How does an email A/B testing campaign work?
- A/B testing in email marketing or split testing, is a way of reaching a conclusion of which of two email campaign variations ensures more opens and clicks. The whole process of A/B email testing involves:
- Setting up of two variations of the campaign.
- Variations can be done on the email, ranging from subject lines, email preheaders to the design and CTA buttons.
- Sending the variations to a segment of your contacts. Half of the test segment receives Version A, other half gets Version B.
- The winning version is selected by comparing open and click-through rates. And it is then sent to the remaining subscribers.
Benefits of email A/B testing
If you aren’t convinced yet, here are some reasons how Email Split Testing will help your brand indefinitely:

“ One small change can make a huge difference!”

What should you experiment on?

- Subject line

Stealing your audiences’ attention from their highly cluttered inbox is the most difficult but also highly effective first move-in email marketing. Make your subject line catchy, humorous, short, simple and beneficial depending on your audience.
Different parameters of the subject line you can A/B Test are:
- Word order

Experimenting your visuals!
Adding engaging visuals to your emails lets you grab the attention of the readers. Use of visuals depends on your Industry. For example, in the fashion industry, the trend moves towards glamorous and flashy visuals. But it is shifted more towards more formal and plain ones in the financial sector.
- Images are attractive. It’s a great way to engage the audience. But when you have to send an important email, images act like a villain. It drives away attention from the content of your email. And it’s always better to not go beyond more than two images.I would say, adding or not adding images depends on your email type and content. It may work for some emails but not others. Explore whether or not they are working by A/B testing emails.
- The font and colour of your text is another great thing to run an A/B test on. Some fonts have more impact on readers and generate a higher engagement rate. Legibility of the text is affected by its font.
If it is very small and hard to read, it turns the readers away. .Even slight changes in the visualization of texts might give you larger variations in conversions.
Are you wondering if you should include visuals(i.e images and colourful designs) in your email campaigns? And what kind of visuals will work best? Answers to these questions will be given by A/B testing in email marketing.
Length of your email
With the approach of smart screen Mobile phones, email design trends are looking at shorter emails. The suitable length of the email will depend on:
- The email content
- Purpose of the email
- Complexity of your product and
- The audience.
If you want to send an email that convinces the recipient by a detailed explanation of the benefits and features of your product, then you should go for a detailed longer email format. But no one wants to read long descriptive paragraphs in a Christmas Day email.
Consider email A/B testing to figure out if you should sort to short or long-form emails, the next time you are launching a new product or while making announcements.
Tone of your email
The tone you use plays a significant role in engaging your reader’s mind. Keeping your messages simple, understandable and using a positive tone in your email, motivates recipients to click-through and keep in touch with your market.
Read out your email, and listen to how it sounds. Keep your tone positive, neutral, friendly and human.
Tone of the email varies across industries and audiences. You can use a sweet and humorous tone in your emails. But not everyone has time for cheesy lines or lures.
Perform an A/B test to find how one tone can outperform another tone. And bring in more conversions and ROI.
Calls to action
Calls to action gives the clear picture of what to do next to your audience. CTAs can be hypertext, images or buttons. The design of your CTA button has major effects on the attractiveness of your email.
- Placement of your CTA button – Figure out where you need to place your CTA button with A/B email testing. In the beginning of the email? To the sides or at the bottom?
- While you are doing an email split test, try to compare different colours and formats of CTA buttons. You will witness major differences in the outcomes.
- CTA content is also equally important as the design and format. Make it short and understandable.
Send date and time

How to analyse A/B email testing results?
Advanced email marketing software like Mailercloud, compares both the A and B campaigns automatically based on multitude of matrices like opens, clicks, unsubscribes, bounces, spam traps, conversion, abuses and complaints and informs you about the winning campaign.
But if you are comparing the results manually, you don’t need to compare all of them. But most importantly set your focus on:
- Open rates: Number of emails that were opened by the recipient.
- Click-through rate: Shows you everyone who opened the email and clicked a link you provided that led them to your page.
- Unsubscribes: This is an important metric to monitor because it shows how many people do not want to get in touch again with you.
- Bounce rates: The percentage of your subscribers that didn’t receive your message because their mail servers returned them.
A/B testing mistakes to avoid
The concept of A/B testing is very simple. However, we tend to make mistakes, which would rapidly decline all our conversion rates. And all the hard work behind A/B testing would be futile.

- Say no to Split tests on holidays or important days: Holidays are the times when your audience is frequently checking through their emails, for any upcoming offers or informative newsletters. This is not the time to experiment. Also avoid:
- Sales day and
