Litmus provides the security any email marketer is looking for. With Litmus, you'll see how your email renders across many different platforms, providing ease of mind with your email designs. Review collected by and hosted on G2.com.

The only downside to Litmus is it can be overwhelming to review all the provided platforms. It's a pretty great problem to have! But I wish there was a smaller list of suggested providers that is easier to manage but still comprehensive! Review collected by and hosted on G2.com.
