## Email on Acid Reviews
  ### 1. Essential Email Testing with Seamless Previews

**Rating:** 4.5/5.0 stars

**Reviewed by:** Adarsh P. | Senior campaign spcialist, Mid-Market (51-1000 emp.)

**Reviewed Date:** April 28, 2026

**What do you like best about Email on Acid?**

I love the fact that with Email on Acid, I don't need to use a live device to preview emails, which is really helpful for our day-to-day activities. It allows us to send proofs to an ID created for our account, and the proofs get split into different ESPs, providing us with a screenshot of each one. The initial setup was simple, just like logging into Facebook or Instagram.

**What do you dislike about Email on Acid?**

I find it challenging to make Email on Acid more custom. Creating custom cases for each situation is a shortcoming. It would be helpful to have an option where you could name a set of tests that only include selected platforms or OS screenshots. Too much information can blur the actual requirement.

**What problems is Email on Acid solving and how is that benefiting you?**

I use Email on Acid to test emails across different OS and platforms, solving rendering issues. I love that it previews emails without needing live devices, streamlining our day-to-day workflow by providing screenshots of email proofs split into different ESPs.

  ### 2. Hard to do effective email marketing without this!

**Rating:** 5.0/5.0 stars

**Reviewed by:** Jeff L. | Enterprise (> 1000 emp.)

**Reviewed Date:** September 14, 2023

**What do you like best about Email on Acid?**

I've used Email on Acid for years, and find it to be a critical tool for our email marketing program. Viewing and actual rendered version of an email in the most common inbox providers is invaluable when troubleshooting to ensure a perfect user experience for each subscriber. What displays fine in one browser client may not in another and vice versa. EOA takes the guessing out of the equation. What's better is that EOA provides recommendations for how to fix or edit the code to display correctly in many outlying instances. This is very helpful when troubleshooting. We don't use the templates, however they do offer many free downloadable templates which make coding a fluid-responsive email super easy for non-technical marketing folks. I would highly recommend Email on Acid to any email marketing team.

**What do you dislike about Email on Acid?**

The only downside of Email on Acid is the price. Would love it if there was an option for inbox rendering without any other features that could be a cheaper alternative for marketing teams on a very tight budget.

**What problems is Email on Acid solving and how is that benefiting you?**

Inbox rendering continues to haunt email marketers. EOA helps solve nuance code requirements of the many various browsers and inbox clients. Lately we've also benefited from the dark-mode coding tips and tools.

  ### 3. Affordable but at a cost

**Rating:** 2.5/5.0 stars

**Reviewed by:** Verified User in Financial Services | Mid-Market (51-1000 emp.)

**Reviewed Date:** May 09, 2023

**What do you like best about Email on Acid?**

It is affordable based on how many seats you need. The service is straightforward. It helps my team catch issues before campaigns are launched for the public. Offers more tools than builtin services from customer engagement platform

**What do you dislike about Email on Acid?**

Unreliability in the platform. There are often issues with the QA tool, where I get an error and cannot proceed with my QA without resending the email to the platform. There are also issues with link validiation

**What problems is Email on Acid solving and how is that benefiting you?**

Email on Acid helps my team catch errors which benefits our goal of operation excellence. The spam headline tester is very helpful in the rare instance where a headline fails multiple filters

  ### 4. Must have tool for all digital marketers

**Rating:** 5.0/5.0 stars

**Reviewed by:** Jay K. | Marketing Manager, Enterprise (> 1000 emp.)

**Reviewed Date:** October 13, 2022

**What do you like best about Email on Acid?**

The tool is straightforward to use.  It gives you all the data you need to test and improve your emails.  Running the email rendering test and tracking the email is simple and easy.  The cost of the tool is reasonable.

**What do you dislike about Email on Acid?**

I have not found anything I did not like so far.  I hope their email rendering test can be run quicker, but it is not so bad that I would give a negative feedback.

**What problems is Email on Acid solving and how is that benefiting you?**

We wanted to check what devices and browsers our email recipients use to open and read our emails.  We also wanted a tool that could generate tracking codes quickly.

  ### 5. This provides an easy way to view email formatting across devices and browsers.

**Rating:** 5.0/5.0 stars

**Reviewed by:** Verified User in Non-Profit Organization Management | Mid-Market (51-1000 emp.)

**Reviewed Date:** June 14, 2022

**What do you like best about Email on Acid?**

I most like how easy it is to use. Paste in your code, look at some images and you're good to proceed with your email communications to constituents with the comfort of knowing your email will look great.

**What do you dislike about Email on Acid?**

I wish there was a way to tweak code and then retest without having to create an entirely new document in the system. It's a bit time-consuming. And some of the preview images take ages to load.

**What problems is Email on Acid solving and how is that benefiting you?**

We have a massive email list and our users use all combinations of devices, browsers and email providers. Without Email on Acid, it would be impossible to be certain that recipients are getting the email as intended.

  ### 6. Email on Acid is top notch for email testing

**Rating:** 5.0/5.0 stars

**Reviewed by:** Verified User in Marketing and Advertising | Enterprise (> 1000 emp.)

  ### 7. Best platform for email rendering issues

**Rating:** 4.0/5.0 stars

**Reviewed by:** Ahtesham H. | Developer Advocate, Small-Business (50 or fewer emp.)

**Reviewed Date:** January 24, 2022

**What do you like best about Email on Acid?**

It allows me to check how our email renders on different devices and platforms. It has helped save tons of time and effort for my team and myself. I really like the ease of use it offers.

**What do you dislike about Email on Acid?**

Not much to complain about here. It gets the job done with relative ease. However, sometimes, the previews take way too long to be generated when you update the HTML and resubmit the preview.

**What problems is Email on Acid solving and how is that benefiting you?**

It lets me create HTML emails and test every edit in real-time. I am able to check email compatibility with most popular devices and clients. A revision history tool helps me find and fix HTML issues going back to a previous version of the template.

**Reviewed by:** Praveen K. | Project Manager, Mid-Market (51-1000 emp.)

Good tool to do email previews. It has inbuilt features to check image size, URL checks, Spelling errors and Spam blocks. This is very useful.

Email test profiles can be created by an individual but can not be applied at the project level.

Good tool to test email previews.

  ### 10. Great Email Preview Software With a Few Caveats

**Rating:** 4.0/5.0 stars

**Reviewed by:** Verified User in Computer Software | Mid-Market (51-1000 emp.)

**Reviewed Date:** November 30, 2021

**What do you like best about Email on Acid?**

Email on Acid is more reasonably priced than competitors like Litmus. There are limited delverability check tools available in the Premium tier of service. Email previews appear quickly and new IOS systems appear as a preview option soon after they ate released.

**What do you dislike about Email on Acid?**

Occassionally there are issues with IOS mobile previews appearing incorrectly in Email on Acid when comparing to a test email on the actual device.

There's also no way to send an email from Email on Acid to a test account. The email needs to be send from another client.

**What problems is Email on Acid solving and how is that benefiting you?**

Our email marketing team uses Email on Acid to preview all newly formatted marketing emails from the channel.

  ### 11. Vital tool for email marketers

**Rating:** 5.0/5.0 stars

**Reviewed by:** Verified User in Information Technology and Services | Small-Business (50 or fewer emp.)

**Reviewed Date:** May 06, 2021

**What do you like best about Email on Acid?**

Email on Acid is a great tool that helps us to ensure our emails look great no matter who receives them. It is a critical part of our email checklist and allows us to make creative and coding changes, pushing the limits of email design whilst removing any fear that this will cause havoc in certain inboxes (Outlook not looking at you!). There are many vendors that offer this solution but Email on Acid is very easy to use, constantly providing great education on email coding in general and transparent in their pricing.

**What do you dislike about Email on Acid?**

Sometime the email rendors take time to load - but that's just nitpicking.

**What problems is Email on Acid solving and how is that benefiting you?**

Before we used Email on Acid we were shooting in the dark (or dark-mode) on what our emails would look like across various email clients. To our shock and horror when we began to use it we realised that the great looking emails on our Macs or in Gmail were an absolute disaster on hugely popular email clients. Email on Acid has allowed us to ensure everyone can see our emails regardless of client, OS or device. The coding tool is also super useful for designing third party vendor emails where we want to remove any coding related to our Marketing Automation System.

  ### 12. The Go-to Email Rendering Platform for Small to Medium-Sized Business

**Rating:** 4.0/5.0 stars

**Reviewed by:** Verified User in Financial Services | Mid-Market (51-1000 emp.)

**Reviewed Date:** January 13, 2019

**What do you like best about Email on Acid?**

The price is much better than the leading email marketing testing platform. If you don't need all the bells and whistles--just multi-platform email rending--but still want to test an unlimited number of emails, this is the platform for you. 

**What do you dislike about Email on Acid?**

The renderings aren't always 100% accurate. It's important that you still test emails on your own devices. Ran into issues a couple times where Email on Acid displayed some inaccurate renderings and we were made aware of how the email looked by a recipient.

**Recommendations to others considering Email on Acid:**

For small to medium-sized businesses, Email on Acid is probably your best bet. Litmus may seen attractive, but it's very easy to go over your usage limits and email previews are restricted in the most confounding way. 

**What problems is Email on Acid solving and how is that benefiting you?**

Email multi-platform rendering. While many of the top email platforms have built-in rendering services, they aren't as comprehensive or they require more money to use. Email on Acid has filled this void in our email service provider, Salesforce Marketing Cloud, and reduced rendering issues across devices while helping the team develop better coding skills.

  ### 13. Email on Acid for Email Testing

**Rating:** 4.5/5.0 stars

**Reviewed by:** Verified User in Consumer Goods | Mid-Market (51-1000 emp.)

The analytics tool is a little buggy and doesn't always work quite right.

Being able to send an email to multiple browsers and devices, then check the results in "Projects" - where you can customise which devices and browsers you want to see, and hide those you don't.

**What do you dislike about Email on Acid?**

When sorted by "full thumbnail", the name of the device/browser is at the bottom of the screenshot. It would be easier to scan/see if it were on top.

How emails look across multiple different browsers and devices, and the ability to see things going wrong before sending a communication.

**Rating:** 0.0/5.0 stars

**Reviewed by:** Verified User in Marketing and Advertising | Small-Business (50 or fewer emp.)

**Reviewed Date:** January 29, 2021

**What do you like best about Email on Acid?**

The price compared to Litmus is competitive

**What do you dislike about Email on Acid?**

It doesn't actually pick up rendering issues and is missing key email clients. We have had 11 incidents in which campaigns have deployed which were perfect in email on acid - but we had complaints of rendering issues. We then took the exact same HTML and tested in Litmus and every single issues appeared.

**What problems is Email on Acid solving and how is that benefiting you?**

None - not really fit for purpose as so many rendering issues are not shown in the previews.

**Reviewed by:** Verified User in Non-Profit Organization Management | Small-Business (50 or fewer emp.)

**Reviewed Date:** May 05, 2021

**What do you like best about Email on Acid?**

It's a great time-saver and allows me to test platforms and emails clients I wouldn't otherwise have easy access to.

**What do you dislike about Email on Acid?**

All platform/client renderings aren't 100% accurate but those that aren't are only slightly off.

**What problems is Email on Acid solving and how is that benefiting you?**

Accessibility and consistency across devices, platforms, and emails clients. Outlook is always the most troublesome and this helps resolve issues much faster.

  ### 20. So easy and helpful to use!

**Rating:** 5.0/5.0 stars

**Reviewed by:** Verified User in Primary/Secondary Education | Enterprise (> 1000 emp.)

**Reviewed by:** K M. | Co Owner, Small-Business (50 or fewer emp.)

**Reviewed Date:** May 15, 2019

**What do you like best about Email on Acid?**

I get analytics I only ever dreamt of - right in my email client! You have to understand, I'm an email marketer, through and through. That was my first digital marketing job. Now that I'm a company owner, I still like to get into the weeds on the channel I know best. EOA let's me do that. Heatmaps, robust click tracking, really fast and really good render testing. It's got a whole host of tools.

**What do you dislike about Email on Acid?**

Nothing yet! Keep up the good development work, guys.

**Recommendations to others considering Email on Acid:**

Give it a try! It's cheap, and it adds heatmaps to your emails. If you're serious about performance, it'll pay for itself.

**What problems is Email on Acid solving and how is that benefiting you?**

Our main email platform has a lousy email preview tool, particualrly for email on mobile devices. EOA's renders are accurate and fast - and it adds a whole host of other tools!

**Reviewed by:** Verified User in Marketing and Advertising | Small-Business (50 or fewer emp.)

**Reviewed Date:** September 26, 2019

Love it when we can see how our email looked in different email browsers.  Also, love the in program coding section, They also have a section where you can use pre-tags for HTML or you can set your own so you do not have to type out everything single time.

**What do you dislike about Email on Acid?**

Getting results from test can sometime be a bit slow but not always.

Email on Acid is a good alternative to Litmus.  Gives you the option to code and see your work being adjust at real time.

I love that it gives so many different views and makes our testing process so much shorter. Being able to mass review and fix and update has made our custom emails so so so much better. I love how many different devices and browsers you get to view. 

**What do you dislike about Email on Acid?**

The only thing I don't like is occasionally it shows you something that isn't actually occurring on the actual device. It also doesn't give a good idea of how it works with a touch screen device. Also sometimes the load speed is too slow for the image and you don't get a clear picture. Overall tho way more helpful than missing pieces. 

**Recommendations to others considering Email on Acid:**

This product makes testing and preparing emails so much simpler. It really adds value to a business and makes sure you actually are sending readable emails to your audience no matter what device or browser they use.

**Reviewed Date:** October 19, 2018

I love the ability to test my emails in multiple clients to ensure they present properly. We have an older client base using a wide variety of clients which requires extensive testing.

**What do you dislike about Email on Acid?**

The user interface can be a bit daunting and takes a bit of patience to get comfortable using.

It is great to be able to see how my email will look across all devices.

It allows us to test the responsiveness of emails across all platforms without having to have all of the platforms. It is really nice to have it all in one place to see where things are correct and incorrect.

  ### 31. Great Email Preview Tool

**Rating:** 4.5/5.0 stars

**Reviewed by:** Kristen W. | Marketing Manager, Telecommunications, Enterprise (> 1000 emp.)

**Reviewed Date:** December 27, 2016

**What do you like best about Email on Acid?**

I like the ease of use, the fact that you can just send to 1 email address every time and not need to add a new contact to your email automation tool each time, and the great analytics. There is also a plugin to Eloqua which is super helpful and convenient. I also like it that we can all login and see each others tests for additional quality control. 

**What do you dislike about Email on Acid?**

The spam test requires you send to a seed list, I wish it was run with the preview and other testing. 

**What problems is Email on Acid solving and how is that benefiting you?**

This helps us to make sure our emails look good on all platforms as well as increase deliverability. It also can help you when building your emails. We use templates but this is helpful when making changes to them, especially for people who are not as familiar with HTML.

  ### 32. Nice and easy way to test email confirmations on different platforms

**Rating:** 4.5/5.0 stars

**Reviewed by:** Elena R. | Project Manager, QA Specialist, Computer Software, Small-Business (50 or fewer emp.)

**Reviewed Date:** October 27, 2016

**What do you like best about Email on Acid?**

What I like about Email on Acid is its simplicity. We just set up our email confirmations to go to specific Acid's email and as a result we are able to do cross-platform and multi browser testing for web and mobile. This is a very useful tool for front-end development and quality assurance in terms of emails testing. 

**What do you dislike about Email on Acid?**

There are not many things that I dislike about Email on Acid, but the one I can think of at the moment - when it generates previews of email for all devices and browsers some of them can take a while (e.g. 5 minutes or more) and I don't usually wait for all the previews being generated. But most popular devices and browsers are generated just fine.

**Recommendations to others considering Email on Acid:**

If you are concerned about every little detail, Email on Acid is definitely a tool for you to use. They have a free trial and you can always try it free before deciding if this is the something you are looking for.

**What problems is Email on Acid solving and how is that benefiting you?**

We have multiple web and mobile applications that generate emails. Mostly it's email confirmations that customers receive when an order is made, but also there are registration emails and even marketing campaigns. It's important for us that when a customer checks out his/her email from us, this email looks nice and neat. And Email on Acid in a few simple steps helps us to achieve this goal. I would definitely recommend it to a friend.

  ### 33. EOA makes your emails GOOD

**Rating:** 5.0/5.0 stars

**Reviewed by:** Andrew P. | Senior Product Marketing Manager, Customer Intelligence, Mid-Market (51-1000 emp.)

**Reviewed Date:** March 19, 2017

**What do you like best about Email on Acid?**

Digital marketers know the reach and power of email, but quality analytics, development and testing is lacking from email campaign services. EOA does email creation and monitoring. That's it. And they continuously offer more.

**What do you dislike about Email on Acid?**

I wish the analytics had better reporting and aggregating tools.

**What problems is Email on Acid solving and how is that benefiting you?**

We know how or emails perform. We know reliably what's opened and clicked, for how and on what devices. We put more time and resources into more emails because we've seen their full benefit.

  ### 34. Invaluable for all aspects of email testing

**What do you like best about Email on Acid?**

If you're sending emails of any kind, a testing tool is vital to your workflow, and Email on Acid is one of the best options available. It has all the essential features you need, including image previews, link checking, spam testing, and an email builder. All of them work quickly and flawlessly, and a clean interface allows easy navigation to the different tools.

On top of all the basics, Email on Acid goes above and beyond with their unique link map tool that visually displays where all hyperlinks are within an HTML email and lets you know if they're working or not. It also includes an extremely powerful code analysis tool that displays warnings about unsupported tags or other HTML and CSS features in emails.

Email on Acid is especially helpful when working with clients and colleagues. Its share feature allows you to send a link to a third party that displays all of the important information about an email test without having to set up an account for them or bogging them down with more features than they need.

**What do you dislike about Email on Acid?**

There is honestly not much to dislike about Email on Acid. It does everything that you would expect from an email testing platform and more, and it does it at a lower price point than any comparable competitor. The only reason I can think of not to use Email on Acid is if your ESP already includes testing tools, but it is likely that bundled tools are not as robust as a standalone platform.

**Recommendations to others considering Email on Acid:**

Make sure you take advantage of the code analysis and spam checking features. If you use these diligently and take what you learn to heart, your emails will improve precipitously over time.

**What problems is Email on Acid solving and how is that benefiting you?**

Email on Acid can save tons of time and headache when troubleshooting HTML email design. It is the easiest way I've found to do a comprehensive test on any message before sending, and it's saving us money by offering a more affordable option that similar tools.

  ### 35. Great Email As a Service Platform

**Rating:** 5.0/5.0 stars

**Reviewed by:** Hector Antonio C. | Software Engineer, Internet, Small-Business (50 or fewer emp.)

**Reviewed Date:** March 27, 2016

**What do you like best about Email on Acid?**

I used ConstantContact before I found Email on Acid, and their templates and customer support is by far superior. I really like how most of their designs are very responsive to mobile and web, and how they follow design trends very closely. Most of my emails have great read and click rates due to these features.

**What do you dislike about Email on Acid?**

Sometimes I realized that ConstantContact has better integration when sending mass emails and the time consistency when users get them; also, predictions on best times and unsubscribe features are better in other platforms (Constant Contact). Other than that, Email on Acid is probably the best email service I've tried.

**Recommendations to others considering Email on Acid:**

Their pricing is more competitive than other email services out there, which makes it very attractive. Plus, their customer service and designs are prime.

**What problems is Email on Acid solving and how is that benefiting you?**

I need to communicate with my user base, whether they make a transaction, submit information, or subscribe to the weekly bulletin on my web app all communication is done through email.

My favorite part is that Email on Acid emails you the test emails so you can easily see what it will look like in several different email clients.

Sometimes, some of the email clients just don't show up. The test malfunctioned or something.

I'm able to test my emails in other email clients (besides my own) relatively easily so I can make sure my email will look right (or as close to it as possible) in everyone's inbox.

**Rating:** 4.0/5.0 stars

**Reviewed by:** Josh M. | Email Marketing Manager, Marketing and Advertising

**Reviewed Date:** September 25, 2013

**What do you like best about Email on Acid?**

I like the usability of the product as well as the valuable information they provide to their users as well as on their blog. I always pay attention when they publish content about email marketing. 

**What do you dislike about Email on Acid?**

It would be nice if you could engage with your content as if it was live on each platform, but I realize that their system is simply focused on the rendering of the content rather than the full user experience in each platform. This isn't a major dislike, it is simply the only thing I could think of. 

**Recommendations to others considering Email on Acid:**

It is an amazing resource to make sure that your brand/content is being represented well in all platforms. This makes my life a lot easier.

  ### 43. My New Favorite Email QA tool

**Rating:** 4.5/5.0 stars

**Reviewed by:** Mark H. | Director, Sales and Marketing Technology, Mid-Market (51-1000 emp.)

**Reviewed Date:** December 31, 2012

**What do you like best about Email on Acid?**

Its quick and easy - when you're performing QA on email you want results quickly so that you can test and make adjustments. EOA does this better than any other solution that I've used (I used to use Litmus, but I find EOA more responsive and more stable). Right now you can review how your email looks on over 68 clients and mobile devices. And its much faster than the Return Path solution I've used integrated into Eloqua.

I also like the ability to cut and paste as well as send email from my ESP or marketing automation solution.

**What do you dislike about Email on Acid?**

I wish it would recognize the subject line when you send an email in for testing.

**Recommendations to others considering Email on Acid:**

If you've never used a QA tool for email validation, this will change your world.
