Free DMARC Weekly Digests by Postmark provides a foundational DMARC reporting service. We receive weekly email digests that summarize our DMARC activity, highlighting the top 10 mail sources and up to 5 IP addresses for each. This gives us a quick overview of our email ecosystem.
While the reports are delivered via email and lack a dedicated web dashboard, they do include actionable recommendations. The focus is on simplicity and ease of use for those who prefer email-based updates without needing to log into an interface.
DMARC-SRG, as a self-hosted PHP parser and report generator, offers robust capabilities for analyzing DMARC data. Once set up, it allows us to process incoming DMARC XML reports, providing detailed insights into our email traffic, authentication results, and potential spoofing attempts.
The power of DMARC-SRG lies in its self-hostable nature, which grants us full control over our data and reporting environment. This means we can customize the reports and integrate them into our existing infrastructure, though it requires technical expertise for deployment and maintenance.

User experience

Using Free DMARC Weekly Digests is straightforward, primarily because the interaction is limited to receiving weekly email reports. There's no dashboard to navigate or complex settings to configure beyond the initial DMARC record setup. This 'set it and forget it' approach is appealing for those who prefer minimal engagement.
The email reports are designed for clarity, aiming to present essential information in an easily digestible format. However, the lack of an interactive interface means deeper data exploration, historical trend analysis beyond 7 days, or on-demand reporting is not available, which can be a limitation for some.
DMARC-SRG requires a hands-on approach from the outset. As a self-hosted solution, we need to handle the installation, configuration, and ongoing maintenance of the PHP parser and viewer. This demands technical proficiency in server management, PHP, and DMARC concepts.
Once deployed, the user experience revolves around the locally hosted interface. While functional, it might not offer the polished, intuitive feel of commercial DMARC platforms. The benefit, however, is complete control over the display and processing of DMARC data, allowing for custom views and integrations if we have the development resources.

With Free DMARC Weekly Digests, support largely comes in the form of the actionable recommendations included in the weekly email digests. For specific issues or questions related to DMARC configuration or report interpretation, Postmark generally offers customer support, although the free tier might have limited access compared to their paid services.
Our experience with Postmark's support for their broader services suggests a helpful team, but for a free product like the DMARC Weekly Digests, expectations should be tempered. The self-service documentation would be our primary resource for general DMARC queries.
DMARC-SRG, being an open-source project, primarily relies on community support and self-help. We would typically find assistance through its GitHub repository, issue trackers, and potentially user forums or online communities focused on DMARC or PHP development.
This means that direct, dedicated support from developers is not guaranteed, and resolving issues often involves our own technical expertise or contributions from the community. For organizations without in-house technical staff comfortable with open-source troubleshooting, this can be a significant hurdle.

Suitability

First comparison imageSecond comparison image
Free DMARC Weekly Digests is an excellent choice for individuals or small businesses (SMBs) with basic DMARC monitoring needs. It's suitable for those who want a simple, cost-free way to keep an eye on their domain's DMARC compliance without deep dives into data. MSPs (managed service providers) or enterprise clients would likely find its limited features insufficient for comprehensive management.
It's particularly good for single domain owners who are just starting with DMARC and prefer receiving periodic, easy-to-understand summaries directly in their inbox. It helps to flag major issues without requiring significant time investment or specialized DMARC knowledge.
DMARC-SRG is best suited for technically proficient users, small to medium-sized businesses (SMBs), or even enterprise environments that have the internal resources for self-hosting and customization. It appeals to those who prioritize data ownership and custom reporting capabilities over a managed service.
It's less suitable for MSPs looking for an out-of-the-box solution to manage multiple client domains efficiently, or for SMBs without dedicated IT staff. For enterprises with specific compliance requirements or integration needs, DMARC-SRG offers the flexibility to build a bespoke solution, provided the expertise is available.

Drawbacks and what to watch out for

While Free DMARC Weekly Digests offers a convenient entry point into DMARC monitoring, its limited report history, lack of an interactive dashboard, and restricted visibility into mail sources can hinder comprehensive analysis. DMARC-SRG, on the other hand, demands significant technical expertise for setup and ongoing management, and lacks direct support or advanced features found in managed 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.
