"Litmus is central to our email design and distribution process"
What do you like best about Litmus?

As a designer, previews & QA are a big part of my job. Litmus makes the review process easy to see identify flaws and easily show our developers changes.

What do you dislike about Litmus?

Our library has gotten huge. Between contractors and in-house developers, the organization on our end affects loading time.

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

Being able to start from scratch when creating a fully customizable design for our email marketing content allows us to elevate our brand and stand out from our competition.

"Litmus Review 2023"
What do you like best about Litmus?

The blog and community information is extremely helpful. I like being able to gain insights from across industries and applying them to increase deliverability, inboxing, read-time, and next stepst to leverage when testing. Being able to see designs and concepts across browsers and devices is also increasingly important.

What do you dislike about Litmus?

The limited number of previews across devices, which I know is based on our business account level, but for our business, we are unable to increase our plan.

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

Read Time, and inbox placement.

"Comprehensive tool for marketing strategist"
What do you like best about Litmus?

This tool is very powerful and allows you to take the right decision and optimize at the best your email campaigns. It's very precious to be able to analyse in details how your email campaign could be optimised and Litmus allows that. Integrated with marketingcloud it's even more powerful.

What do you dislike about Litmus?

The start need more detailed guide in order for a beginner to start Litmus use. but it's not so complicated and after the tool is easy to use and implement so that's ok.

I optimize the email content, subject line optimisation, content rendering and to make sure My email campaign will render the better as possible to optimize our communications to customers and prospecs.

"Very easy to use and valuable tool."
What do you like best about Litmus?

Rendering tests and builder capabilities

What do you dislike about Litmus?

how rendering counts are done and cost. Would like to be able to easily create listed of testing clients when troubleshooting issues instead of having to constantly check and uncheck boxes. Makes us less efficient to do that, but if we don't then we can quickly blow through our allotted renderings for the month if we don't.

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

Rendering issues especially with Outlook.

"Director of Email Marketing"
What do you like best about Litmus?

Litmus checklist within Salesforce Marketing Cloud Ability to tag/collaborate on email proofs within Litmus Email upload speed Unsure how it compares to competitors!

What do you dislike about Litmus?

It was a little glitchy at first, but we were able to resolve that with help from customer service. I'm not sure how the tool could be much better! Perhaps it could be easier to find read time based on emails.

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

Checking email links, upload time/size, collaborating and reviewing emails among various teams at my company; We are more productive because of it! We have also been able to review emails within the SFMC platform which cuts down on production time.

"Great collaboration product"
What do you like best about Litmus?

The fact that I could work real-time with people from other timezones to edit copy for my emailers to the organization and clients. I haven't worked with competition but this was a great product

What do you dislike about Litmus?

Sometimes it takes a bit of time to load - but in my case mainly due to me being new to Litmus. I also found that sometimes I needed to log in frequently as I kept getting logged out for some reason.

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

I was trying to send emails with global language taking into account company and country nuances and culture. Litmus very clearly helped me in ensuring that copy was accurate and well articulated

"Litmus makes necessary easy!"
What do you like best about Litmus?

The previews and code builder are by far my favorite features. I would use the "push to ESP" feature more if we hadn't just swapped most of our clients over from Mailchimp to Klaviyo.

What do you dislike about Litmus?

The UI can be a little confusing at times when you are in a hurry. It's tough to quickly jump to a section when you need to.

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

Really solving accessibility and keeping the design intact.

"Perfect for QA before clicking send!"

The checklist/QA feature is ideal when building out HTML emails to catch any last-minute changes and accessibility requirements.

The reporting could be more robust and provide more details into performance.

We are able to make our emails more accessible to those using screen readers and ensure our HTML is properly tagged. It made us realize our templates needed a closer look.

"Litmus Review"
What do you like best about Litmus?

The best thing I like about it is that It gives you all the email previews you could ask for. It has an editor built out just for developing emails. It is very cost effective.

What do you dislike about Litmus?

The interface could be better. And the pricing is a little too expensive for a small company or a start up.

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

We don't have a developer in our team. So it's very handy when we can easily code stuff without any breaks in our emails or links.

"If you send a lot of e-mails, this software is for you! "
What do you like best about Litmus?

When I send out e-mails with links, I would have to go back and click on them to make sure it works. But with Litmus, it does it own it's own. It will confirm the link, instead of you clicking on it. You can also review your picture that's attached, and they will notify you if you are missing any pictures. The software is also good for Marketers.

What do you dislike about Litmus?

There are no Cons so far, still experiencing the software.

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

Problems we can solve are making sure that the marketing communications is presented across the market and multiple email clients.

"Litmus Email Creating Software review"
What do you like best about Litmus?

Litmus Email has user friendly options to designing a professional looking email. It creates an email that can include your images, links, proper tracking id's, etc. Using Litmus for online marketing helps the user get their emails (their ad campaign) to the inbox instead of the spam box.

What do you dislike about Litmus?

I wish Litmus was able to detect why we're experiencing certain issues between email clients. It's probably wishful thinking at this point given all of the variables Litmus would need to consider in order to make a sound suggestion.

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

I was trying out Litmus for a election campaign - marketing campaign. It was helpful in creating email content - which was quick and easy. It's honestly a reputable software but there are tons of similar programs out there that can equally do that job.

"Litmus Review"
What do you like best about Litmus?

Shows a huge number of email inbox providers, including the versions. Also love that it provides specific things to update when testing. UI is pretty user-friendly as well.

What do you dislike about Litmus?

I haven't set up the MKTO integration yet, so that's on me. Everything else works fine!

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

email deliverability/quality. Realized that our email template/HTML is not optimized and that we need to add blank space after the preheader copy.

"Admirable emulator for email clients"
What do you like best about Litmus?

This tool saves me a great deal of time. Rather than maintaining a multitude of test email addresses and devices, and signing in and out of them, I am able to sign into one easy to use tool to quickly review them for rendering issues. I am then easily able to share the results with other stakeholders.

What do you dislike about Litmus?

I have found the renderings to be short of 100% reliable. I have come across many situations where Litmus showed rendering issues, where the actual email client in question on the relevant OS/version did not.

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

Email render testing. Tools such as Litmus and Email on Acid greatly increase the speed you can accomplish these tasks in.
