"A nice platform for Email previews"
What do you like best about Litmus?

I like it's QA checklist features that always display previews of your emails across multiple email client's and that always help to identify any errors or any broken links. Also I like how it always makes sure that your email is compliant with accessibility standards.

What do you dislike about Litmus?

The only problem that I have discovered while using it is that it doesn't have an image hosting server so you must use a separate server.

What problems is Litmus solving and how is that benefiting you?

It reduced my effort and time . It's also like a life saver to me since it solved all my rendering issues.

It's a must have paltform especially if you send frequent emails,so I don't have any complain towards it.

Can't think of anything at the moment,it serves me right!

"Litmus is a great emailing platforms and so useful in verifying emails for different platforms."
What do you like best about Litmus?

What I like the most is the Previews and QA option that helps verify that it's AODA approved and how it will show on different email platforms.

What do you dislike about Litmus?

If there`s one thing that I would like to have, is a recycling bin available for deleted emails as it would be a nice feature to add in case of accidentally deleting an email.

What problems is Litmus solving and how is that benefiting you?

It saves time spent approving emails with colleagues before sending them out, and I can see if the email's HTML code is not correctly written for different platforms.

"Essential for doing email marketing the right way"
What do you like best about Litmus?

The email previews are very accurate and simulate a large variety of ecosystems.

What do you dislike about Litmus?

Pricing and packages are not flexible. I would love to use the SFMC integration and proofing tool without the huge increase in cost.

What problems is Litmus solving and how is that benefiting you?

Makes hitting send a little less nerve-wracking.

"A game changer for Email Testing"
What do you like best about Litmus?

Litmus has a great combination of all the devices and the multiple versions of devices that are most commonly used. We were able to fix all the rendering issues rather quickly.

What do you dislike about Litmus?

Ability to import an email package (a .zip) directly into the builder and/or testing/rendering/Q&A.

What problems is Litmus solving and how is that benefiting you?

The expanding functionality. We have made great use of the features Litmus has added such as the deliverability/spam testing and content review.

"Best Email Preview Tool Ever"
What do you like best about Litmus?

Email Previews of different clients Prebuilt templates for reference QA for emails became easier as we can share the links.

What do you dislike about Litmus?

A bit pricy and every time it counts the previews and sometimes it takes time to load the previews.

What problems is Litmus solving and how is that benefiting you?

We use it for email previews mostly. We look at the mobile version and the Outlook version. Outlook is very tricky and litmus helped us in creating better emails for outlook too. We refer to the built-in email templates and the code is very much organized. Sending and receiving the test emails is flawless.

"Hits almost all the important pieces of email preflight"
What do you like best about Litmus?

Email versioning, a clean Comments interface on desktop, code-level review, browser/OS emulation combo - all contribute to the troubleshooting of an email prior to launch. We've used the tracking pixel to a limited extent, and see that it works fine for the data it is intended to capture - we simply have other ways of getting the same data from different partners. Spam warnings for Subject Line and Preheader text and over-used keywords are much appreciated.

What do you dislike about Litmus?

Mobile version unfriendly; a bit slow on adding newer browser/OS combinations; experienced a few months of notification deep links (sent by Litmus to approvers); inability to efficiently render multivariate versions of the same email without sending wholly separate proof. For instance if the difference between version 1 and version 2 is a simple banner inclusion/exclusion - think "store opening" announcements for retailers like us - we have to do everything twice and approvers aren't fans of that, especially when some approvers give the greenlight or comment on version 1 and the others do the same on version 2.

What problems is Litmus solving and how is that benefiting you?

A relatively simple UI that enables the Marketing Ops team to maintain rigor in email approval governance, Litmus also enables more technical QA at the native code level. Sometimes the versioning of the code level view - or limits thereof - can cause confusion with our QA team but that is a fairly 'edge case' scenario. We've benefited by reducing errors that make it to the customer, full stop, and that's the point.

"Litmus is great for proofing and seeing how emails will look in various email clients and platforms"
What do you like best about Litmus?

I like that I have access to all email clients to see and troubleshoot display issues in one place, rather than having to snd test emails to as many email clients as I have access to. It is something that makes my job so tremendously less stressful.

What do you dislike about Litmus?

One issue I have is that, on occasion, the display for a given email client within Litmus does not exactly represent what it looks like from inside the actual inbox itself. It isn't too frequent, but frequent enough that double-checking any issues needs to be done within the email client.

What problems is Litmus solving and how is that benefiting you?

Display issues for our customers. I do not have access to all email clients, only a few. So when I need to see if our marketing emails are looking good for our customers from (arbitrarily) Office 365 on iOS, I can do that, and I love it.

"Litmus is a great solution for proofing, inbox examples, coding and more."
What do you like best about Litmus?

Litmus has best-in-class inbox previews for all major providers. With their coding tools, you can create an email while checking your output in real-time. This assures that you are creating something that will be compatible with the clients you support.

What do you dislike about Litmus?

The uptime on inbox previews is not 100% and sometimes there are problems and delays with rendering. Uptime is high, but not perfect, and it can be frustrating when you have a time sensitive project and one or more of your previews refuse to render. Fortunately this is not a common occurance.

What problems is Litmus solving and how is that benefiting you?

Sending emails is nerve-wracking; you have one chance to hit a user's inbox, and you can't take back errors. Therefore having tools to ensure compatibility and style pre-deployment are invaluable. Litmus is an essential part of our workflow, especially with more complex emails, or emails utilizing a new template or code base.

"Litmus is essential for any Email Marketing Team"
What do you like best about Litmus?

Being able to test in any browser is essential. Being able to make small changes and see how those affect our layouts is what sets Litmus apart from the rest. Their 'Builder' tool is worth everything to us.

What do you dislike about Litmus?

Can get pricey depending on your company's scale. There are a few features that cause visual bloat that would be better hidden by user preferences. If I only use one specific tool, let me only see that. Otherwise, it can be somewhat overwhelming.

What problems is Litmus solving and how is that benefiting you?

We are trying to fix layout bugs and ensure new templates that we create work for all client browsers. It makes us more confident in our platform with proven testing integrity.

"Litmus is very helpful for my job"
What do you like best about Litmus?

I love being able to validate my emails are going to look good on all devices and with all email providers quickly and efficiently. With all the variety out there, being able to do this in a one-stop shop compared to the old days, is just fantastic.

What do you dislike about Litmus?

The only thing I dislike is that my credentials get logged out every time I clear my cache! There is nothing Litmus can do about that as that would happen with any set of credentials.

What problems is Litmus solving and how is that benefiting you?

I'm solving email marketing issues - Look of emails on devices and with ESPs. Dark mode. This tool has helped our team save time without having to do rigorous manual testing, which allows us to support the business more quickly.

Litmus email previews are the best and most reliable on the market. Ability to toggle which clients to preview helps us ensure quality emails for every client.

We have been able to mobile optimize all of our email campaigns as well as make things accessibility and dark-mode readable. This is HUGE!

"Useful and reliable tools to build and check emails"
What do you like best about Litmus?

The builder part of the app, and how easy it is to send and check emails. When I've gotten stuck with something, it was pretty easy to get technical assistence.

What do you dislike about Litmus?

There are a lot of extra features that don't fit our workflow. I'm sure some people use them, but I assume part of what we pay for goes to support that.

What problems is Litmus solving and how is that benefiting you?

I haven't seen a better way to code html emails, and see how things are working compared to Builder. So that helps get something working quicker, and end up more reliable. The testing and spam testing appear to be valid checks on how in general delivery is going to go. And it doesn't take too long to run a check.

What do you like best about Litmus?

Email views and validation, deliverability features and suggestions, insights for best practices, ease of use. We are an agency and use it to test and optimize emails for our clients, and Litmus is the best for this.

What do you dislike about Litmus?

It's a little expensive, but worth the cost to make sure we offer the best email services to our clients. The user interface changes from time to time, and we have to somewhat re-learn how to use it.

What problems is Litmus solving and how is that benefiting you?

"I Love Litmus!"
What do you like best about Litmus?

Litmus has saved my butt more than one time! I love all the features and the many different ways that you can check for errors. I think it is a REALLY great product and we have only scratched the surface for using its features.

What do you dislike about Litmus?

I really want to use Litmus for Proofing, but I cannot until the platform accepts .pdfs as documents. We have to be able to click through on multiple variations of the email, and I don't want to code each variation. It is complicated, but that is what we need.

What problems is Litmus solving and how is that benefiting you?

We solve all kinds of problems with Litmus, especially Dark Mode. It has really helped us visualize what our images and text looks like. Being able to change the code and have instant reviews keeps us moving and correcting quickly. Plus, I love that it shows accessibility issues too. This helps us get better at coding for everyone.
