Never fear a broken email again

It’s every email designer’s and developer’s worst nightmare: The links that don’t work, images that won’t load, formatting that fails to render… and the list goes on. All it takes is one small error to have a big impact on conversions. That’s why Litmus was created with design teams in mind. Our powerful email marketing solution gives you full visibility into every last layout and link—and frees you to focus on new ideas as you build, code, and test campaigns.
