Postmark's DMARC digest (from ActiveCampaign) is one of the simplest tools in the market — a plain weekly email, no dashboard to learn. Here's exactly what it covers, its limits, and how DMARCKeeper differs.
Postmark's paid tier is $14/month per domain; a free weekly digest is also available directly at dmarc.postmarkapp.com.
The free digest shows your top 10 sending sources and 7 days of history; the paid tier is a plain RUA report viewer with 60 days of history and team accounts.
It doesn't process RUF, TLS-RPT, MTA-STS or BIMI, and there's no hosted DMARC option.
Reports over 100,000 records are truncated, and reports over 3MB are processed as metadata only, per Postmark's own FAQ.
Alerting is a weekly (or monthly) email digest only — and if no reports arrive in a given period, the digest simply doesn't send. There's no separate notice telling you monitoring has gone quiet.

The one fact worth remembering: If your reporting pipeline breaks and reports stop arriving, Postmark's digest doesn't fail loudly — it just stops sending, with nothing flagging that monitoring has gone dark.
Where Postmark gives you one weekly email and stops there, DMARCKeeper adds a free instant checker with plain-English fixes on top of monitoring.

If you already send transactional email through Postmark and want the simplest possible free weekly glance at your DMARC reports — no dashboard, no setup beyond your existing rua= address — the free digest is a genuinely low-friction starting point.
We built it from Postmark DMARC Digests's own pricing pages and public reviews, cited inline with the date we checked (2026-07-14). Where Postmark DMARC Digests does something better, the “When Postmark DMARC Digests is the better choice” section above says so directly.
Everything above was verified 2026-07-14 directly from the vendor's own site. Pricing and features change without notice — the source link above always points to the current page.
Yes. DMARC configuration lives in your domain's DNS, not inside a vendor's account — switching your rua= reporting address is a one-line DNS change either way.
