9 Best Email Testing Tools to Preview Your Newsletters

Best Email Testing Tools

An email campaign is a time-proven way to engage your audience, remind them about your brand, keep them updated, sell your products and services, and establish close relationships with your users. It is a powerful tool that, when used right, benefits your company and reinforces its online presence. Yet, email campaigns won’t reach their full potential without the help of powerful email testing tools.

Why You Need an Email Testing Tool

The success of your email campaign depends on multiple things. There are many parameters to monitor but first and foremost, you need to ensure that your email newsletter works as it’s intended. Newsletters are the core of every email marketing strategy; they are one of your most important communication channels with your audience.

Before starting to examine metrics such as bounce rates, click-through rates, or ROI, make sure that your HTML newsletter actually delivers the content. You need to check several things such as if:

  • the content is displayed correctly,
  • all the visuals have alt tags,
  • the markup looks consistent in all popular email readers and devices,
  • and many others.

The best way to achieve all these objectives is to put an email testing tool into use. It will check the copy of your newsletter, show all the errors and issues, and provide you with crucial insights about how to make your newsletter better.

The Best Email Testing Tools

Email testing tools show you how your HTML newsletters look like in different email clients. In this way, you can make the necessary changes and improvements before sending the emails to your users, and avoid catastrophic outcomes.

1. HTML Email Check

HTML Email Check

The very first tool in our collection of the best email testing tools is called HTML Email Check. Unlike all the other tools featured in this list, it’s not primarily an email testing tool but an email markup validation tool. HTML Email Check validates your HTML and CSS markup, images, links, fonts, and other assets. Although checking the source code is more of a developer thing, it’s still vital for the success of your campaign.

For example, HTML Email Check points out all the missing alt tags in your code. And, this is a huge thing, since alt tags get your back when your user’s email client doesn’t support images. The alt tag helps your subscribers still get the message hidden inside your images and make your newsletter accessible to screen reader users, too.

2. Litmus

Litmus

Litmus is one of the best email testing tools, famous for its professional solutions, helpful tools, and comfortable environment for non-tech-savvy users.

In addition, it comes with numerous checklists, built-in email analytics, spam testing, and other features.

3. Email on Acid

Email on Acid is probably less powerful than the previously mentioned Litmus, yet it is a perfect solution for small-scale campaigns and companies with a shoestring budget. You can easily preview your newsletters on desktop, tablets, and mobile phones, as well as in different email clients.

4. Preview My Email
