Free DMARC Weekly Digests by Postmark is a straightforward offering focused on foundational DMARC reporting. It provides visibility into your domain's DMARC activity through weekly email summaries.
The service will identify your top 10 mail sources, showing up to five IP addresses for each. This gives you a snapshot of who is sending mail on your behalf, which is crucial for identifying legitimate senders and potential unauthorized activity. However, it lacks an interactive dashboard, relying solely on these periodic email reports for data consumption.
KDmarc, on the other hand, offers a more comprehensive suite for DMARC management. While specific feature details aren't publicly listed in detail, tools like KDmarc typically provide a full DMARC reporting dashboard where you can analyze trends, identify all sending sources, and track authentication rates.
We expect to see capabilities for in-depth source detection, including detailed breakdowns of authentication failures and passes. Such platforms often include features like forward detection to help distinguish legitimate forwarding from spoofing attempts, along with robust reporting options that go beyond simple weekly summaries.
How easy is each product to use

User experience

LogoLogo
First comparison imageSecond comparison image
The user experience for Free DMARC Weekly Digests by Postmark is decidedly minimalist. Once you've set up the DMARC record to point to Postmark's collection address, the interaction is almost entirely passive. You receive weekly email digests, which are clear and easy to understand, providing the essential data without overwhelming you.
This simplicity is both a strength and a limitation. For those who prefer a 'set it and forget it' approach, it's perfect. There's no dashboard to navigate, no complex filters to apply, just a digest. However, if you need to drill down into specific data points or troubleshoot an issue, the lack of an interactive interface means you're out of luck, waiting for the next weekly report to confirm changes.
For KDmarc, we would anticipate a more traditional, dashboard-driven user experience. Such platforms typically offer a centralized web interface where users can log in to view aggregated DMARC reports, configure settings, and manage their domains.
While lacking specific details, a typical DMARC reporting tool aims for an intuitive dashboard with visualizations to simplify complex data, allowing users to quickly identify authentication issues and unauthorized senders. This approach caters to users who need a more active role in monitoring and managing their DMARC compliance, offering greater control and real-time insights compared to email-only reports.
Which product has the best support

Support

Free DMARC Weekly Digests by Postmark benefits from being part of the larger Postmark ecosystem, which is known for its excellent support for its primary transactional email service. While direct support specific to the free DMARC digests might be more limited than for paid products, the underlying knowledge base and general customer service channels of Postmark are accessible.
For a free service, the support is primarily self-service through documentation and community forums. If you encounter issues with DMARC record setup or understanding the weekly digests, you can often find answers through Postmark's comprehensive guides and articles, or by contacting their general support for broader email deliverability questions. However, don't expect dedicated DMARC specialists for a free product.
Since KDmarc is a dedicated DMARC reporting platform, we would anticipate more specialized support focused directly on DMARC implementation, analysis, and troubleshooting. Dedicated DMARC providers usually offer various support channels, which may include email, live chat, or even phone support for higher-tier plans.
Typically, such services provide extensive documentation, FAQs, and sometimes guided setup processes to help users configure DMARC correctly. The expectation for a paid DMARC tool is a more proactive and hands-on support experience, particularly for complex scenarios or large-scale deployments, helping users understand their DMARC data and achieve enforcement.
Who should use each product

Suitability

LogoLogo
First comparison imageSecond comparison image
Free DMARC Weekly Digests by Postmark is ideal for individuals or small businesses (SMBs) with a single domain or limited email sending volume who need basic DMARC monitoring without any cost. It's a great entry point for those new to DMARC, providing fundamental insights into their email authentication.
For Managed Service Providers (MSPs) or enterprise-level organizations, this free offering is likely too basic. It lacks the centralized management, detailed reporting, and real-time visibility required to manage multiple client domains or high-volume sending. Its utility for enterprise is minimal, only serving as a very rudimentary check for non-critical domains.
KDmarc, as a dedicated DMARC platform, is likely suitable for a broader range of users, from growing SMBs to large enterprises and MSPs. Its expected comprehensive features and reporting capabilities would appeal to organizations that require detailed visibility, active management, and enforcement of their DMARC policies.
MSPs would likely benefit from multi-tenancy features and centralized dashboards to manage DMARC for numerous clients, while enterprises would appreciate advanced analytics, alert systems, and possibly integrations for robust email security. Small businesses with more complex sending infrastructures would also find its detailed insights more valuable than a basic digest.

Drawbacks and what to watch out for

Free DMARC Weekly Digests by Postmark, while excellent for its price point (free!), naturally has limitations. Its primary drawback is the lack of a real-time, interactive dashboard, which means less immediate visibility and harder troubleshooting. The scope of data is also limited to top sources, which might not be enough for complex environments. KDmarc, without specific public details, faces the challenge of justifying its potentially higher cost against its feature set. If it doesn't offer sufficiently advanced analytics, ease of use, or unique features, its value proposition might be less clear compared to other comprehensive DMARC solutions.

Not the best
What do you like best about ActiveCampaign Postmark? It works. Their API is easy-to-use and we never experienced any downtime. What do you dislike about ActiveCampaign Postmark? The price is too high for what we get. Also their administration panel and Analytics graphs are not user friendly. Recommendations to others considering ActiveCampaign Postmark: Check Mandrill as alternative. What problems is ActiveCampaign Postmark solving and how is that benefiting you? We use Postmark as secondary provider to send emails. We send ~100M emails per week.

A clean simple api
What do you like best about ActiveCampaign Postmark? Postmark has been simple and reliable in the 2+ years I've used them. Their API has a fast response time and their batch send calls has been helpful in maintaining a quick response time on our service. They've also been generous in giving us free credits from time to time. They provide webhooks for events you are interested in e.g. bounced emails, spam reports. Their documentation is extensive and comprehensive and also includes libraries for several languages (we use them with python and php). What do you dislike about ActiveCampaign Postmark? Some of the new features Postmark has added aren't as simple as their first product, especially the email templates. Their admin interface also is weird in that it only lets you look at 30 day periods for statistics (we track our own analytics so it's less of an issue for us). Recommendations to others considering ActiveCampaign Postmark: Postmark quickly and effectively help us getting transactional email up for our service. We've evaluated switching to Mailgun (since we get it for free) however right now postmark seems to have the simpler API. What problems is ActiveCampaign Postmark solving and how is that benefiting you? Postmark helped us quickly and effectively add an outside transactional email provider instead of sending SMTP emails. It's also helped ensure that our app stays quick when we were originally directly calling it from the application thread. We've had no problem with getting marked as spam or deliverability and their open tracking by email client has been helpful. We've sent 200,000+ emails with postmark so far.

Speed at a low price
What do you like best about ActiveCampaign Postmark? I really appreciate the speed with which I receive emails. It's very important to me that customers receive emails on time because otherwise we can miss out on some business. What do you dislike about ActiveCampaign Postmark? I don't like the fact that sometimes Mustachio, which is the language used to write emails, is a bit old-fashioned and I have to find other ways to do things that could be done in a more simple way. What problems is ActiveCampaign Postmark solving and how is that benefiting you? Postmark helps me send emails to my customers and retrieve data on email opens. This allows me to have complete control and visibility over the email communications sent.

Definitely worth trying for your company - better than other options!
What do you like best about ActiveCampaign Postmark? Postmark is a really great service and gets the job done when delivering emails to our recipients. There are almost never any hiccups (i.e. emails getting blocked like some other delivery services). We're better able to provide website maintenance and hosting PLUS email delivery services, which is a great one-stop shop feature for clients. Some advice I would give to those on the fence is trying the free trial of Postmark to see if it's a good fit for your company. What do you dislike about ActiveCampaign Postmark? The price isn't as competitive as other options, which can sometimes be an issue dealing with clients. The training opportunities are also minimal if you don't know where to start, which can sometimes be an issue. The biggest dislike from a technical standpoint is there isn't an archiving option. Some clients like this feature when working with us, so that's one thing that can have us looking at other transactional email services. Recommendations to others considering ActiveCampaign Postmark: I would recommend the free trial to those considering Postmark. It's just slightly above average pricing, but is also a better option than the competitors, so overall I would recommend! What problems is ActiveCampaign Postmark solving and how is that benefiting you? We're able to use just Postmark in-house to manage transactional emails, which is a great benefit because when we need to look up something, we don't have to search through individual emails. If something were to go wrong, we can simply check with Postmark. As for our clients, we can use Postmark to deliver all the necessary emails almost always without fail, so this gives us credibility to get the job done when we say we can manage their email services.
