"Great at helping ensure your email marketing is perfect across devices"
What do you like best about Litmus?

The ability to quickly test emails in a variety of email apps and services as well as being able to build and edit emails on-site.

What do you dislike about Litmus?

Sometimes it takes a few moments for Litmus to "recognize" a new email I send to it, or it quickly does but is not apparent when previews will be available.

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

Most often we're checking and resolving issues with emails not displaying correctly, and responsively in apps such as Microsoft Outlook, iOS Mail, etc.

"The best email render testing tool"
What do you like best about Litmus?

I like the flexibility of Litmus. I can build an email in real-time within Litmus or send proofs to my personal folder from the ESP. Our team depends on Litmus every single day.

What do you dislike about Litmus?

As with any email rendering tool, I notice inconsistencies from time to time. Something may look wrong for iOS Outlook, but then it looks normal when testing live. However, this is fairly rare and I think just a factor of the ever-evolving world of email development.

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

We test all of our templates and builds within Litmus (in addition to live testing on our own devices to verify the accuracy of the renders). This saves us soooo much time that we can then utilize on other opportunities for our clients.

Litmus has made it easy for our team to view our email across multiple clients all at once. I also enjoy reading the Litmus blog posts for valuable insights.

I know there are many more features to litmus that I have not used yet. It would be great to have more tutorials or explanation into these unused features.

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

We have been able to optimize our emails across multiple email clients with litmus, which saves us from looking badly to these customers with potential errors.

What do you dislike about Litmus?

Nothing stands out for me that I dislike

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

"Ease of use tool for verifying your email layout across multiple mail clients."
What do you like best about Litmus?

Quick ability to check mail layout across all most commonly used mail clients. Also the ability to save the mail for future reference.

What do you dislike about Litmus?

Grouping the saved emails is a bit convoluted after the latest UI updates. Maybe I got used to the old way of grouping the emails.

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

We have multiple emails we sent for receipts, some are old HTML that were broken on mobile breakpoints. We sanity check the emails regularly from a QA team point of view. Not just marketing emails

"Litmus is the best solution for any company doing email marketing."
What do you like best about Litmus?

Litmus is really a great software for email marketing. Since the first day we installed it, it has brought a huge impact in our company. It is expensive but necessary for any company doing email marketing. It is super incredible and supports nice and highly customizable features that does not require any training to learn and use. Add-on features are very neat especially for people who like them. It is great for all companies, both small, medium-sized and large.

What do you dislike about Litmus?

Litmus is expensive but worth the price since it is a powerful and easy-to-use application for email marketing. I have ever worked with different similar platforms before but Litmus is the best when it comes to effectiveness and performance.

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

I love Litmus customer support team, they respond quickly and the application keeps updating thus making it more effective and productive. It is really a flexible email updating and testing tool and i highly recommend it.

"Litmus...an outstanding and exceptional product for email marketing."
What do you like best about Litmus?

What i like most about Litmus, is how it simplifies and speeds up testing my content. I like the fact that i can access it from anywhere anytime and from any of my devices. It also enables me to create professional campaigns and instantly send them. I like the ability to manage email lists, send outbound emails within seconds and personalize emails. It has a very responsive and friendly interface which makes it easy to learn and use so no extra training required.

What do you dislike about Litmus?

I think it would be more advantageous to have more options for integrating mail platform into the spam test. Apart from this i have nothing else to mention as a dislike about Litmus.

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

Litmus is a solid and robust application suitable for any company doing email marketing. It is a straightforward and lightweight application that enables us to effectively and efficiently engage with customers and business partners around the world. It has made our work more easier and efficient by allowing us to market our services and products across the world thus saving us much time and money.

"Easy way to share and approve emails"
What do you like best about Litmus?

I really like that I can click on any part of the email, or highlight a passage of copy and leave a comment. This makes the amends process really easy as without it I am having to waste time describing what is to be changed over email. I like that I can share the email proof and tag different approvers with ease which then sends an email reminder too. I also like that the email creator can sort emails into folders so that I can see which emails are part of which campaigns easily. Finally, I love that I can preview what the email will look like on a phone as well as a desktop - this is great for checking if an email is too long, or if the graphics or titles are rendering correctly in the mobile version.

What do you dislike about Litmus?

I would love to be able to have a search function for the emails that I have been sent to approve so that I can go back and see them at a later date, incase any updates need to be made.

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

* mobile view - emails that we were sending previously were too long in this view and we now yield better click rates by addressing this * saving time on the approvals process * having a documented approval system so that I can prove that someone has signed an email off to be sent

"Invaluable tool for email marketers"
What do you like best about Litmus?

Everything that I need to build, proof, and create emails and email campaigns in one platform

What do you dislike about Litmus?

i don't really dislike anything about the platform. Maybe being able to run Salesforce ampscript personalization within the litmus builder itself? not that big of a deal though since there is litmus integration in salesforce.

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

Saving a bunch of time with their design library, and proofing tools. Also being able to create a design system within litmus.

"My go-to email testing tool!"
What do you like best about Litmus?

I have used Litmus as my email preview/display tool in both Pardot and now HubSpot for years. It's indispensable when you want to see how your email campaigns will display on different platforms.

What do you dislike about Litmus?

I have found it to sometimes be slow-loading when generating previews, but not too terrible.

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

One of the main problems I have solved with Litmus is the Outlook previews. As you may know, Outlook can be tricky when designing emails, but with Litmus it takes the frustration out of not knowing how emails will display on specific email providers.

"Email's Best Friend"
What do you like best about Litmus?

My favorite thing about Litmus is how it simplifies and speeds up testing my content. It doesn't matter what email tool I'm using. I can leverage Litmus to render and preview my emails before sending them.

What do you dislike about Litmus?

I would like to have the ability to seamlessly update my content in Litmus when making changes after previewing it there. I have to switch to the email tool where the email lives or copy and paste if I edit the content in Litmus. This would be a great enhancement.

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

It saves me time and simplifies testing. Instead of managing multiple test email accounts and related test email lists I would send tests to, I can focus on identifying issues uncovered by Litmus and applying the corresponding fix in my content. This saves hours and centralizes my testing process.

"Best rendering tool"
What do you like best about Litmus?

Litmus has always been my number one choice. It has improved considerably over the past, so we, as Devs/QAs, trust it. The customer support team is also pretty efficient & responds quickly to any technical issues.

What do you dislike about Litmus?

There's always room for improvement since we work in an ever-evolving world, but there's nothing specific.

"A full 360 service for building and ensuring deliverability of your communications"
What do you like best about Litmus?

We love Litmus for the ability to see the specific reasons why an email may fail to deliver, from time taken to load an image and accessibility to real world processing into inboxes, tracking each of the main play spam filters. The email building tools are top-notch and really do take the pain out of the building and visualising how your code will render in every email client.

What do you dislike about Litmus?

While not Litmus' fault and because I have to dislike something, it would be advantageous to have more options for integrating mail platforms into the spam tests. Currently, we have to save a CSV of email addresses from Litmus, import them into our system, and send the campaign. Email addresses changing for each spam test, this can become a barrier.

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

Email deliverability scores and improving reputation with first class email builds.

"Collaboration and Testing"
What do you like best about Litmus?

Litmus allows multiple people in my organization to review emails and collect feedback all in one place.

What do you dislike about Litmus?

The one thing I dislike is the need to resubmit the email using a new email, causing the creation of data extensions in my platform. I use HTML paste instead, which seems to work well now that we can update the subject.

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

Litmus allows for collaboration on edits to emails. We are able to ensure our links are working properly and it offers us a tool to share with our content creators what is best practice to avoid spam.

What do you like best about Litmus?

Inbox previews have been incredibly helpful in the development of our new email templates, and sharing them with our designers.
