Tutorial: How to Begin A/B Testing Email Designs

Want to know which email campaigns catch your readers' eyes? Try this easy solution: A/B testing.A/B testing compares two versions of the same thing (subject headlines, email design layouts, CTA buttons, etc.) until you narrow down results for comparison. Not surprisingly, the data that results from the A/B testing is powerful, from open rates to click-through rates to conversions, and reveals howyour audience responds to changing variables. It's a great testing and optimization method to understand your audience's reaction to changes in calls-to-action, layout, and background color.Today, we'll be using Beefree to walk you through how to conduct A/B testing on your email design.

How to decide what to test

Before designing your A/B campaign, determine what you want to test. To start, choose just one variable so your results are clear. Here are some examples of commonly tested variables:Design

  • CTA size and style. Full-width button or smaller? Green or red? Tall or short?
  • Layout. Single column or multiple?
  • Color scheme. White or gray background? Blue or green header text?
  • Image size or variety. Two product images or four? Still image or animated GIF?
  • Information amount. Include secondary content or not? Social media buttons or not? Nav menu or not?
  • Information placement. Social buttons at the top or bottom? CTA button mid-way through or at the end?

Content and Time

  • From line. Your business name or the name of an individual?
  • Subject line. Shorter or longer? Emoji or no emoji? Include "" language or not?
  • CTA language. "Claim your ebook now" or "Claim your free ebook"?
  • Body text. "Pushy" language or more subtle? Six sentences or three?
  • Send time. Will there be more opens at 8:00 AM or at 4:00 PM?

Best practices for A/B testing

As you prepare your campaign, do your research and be sure to follow some best practices, including:

  • Determine your success metric first. Open rates will make sense if you're testing subject lines; click-through or conversion rates for design changes. Know what you're evaluating in advance.
  • Test only one thing at a time. If you change more than one variable, you won't be able to tell what caused the change in response.
  • Test a big sample size. Understand how many responses you need to show statistical significance.
  • Send A and B versions at the same time. Time is a variable, so be consistent by having both campaigns be sent at the same time (to different groups)—unless send time IS your variable.

Today's Workshop: How to A/B test email design changes

Let's walk through how to A/B testing related to design by using this email example fromVerywell, a site that provides health advice and resources.

Verywell A/B testing

A/B Design Test 1: CTA button

Verywell'scurrent version of the email has no call-to-action button. What if we added one in the first module to see how it changed the click-through rate?For the "A" version: Let's first recreate the Verywell email as-is in the Beefree editor. Using the drag-and-drop functionality, the basic email outline from the Structure menu can be pulled, followed by the appropriate content blocks and content. Here's the first half of the email, i.e. our part "A" of the test:

Verywell A/B testing CTA button

For the"B" version,simply drag a CTA from the Content menu and format it.We chose a button that matches the header color, is nearly the width of the email, and uses some urgency in the text, "Check out the recipe now." So will this CTA increase clicks? Well, we'll just need to send our A/B test emails to find out!

Verywell A/B testing CTA button

Just a note: In Beefree, it's easy to save your email and edit it later. Look for the blue "Save Message" button in the upper right corner. This way, you can create one version—like your "A" version—and save it to edit later.

But the important thing to know about A/B testing is: you can also copy an entire email in Beefree to make modifications to your "B" version and save it. Look for the "Create a copy" command in the "Edit Message" drop-down menu. Creating a copy means you won't have to start from scratch to create a second version.

A/B Design Test 2: Layout

Without multiple columns, but how would Verywell's email perform if a version included the first module as a single column?Instead of arranging the header text and image side-by-side, let's update the layoutso the image appears above the text.Using Beefree's drag-and-drop functionality, changing the layout is super simple. Starting with the "A" version, we'll drag in a single-column structure as a destination for our content:

Verywell A/B testing layout

Then, grab the existing header text, and drag it down:

Verywell A/B testing layout

Finally,grab the image and drag that underneath the text:

Verywell A/B testing layout

That's it! The text re-flows and image resizes, so our email is automatically formatted nicely. Now, we can delete the empty two-column structure, and the new email is ready to go:

Verywell A/B testing layout

A/B Design Test 3: Background color

Even thoughVerywell's email has a nice, clean look with an all-white background, how would readers react if the first module has a bight background color that matches the brand's teal color?To change the background color, let'sselect the top row, then navigate to the Structure menu and update Content background. 

Verywell A/B testing BEE Pro color change

After that, let's update the text from black to white to make it readable, and our new module is ready to be tested:

8 Common Email Spam Triggers That Can Damage Your Sender Reputation

In 2024, roughly 361.6 billion emails were sent per day. Whether you're using email for business or to keep in contact with your long distance cousin (do people still do this?), it’s easy to picture just how clogged someone's email can get. That's where modern day Email Service Providers (ESPs) come to save the day with trigger-based spam filtration tools.

For user these spam filters help ensure a smooth email experience, free of spammy and fishy emails. However, as email marketers, these filters lead us to be overly cautious out of fear that our emails are not accidentally filtered out.

Whether you’re employing a lifecycle email marketing strategy or simply confirming an order, we’ve outlined the basics of how spam prevention works, why it matters, and how to avoid running afoul of some commonly used triggers.

Why you need to avoid email spam triggers

Whether you’re an ESG reporting software or a travel company email spam triggers can email marketing performance and in turn hurt your business. For one, there’s the obvious reason that if your emails get sent to the spam folder, they probably won’t be seen. That's time and effort wasted.

Beyond that, being sent to the spam folder too many times delegitimizes your email marketing, which damages what’s known as your sender reputation. When just starting out, this reputation is effectively neutral. But if it gets too low, it could damage your marketing performance and even result in being blocklisted.

How email spam filtering works

As mentioned above, spam filters are implemented as a form of quality assurance and protection for end-users. Here's how ESPs determine content to be spam:

  • Sender reputation analysis: ESPs check sender reputation based on authentication, user complaints, bounce rates and sending patterns. They’ll also check the reputations of your IP address and web domain.

  • Content analysis: Content filtering uses triggers like keywords, formatting and error detection to distinguish spam from legitimate email marketing.

  • Blacklists: Along with sender reputation metrics, ESPs also cross-reference email senders against any of several blacklist databases. Being on even one of these means you’ll struggle to climb out of the spam folder at all.

8 common email spam triggers and how to avoid them

Now let's get to the good stuff. Prevention is generally the best strategy when it comes to avoiding email spam triggers. Here are seven factors commonly used by ESPs to filter spam emails, and the simplest solutions for dealing with them.

1. Lack of authentication

Missing authentication is one of the first red flags an ESP will pick up on. Authentication shows you’ve taken certain steps to establish legitimacy. It’s also used to prevent fraudsters from impersonating your brand online. There are three commonly used forms of email authentication:

  • Sender Policy Framework (SPF): This means publishing a list of mail servers and IPs with permission to send messages using your domain. This is one reason it’s important to conduct email marketing through a branded business email, rather than a personal account.

  • Domain Keys Identified Mail (DKIM): A cryptographic signature which shows a message’s original content has not been altered during sending. Think of it like the tamper-proof seal on a bottle of milk.

  • Domain-based Message Authentication, Reporting and Conformance (DMARC): A way for you to establish how you want receiving platforms to handle authentication failures related to your domain.

2. Shady linking practices

Link placement and presentation play an important role in email marketing. Aside from engaging recipients and securing click-throughs, using links appropriately helps avoid your emails looking like spam.

Questionable linking practices include:

  • Links to domains with poor reputations
  • Excessive numbers of in-email links
  • Compressed, modified or obscured links, particularly when generic link shorteners are used

Only link to your own authenticated domain. Also, use an unlimited bandwidth VPS to help ensure your website access speed is always stable and fast. This will give visitors the assurance that your site is legitimate.

Don’t forget to make the purpose of any in-email link absolutely clear.  

3. Content

Although the reason for an email landing in a spam folder is often related to authentication, reputation, or poor formatting, content can at times be the culprit. Here are elements that you should look at if you suspect that your content is why your emails are not reaching their recipients:

  • Typos
  • Irrelevant content that doesn’t foster positive engagement
  • Poorly translated text
  • Partner content with poor reputation
  • Possibly offensive content
  • URLs or images with poor reputation

Another thing to note is language detection filters. Various words, phrases and tone choices have strong associations with scam emails. This includes certain buzzwords, vague or exaggerated claims, or excessive sales jargon. However, this is only really an issue when you already have a bad reputation.

Nevertheless, let’s say you’re beginning to build your reputation back up and are conducting Black Friday email marketing. While it’s important to use engaging language and strong CTAs, you should avoid terms like:

  • Limited time only
  • 100% free
  • Make money from home
  • Avoid bankruptcy
  • You have won

4. Bounce rates

A ‘bounce’ is when an email doesn’t arrive in the recipient’s inbox. This could be due to it being sent to a fake email address, an out-of-date email that is no longer in use, a full inbox, etc.

When a sender frequently experiences high bounce rates for their emails, this damages their reputation with ESPs.

But how do you improve bounce rates and, therefore, your reputation? The best way is to have good segmentation practices to ensure the right content goes out to the right people. You should also keep your list clean by regularly evaluating it and removing hard-bounce email addresses as well as inactive subscribers.

Moreover, ensure you send relevant messages that your audience actually wants to receive. Of course, always be mindful of the rest of the triggers on this list to make sure you’re protecting your sender reputation.

5. Misleading email subjects

Even if you’re not trying to do anything malicious, misleading subject lines can trigger email spam filters. For example, an email might claim to promote educational B2B content about internal audit controls. Then, instead, link the user to a landing page to sell them a product.

Always set clear topic sentences as email subject lines. Try to summarize the content and intent of the email. If you’re sending a welcome email for customer retention or promoting, say, a product or sale, make it obvious before the recipient clicks on it.

6. Poorly written and formatted emails

Poor formatting and low-quality writing are other important email spam triggers. Common writing triggers include:

  • Overly vague language lacking personal detail
  • Typos and spelling errors
  • Being too brief

A marketing email can trigger spam filters if it lacks formatting of any kind, or if there are inconsistencies. It’s also suspicious when marketing emails lack branded color schemes, imagery or the correct logo design.
Avoiding these email triggers is simply a matter of emphasizing professional communication standards in email marketing.

7. Poor engagement

Low engagement manifests itself through a lack of interaction with your emails from the recipients—low open rates, click-through rates, and conversion rates, as well as low subscriber count are all indications. 

Consistently low engagement will likely result in your emails being filtered into spam. To combat this, you should strive to deliver good and captivating content tailored to your audience. More specifically, you can:

  • Use segmentation to personalize your emails and craft the most compelling content for each segment.
  • Put together attractive subject lines
  • Make use of solid and clear CTAs

8. Getting blacklisted

Improving your sender reputation, also means you don’t run the risk of being blacklisted. Blacklists are a useful prevention tool, but if you end up on one of these lists, your email marketing is more or less guaranteed to end up in spam folders.

Aim for prevention with email security and compliance training, and don’t send unsolicited marketing emails. You can also use a blacklist checking tool to make sure your sender emails haven’t been compromised.

Maintaining your sender reputation is essential

Email spam triggers aren’t all bad, they ensure that your well crafted messages aren’t drowned out and that users are able to easily see the emails they’re interested in. 

To reap these benefits, you need to keep an eye on these triggers and protect your sender reputation. Don’t worry, though. It’s easy to deliver marketing copy that avoids email spam triggers once you know what they’re looking for.
