- You have more than 4 domains and want a published price. Above Express, every OnDMARC plan is Contact us; Unspam is $6 per domain per month for up to 500 domains
- You want an API without a sales call. OnDMARC's API starts at Essentials, which is quote-only; Unspam's REST API and MCP server come with the Custom plan
- You want to keep your DNS as it is: Unspam needs one record and leaves your policy unchanged, where OnDMARC's hosting works by NS delegation
- You also test campaigns before sending: spam score, seed-list inbox placement across 7 providers and client previews
A Red Sift OnDMARC alternative priced per domain, with pre-send testing in the same account
Red Sift OnDMARC is a DMARC platform that reads aggregate reports, hosts DMARC, DKIM and MTA-STS through NS delegation, flattens SPF with Dynamic SPF, and guides domains from p=none to enforcement. Its only published price is Express at $9/mo billed annually ($12 billed monthly) for up to 4 domains, 1 million emails a month and 30 days of history; every larger plan is quote-only, and forensic reports, the API and alerts start above Express. Unspam reads DMARC aggregate reports on its Custom plan at $6 per domain per month, first domain included, names each sending source and lists what blocks p=reject. OnDMARC hosts the records and goes further into BIMI and security tooling; Unspam adds pre-send spam, inbox placement and preview testing, with its API and MCP server on the same self-serve plan.

Which one fits you?
- You manage up to 4 domains on a budget. Express is $9/mo billed annually for 4 domains and 1 million emails a month, less than Unspam's $18/mo for 4 domains
- You want hosted records: DMARC, DKIM and MTA-STS through Dynamic Services, and Dynamic SPF flattening with unlimited lookups on Essentials and up. Unspam hosts nothing
- You need forensic reports, Smart alerts by email or Slack, SIEM streaming through Event Hub, a mark certificate included on Enterprise, or an MSP program with native multi-tenancy
Why teams move from Red Sift OnDMARC to Unspam.
A published price beyond 4 domains
OnDMARC publishes one price, Express at $9/mo billed annually for up to 4 domains and 30 days of history. Essentials, Enterprise and Premier are all Contact us. Unspam is $6 per domain per month with the first domain included, so 10 domains cost $54/mo, bought online, with a 15% discount for annual billing.
The API on the plan you buy online
Forensic reports, the API and Smart alerts are all excluded from Express. Unspam's REST API and MCP server come with its Custom plan, along with a per-domain readiness check that lists what still blocks p=quarantine or p=reject and explains why each failing source fails.
Testing a message, not only its authentication
OnDMARC Investigate gives you an address to send one email to and checks its SPF, DKIM, DMARC and TLS. Unspam tests the message itself: spam score, seed-list inbox placement across Gmail, Outlook, Yahoo, Zoho, ProtonMail, AOL and GMX, client previews and an AI attention heatmap, with a free plan and no card.
