"Litmus is a MUST for email marketing"
What do you like best about Litmus?

The two most helpful features on Litmus are Previews and QA and Analytics. They both provide valuable insight into our email marketing initiatives for the quality of our email designs and user engagements across all digital devices. Not related to the platform, but Litmus's email newsletters are extremely valuable. I open every email from Litmus! These guys are doing it right!

What do you dislike about Litmus?

Litmus can do much better with its Accessibility feature. For example, the screenreader is pointless. I don't use it as it needs a major upgrade. The first Alt text for image path always says missing although it never is. Might be a bug that Litmus needs to address.

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

Litmus is so crucial for our email marketing programs. Not only does it help us preview our email templates across all devices but the analytics feature allows us to track metrics our email marketing and marketing automation platforms don't support. For example, Read, Skim read, and Glanced rates. Reading environments, top email clients, and Dark Mode usage.

"Love Litmus!"

I love the fact that I can preview my emails on Litmus - it has been incredibly helpful. I also like the code preview option where I can see the backend of my code.

What do you dislike about Litmus?

There isn't anything that I dislike about the platform. I think the wide offering of the product is great and don't see any areas of improvement at this time that would help me.

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

It's helping us streamline our email testing processes and ensure deliverability. I am more productive because of using it and our business performance has increased.

"Lifesaver for efficiency!"
What do you like best about Litmus?

The Proof tool - has cut down on so much back and forth with clients and keeps any revisions in one centralized location.

What do you dislike about Litmus?

Approvals on proofs are only sent to the account that created the Proof. I want to be able to assign who gets those notifications.

Litmus has helped improve efficiency, quality assurance and communication with clients.

"Litmus is for Everyone"
What do you like best about Litmus?

I like the option of being able to use an easy interface for coding or html. The option to see multiple platforms and how the email will display to the end user. Creating and saving blocks of code that are used on the regular Integration of Litmus with our Salesforce Marketing Cloud platform

What do you dislike about Litmus?

Nothing I can think of at this time. Overall, we're happy with LItmus and plan to use the product for the foreseeable future. I do wish that the design portion of the platform was free. Not a deal-breaker but surprised to see that such a 'simple' feature requires an additional upcharge.

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

How the email is rendered in multiple platforms and what we need to update, and not update, for those who are using a specific platform most. And not putting as much emphasis on those platforms that our audience isn't using.

"A game changer for our processes."
What do you like best about Litmus?

The ability to view dozens of different email clients in one UI has been a major unlock for us. Before Litmus our team was managing canary accounts on several email clients but it wasn't scalable.

What do you dislike about Litmus?

The only missing feature is a mobile app for iOS. We often test deep links on our app and there isn't a great way to check these using Litmus. Hopefully this will be added soon.

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

We are now able to troubleshoot rendering in dozens of email clients in a seamless UI. We didn't have a scalable process before using Litmus. This has been a big unlock for us.

"Keeps emails short and sweet"
What do you like best about Litmus?

Inspecting email contents in a development setting rather than sending it to actual recipients. It has a simple implementation and a simple GUI

What do you dislike about Litmus?

Some customers may not receive emails so I have to perform a blacklist check to ensure our email has not been blacklisted to reduce spam

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

Creating a sense of urgency in my subject lines strategically to get people to take action. Viewing my email and see whether it will be considered as spam

"Responsive, easy-to-use, collaborative QAs"
What do you like best about Litmus?

Builder: Litmus builder is an easy solution to build templates collaboratively, figure out issues in code, and implement responsive templates. You can add modules, set up brand design and colours, and even analyse your campaign performance. QA process is seamless and collaborative. You can set your template proofs, link proofs, basically, your entire QA chart and easily complete the process ensuring 0 errors.

What do you dislike about Litmus?

The only suggestion I have is to build a live builder ie if I am fixing code for a specific view (mostly outlook) in the builder, I could see live changes on the view as well. Currently, I have to send a test and the view takes 5-10 seconds to load.

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

Template QA and building responsive templates. We have a strong QA process and multiple stakeholders. The public test copy option helps us easily share tests for reviews across and outside the organisation, making the QA process seamless.

"Very usefull and powerfull tool"
What do you like best about Litmus?

all services provided by litmus that allow you to have all under control and to track the performance of your campaigns. Adding the User Interface is very simple and user friendly. You can find a lot of interesting features like tracking and measurements that can help you to understand how your emails work and to understand if you have to improve messages or other things of your communication to catch the interest of your customers. adding you can try and catch error codes directly from the previews for each client/device. This is very helpful with Outlook because a lot of problems occur with this email provider and with litmus you can debug your code and fix it to obtain the perfect email. Then you can test your emails before sending them to the customer, also you can build an approval process to be sure before approving an email and to split tasks for each member of your organization.

What do you dislike about Litmus?

unfortunately, I have to say that the pricing model is a little bit expensive because the model is based on the number of reviews. Usually, when you test an email you need to preview a lot of times the same email to see how it fits on several providers, you need a lot of previews.

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

we have solved a lot of problems related to deliverability and also to the content adaptation of emails based on several devices and clients both for desktop and mobile.
