Feature set

Valimail offers a comprehensive suite of DMARC enforcement and email authentication tools. We found their automated DMARC enforcement to be a standout feature, significantly reducing the manual effort typically associated with moving to a reject policy.
Their platform provides robust visibility into sending sources, identifying legitimate and suspicious senders by name. We particularly appreciated the SPF flattening and automated DKIM management, which are crucial for large, complex email ecosystems.
Postmastery's Console provides strong DMARC reporting, focusing on granular data analysis. We experienced a platform that excels in providing detailed insights into email authentication, including SPF, DKIM, and DMARC alignment status.
While their core offering is excellent for monitoring, we noted that active enforcement features like automated SPF flattening and DKIM key rotation are handled more through their consulting services rather than directly embedded in the self-service tool.
How easy is each product to use

User experience

LogoLogo
First comparison imageSecond comparison image
Valimail's interface is generally intuitive, making DMARC monitoring and management accessible. We found the dashboards to be clear, providing a good overview of email traffic and authentication status, although some users report initial confusion.
The setup process is straightforward, particularly with their guided workflows for DMARC policy changes. We did notice that navigating more advanced configurations or understanding specific failure reports sometimes required a deeper dive, but overall, it's a smooth experience.
Postmastery's Console offers a functional and data-rich user experience, especially for those accustomed to detailed email deliverability metrics. We found the reporting capabilities to be quite powerful, allowing for deep dives into specific traffic patterns.
However, compared to Valimail's more automated approach, Postmastery's interface sometimes requires a higher level of technical familiarity to fully leverage its capabilities. The focus is clearly on providing comprehensive data for expert analysis.
Which product has the best support

Support

First comparison imageSecond comparison image
Valimail provides strong customer support, particularly during onboarding. We experienced responsive and helpful interactions, with a dedicated account manager typically assigned to paid tiers. Their knowledge base is also quite extensive.
Some users have noted that certain tasks still require reaching out to support, suggesting that self-service options could be expanded in specific areas. However, for critical DMARC enforcement and troubleshooting, their team proved valuable.
Postmastery is known for its expert consulting services, which naturally extend to their support. We found their team to be highly knowledgeable in the intricacies of email deliverability and DMARC implementation.
Their support model seems to be more integrated with their consulting offerings, providing a hands-on, expert-driven approach. While their console is self-serviceable for reporting, for deeper issues or complex setups, their consulting expertise is a significant asset.
Who should use each product

Suitability

LogoLogo
First comparison imageSecond comparison image
Valimail is highly suitable for enterprise-level organizations with complex email environments that need automated DMARC enforcement and SPF flattening. Its comprehensive features make it ideal for those aiming for rapid DMARC reject policies.
For MSPs, Valimail offers robust tools for managing multiple client domains, though the pricing model can be a consideration. SMBs with simple needs might find the free Monitor plan useful, but the paid tiers are generally geared towards larger operations.
Postmastery is an excellent choice for organizations, particularly enterprise and mid-market, that value deep analytical insight and expert consulting alongside their DMARC reporting. Their approach is well-suited for those with internal deliverability teams or a need for bespoke solutions.
MSPs could benefit from Postmastery's expertise for complex client scenarios, leveraging their consulting services. SMBs might find their contact-for-pricing model less appealing than more transparent, tiered offerings, unless their needs are very specific and require a tailored solution.

Drawbacks and what to watch out for

Valimail, while powerful, can be expensive for advanced features and some users find the free-to-premium feature segmentation frustrating. Postmastery's main drawback is its lack of transparent pricing and a less automated, more consulting-heavy approach for some advanced features, which might not suit every organization.

Easy DMARC Monitoring But Not Great
What do you like best about Valimail? Valimail is pretty simple to setup and use. We were wanting to monitor some changes to DMARC, and Valimail was the platform we ultimately decided to use. What do you dislike about Valimail? A few things I don't like: 1. The free vs premium features are frustrating. I can't see enough value from free to validate a move to premium. 2. The Sender Requirement Failure feature is in beta and never really works. I can't only get it to work if I expand it before a week, and even then it's hit-or-miss. 3. It doesn't really do enough. Other platforms I've tried did a better job at helping to explain the WHY and HOW rather than just the what. Valimail primarily focuses on the WHAT. 4. Some of the feature organization is weird within the app, even after having used it for a few months. I can get more value in the account overview than the sender requirements failure, which is counter-intuitive IMO. What problems is Valimail solving and how is that benefiting you? We had a baselevel view of email security when I was initially hired and wanted to monitor the DMARC changes effectively.

No G2 reviews
G2 is the most popular review platform for DMARC products, so this is a strong signal that this product is not popular.
I like Valimail - mostly.
What do you like best about Valimail? Good interface for viewing DMARC reporting information. What do you dislike about Valimail? Price, it'd be nice if they could institute a model based on volume rather than the number of email domains. What problems is Valimail solving and how is that benefiting you? Valimail provides DMARC provides good aggregate reporting for our email domains, allowing us to implement to the eventual reject policy goal.

Straightforward onboarding

Some features aren't as developed as some competitors, however ultimately it's up to each organization to decide the value of those features. What problems is Valimail solving and how is that benefiting you? Being able to report on DMARC successes and failures, to help us fine-tune the configuration to ensure each domain is correctly configured.

Valimail Simplifies DMARC Management, But Watch for Vendor Lock-In
What do you like best about Valimail? My favorite thing about Valimail is having a single portal that puts all DMARC reports into an easy to understand view. Having this information allowed us to identify hundreds of 3rd party email sources sending on behalf of our domain. Doing this without such a portal would be incredibly difficult especially in a franchise setting like ours where we have more services sending on behalf of our domain than most other companies. What do you dislike about Valimail? Valimail isn't cheap but you definitely get what you pay for. I also grow concerned about vendor lock-in now that I have setup Valimail to handle DMARC, SPF and DKIM with no exist strategy. What problems is Valimail solving and how is that benefiting you? Valimail solves the problem of visibility into who is sending on our behalf and makes identifying them easy.

A Must-Have for Email Security
What do you like best about Valimail? The best thing about Valimail is its fully automation feature as we can get the reports automated with whole monthly data . As I prepare reports every month in which I have to include the malicious email data so I do not need to manually check each single thing , the Valimail does it for itself. What do you dislike about Valimail? The thing which I dislike about Valimai is that its little expensive especially for the businesses which are small nd not much expanded . What problems is Valimail solving and how is that benefiting you? The problem which Valimail is solving for me is the manual effort for exporting the data related to spam emails and its security checks are the best .It filters out the emails properly and which are suspicious , they get rejected easily .
