What is so important about A_B testing_

How does the A/B Testing email works?

Firstly, you set two different variants of your email campaign. Then you prepare two different address lists where your emails will go. And then you simply sit back and analyze the results popping in from each variant of your marketing A/B. The winning variant with the best results assessed from the split testing email marketing will then be sent to the rest of the subscribers directly. Well, A/B testing in email marketing requires applying an extra bit of text in the email body you prepare along with an extra subject line.

How to conduct A/B testing of Email Newsletters?

You can use certain messaging platforms to execute your A/B testing for free email newsletter testing. Once you set your a/b testing platform, set different parameters like for instance two different subject lines, two different images, different sets of content, etc. You just have to create two different versions of the email that can represent two different variants of the a/b testing newsletter campaign.

You can name the two variants as Variant A and Variant B, or any other name that you wish. Then set the measures and conditions on the basis of which you are going to rate among the variants. For instance, open rates, CTRs, deliverability rates, etc.

Now, take 40%-50% of your customer or subscriber base and divide them equally between the two variants. Begin the test and after its completion, compare and analyze the results and then send a newsletter that has the highest of metric measurements for the left 60%-50% of subscribers on whom you have not tested.

How long to conduct A/B testing?

You can set your campaign monitor a/b testing schedules as per the previous campaign schedules you have had. How much time did it take for your email newsletters to get opened? If your email campaign a/b testing occurred the highest within the first 24 hours and for the rest of the days, it gets an average open rate of close to 4%-5%, then it is better to limit your free email newsletter testing up to the first 24 hours.

Extending your a/b testing newsletter for extra hours or days won’t make much sense. Though, if you have a huge email list and it is impossible for you to gather results within a few days, then you can extend the test depending on the effectiveness of the campaign.

What to test in the Email?

1. Sender name and Sender address

The sender’s name is one of the primary things which the recipient notices. Per day a recipient receives over 150 emails on average. So, for you, it is extremely important to grab their attention in the first go. 64% of people open the mail based upon the ‘from’ title. You need to understand that you don’t just have to compete with your direct competitors but also the personal mails received by a recipient.

So, you need to give special attention to your “from” address and name and then test it. You can simply examine it by adding the names of chief employees working at your company or replacing them with the company’s name. Adding a human name in the “from” name can create an impact on those recipients who haven’t engaged with you in recent times.

2. Subject line and Preheader texts

Email testing is incomplete without subject line and preheader text tests. Mainly you should pay attention to the formulation and length of a subject line while curating it. The subject line should be usually short-lengthened, but some long yet innovative subject line length is also a matter of attraction for many recipients.   

The preheader texts are also very important. You need to curate a unique preheader text after the subject line so that the recipient instantly opens the mail. You can also personalize the subject line with your first name or the company’s name. Test one batch by personalizing with your first name or company’s name and the other batch of emails without it.

You can also test whether the lowercase subject line works for you or not. You can just test it out by adding the subject line on some of the email batches with only the first letter of the sentence capital like All your problems are fixed, (First name). And on other batches like All Your Problems Are Fixed, (First name) with each word of the sentence starting with a capital letter.

Many companies have also observed higher email read rates due to the usage of emojis instead of words. You can test it out if your target audience falls under a certain age group that gets attracted by emojis.

You can also try including questions in your subject line. This creates an instant conversation between you and the recipients. It also tends to enhance the engagement of the recipients with your business. Hence examine all the above tests, observe which of the email types has the highest read rates, and choose the pattern accordingly.

3. Font of Heading and Subheading

Choosing a font for headings and subheadings can be compared to making a fashion statement. And you know it well that the fashion statements speak a lot about your personality and style. You need to test if certain fonts work better for you than the rest. You can use distinct fonts to highlight some of your important areas in headings and subheadings.

In the same way, you also need to choose a perfect font size for your subheadings and headings. Ideally, there should be three different font sizes. One for the heading, another for the subheading, and the last one for the description of the product. You can always experiment with the font sizes to determine which font size is capable of capturing the attention of the recipient.

Along with the font sizes, font weights are also important. The font weights will highlight some parts more and a tint of uniqueness will be added to that text. You can adjust the weight and sizes of the font to observe if there is any effect on the overall results. Make sure the fonts that you choose are not intricate and can be visually well perceived.

4. The location and number of Calls to action

The conversion rates can affect the location where you display the campaign on your website. Test if there is any difference if you display it on a peculiar page, on each page of your website, or via distinct URL paths.

At the end of the day, there are some kinds of goals that you need to meet while email marketing. This means that everything you send to your subscribers should benefit you in one or another way. Hence here are some Calls to Action (CTAs) that can help to boost your sales and give you the best results.

You need to choose the appropriate color. Humans respond to different colors in different ways. So you need to examine which color creates magic for you and your recipients.

You can also examine the placement of your campaign. This will help you understand the clicking pattern of your recipients and accordingly, you can set your campaign placement.

Testing the shape of your buttons will also aid your sales. The shapes of these buttons should urge the recipient to click them right away. You must include all these CTAs and observe what works best for you!

5. Usage of the list

When you compare two emails, one with the text arranged in a list format and the other with a solid text you can instantly spot the difference. The list makes it easy to retain and the information is fascinating to read. Nevertheless, the preference differs for each recipient hence test the usage of lists and see if that favors you.

6. Link Order

• In email marketing, you need to build deep connections with subscribers. In such cases, you can offer resources but only if the subscribers are ready to tell you what they want.

• While testing, send an email with solid text about the resources and add the actual link in this text. In another email, you can add a source/ button saying something like “click here” to download.

• You can add content to the link directly or simply put in a step on your page to link it to an opt-in page. Link any 2 links to the same resource in your email or incorporate any two CTAs. See how many subscribers are into it and choose the appropriate option.

• You can avoid adding social links in your email as it is said that it may distract the consumers from the offer-related matter.

• You can also add contact links and give your recipients a chance to schedule a call with you according to them. You can just set up your available timings and link them to your calendar. Gather all the data from these tests and redefine your highest success rates.

7. The tone of appeal

In business, you must capture people’s hearts through the tone of your emails. For some people, an informal tone in the email can be very appealing. Others may be convinced with a formal tone. Try out what your target audience connects the most by A/B testing.

10. Limitation of time

Urgency grabs the most attention. For example, people tend to click faster on “2 hours left” or on “only 1 day remaining”. Conduct an A/B test to observe if you should include a campaign that displays on the placement instantly or the one which takes time. Test if the urgent ones are better options than normal.

11. Price variations

Test what type of price formulation retains the interests of the subscribers. Like, is “20% off” working effectively than “Save 200 bucks”.

12. Color of the letter 

As mentioned earlier different colors have a different impact on one’s mind. You must test the best color which suits your article the most. According to a survey, it is stated that the yellow color grabs the attention.

The red color is responsible for stating urgency. Blue is one of the best colors to provoke a sense of trust amongst the consumers. Black is stated as the symbol of luxury or power.
