Preview your email in 70+ combinations of the most popular email clients and devices.
Unlike web browsers, email clients are far more strict when it comes to HTML and CSS standards. Just because your email renders properly in a web browser does not mean it will render correctly in every inbox!
Are you sure your emails aren't getting marked as spam?
Imagine, you think you are running great campaigns, only to find out you are getting marked as spam by numerous spam filters. What would it mean for your business if you were able to diagnose and solve deliverability issues you didn't know you had, before you hit send?

Pros
What I love about Email on Acid is how quickly I can see how my email renders across all email providers as well as internet browsers. I always rely on this tool to make sure my emails will be sent out with no issues. The one cool thing that I really do love is that I can use their optimizer to check my HTML code. Since I am not fully fluent in coding, I find myself using existing templates and making modifications to the code. Many times I notice an error in the code and am not sure what is broken or wrong, but when I take the code and run it through Email on Acid's code optimizer, it tells me the errors and fixes them.
Cons
I have no complaints about Email on Acid. I have always had a great experience with it.
Pros
I've been using Email on Acid for about 6 years, and its managed to evolve, adapt, and stay relevant as HTML email gets more complicated in a more responsive world.
There is almost no wait-time between when I deploy a test email to Email on Acid and when I can start viewing renderings.
They also have great articles about HTML email trends, useful snippets for those hard to fix bugs (I'm looking at you Outlook).
Cons
Their latest (within the last month or two of this article) UI refresh is a little wonky. I'm sure they'll have the kinks out by the time you read this.
If you're a company with an unlimited budget, then I would choose Litmus. But for the rest of us, especially freelancers/contractors, Email on Acid is a great choice that won't let you down. I have peace of mind when everything finally renders appropriately across email clients/devices. Getting there can be a royal pain, but EoA is a major help.
Pros
Email screenshots happen almost instantly. You can automatically trigger an email test by sending a test message to your EoA account. You can configure which email clients to include, and share the results.
Cons
This still feels a bit like a 'budget' product, compared to Litmus. The price tag definitely reflects that, and boy am I thankful there IS a cheaper option. So I won't complain too much. But I do sometimes get frustrated that certain screenshots take forever, and sometimes they render badly. Small price to pay for a product that's actually in my budget as a freelancer.
Pros
It was easy to get started. I LOVE being able to just send an email to a "secret" address and get visual results for various email clients for testing. The pricing is fair and straightforward.
Cons
Can't seem to figure out how to get help with correcting small code issues or code typos. Would be a nice feature. Perhaps the platform could offer tips based on your html.
I use this software A LOT. It is very intuitive to use and it is helpful in ensuring your emails look great.
Pros
I love the idea behind this software so you can see how your emails will appear in multiple clients, but...
Cons
I dislike that this software allows you to see your ememo across multiple clients because then project managers get caught up in details in obscure email clients.
