"A must-have tool for email marketing teams"
What do you like best about Litmus?

Coding requires trial and error... lots of it. I'm able to identify emails with rendering issues before deployment. I also like how stakeholders are able to view proofs and easily write edit requests or approve emails.

What do you dislike about Litmus?

When incorporating GIFs or videos, screenshots are often taken while the file loads. Also, I'm not a fan of the 30 days expiration on proofs. Lastly, there's no way to delete proof versions.

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

I take pride in ensuring emails I code look good so by being able to preview them, I'm confident nothing embarrassing will show up in inboxes. Being able to collaborate with stakeholders at the Proof level makes the entire process easier for me.

"check if platforms works as you think they do"
What do you like best about Litmus?

I dont want to say names but OUTLOOK never works as I think it should do, so Litmus has been really helpful to test me wrong and make the changes needed to outlook stop being a jerk with my work.

What do you dislike about Litmus?

I dont think it is litmus problem but sometimes it doesnt work as medallia does, so sometimes even if it looks kinda weird on litmus i'm sure it is working as expected, but i dont think it has something to do here.

Not really sure about this one, but I think it has more platforms than when I initially started using it so this is very useful because now I can test my work everywhere
