup; monthly test plans suit teams that launch campaigns every week.
How are DMARC tools priced?
Mostly by the number of domains monitored or the volume of email covered by DMARC reports, with higher tiers adding hosted SPF, BIMI or managed services. Read the plan details column for the domain and volume limits before comparing entry prices, and note that several vendors show the annual price first.
Is a free DMARC record generator enough?
A generator creates the DNS record; monitoring reads the aggregate reports that mailbox providers send back, so you can see which services send as your domain before moving to p=quarantine or p=reject. Some vendors here offer a free or personal tier for small senders; paid plans add more domains, alerts and support.
