- 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 reads aggregate reports, hosts records through NS delegation and guides domains to enforcement. Unspam charges $6 per domain per month, first domain included, lists what blocks p=reject and adds pre-send testing.
Compared from public pricing and product pages, November 2026.
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, SPF, DKIM, MTA-STS, TLS-RPT and BIMI through Dynamic Services, with Dynamic SPF flattening past the 10-lookup limit 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
Red Sift's free Investigate tool gives you an address to send one email to and checks its SPF, DKIM, DMARC, BIMI, MTA-STS 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 email verification for single addresses and whole lists, with a free plan and no card.
Priced by domain, not by mail volume
OnDMARC sizes its tiers partly by mail volume: Express covers up to 1 million emails a month, and the trial projects your yearly volume before suggesting a tier. Unspam charges $6 per domain per month, first domain free, so the price follows the number of domains you add, and you can read the bill before you sign up.

Trying Unspam alongside Red Sift OnDMARC
-
Add your domain
Enter it in DMARC Reports. The first domain is free on the Custom plan, and Unspam generates the record to publish or adds its reporting address to the record you already have.
-
Publish one DNS record
Paste the value at your DNS provider. Your mail flow and your policy do not change, and every other report recipient in the record is kept.
-
Read your first reports
Unspam verifies the domain once the record is live. Mailbox providers usually send their first aggregate reports 24 to 48 hours after that.
Unspam vs Red Sift OnDMARC, answered.
Is Unspam a replacement for Red Sift OnDMARC?
For aggregate reporting and the road to p=reject, it can be. Unspam's DMARC monitoring reads aggregate reports, names sending sources and checks each domain's readiness for p=quarantine and p=reject. It does not host DMARC, SPF, DKIM, BIMI or MTA-STS records, process forensic reports or send alerts. If you rely on OnDMARC's Dynamic Services, keep it.
What does OnDMARC do that Unspam doesn't?
Record hosting through NS delegation for DMARC, DKIM and MTA-STS, Dynamic SPF flattening (unlimited lookups from Essentials), BIMI management with a mark certificate included on Enterprise and Premier, forensic reports and Smart alerts from Essentials, SIEM streaming through Event Hub, and a multi-tenant MSP program. Its entry plan, Express, also costs less than Unspam for 4 domains.
How do the prices compare?
For 4 domains, Unspam is $18/mo ($6 x 3 after the free first domain) and OnDMARC Express is $9/mo billed annually or $12 billed monthly, with 30 days of history and no forensic reports, API or alerts. For 10 domains, Unspam is $54/mo; OnDMARC needs Essentials or higher, which is priced on request. See pricing.
How do I move DMARC reports from OnDMARC to Unspam?
Add Unspam's reporting address to the rua tag of your DMARC record. If OnDMARC hosts the record through Dynamic Services, make the change there; otherwise Unspam can add it to your existing record without changing your policy. A rua tag can list more than one address, so you can run both during the switch, but some receivers honor only the first two, so keep Unspam's among them. First reports usually arrive 24 to 48 hours after verification.
Does OnDMARC have a free plan or trial?
No free plan. Every OnDMARC tier starts with a 14-day free trial that needs no credit card, and Red Sift's free Investigate tool checks the authentication of one email. Unspam has no trial clock: the Free plan includes 5 spam tests and 3 inbox placements a month with no card, and DMARC monitoring is on the Custom plan, from a $5 monthly minimum, with the first domain free.
Does Unspam replace OnDMARC's Dynamic SPF?
No. Dynamic SPF serves your SPF through one dynamic include and flattens it to stay under the 10-lookup limit, and Unspam hosts no records. Unspam's free SPF checker walks your record and counts its DNS lookups, so you can see whether you are near the limit, but trimming includes stays a DNS edit you make yourself. If you depend on flattening, keep it.
