SendForensics offers a robust suite of tools extending beyond basic DMARC reporting. We found its primary strength lies in its comprehensive deliverability analysis, which includes spam tests, inbox placement, and content scoring. It aims to provide a holistic view of your email health, helping to identify potential issues before they impact your sender reputation.
Beyond DMARC, it provides insights into aspects like blocklist (or blacklist) presence, link quality, and even specific vocabulary issues within your email content that might trigger spam filters. It is designed to be a complete solution for email marketers and anyone focused on maximizing their email deliverability and ensuring messages reach the inbox.
The Splunk TA-DMARC add-on is a different beast entirely. It is not a standalone DMARC solution but an integration designed for organizations already leveraging Splunk for their security information and event management (SIEM). Its core function is to ingest DMARC aggregate reports into Splunk, allowing users to analyze DMARC data within their existing Splunk dashboards.
While it effectively brings DMARC data into a familiar Splunk environment, its feature set is inherently limited by its nature as an add-on. It lacks advanced deliverability features like SPF flattening, hosted DMARC, or BIMI support, and it does not offer the proactive email health checks found in dedicated platforms. It is more of a data connector than a comprehensive DMARC management tool.
How easy is each product to use
User experience
SendForensics generally offers an intuitive and user-friendly interface. We found it relatively easy to navigate, and the single sign-on feature is a definite plus for teams. The process of submitting emails for testing and interpreting the results is straightforward, making it accessible even for users who are not deep email deliverability experts.
However, we did encounter some minor workflow hiccups, such as occasional lag times in email rendering within the platform. While the system provides clear guidance, some users might find that mastering the nuances of optimization, like understanding why a retest yields different results, requires a bit of trial and error.
The user experience for the Splunk TA-DMARC add-on is entirely dependent on your familiarity and expertise with Splunk itself. It is not a plug-and-play solution. Configuring the add-on, setting up data inputs, and building dashboards requires a solid understanding of Splunk Query Language (SPL) and Splunk administration.
For Splunk veterans, this integration can feel seamless, as they are working within their familiar environment. However, for anyone without prior Splunk experience, the learning curve is steep. There is no dedicated, simplified DMARC-focused user interface outside of the Splunk ecosystem, meaning all interaction occurs within Splunk's native (and often complex) environment.
Which product has the best support
Support
SendForensics offers support to its users, and based on our experience and user feedback, the response times can vary. While some users report quick resolutions, others have noted that it can sometimes take a few days for a ticket to be addressed. This inconsistency can be a point of frustration for urgent issues.
In addition to direct support, SendForensics also provides a helpful guide section that can resolve many common queries. We found these resources to be quite comprehensive and useful for self-service troubleshooting, which can mitigate the impact of varying direct support response times.
Support for the Splunk TA-DMARC add-on is, frankly, non-existent. The add-on is explicitly listed as "Not Supported" and is also
archived
. This means there is no official support channel, no bug fixes, and no active development from its original creator. Any issues or troubleshooting fall entirely on the user or their organization.
This lack of support is a significant drawback. Organizations using this add-on must have internal Splunk experts capable of maintaining, troubleshooting, and potentially modifying the code themselves. This approach works for highly specialized teams with deep Splunk knowledge but is a non-starter for most others.
Who should use each product
Suitability
SendForensics is an excellent choice for businesses of all sizes, from SMBs to enterprises, that prioritize comprehensive email deliverability and DMARC enforcement. It is particularly well-suited for marketing teams, email managers, and IT departments looking for a dedicated platform to monitor and improve their email sending reputation and inbox placement.
For Managed Service Providers (MSPs), SendForensics offers multi-domain management and user quotas, making it suitable for overseeing multiple client domains. Its focus on proactive email health checks also makes it a strong contender for anyone who needs to ensure their emails consistently reach their intended recipients without landing in spam folders.
The Splunk TA-DMARC add-on is exclusively for organizations that are already deeply invested in the Splunk ecosystem and have robust internal Splunk expertise. It is a tool for Splunk administrators and security teams who want to consolidate their DMARC data within their existing SIEM for correlation with other security logs.
It is not suitable for SMBs or MSPs that do not already run Splunk, as the overhead of setting up and managing a Splunk instance solely for DMARC would be prohibitive. Due to its unsupported and archived status, it is also not recommended for organizations seeking a fully managed, dedicated DMARC solution or proactive deliverability assistance.

Drawbacks and what to watch out for
SendForensics, while powerful, can sometimes suffer from inconsistent support response times and occasional interface glitches. Some users also report a learning curve for optimizing deliverability scores. The Splunk TA-DMARC add-on, on the other hand, faces significant drawbacks due to its archived and unsupported status, requiring deep Splunk expertise and offering no external support or ongoing development.

Increase your email deliverability with Send Forensics
3.0 / 5
What do you like best about SendForensics?
Easy to use, interface is intuitive to navigate, our whole team can access and use the product with a single sign-on. There is no limit to the number of email tests you can send to Send Forensics to test, so it is not an issue to test every single campaign prior to launch to maximize deliverability.
What do you dislike about SendForensics?
Lag time has been an issue in the past - emails not rendering in Send Forensics has slowed down my work flow. Support team response has varied from a few hours to a few days to respond to a ticket. Also flags items within email template that are required by CANSPAM law, like our physical mailing address. Also can be glitchy, where previews of emails with flagged content does not render.
What problems is SendForensics solving and how is that benefiting you?
We run all our emails through Send Forensics prior to launch, to catch spammy words/copy and to improve the likelihood that our emails will reach inboxes of our customers.

SendForensics Review - How it helped us test and get to inboxes
3.5 / 5
What do you like best about SendForensics?
I like that it shows keywords that we can change flagged words to, similar words that you can update and exact content issues. I also like the live inbox placement testing. It also tells you if you should go ahead and send or make some changes and optimize.
Send Forensics has different sections that they look at - vocabulary and copywriting, coding and layout, link quality and data collection. Most of our issues fall under the vocab and copywriting/content.
The support and the guide section is also really helpful and most of the things we have questions on get answered pretty quickly there.
It also is a good price for the service that you get. We looked and did free trials for a lot of companies, and feel Send Forensics gives you a lot of what we needed for a very reasonable price.
What do you dislike about SendForensics?
You really have to learn to use it and see the correct patterns. Sometimes we will test something and change what they told us to, and when we retest we are hitting less inboxes or getting a lower deliverability than before. Lots of trial and error.
Recommendations to others considering SendForensics:
Do the free trial, test it out and make sure it works for you first. But if you want to fully see what it can do, pay the low price of $49 a month and do some testing. You will likely get some insights you were not receiving before and it'll help you out moving forward with getting into inboxes.
What problems is SendForensics solving and how is that benefiting you?
With our current mailing system, we weren't seeing inbox placement and spam score testing. So this is helping a lot by telling us whether the main providers or not would have it fall into the inbox or spam folder.
We've come to realize some words that are flagged so we can make the changes before even testing it in Send Forensics, so you do learn a pattern about how these things work. Send Forensics even goes as far as to show you your reputation, deliverability score, blacklists, errors, etc.

Valuable tool that everyone serious with email marketing should use
5.0 / 5
What do you like best about SendForensics?
SendForensics gives you a lot of information regarding your emails, without this tool you would have to use several other tools to be able to view all the information, and it would be much harder to do any real analysis of your “email health”.
What do you dislike about SendForensics?
I would like more details, especially regarding errors found in “Vocabulary & Copywriting” and “Coding & Layout”.
Recommendations to others considering SendForensics:
Run the trial and spend an hour investigating, you can quickly see if this is a tool for you.
What problems is SendForensics solving and how is that benefiting you?
Email marketing is difficult to succeed with, doesn't matter how much money we throw at it. SendForensics enables us to trim and adjust our email campaigns so that we get the maximum possible return on our investment.
It's so much faster to find out how to improve our email campaigns with SendForensics.
