Litmus from Validity review from an Email Marketer

May 15, 2026

Use Cases and Deployment Scope

As an email marketing manager, I use Litmus from Validity on a daily basis. This platform allows me to send and receive proof review/approvals from cross-company stakeholders, visually see how the email will render on various email platforms, ensuring accessibility rendering and also provides the ability to easily implement pre-created modules (countdown timers, polls, satisfaction feedback, scratch-off, etc.) as an HTML code snippet into our emails.

Their deliverability and analytics tool is also a very useful aspect of the platform by providing insights reporting on read time, platform, dark mode and engagement.

Pros

Multiple platform email proofing/rendering
Creative module creation (no HTML coding required)
Engagement reporting

Cons

Ease of implementing engagement back into Salesforce
Mobile proofing ability - our team members are always on the go

Likelihood to Recommend

This is a great platform for anyone working in email marketing. The ease of using their pre-made templates, content block layouts, personalization modules and analytics reporting is a tremendous time saver. I am not an HTML coder by background, so having these pre-made modules is a life saver and enhances our email design.

Use Cases and Deployment Scope

I'm an email developer. I use Litmus more often to QA my emails. I check how my email will render on multiple devices. I also check my accessibility rating to ensure my email is inclusive and accessible to my subscribers. If I build emails from scratch, I will often use Builder to help fix any rendering issues. I build my interactive models with the help of Litmus' Personalized Content modules. Beyond QA, I also use Litmus to track deliverability and analytics for all of my emails.

Pros

Access to device renderings
Personalized Content modules
Providing insights regarding your code/content - accessibility, links, tracking, load speed, spam testing etc.
Community

Cons

I would like to be notified in the platform when new email clients for testing are made available.

Likelihood to Recommend

Proofing your emails is necessary. This is a tool that allows you to see how your email not only renders on multiple devices but how it performs. Some email building platforms will tell you their drag and drop templates are ready to go, however they stop short of analyzing accessibility, checking links, load speed among other things. I've also experienced drag and drop template issues as new email clients are released. Litmus provides peace of mind that you did your due diligence on crafting your email. While Litmus does provide some reporting you will not see every typical analytic an email report offers. However, you can use your Litmus data to enhance your email reports which in turn creates a robust view of email performance.

Use Cases and Deployment Scope

We use Litmus to proofread emails and share emails with the client. We build the emails directly in Litmus and then share the proofs with the clients for them to make edits. Litmus enables our clients to provide direct feedback on email proofs, allowing for a smooth process. It has really helped us work effectively.

Pros

Commenting on proofs
Proofing different renders across devices
Highlighting the exact spot of code when clicking a part of the email.

Cons

Sometimes the links take a while to load in the previews
I would like to be able to AB tests emails directly within one proof

Likelihood to Recommend

My entire position relies on building emails. I love that Litmus allows me to build emails directly in the platform and it makes it easy to be able to click different parts of the email to change the code. I then like being able to share the proofs with our clients and letting them comment directly within the emails to make any edits or changes.

Use Cases and Deployment Scope

Checking emails are rendering correctly across all devices and email clients

Pros

Has many device and esp options
You can easily send tests
Public links for people who don’t have Litmus

Cons

I’d like to be able to have the asset name match the platform im sending it from without having to rename manually
Sometimes it takes a little while / refreshing before you can see your email
An easier way to update a new version of an email text

Likelihood to Recommend

It’s super handy for spotting issues and giving warnings for things, like an automated qa

I like that you can select your own view of devices or esps

Use Cases and Deployment Scope

We use Litmus as the ultimate stop for QA. Everytime we send an email we make sure that it works in all ESPs both in light and dark mode. Litmus makes it a one click process which saves us hours of time while giving us the peace of mind that everything will look it's best to all our clients.

Pros

Allows us to preview emails in all EsP in both light and dark mode
Is extremely easy to use, basically you are one click away from QA
Litmus UI is intuitive and doesn't require much of a learning curve

Cons

I would like to have an owner of each email in the main dashboard. It's easy to get lost when a team is using it.
It would be awesome if they could use AI to flag emails that do not look good or have accessibility issues

Likelihood to Recommend

I believe that any time you want to test a new layout Litmus should be used to make sure the front end looks just right, specially for testing dark mode. I tend to skip it when I'm using an email template that has been tested multiple times. I don't feel like it's necessary in those cases.

Use Cases and Deployment Scope

Litmus is an essential tool for my job. We can easily view how our email campaigns will render across all of the different email platforms, browsers, and devices. Litmus allows us to ensure that every aspect of our emails is taken care of before we press send and after. Litmus has enabled us to feel more confident in our work through checking accessibility of our emails to seeing the analytics post-send.

Pros

QA of email campaigns
Monitoring emails
Providing analytics

Cons

It would be helpful to see more details within analytics.

Likelihood to Recommend

With email clients constantly making updates, using Litmus allows us to ensure our email campaigns are rendering correctly and without error. Recently an update was made that messed up the look of buttons in our emails and Litmus made it easy for us to quickly troubleshoot and resolve the issue.

Use Cases and Deployment Scope

In Short, I use snippets and partials; the main use case is how precise the rendering visibility we have in Litmus. It's tremendous, and the simplicity of using Litmus is just mind-blowing. So far, it is the best tool an organization can have :). So far, I don't see any negative mark using Litmus in a day-to-day scenario. Sometimes I face lag which should be resolved asap

Pros

Snippets
partials
Folder structure

Cons

Update last saved Litmus lag
Proper missing HTML Code tags finder
work o lag while saving code, sometimes when we keep tab opened for too long, saving doesn't work, so please fix that

Use Cases and Deployment Scope

I use Litmus to test our emails to see how they perform across various platforms and identify issues with accessibility and links. This allows us to test emails without having to send to personal emails or create test email addresses to use.

Pros

It is simple and easy to send test emails to Litmus.
It is easy to learn and teach the basics of Litmus.
The Q and A functionality is intuitive to navigate.

Cons

For a few of the accessibility issues when they are identified, it can be hard to tell what it means by the issue.

Likelihood to Recommend

it is well suited for those like myself who work in email marketing and communications to test and review emails for quality and functionality as well as provide a tool to strengthen accessibility of emails.
