Why You Should Care About Email Testing



Most businesses still see email marketing as the most cost-beneficial and conversion-rich way to develop relationships with potential customers or clients and promote their products or services. What makes it such a powerful tool?

The numbers speak for themselves. A recent study holds that the median email marketing ROI is 122 percent. So far, no other digital marketing channel has proven to show such high results. Of course, the best way to boost your performance is to combine email marketing with social media or enable a live chat, which is statistically the fastest option to communicate with customers. But we’ll focus on improving email marketing efforts through email testing in this article.

When you run an email marketing campaign, creating emails that focus on your targeting audience and align with your marketing goals takes a lot of researching and strategizing. It’s a good idea for every email marketer to do email testing since it directly impacts the quality and deliverability of messages and indirectly ROI and subscribers retention.

Let’s take a closer look at email testing best practices.

What is Email Testing?

Email testing allows you to view your email before sending it out to your subscriber list. Many email marketing services offer a way to preview the email in a web app or send a test email to yourself.

Testing your emails will help you fix broken email designs, incorrect or untracked links, choose a subject line with higher open rates, eliminate spelling and grammar errors, broken images or missing alt text, and more.

Let’s view seven elements that you should consider testing.

What Elements of My Emails Should I Test?

As we’ve mentioned above, you shouldn’t test more than one thing at a time to clearly see what’s really impacting your results. Choose one and measure against this metric in all your tests.


Subject Line

The subject line is crucial for your email campaign because this is what your recipients see first and decide whether they’re reading your message or not. You might have noticed that the subject line is formatted differently on most devices – it stands out due to email clients, display size, font difference, etc.

Your subject line should be catchy and interesting. At the same time, it shouldn’t sound spammy or violate email etiquette, failing which it will end up in the spam or junk folder.

  • Bad Example: Here’s a FREE Newsletter with top articles! 🔥🔥🔥🔥🔥
  • Good Example: John, February must-reads for you

Length of your subject line

Subject lines of 61 to 70 characters have the highest average read rate. However, the only way to determine the most compelling email subject line length for your campaign is to test it.

It’s a good idea to run an A/B test during every campaign and find out what subject line length gives better results.


Personalized emails actually work. The recipient’s name included in the subject line can increase opens by over 18 percent, making it the most impactful word you can add to your subject line.

Try A/B testing it for your next email campaign. For example:

A: John, enjoy 50% off using this discount code


B: John, what about a great discount?

Microsegmentation is a good way to boost your personalization efforts. Try using a more diverse segmentation, experimenting with focused lists of users to deliver the most relevant content and offers.

Alternatively, you can try referencing the recipient’s previous orders, their company name, state, or choose other types of personalization.

Everyone is talking about the importance of quality content, but do you fully understand what content brings to your emails?

When you find out which content format works best for your newsletters and other emails, you will easily choose the resources for similar recipients in the future and use the most suitable email template.

Here’s what you can try linking out to in your messages:

  • Case studies vs. Demo videos
  • Blog articles vs. webinars
  • PDFs vs. PowerPoint presentations
  • Reports vs. Whitepapers

Media Elements

You can substantially increase your email performance by including the images, GIFs, videos, and other media elements that resonate with your recipients.

Before testing your emails, make sure you use similar alt and title text behind the media.


Some email clients don’t load media files, and in such cases, the alt and title text can make a big difference.

Keep the data in your test clear and avoid any changes in alt or title tags.

Here’s another option. When you run your test, start with placement or density and move on to image type or color.

If you have already experimented with images and GIFs, you should consider integrating video marketing in your email efforts as a solid way to increase brand awareness, improve sales, and increase customer engagement.

Day and Time

Be aware that you should run your day and time tests more than once. Some factors may keep your recipients offline: ISP slowdowns, holidays, or various unexpected events.

Before getting your final answer, try running your date and time test several times to make sure nothing impacts the data and your definitive answer.

Currently, due to the pandemic effect, user behavior has changed. As a result, such unpopular days to send marketing emails (Fridays and Saturdays) have become good alternatives to overused days (Tuesdays and Thursdays.)

When sending a newsletter, consider at least three day and time scenarios:

  1. Traditional: Tuesday or Thursday to be delivered at 1-3 PM
  2. Experimental: Wednesday to be delivered at 11-12 AM
  3. Extraordinary: Friday to be delivered at 9-11 AM or Saturday noon

Promotion and Special Offers

Nowadays, offering massive promotions several times a year is considered a new normal for generating customer interest. In fact, 91 percent of consumers are more likely to do business with brands that provide them with relevant, personalized offers and recommendations.

However, a popular promotion can end up costing a lot of money, while an offer that wins a lot of responses can bring you a considerable profit.

Keep in mind that some segments of your list may respond to one type of offer better than to a different kind of offer and promotion. There isn’t a “one size fits all” type of offer, and it’s a good idea to run a test with different propositions to different segments.

Once again, timing plays a central role here and may be crucial for the success of your offer.

Consider running an offer test several times, as you want to make it at a time when a product is popular and your audience is ready to spend money. Experiment with abandoned cart emails and re-engagement campaigns.


Is it possible to engage your recipient with just a tone? Psychologists say that by incorporating positivity into your message, you make it much easier for your reader to understand your message. This clear understanding, in its turn, increases their motivation to make a purchase or continue communication.

Think about your target reader and try to come up with a tone that would be friendly, positive, and informative at the same time. Do A/B testing of the email body to find which works best. It takes time, but it would definitely boost your click-throughs and purchases.

Tactics to try:

  • Read aloud your message and ask a colleague for a check.
  • Use bullet points and break the message into subsections.
  • No big words are needed.
  • Be simple, be friendly.
  • Cause emotions.
  • Ask questions (no more than three).

It’s important not to be gray in your emails. Don’t skip testing tones, polishing emails that will engage your audience best.


A call-to-action in an email is a button, hyperlink of text, or dynamic QR codes that motivates the user to take the next step. You need to use strong call-to-action phrases to push your reader to click and proceed to your website before closing your email.


Additionally, CTAs have a great value for marketers, helping them evaluate their digital marketing campaigns’ effectiveness, analyze their target audience’s needs and preferences, and decide about the next step of the campaign.


How Should I Do All This Testing?

After the outlined practices you should definitely try in the next campaigns, a reasonable notion pops up: how to test all those elements. Fortunately, there’s a variety of tools and solutions that will assist you greatly.

Content Elements

  • With all the A/B testing features, solid reporting, and the ability to preview your emails and make tweaks in content, consider choosing Benchmark Email.
  • To improve the copy as well as the tone of your emails, feel free to use Grammarly or Hemingway.
  • For evaluating and polishing subject lines, you can try out SubjectLine (we love a tool that’s straightforward in more ways than one).

Tech Elements

In this field, you definitely have to ensure your emails reach users, deal with spam rates, and do HTML checks. You can use all-in-one platforms for safe technical testing of your emails like Mailtrap or similar.

Alternatively, you can choose tools focusing on some aspects of such inspecting and debugging. For example, if you need to check spam rates only, there are tools like MailTester, or if you need to validate emails – EmailVerifier by Hunter will help.

At some point, you may need more tech-savvy tools for testing, say, API integration or configuring SMTP; feel free to check this email testing checklist article to know more.

When it comes to user-behavior aspects, like special offers and day/time testing, it requires a deep understanding of your audience and a bit of courage to experiment with it. So, to test these elements, constantly analyze and document the outcomes from previous campaigns.

6 Tips for Effective Email Testing

  1. Keep it simple. When testing your emails, it’s a nice idea to start with testing your subject lines. You don’t need a lot of time or creativity to contrive a few quick variants; however, this may give you a good return.
  2. Don’t test more than one element at a time. Remember, if you test several elements simultaneously, you may get confused over which variant worked out.
  3. Keep track of the time of day and day of the week. Send other variants on the same day and at the same time. This way, you will eliminate the timing variant.
  4. Keep a record of all tests you do. Leave the possibility to review the specific variables tested anytime you need to by always recording your findings.
  5. Test on a regular basis. If you decide to start testing your emails, make sure that email testing is a part of your daily routine.
  6. Make good conclusions and act wisely. Email testing will allow you to make decisions and modifications to your campaigns only if you analyze your findings and properly use what you learn.

Let’s Say it Again!

Email testing is an effective way to transfer your marketing effort into real results. Of course, the goal here isn’t to make your entire team focus on email testing but to get better results using the tips above and the tools below.

What do you start from? Understanding of your needs. Before running your first test, make sure you clearly understand what you’re doing it for and what results in your plan to generate from the process. And choose the correct solution.

Once you are set with your priorities, create a hypothesis. For example, “if we personalize our newsletter, our blog traffic will substantially increase.” You’ll need to determine the kinds of tests you’ll need to run to check whether your hypothesis works. Put together a timeline for easier scheduling, management, and organization of your testing process.

What Not to do in Email Marketing



What Not to do in Email Marketing

Email marketing is one of the best ways to speak directly to your audience. You can build a relationship with them and create loyal customers. It is also a great way to generate traffic to your website, increase leads, and execute large campaigns.

With all of the benefits that your company can gain from email marketing, it’s no wonder that 64% of small businesses engage in email marketing. However, there are still a few important things to keep in mind. In order to be successful, you should avoid these 4 mistakes explained by 97 Switch when preparing an email marketing campaign.

Talk About Yourself

Many companies fall into the trap of only talking about themselves. They assume that since their audience signed up for emails, they want to hear all about the company and the sales. While marketing your products or services is important to do sometimes, your audience is still looking for value.

Failing to foster a relationship with them by being too sales-y will lead to unsubscribers and a loss of potential customers.

Instead, it’s important to give the audience something in return for their loyalty. Exclusive deals and sales codes are appreciated, but they also want to see educational or entertaining content in their inbox.

One way to do this is by creating content such as “you asked, we delivered” or “your questions answered” to show that you care about your customers and the feedback they give you, and it builds trust.

It’s also important to speak your audience’s language. Sometimes, companies get too caught up in trying to sound professional and impressive and end up using jargon that’s hard to understand.


Using more simple ways to get your message across is imperative, as it makes the email easier to consume and thus more valuable.

Email Without a Purpose

While building relationships with your customers is one of the main goals of email marketing, you should keep in mind that they don’t want to hear from your company just for the sake of connecting.

Ensure that you have a clear purpose for each email you send, whether that be to inform, entertain, or motivate.

Being intentional about when to reach out includes sending timely emails. You should respond to relevant industry, company, or world news in a timely manner. Readers would find you reminding them about the last day of a sale important, and that qualifies as a purposeful email.

Part of proceeding with a clear purpose is also including a call to action in your emails. Your readers want to know exactly what you’re asking of them, and making it simple is the best way to get it. Beware of including too many calls to action, as it can be more confusing and seem more selfish than helpful.

Over Generalize

Personalization is one of the greatest strengths of email marketing, yet it is often overlooked. Simply including first names in an email makes it sound more personal and builds stronger relationships. This can easily be achieved using an email scheduling tool such as Mailchimp. Again, this is a way to build customer relationships. Research shows that using someone’s name in the subject line increases open rates by 26%. Be that as it may, personalization is more than just plugging in names.

Using an email marketing tool is also an easy way to utilize the segmentation aspect of personalization. By separating your audience into groups, you can categorize what they would each be most interested to hear from you.

It has been shown that segmented campaigns perform better than non-segmented campaigns. An example of this is categorizing your readers as beginners, intermediate, or advanced knowledge of your industry. Based on this category, you can send each segment a different email that would pertain to them more specifically.


Your readers will appreciate that your content is tailored to their needs. Imagine sending a beginner an email that skips over the basics of a process. They would be confused and find it very unhelpful.

Now imagine an expert who is wasting time reading the basics that they know by heart. They would become frustrated and lose interest in finishing the email. These are just two examples of using segmentation to better serve your audience.

Use Poor Subject Lines

Often, people will decide whether to open an email at all based on the subject line alone. A mistake that marketers tend to make is wording the subject in a way that sounds like spam, and thus never gets opened or reaches the audience.

As we mentioned before, it is also helpful to include someone’s name in the subject line. While it might seem like a shot in the dark to form an effective subject, there are a few tips for the best open rates you can achieve.

A good subject line should be short. The ideal length for a subject is 7 words, based on a study conducted by Marketo.

However, you also want to make it interesting so that people are curious and want to know more. This curiosity is enough to encourage people to read the email.

However, you want to avoid click-baiting your readers with interesting subject lines that have nothing to do with the content in the email. Make sure that your subject is also relevant to what you have to say. Otherwise, you will have the opposite effect you’d intended by destroying trust and losing credibility.

Being Inconsistent

Simply sending out random emails is not enough to see results. You have to stick to a schedule that your readers can count on and know when to expect to hear from you in their inbox.


The frequency can vary based on your industry and from business to business, but emailing at least once a month is recommended. The more you email, the more you will be on the top of potential customers’ minds when they need what you offer.

That being said, you shouldn’t always assume more contact is better. If your company emails are flooding their inbox, you can bet that they will either block the sender or unsubscribe from future emails. Finding a balance is key to seeing the best results from your campaigns.

You should also consider the brand voice that you are using to speak to your customers. If your emails all sound like they were written by different people, then it’s hard to gain the brand-strengthening benefits of email marketing. It is also confusing to your audience and makes it harder for them to connect with the company.

A good way to remedy this is to create a company persona, where you give a personality to the company that is sending the emails.

Are you funny and witty, or are you serious and somber? Consider strengthening your branding within the company before communicating it with the world.

Key Takeaways

You can’t expect to be perfect at email marketing, so don’t get discouraged if you find that you have made these mistakes. There is always room for improvements, and every so often it’s a good idea to evaluate how your email marketing campaigns are going.

Using analytics to track your results and adjusting your strategy will help you grow as you fix any mistakes you might be making.

By taking the time to improve your strategy, you will see the success that can carry across all your marketing efforts.
