Validity Engage Reviews & Product Details

Validity Engage is an AI-native platform built for high-volume enterprise marketing teams that want every email to be better than the last. It covers the full email lifecycle: competitor intelligence, contact validation, design and testing, deliverability, and live email monitoring. Engage unifies capabilities formerly delivered across separate Validity products: (Formerly) Validity Litmus: Broken links, brand inconsistencies, and rendering issues that slip through review erode subscriber trust. Engage's email building, QA testing, spam filter testing, and accessibility checks—backed by LLM powered spelling and grammar review—catch issues before they reach a subscriber, giving teams control without slowing production. (Formerly) Validity Everest: Unnoticed deliverability issues quietly drain revenue. Engage's inbox placement and deliverability monitoring shows exactly where your emails land across every major provider, giving teams the visibility to catch problems and stay off blocklists. (Formerly) Validity BriteVerify: Invalid contact data drives up bounces and damages sender reputation. Engage's contact and email validation keeps the data behind every send accurate—automatically. It gives teams the confidence to send at scale without second-guessing the list. Engage also adds proprietary competitor intelligence, showing you what's working across the market before a campaign even sends. Sender Certification, an upgrade available with Engage, helps senders reach more inboxes—and stay there—as a trusted sender. Engage’s insights are powered by the Validity Intelligence Network, built on 25 years of exclusive partnerships, real-time visibility into inboxes worldwide, and signals from across the email ecosystem. The network spans more than 140 ISPs, tracks 35,000-plus brands, and processes 2.5 billion behavioral data points every day. Engage puts that intelligence to work through a team of agents that watch performance around the clock, recommend the next best action, and fine-tune campaigns without waiting to be asked.

"Don't trust them / my experience"

0/5

What do you like best about Validity Engage?

Nothing, they dropped the package I liked Review collected by and hosted on G2.com.

What do you dislike about Validity Engage?

They dropped their self-service package with only 1 month's warning and no migration path except for to upgrade to their (unaffordable) enterprise package. I also didn't even realize they did this because they sent the email from their marketing domain, which I have under my email filters (rich, for an email company!) Do not trust these guys. Support is just an AI robot that tells you to buy the enterprise package. Absolute joke. Review collected by and hosted on G2.com.

"Litmus Boosts Email Marketing Precision and Efficiency"

5/5

What do you like best about Validity Engage?

Litmus has become an essential tool in my email marketing workflow. What I appreciate most is how it removes the guesswork from email testing, allowing me to preview exactly how my campaigns will appear across all devices and inboxes before hitting send. The platform’s comprehensive preview capabilities and in-depth troubleshooting tools give me confidence that my emails will render perfectly and avoid spam filters, which is crucial for maintaining high engagement rates. Beyond just visual accuracy, Litmus helps safeguard my brand’s reputation by ensuring deliverability and consistent performance. For any professional serious about email marketing precision, Litmus is a reliable, powerful solution that truly elevates the quality and effectiveness of every campaign. Review collected by and hosted on G2.com.

What do you dislike about Validity Engage?

One aspect that could be enhanced is the reporting functionality. Simplifying these features would make them more intuitive and allow for easier customization to suit the varying needs of different teams. Additionally, enabling quicker integration with a broader selection of marketing platforms would help streamline workflows even more. Review collected by and hosted on G2.com.

What problems is Validity Engage solving and how is that benefiting you?

Litmus solves the challenge of unpredictable email rendering and deliverability by offering a powerful set of testing tools and detailed analytics. It lets me preview how emails will look on different devices and email clients, which helps catch any design or technical issues before sending. This way, I can fix problems like broken links, missing images, or coding errors early on. By doing this, Litmus helps reduce the chance of emails ending up in spam or not displaying properly. That means more people actually see the emails as intended, leading to higher open and click rates. Overall, using Litmus improves the user experience and helps get a better return on investment from email campaigns by making them more effective and reliable.

"Collaboration Made Easy, Minor Pin Issue Aside"

4/5

What do you like best about Validity Engage?

I appreciate that Litmus allows me to share email content with people who may not have a Litmus license. I also value the feature that lets me highlight specific areas and indicate exactly where I suggest making edits within the content. Review collected by and hosted on G2.com.

What do you dislike about Validity Engage?

This is a minor issue, but I would prefer if a pin or comment could stay attached to the specific item it refers to. For instance, when commenting on an image, if the creator moves that image, the pin currently stays in its original position rather than moving with the image. I’m not sure if it’s technically possible to change this, but it’s a small concern compared to everything else Litmus provides. Review collected by and hosted on G2.com.

What problems is Validity Engage solving and how is that benefiting you?

Litmus has made collaborating with others incredibly easy. Before we started using Litmus, our team relied on countless emails, which often led to confusion and messages getting crossed. Now, with Litmus, our workflow is much smoother. I would be truly disappointed if we ever lost access to this tool. Review collected by and hosted on G2.com.

Thank you for taking the time to share such thoughtful feedback! We’re delighted to hear that Litmus has made collaboration smoother for your team, especially by reducing the confusion that comes with email-based reviews. It’s great to know that features like sharing with non-licensed users and pinpointing suggested edits are making a meaningful difference in your workflow.

We also appreciate you calling out the issue with comment pins not moving when an element is repositioned. While it’s a small detail, feedback like this helps us continue improving the platform in ways that matter to users. We’ve shared your note with our product team for consideration in future enhancements.

Thanks again for your kind words — we’re thrilled to be a valuable part of your process!

"Great for Email Testing, but Pricing Could Be Friendlier"

2.5/5

What do you like best about Validity Engage?

Litmus is an incredibly powerful tool for anyone working in email marketing. I really like how it allows me to preview emails across dozens of devices and email clients before sending. The design insights and spam testing features save a lot of time and reduce the risk of errors. The analytics are also very useful, especially when tracking engagement and performance at a granular level. Review collected by and hosted on G2.com.

What do you dislike about Validity Engage?

The main drawback is the price — it can be quite expensive, especially for small teams or businesses. Some features feel like they should be included in the lower-tier plans but are only available at higher price points. The interface, while clean, could also be a bit faster when switching between previews. Review collected by and hosted on G2.com.

What problems is Validity Engage solving and how is that benefiting you?

Litmus helps me ensure that every email campaign looks perfect across different devices and inboxes. It reduces the risk of broken designs, formatting issues, or emails landing in spam. This gives me more confidence in the campaigns I send and improves overall deliverability and engagement. Review collected by and hosted on G2.com.

"The Ultimate Email Cleaner!"

4.5/5

What do you like best about Validity Engage?

BriteVerify helps to identify email addresses' that are valid, invalid, and unknown. Filtering for only the valid emails, our deliverability rates for marketing emails has drastically increased. Creating lists of emails to market to, in the past we were far under expected delivery rates. After putting our lists through BriteVerify we were able to get to the 99% delivery threshold. This was huge for us because the only way we market is through email. Being able to grow our deliverability rates from under 90% up to 99% has increased our number of prospects and sales. Review collected by and hosted on G2.com.

What do you dislike about Validity Engage?

Somedays while uploading large lists, it can take multiple minutes if not longer to analyze and create the BriteVerified report. Review collected by and hosted on G2.com.

"Makes QAing Emails so Easy!"

5/5

What do you like best about Validity Engage?

Litmus has made my role at work so much easier! It has been a breeze to check emails on all different platforms on one website. I used to have to send emails from the ESP to all different email addresses and check them from my phone, tablet, and desktop. With Litmus, I have saved so much time. I also love the fact that our clients can make corrections directly in the email, letting us know what to change or fix. It's also very easy to send emails directly from the ESP to Litmus to check for spam issues! Review collected by and hosted on G2.com.

What do you dislike about Validity Engage?

We sometimes have issues where the code doesn't update the changes, but they are seen in the previews. This can be frustrating when there is a tight turnaround on a deadline, and we have to go back and forth between the two previews to see what hasn't been changed. Review collected by and hosted on G2.com.

What problems is Validity Engage solving and how is that benefiting you?

Litmus is solving the problem of checking the emails to make sure they look great across providers and platforms. Before Litmus, we had to do this manually and it just took forever. Litmus has saved me hours of time allowing me to test emails on different providers and platforms directly on Litmus! Review collected by and hosted on G2.com.

"Easy plug and play testing with your defined selection of email clients to test"

5/5

What do you like best about Validity Engage?

The length view allows you to view all your email client tests at once and zoom your browser in with full resolution. This allows me to eyeball and complete visual design/layout QA within 2 minutes, instead of opening each individual email-client test result to verify. Review collected by and hosted on G2.com.

What do you dislike about Validity Engage?

There is no automatic email folder sorting. So it can just become a big running list. Review collected by and hosted on G2.com.
