04
One address per domain
Each monitored domain gets its own address, reports+token@dmarc.warmerly.com, with a 10-character token. The token lets two workspaces verify the same domain and each receive its own reports.

05
Proof of control by the record itself
A domain counts as verified only when its published DMARC record names Warmerly's address in rua, which only someone who controls the DNS can add. The app shows your current record with the address appended, never a second record, and never a change to your policy. Verification is rechecked on page load, on Check now, and every 30 minutes for domains added in the last 14 days.

06
A job every 30 minutes
The collector reads up to 200 messages per run, every 30 minutes, and unpacks plain XML, gzip and zip attachments, capping unpacked output at 10 MB because anyone can mail the address. Messages that cannot be parsed move to a Failed folder rather than being lost.

07
Kept for 90 days
Reports whose period ended more than 90 days ago are pruned. Each source IP gets a reverse DNS name when the report is stored, and a resent report inserts nothing twice.

The first report is not instant
Receivers fix a report's reporting address when their daily window opens. A domain verified at 10:00 therefore gets its first report after the next window closes, usually the next morning and sometimes the morning after. Google sends roughly 06:00 to 12:00 UTC. A domain that sent no mail that day gets none.

09
Shared provider domains are refused
Addresses at gmail.com, outlook.fr, yahoo.co.jp and similar belong to the mailbox provider, so nobody using them can publish a DMARC record. They are never suggested and the request returns an error.

Built as a free feature, not a paid product
The doc records that it was built as a lead magnet, with no sidebar item of its own. It sits under Accounts, Domains and on each mailbox's Health tab. There is no ranked fix list and no policy-change guidance across domains, which is where Folderly's product is ahead.

Metered on domains only
Usage is metered on domains, not senders, not sending platforms and not report volume.

05
Four steps from report to fix
The page lists four steps: route reports to a workspace-specific RUA address, normalise large ISP reports in the background, validate, deduplicate and store them privately per workspace, then rank what to fix by domain, source and policy.

06
No DNS automation yet
The page says there is no DNS automation in the MVP, so you add the reporting address to your record yourself, as with Warmerly.

AI insight in every paid bundle
The page says AI insight is included in every paid bundle and that custom AI prompts come only on the Custom plan. It shows Next best action examples but labels them illustrative.

What is live and what is not
The page lists as live workspace-scoped evidence, private report storage, subscription checkout, self-service plan management and a dashboard that rejects unauthenticated requests. Report intake is described as opening to production sending domains pilot by pilot, through a Request pilot button.

Forensic payloads are admin-only
Forensic payloads exist but are restricted to admins and kept out of logs. The page refers to aggregate reports, including Google aggregate reports and reports from large ISPs.

Not priced on the main pricing page
The main pricing page lists Folderly DMARC as Pilot and shows no price for it, saying availability, access and plans vary by product. The prices above are on the DMARC site only.

What Folderly does not say
We looked, and found no statement on these. That is about its published pages only, not about the product.
- A free trial
- How long reports are kept
- Where report data is stored
- The names of ISPs other than Google whose reports are handled
- Annual prices, which the page says are locked but does not list
- Refund terms for DMARC
- What the AI insight does beyond the illustrative examples
Where the sources disagree
We report each version rather than pick one.
- The dashboard figures on its DMARC page are labelled illustrative, not live customer data. We do not use them.

In practice
What it means for you.
Our reading of the facts above. Not a promise, and not the only reasonable reading.
Match the tool to the job
If you want to see who sends as your domain, free collection may be enough. If you manage dozens of client domains, a ranked fix list saves time.
Pilot means staged access
Its page says access is opening pilot by pilot, so ask whether you can join.
Eight domains
Warmerly covers up to 10 domains free. Folderly's Team plan stops at 5 domains, so 8 domains means Growth, at $199 a month. That is $2,388 over 12 months at the listed monthly price.
Forty client domains
Warmerly's cap is 10 domains per workspace. Folderly's Growth plan holds 25, so 40 domains means the Agency plan at $499 a month, or $12.48 a domain. If its 17% annual discount applies to that price, which the page does not spell out, the monthly figure would be $414.17.
What the volume limits mean
Folderly meters domains only, so a busy domain costs the same as a quiet one. Warmerly's collector reads up to 200 messages per run, 48 runs a day, so 9,600 messages a day at most.
Expect a day's wait for the first report
On Warmerly, a domain verified at 10:00 usually shows its first report the next morning. Folderly's page does not say how long a first report takes, so ask when you request a pilot.

Warmerly is the better fit if

Questions
Does Folderly have DMARC monitoring?
It has a DMARC product in pilot, priced from $19 a month for 1 domain to $499 for 100 domains (read 21 October 2026). Warmerly collects DMARC reports free for up to 10 domains per workspace, with no alerts yet.
Can I try Folderly DMARC for free?
We found no free trial on its page. Access is opening pilot by pilot.
How long does Warmerly keep DMARC reports?
90 days. Reports whose period ended more than 90 days ago are pruned. Folderly's DMARC page does not state a retention period (read 22 October 2026).
What do I change in DNS for each?
On Warmerly you add its reports address to the rua tag of your existing DMARC record, and the app shows the exact record. On Folderly you route reports to a workspace-specific RUA address, and the page says there is no DNS automation yet.
Can I use Warmerly's DMARC monitoring on a Gmail address?
No. Domains owned by mailbox providers, such as gmail.com, are refused because you cannot publish a DMARC record on them.
