When you are a developer, you often have to do cross browser testing, or email testing cause sooner or later you are probably going to need to test it on multiple email clients from outlook to Gmail to even in some rare cases…lotus notes.

Using a program like Litmus or some other email testing program can help save you time and effort cause you will be able to see how each custom email newsletter will display on the many different email clients out there. So you can get a grasp which email client it breaks on.

Also another feature of litmus that can save you time is the spam catcher, it will generate a report that will give you a ballpark idea of if your email template will be caught in a spam catcher and if you will definitely get listed, so this can definitely help you carve the ultimate email newsletter. Now that being said, there is also a feature that will will allow you to test webpages on various browsers, and what is good about this, is that it uses base line browsers that are uncached. Which means they are seeing the page fresh for the first time every time on every retest.

That being said, this is probably one of the most expensive tools out there due to its cost. Costing around 79 dollars monthly for just unlimited email testing, this can definitely kick you in the wallet hard if you don’t use it all the time. And when you need to do spam testing, this will definitely double punch your wallet cause…its 149 per month. Yup thats right you got to double the price to use the cool spam filter.

In closing, I think Litmus is definitely one of those great tools that if you are a coder that does a LOT of email marketing and newsletter this can be a tool that saves you time and money cause you can test on everything at once and find out what qualifies as spam in each newsletter. Also be sure to subscribe to their email newsletter cause Litmus will talk about the tricks and ways to craft great responsive emails as well as developing cool emails that stand out of the bunch of boring emailers that you come across.
