by Arthur Zuckerman

The popularity of email marketing has skyrocketed since its inception. One reason for this is the fact that it has an ROI of up to 4400% — this is a $44 return on every $1 invested. Of course, this only happens when email marketing is done the proper way. However, we’re not going to delve much on how to do it in this article. But, we’ll do our best to provide a cursory view of how to do it properly using case examples.

To wit, email marketing has many uses in many cases. For instance, it is used for sales, content marketing, SEO, and even CRM. Thus, when you are scouting for an email marketing software, you need to find a flexible one that can cater to these types of needs. Also, always remember that this tool is not just for external communications. You can also use this to blast memos, announcements, and even HR-level promotions like for a company event using this tool.

But, what are the general features of email marketing software? What is the importance of email marketing and the benefits of using one? In this article, we’ll discuss these and other essential details, such as different email marketing software types and even their potential issues. Furthermore, the article also touches on the latest trends in email marketing software usage and adoption.

What is Email Marketing Software?

Email marketing tools help users communicate and conduct transactions easily with email as the main channel. However, expert users integrate email as a channel to other digital touchpoints like their websites, social media accounts, blogs, help pages, and others. This ensures a seamless customer experience that is vital to generating leads, sales, and retaining a loyal customer base.

Users mainly enjoy how it makes this simple. This is thanks to tools and modules in top email marketing platforms that allow for segmentation, bulk email sending, and personalization. Moreover, there are many automation features that are beneficial, as well. With them, you don’t do everything manually. You can just let the program send, receive, categorize, and reply to you, among many other things.

Moreover, good email marketing platforms include modules for reporting and metrics. In fact, these are prerequisites. These tools help you split-test campaigns and get an idea of your ROI. If you do things manually through spreadsheets, these are very tedious to do. Plus, you could run into many problems, such as inaccurate inputs.

Furthermore, email marketing solutions provide you with real-time dashboards as well. In this way, you won’t lag in both accuracy and timeliness for reports. Now, you can rest assured that your data is pristine and easily optimize previous tactics and strategies.

Email Marketing Software Types

There are different types of email marketing tools. Some are quite general and very customizable to your needs. Others are very specialized. Also, if you want to be strict about all the types of solutions, there would be too many to list. So, we’ll settle for general categorical types.

  • Autoresponders. Email marketing solutions usually include an autoresponder function. In its most basic sense and usage, this function helps users cut time and reduce effort by automatically replying to general emails. However, today, autoresponders are quite advanced. You can set them to notify you via SMS and social media. Also, you can set them to send canned yet personalized responses. For example, if someone makes an inquiry, you can send them a help desk article automatically. Also, the software automatically personalizes the email by adding the recipient’s name. With these features handy, you can use autoresponders to generate leads.
  • Newsletters. Some solutions specialize in helping you create beautiful, highly-visual newsletters. The top ones even let you create interactive emails. Often, newsletter creator and manager solutions are used for product promotions, rolling out of sales, and content marketing. Thus, these can help you drive traffic for SEO, generate sales leads, and increase reach and brand loyalty.
  • Sales and Transactions. Other programs are mainly used for sales and other opt-ins. For instance, you can create interactive emails that let users purchase from your store directly from your email newsletter. This reduces the time and effort on your customers’ part to go to another link and website. Typical uses include email receipts, password resets, opt-in confirmation, payment reminders, and payment confirmation.

Key Features of Email Marketing Software

In the previous section, we’ve listed popular platforms in use today. They may have differences in terms of their features. However, they share common ones that make them go-to solutions. In this section, we’ll give you a general look at what the requisite features are for a good email marketing platform. Here they are.

  • Workflow Automation and Autoresponders
  • Newsletter and Email Builder
  • A/B Testing Tool
  • Social Media and CRM Integrations
  • Analytics and Reporting
  • CAN-SPAM Rules

Workflow Automation and Autoresponders

No good email marketing software exists without an autoresponder. This tool allows you to send replies, canned messages, and personalized email campaigns. This saves you time and effort from doing these things manually. Also, this feature comes in tandem with a workflow automation module. What this does is automatically act on your behalf using triggers and preset rules. Of course, you have to customize these yourself to tell the program what to do. For instance, when an email comes in that is part of a conversation tagged as sales, the program can then flag it to get your attention.

Newsletter and Email Builder

Email builders allow you to personalize canned messages. This is an important feature when sending out mass emails for promotions. Email recipients seem to be more responsive to personalized emails. But it is hard and tedious to insert personalized salutations on your own. Through rule-based computation, email builders do all of this for you. Thanks to what they call merge tags, which allow you to replace variables in your copy with personalized elements.

Moreover, you should choose a platform that has an easy-to-use drag-and-drop email and newsletter editor built-in. In this way, you won’t have to know how to code to create beautiful and engaging emails and newsletters for your audience. Moreover, its also best to choose platforms with ecommerce integrations if you plan to sell directly through email.

A/B Testing Tool

Not sure what text or graphic works for a particular segment? Do A/B testing. Just like its name, it allows you to send out an A copy or B copy of an email for a campaign to test out which ones work. This is important as it helps you finetune and optimize your messages. Also, it enables you to find your writing voice for particular segments. Copywriting isn’t an exact science. However, measuring its performance can be pretty scientific. And, with this tool, you can approach your email marketing more scientifically. Albeit still involves guesswork.

Social Media and CRM Integrations

Email marketing does not exist in a vacuum. Experts use it to generate leads and traffic to other touchpoints where they can make a sale or continue to engage prospects. And, not all people want to communicate via email. This is especially true with B2C consumers. Thus, it is best to have your email marketing platform integrate with CRM and social media tools when you have B2C customers. But, keep in mind that the B2B market is slowly turning into a B2C one. So, if your email marketing software doesn’t have a CRM module in place, you better have it integrated with a standalone CRM system.

Analytics and Reporting

Again, email marketing is not an exact science. However, just like many sciences studying dynamic and complex phenomena, people can exact patterns that hold in the chaos. For business operations, this is done through the help of analytics and reporting tools. However, it is already hard to do even when you are not handy with digital spreadsheet tools. Thus, if you want to measure the success of your campaigns and have a chance at optimizing your efforts, its best to have a platform with these features. And, the top ones do.


There are laws prohibiting spamming. This is especially true for the US and EU. CAN-SPAM is a module that analyzes your email for the chances of it getting blocked by spam filters, HTML structure, or broken links. So, before you shoot an essentially dead email to the cloud, you get notified before you do.

The Benefits of Using Email Marketing Software

A set of preferred benefits are necessarily just preferred outcomes. And, its different strokes for different folks. But, there are general benefits to using email marketing software, and here they are:

  • Save time and money
  • Send more emails
  • Reply to more emails with “canned” personalized touch.
  • Have all your contacts handy
  • Generate reports and insights automatically.
  • Layout emails and newsletters with ease.
  • Quantify email campaign success and performance.
  • Identify areas to improve on.
  • Quickly segment audience.
  • Buying forces you to maximize the use of your investment.
  • Never miss an email again

There is not much doubt that when used the right way, email marketing tools can give you good value for your investment. Think about this in this way. If you already have a successful email marketing process without the tool, then when you adopt it, you get to decrease your manhours. This counts as savings in terms of time, effort, and money. Also, when you have a formula that works for you already, you get the chance to increase its range. Thus, assuming all things are equal, you get more bang for your buck right from the start.

How Do Email Marketing Software Work?

In the previous sections, we’ve mentioned how email marketing tools work. However, we’d like to dissect it further and state them more clearly and in sequence for you to get a better understanding of how to use them. Firstly, there is something that most, if not all, of these software solutions lack that is very important to email marketing. This is a database of emails for cold email campaigns. This is where your ingenuity comes in.

You mainly deal with this in two ways. One, you create landing pages to opt-in to your newsletter subscription and redirect prospects from your other touchpoints there–both online and offline. Second, you scrape emails from sites, social media, or subscribe to a prospect database service. Of course, you can mix these all up and see what works. Now, that you have your contacts, you’d be able to have a process that goes something like this:

  1. Create landing pages (opt-in) for the email newsletter campaigns and have them on various touchpoints.
  2. Segmentize your contact database.
  3. Develop content for each segment.
  4. Do test emails using A/B or split testing.
  5. Optimize your emails according to results.
  6. Set autoresponder rules and automation according to results.
  7. Launch your campaign.
  8. Measure campaign as you go, correct your course if need be.
  9. Be mindful of your workflow and automation rules (correct whenever need be).
  10. At the end of the campaign, analyze performance, and gather insights for the next one.
  11. Rinse and repeat.

Email marketing software works through workflows, rules, and stages that you set. It is a program that will nudge you to do things correctly and accurately. Thus, it is you that works with it, and there are many best practices that we can’t get into here. You should do your research from time to time to keep yourself updated with these.

Potential Issues with Email Marketing Software Usage

As discussed, there is the human factor when it comes to adopting and using email marketing systems. This is really where most of the problem lies. Of course, there are software issues as well, especially when you adopt not-so-well-designed platforms. But, they rarely stay long in the market. Consumers are more discriminating these days. Common people issues are as follows:

Lack of security awareness

Firstly, many people that do email marketing are not aware of security issues. This pertains to the security of their data and how they encroach on the security and privacy of others. This includes the sending of spammy emails that, when you do it to the “right” person, many will retaliate. Some would only speak out against your company’s practice. Others that can hack your system and have the time to do it may do it. So, it is best to have additional security measures on your end as you have private information stored. This information is delicate and valuable. Also, it is not only you that own it. It is owned by your customers too. A breach will be bad for business.

Underutilization of tools

Secondly, many firms underutilize their email marketing software tools. This is because they lack the type of onboarding necessary to get everyone in on the project up to speed with the features. Thus, they use their tools below their real potential. One way to deal with this issue and, I argue, the best approach is to tackle this head-on. How? By allotting time and effort to get to know the tools in and out. Think of it as an investment. Spend time now and gain all the benefits in the future instead of going somewhat blind through campaigns and never learning much.

Not integrated with other systems and workflows

Thirdly, email marketing software usually integrates with other business systems. Other users find it tedious to integrate them with other systems, though. This may work for some. However, again, this does bring the best out of your system.

Furthermore, others don’t have their email campaigns integrated with their actual workflow. It exists in a silo done by one or two people separate from everything else the company is doing. Thus, you wouldn’t get to see the ROI or the liability of the campaigns fully. The first step into a better view of your processes is to acknowledge that they work together for you.

Factors to Consider When Buying a Software

Buying software is not a simple task. This is especially when you subscribe to annual plans and invest some time into learning how to use it and adapt it to fit your operation. You must do it with due diligence, care, and critical thinking. So, here are some questions that you should consider when purchasing a subscription plan.

  • How many people will get to use it?
  • Are there any cheaper alternatives but with the same capabilities?
  • Is the user interface intuitive and simple enough for a teen to operate it?
  • Which pricing plan and package fits my needs?
  • Does the software provider have excellent customer service?
  • Do they have a self-service database, and how good is it?
  • How secure is my information on the platform?
  • What do other people say about the software?
  • How can I measure the ROI on my subscription?

These are just some things that you should consider. Other factors include aesthetics and your organizational culture. Why? Well, if you think about it, nobody likes to use an awkward-looking tool everyday. And, if your corporate culture is resistant to change, you could bet that your tool would not be used well.

Latest Email Marketing Trends

Marketers say that the main goals for email marketing are retaining customer base (29%), increasing engagement (22%), sales (17%), building brand awareness (13%), delivering relevant content (11%), and driving more website traffic (10%).  This shows that it is being used in key business processes. It is not just an extra service that you will do better if you do without. Thus, it is good to ponder how you can leverage it successfully, just like top users.

This may be true. However, many operations have fewer than five people working on email campaigns. Also, they don’t have in-house abilities for HTML, design, and development. About 82% of the respondents rely on templates. What this means is that there is so much to be improved when it comes to email marketing across the industry. These include the expertise of the people making them.

Lastly, relatively recent regulations may progress into stricter ones. Data is today’s prized possession. There is a public debate on whether who owns it. Is it the public? Is it the company? Or is it the actual person? This is likely going to lead to tighter regulations. So, it is best to follow the current rules and have a platform that is secure and ethical.
