eCommerce Email Marketing Manager

When using templates over and over and changing the code, errors can happen and I fully trust Email on Acid to tell me if my email if my email is broken or not rendering properly.

I dislike that this software allows you to see your ememo across multiple clients because then project managers get caught up in details in obscure email clients.

What I love about Email on Acid is how quickly I can see how my email renders across all email providers as well as internet browsers.

The Litmus community is a great place to have your coding issues answered or for you to help other coders with issues.

Promotional Materials Group

This software is easy to use at the onset; I also particularly like the spam check feature, which helps with advising clients on how to best design emails.

We have been benefitting from this software through template QA and creating templates that are responsive enough.

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 pretty quick.

Team Lead, Campaign Specialists

There should really be a quick unsub option on each checklist. Spam tests are not quick to set up.

Junior Web Developer

The best testing experience for emails, quite simple to get used to and mostly an accurate representation of emails.

Webdesigner / Webdeveloper

Very helpful and very understanding. So for customer support i would give them a 10 out of 10.

Designer

It also lacks the full features of email analytics such as spam filter testing.

Sales Engineer

Possibility to preview emails for the different OS/formats (desktop, mobile, tablets, etc.) for PC, Mac, Android, etc. Great integration within Salesforce Marketing Cloud.

Director

Highly recommend if you have the workload to justify the cost.

Lead Hand Shaker

Cost, the cost is very high and it is vary hard to justify the cost to other people in the organization.

Litmus Scope is an essential tool, but it is inconsistent and seems to be a largely ignored feature. No notification system for when campaign approvals are finished.

For a marketing agency, is can be a useful tool; just do your research before using and be aware of the contract details regarding pricing and service.
