"Test multiple device output on one device"
What do you like best about Litmus?

As an email marketer, I need to check the responsiveness of my HTML emails. Litmus allows me to do that for multiple systems in one go. I don't have to send test emails and check multiple devices anymore.

What do you dislike about Litmus?

I wish the tool suggested changes to improve the output quality of the emails. Right now, that is not possible.

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

Litmus reduces email test time. There are multiple operating systems, and it is not always possible to create emails for every OS. Litmus helps us prioritize this.

"Integral Part of our Email Processes"
What do you like best about Litmus?

It allows us to test many browsers at once, and identify issues before we send to our clients.

What do you dislike about Litmus?

As browsers always change, there always seems to be some issues we can't identify with Outlook (it's always outlook...). Sometimes there are line breaks in emails that aren't always visible on Litmus.

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

Our developers use this to check emails before they do any test sends. It lets us see some dark mode renderings, and how things show up in gmail accounts. It's a great way for us to make sure we are putting our best foot forward and reducing errors before clients review.

"Best-in-class email testing"
What do you like best about Litmus?

The best-in-class for email testing. Its pre-test sending is invaluable for making sure emails look right on every mail client. Pricing is reasonable. Its content and resources are really helpful too.

What do you dislike about Litmus?

I doesn't take all the pain away from sending a bulk campaign. A Grammarly style spelling and content checker would be really useful.

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

Making sure our emails look faultless on every mail client.

Do not have any majord dislikes since the platform continually adds new features and functions.

"The Right Tool for Building, Testing and Optimizing Email Campaigns"
What do you like best about Litmus?

Litmus is best-in-class for email testing across email providers, and they have demonstrated industry knowledge in the field of email marketing. They offer tons of resources through blog posts, white papers, and the like. I really enjoy using Litmus Builder for drafting & testing our email campaigns. The Litmus team is responsive to feedback and has actually implemented some of my ideas for improving UI/UX.

What do you dislike about Litmus?

I think Litmus is making some good improvements in terms of the Builder interface, but it’s still a little bit clunky for me. Since we draft all of our emails in Litmus, I’d like to have better organizational tools for managing all of our content.

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

Being able to build *and* test our email campaigns within Litmus makes for a simplified production workflow. Most ESPs offer email production & testing tools that are mediocre at best, and Litmus makes it easy to push completed messages to a number of ESPs.

"Such a great tool to render emails in different clients."
What do you like best about Litmus?

ESP rendering, proofing, and sharing email previews.

What do you dislike about Litmus?

Sync sometimes will lag when sending a direct test to the Litmus proof.

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

Making sure our emails render correctly across multiple platforms, and easy to receive feedback or notes to make updates with.

"Litmus is Essential for Email Teams"
What do you like best about Litmus?

I use the builder feature almost every day, but I love Proof! It's excellent for team and client communication.

What do you dislike about Litmus?

There are some weird inconsistencies with naming documents, but overall, I am incredibly impressed by the product.

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

We are using Litmus to create emails across a global team and to attain client review. The platform is really versatile and offers a wide range of features to help us grow. We use a wide Litmus to create a wide variety of campaigns, localized in many different languages geared toward hundreds of different segments and using a great tool like Litmus helps keep the entire team organized. Our team first got know Litmus at the Litmus Live conference in San Francisco a couple of year ago. Working with a trusted industry leader ensures that we are on the front lines of the latest trends. We've also worked with Litmus on user testing, which was an immensely helpful experience for our team. I love working with a group that values user feedback in order to improve their product. We are in our second year of our contract and I hope our use continues! If you are a team of one or a team of many, Litmus provides a wide range of tools to help everyone succeed. We have yet to implement analytics -- I think that would be a great next step in taking full advantage of the Litmus experience. Thanks to the team for all they do!

"Staying organized with Litmus "
What do you like best about Litmus?

We came on board right as Litmus changed site design into a sleeker, more efficient email processing client. The new layout and organization of options is far more helpful to our workflow and has upped our productivity two-fold. I love that you are able to customize Tasks on the Summary page and insert points that are relevant to how your company creates and delivers emails. The customization of the Summary page really helps when more eyes are looking at your email. The whole team really appreciates the Previews option where we can pick and choose who are targeted email client should be (with the assistance of Analytics). Each render helps maximize our emails for optimum performance. Speaking of Analytics: the information from Analytics is super easy to digest, easy to share and helps with deciding where to spend our time on our email design choices.

What do you dislike about Litmus?

It would make our emails that much more relevant if we could repair/rework our emails according to Litmus' Accessibility suggestions within Marketing Cloud on the fly instead of deep diving into code to fix.

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

We have 5-6 departments reviewing one email and using Litmus ha allowed us to streamlined our review process using the Checklist and Proof dashboard.

"Great experience. Improvements probably needed, but they're always coming"
What do you like best about Litmus?

I really enjoy the builder and analytics process.

What do you dislike about Litmus?

I don't like the organization on different tools. For example I wish Builder had some way to store email templates in different folders based on campaign. The same would be helpful with analytics. It gets hard to search for exactly what I am looking for, especially when we send out so many emails.

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

We do our email rendering testing in Litmus and capture analytics through the Litmus pixel to solve for technical/design issues and to provide comprehensive reports to our stakeholders.

"Best user experience and professional email collaborating tool"
What do you like best about Litmus?

The user interface is great. The workflow type edit recently made is really useful. Litmus Proof is what stands out about using Litmus though. It is easy to update code, get feedback, and preview and send out tests.

What do you dislike about Litmus?

The cost is the biggest turn-off. Also I wish that when you update a proof by email link it would update the builder code. Everything else is great.

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

email collaboration across teams are the biggest win from using Litmus. In some cases what was literally weeks and weeks of back and forth edits has been accomplished over a couple of days, without seemingly adding to people's workloads.

What do you dislike about Litmus?

Hope Litmus would build a feature for drag and drag Email Builder and at the same time generates an html code.

"Litmusis awesome and cool"
What do you like best about Litmus?

The editing platform for email coding and previewing, with the continual feedback window pane open on one side, helped me very much when designing the email and debugging it. I also like how easy it is to input and test emails across multiple browsers, with just a click of the button. There's good e-marketing training as well.

What do you dislike about Litmus?

Sometimes I lose my place using the dashboard and forget how or where to get a tool. That is a minor thing.

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

We needed to test emails across all browsers for our email programs. We can run a quick Litmus test on emails and then know how it will look. It saves so much time and labor. It also is good for proof-reading and debugging emails that I prepared.

"Solved All our Problems"
What do you like best about Litmus?

That we can test, approve, and get engagement data. This has streamlined our QA process. We are able to look at how our emails render in the mailboxes we need to check. We can see which providers our users have and optimize for them. The fact that the team takes feedback and actually works on it.

What do you dislike about Litmus?

When approving an email you get a different notification for every comment. You can't tell if it's a conversation on one or multiple. That proof users can't use Slack or see the organizational structure. That when we have a proof and rename it the notifications and everything just have subject line.

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

Our QA process is so much more streamlined. I would manually check different renderings and wouldn't be able to do it every time because of the time spent. We now have much better visibility into the process. Everyone in the company can view and it's easier to explain. Communication for approval has a location that people can now follow.

"Must-have for email marketing"
What do you like best about Litmus?

It makes it extremely easy to test all of my emails, edit the code, and make sure things are good to go before I head out the door.

What do you dislike about Litmus?

It doesn't autosave when you leave the page - which is a blessing and a curse sometimes! :)

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

I use Litmus because I can edit my emails and see how coding impacts my emails in real time. I can also preview how my emails will look across a variety of platforms (phones, desktop, outlook, gmail, v 2017, v 209, etc.)

"Must have for Email Marketers"
What do you like best about Litmus?

The best parts are the email previews, so you can see what your email looks like in every inbox. This helps you catch errant code and make sure every user has an optimal experience. You can also put emails in the builder tool to easily tweak and recheck code. They also have super helpful blogs/newsletters.

What do you dislike about Litmus?

It's not a cheap tool, so the barrier to entry is high. So you need to be running a big/robust program to make it worth it. It can also be overwhelming to jump into and understand the full extent of its capabilities.

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

It's a QA tool to ensure our clients get the best content possible and their customers get the best experience. Even for those who feel highly versed in email best practices, it's a good gut check to make sure nothing gets missed in the production and sending process.

"Easily check how your campaign will look like"
What do you like best about Litmus?

In place of sending the email to different emails and check them on different devices and browsers, you just need to check it with Litmus.

They need to have more integrations with other platforms to allow easily check the emails despite the service you want to use to send them.

"Effective email tool"
What do you like best about Litmus?

It is helpful to see the different variations of emails in different email providers. I like being able to go in and edit the code and see how it changes the email/select the different sections.

What do you dislike about Litmus?

Sometimes more recent updates to email providers aren't shown immediately. I also wish there were more ways to diagnose what is wrong with an email within the tool.

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

We can easily see what our emails look like in various email platforms.
