Free DMARC Weekly Digests by Postmark is designed for simplicity, offering a straightforward approach to DMARC monitoring. We receive weekly email digests that summarize DMARC activity for our domains. This service provides basic visibility, showing us the top 10 mail sources and up to 5 IP addresses for each source.
While it serves as a convenient entry point for DMARC, its feature set is deliberately limited. We don't get a web dashboard or detailed real-time analytics. Recommendations for improving DMARC compliance are provided via email, which means a less interactive experience compared to dedicated platforms.
ELK DMARC, being an open-source, self-hosted solution, offers an extensive and highly customizable feature set. It leverages the powerful ELK stack (Elasticsearch, Logstash, Kibana) to ingest, parse, and visualize DMARC RUA and RUF reports. This means we have full control over our data and how it's presented.
The strength of ELK DMARC lies in its flexibility. We can create custom dashboards, build intricate query filters, and set up bespoke alerts based on any DMARC data point. This level of detail and customization is unparalleled among free solutions, but it comes with the inherent complexity of managing the underlying ELK infrastructure.

User experience

Setting up Free DMARC Weekly Digests by Postmark is remarkably simple. We only need to configure our DMARC record to send RUA reports to Postmark's designated address. After that, the system automatically processes the reports and sends us the weekly digest emails. There's no separate portal or dashboard to navigate.
The user experience is minimalistic, focusing purely on delivery of information via email. For those who prefer a 'set it and forget it' approach and only need a high-level overview of their DMARC compliance, this is an excellent fit. However, if we need to dig into specific reports or actively manage DMARC policies, this passive approach can feel limiting.
ELK DMARC's user experience is a double-edged sword. While the Kibana dashboards, once configured, can be incredibly insightful and intuitive, the initial setup and ongoing maintenance require significant technical expertise. We need to be comfortable with Docker, Elasticsearch, Logstash, and Kibana to get it up and running.
For users with the necessary skill set, the experience is empowering. We can slice and dice our DMARC data in countless ways, building custom visualizations and reports tailored to our exact needs. However, for those without this technical background, the learning curve is steep, and it can be a challenging endeavor to get value from the solution.
Which product has the best support

Support

First comparison imageSecond comparison image
For the Free DMARC Weekly Digests by Postmark, support is primarily self-service through their extensive knowledge base and documentation. As a free offering, direct one-on-one support is not typically provided, which is understandable. This means we're expected to find answers to our questions through existing resources.
If we encounter issues or have questions about interpreting our weekly digests, we'd generally rely on community forums or our own understanding of DMARC. This aligns with the 'free' nature of the service, where users manage most aspects independently. For more involved support, users would need to consider their paid DMARC offering or external consultation.
ELK DMARC, being an open-source project, relies heavily on community support. We find assistance through its GitHub repository, where we can report issues, suggest features, and sometimes receive help from the maintainers or other users. The quality and speed of support can vary significantly based on community engagement.
There's no dedicated support team or official service level agreement (SLA) for ELK DMARC. This means that if we run into a complex problem, we might need to rely on our own expertise or pay for external consulting to resolve it. This is a common characteristic of open-source projects, offering great flexibility but requiring self-sufficiency in support.

Suitability

Logo
ELK DMARC
First comparison imageSecond comparison image
Free DMARC Weekly Digests by Postmark is best suited for small businesses (SMBs) and individuals managing a single domain who need a basic understanding of their email authentication status. It's an excellent starting point for those new to DMARC who want to dip their toes in without any financial commitment or technical overhead.
It is less suitable for Managed Service Providers (MSPs) and enterprises that require comprehensive, real-time DMARC visibility, active policy management, or multi-domain support. The limited data retention, lack of a web dashboard, and high-level summaries would not meet the demands of complex email environments.
ELK DMARC is ideal for technically proficient organizations, enterprises with existing IT infrastructure, or MSPs who have the resources and expertise to deploy and manage a self-hosted solution. It's particularly appealing to those who value data privacy, full control over their DMARC data, and the ability to customize their monitoring extensively.
It is generally not suitable for SMBs or individuals without a strong technical background or dedicated IT resources. The overhead of setting up and maintaining the ELK stack, coupled with the need for ongoing system administration, makes it impractical for users who prefer a managed, out-of-the-box DMARC reporting service.

Drawbacks and what to watch out for

Free DMARC Weekly Digests by Postmark, while excellent for basic needs, comes with notable limitations, particularly its lack of a comprehensive dashboard and limited data visibility. This makes it challenging for us to perform in-depth analysis or quickly respond to emerging threats. ELK DMARC, on the other hand, demands significant technical prowess and ongoing maintenance, making it less accessible for those without dedicated IT resources.
We have pulled the average ratings from G2 for each product, and also included the most recent negative reviews for each product in full. Positive reviews tend to have less detail and have a higher chance of being fraudulent, so negative reviews are a better signal for your decision.

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.
