Postmark DMARC alternative

A Postmark DMARC Alternative That Acts on the Weekly Digest

Postmark's DMARC digests are free, with a $14 per domain monthly plan for full data and a dashboard (October 2026). They are one of the nicest ways to see your reports. Seeing them is the first half. Fixing what they show is the other half, and it is ours.

With Cascadia you get

  • The fixes, not just the digest
  • Every sender found first
  • DKIM for every sender
  • SPF kept under its limit
  • Enforcement when it is safe
  • Monthly, cancel any time

What Ships in the Standard Plan Here

Postmark's digests summarize your DMARC reports by email, with a dashboard and 60 days of history on the paid plan. Changing SPF, DKIM, or the DMARC policy is left to you.

  • Every service that sends as you, found before anything is published
  • One SPF record, kept inside its lookup limit
  • DKIM signing set up for each sender, keys published by us
  • DMARC moved to quarantine, then reject, once your real mail passes
  • Reports gathered, parsed, and read for you every week
  • Every published record and DKIM selector checked daily
  • Unauthorized senders using your domain, surfaced to you
  • Alignment problems explained in plain words
  • 90 days of history, day by day
  • A monthly report written for people, not for a dashboard

Where Cascadia Goes Further

A digest is a good start, and we would recommend Postmark's to anyone who just wants to see. We are what comes after seeing.

We Change the Records

When a sender fails, we set up DKIM for it, correct SPF, and publish both in your DNS. A digest can only point at the problem.

DMARC Gets to Reject

Monitoring forever is the most common DMARC setting there is. We move it to quarantine and reject once your real mail passes.

Every Sender Is Accounted For

The free digest lists your top ten sources. We find every service that sends as you, including the small one nobody remembers.

Records Are Watched Daily

Every published record and DKIM selector is checked each day, and a ticket names anything that changed.

Who This Comparison Is For

The Free Digest Is Genuinely Useful

Top ten sources, five IPs each, every week, with no dashboard to visit. For a personal domain it may be all you need.

The Paid Plan Costs Less Than Ours

At $14 per domain monthly, Postmark's premium digests are cheaper than us, and you can cancel any time.

Seeing Is Not Fixing

Both Postmark plans report. Neither publishes a record or moves a policy for you.

Choose Postmark DMARC if

  • You only want to see what your reports say
  • A free weekly digest is enough
  • Someone on your side can make the fixes

Choose Cascadia if

  • You read the digest and do not know what to change
  • Your policy has sat at none for too long
  • You want every sender found and signed

Still have a question?

What is a Postmark DMARC alternative?

Any other way to read your DMARC reports, such as dmarcian, DMARCLY, or EasyDMARC, or a managed service like ours that also acts on them.

How is Cascadia different from Postmark DMARC?

Postmark summarizes your reports. We read them, fix the records, and move the policy. If you only want to see what is happening, Postmark's digests are excellent.

Is Postmark DMARC free?

The weekly digest is free: top ten sources with five IPs each and seven days of retention. The premium plan is $14 per domain monthly, with all sources, a dashboard, and 60 days of history (October 2026).

Is this related to Postmark's sending service?

It comes from the same company. This page is about the DMARC digests only. We compare Postmark's sending service separately under Transactional Email.

Can we keep the free digest?

Yes. It does no harm alongside us, though you would need DMARC reports routed to both.

How much history do you keep?

Ninety days, day by day. Postmark's premium plan keeps 60.

Do you need access to our website or our mailboxes?

No. We need your DNS and about ten minutes of your time to list the services you know send as you. Nothing is installed on your website and nobody here reads your mail.

Will switching break our email?

It should not, and the order of work is what keeps it that way. SPF is cleaned up and kept inside its lookup limit first, then DKIM is set up for every sender, then DMARC goes in at monitoring. Nothing is enforced until the reports show your real mail passing.

Do you send a digest too?

A weekly note on what the reports say, and a monthly report on the first Tuesday on or after the 3rd, at 11 AM Pacific.

Will I know if someone spoofs my domain?

Yes. Unauthorized senders show up in the reports, and you hear about it from us.

What if I want to leave?

It is monthly, so you stop at the end of a month. The records stay published in your DNS, because they were always on your domain and never on ours. We will tell you what is published and why, so whoever picks it up next, Postmark DMARC included, starts from a clean record rather than a guess.

Ready to act on the digest?

Twenty nine dollars a month per domain. If you also want your application mail sent and its delivery watched, Email Pro bundles Transactional Email, Email Authentication, and Deliverability Monitoring for $79 a month per domain.
