Like

It's very easy to send emails to their folder to get approval. easy to see how the email will look in a different mailbox.

Dislike

I don't have any complaints about the platform - I have gotten comments from other team members that they sometimes don't get notifications when I send over an email proof but it doesn't happen often and doesn't impact my opinion of the product

Dislike

NA

Dislike

The interface is clunky and sometimes refreshes on its own while you are working. The first page is overwhelming with lots of emails coming right into your face when you log in.

    Litmus is great for testing emails using different attributes such as dark mode, different browsers and what not. It provides a fair understanding of how our emails will look for different people with different hardware and software.
