Table of Contents

Every business owner in 2021 knows the power of an effective email campaign and understands why email marketing is important. As a result, many of them now look for agencies that offer reliable email marketing services. From advertising to coupon codes—and even digital receipts and shipping information—ecommerce and online organizations rely heavily on proper email marketing.

That’s why it’s paramount to make sure your email communication is reliable. 

When glitches, typos, and other mistakes occur on a massive scale, they can significantly hurt your company’s reputation. This is why digital organizations must prioritize email testing. Read on for four of the best email testing tools currently on the market!

What is an Email Testing Tool?

There are many reasons to use email testing software. First and foremost, these digital tools allow companies and organizations to send out mass emails without wasting time typing addresses manually while increasing sender reputation. 

Email testing tools are also programmed to follow the anatomy of an email, check for spelling and grammatical errors, as well as prevent emails from being labeled as spam. 

The testing tool also lets you easily create a template and send out test emails. For customized layouts, email testing tools allow companies to get an inbox preview and how their message looks before sending it out to their client.

Overall, using an email testing tool can help you boost productivity, avoid mistakes, and ensure you send the right emails every time. Taking these precautions is a crucial step toward increasing your brand’s professionalism and visibility.

The Best Email Testing Tools Available

Now that you understand the importance of email testing tools in your marketing campaign, it’s time to dive into the real question at hand: Which one is the best? While every company will have unique marketing needs, we’ve laid out four of the best email testing tools, how much they cost, and what features they include. Let’s take a look:

#1 Litmus

One of the most common email testing tools in the digital marketing industry is known as Litmus. Many high-level companies and organizations prefer litmus due to its:

  • User-friendly interface
  • Productivity and data tracking tools
  • Customizable features
  • Pre-send quality checks
  • Perform email spam test
  • Seamless integration with any mail server

Customers can test out Litmus with a three-day free trial. After this period, you’ll have three options for pricing plans:

  • Litmus Basic – The most affordable paid plan that Litmus offers is the $99 per month Basic plan. This option is designed for smaller businesses, particularly those with a one-person email team. With the Litmus Basic plan, you’ll get one complete user profile, unlimited read-only users, and up to 1,000 email previews. 
  • Litmus Plus – The Litmus Plus plan will work best for slightly larger organizations catering to several different clients, with two or three person email teams. For $199 per month, customers who opt for the Litmus Plus package will get five complete user profiles, unlimited read-only users, access to the spam testing tool, and up to 2,000 email previews. 
  • Litmus Enterprise – The final option Litmus offers for their email testing plans is called Litmus Enterprise. This package is designed for large companies with email teams of four or more employees. Pricing for this plan will vary due to its customizable options, such as the number of full user profiles and email previews.1

Litmus can also adjust these prices for customers who select an annual payment plan. When you pay for your Litmus subscription a year in advance, you’ll receive 20% off the total purchase.

In addition to its original services, Litmus also acquired the popular email testing platform PutsMail. PutsMail is an excellent option for smaller companies because it actually offers a free tool for sending emails. While PutsMail can help you save money, it’s important to note that their manual email address input will be less efficient than a paid Litmus plan.2

#2 Get Response

Get Response is another popular email testing tool, mainly due to its lengthy 30-day free trial. With Get Response, users can utilize several helpful email marketing tools, including:

  • Newsletter scheduling
  • Email response automation
  • Transactional emails, such as receipts and purchase confirmations
  • A drag and drop email creator for custom designs
  • Layouts, templates, GIFs, and stock images available to use3
  • Easy integration with multiple mail server

Once the 30-day free trial is up, Get Response offers four different options based on your company’s needs, although prices will vary depending on the size of your mailing list. Below is a breakdown of each plan:

  • Basic – The Basic plan is Get Response’s most affordable option. This plan includes email marketing, autoresponders, unlimited landing pages, and templates, and even feature Facebook and Google advertising tools. Prices will vary depending on the size of your mailing list. For company’s with a small mailing list of 1,000 recipients, pricing for the Basic plan starts at $15 per month. This cost can go up to $450 per month, however, for mailing lists of 100,000.
  • Plus – Next, we have Get Response’s most popular option: The Plus plan. With the Plus plan, you’ll get additional marketing tools, including up to five automation builders, webinars, and contact scoring and tagging. Pricing for this plan ranges from $49 to $499 per month.
  • Professional – With the Professional plan, customers will have access to advanced email marketing tools. Benefits of this plan include unlimited automation builders, web push notifications, and paid webinar services. The price of this plan ranges from $99 to $580 per month.
  • Max – Similar to Litmus, Get Response also offers a customizable plan. With this option, users can add different features based on the size of their company. Common add-ons include transactional emails, customer support services, and team and role management. The pricing for this plan will vary depending on what’s included.

If you’re interested in saving money on your subscription, Get Response offers deals when you pay in bulk. Users who select annual pricing will receive an 18% discount, while those who pay every two years will get 30% off their total.4
