Maximising ROI: Unpacking the Cost-Benefit of Email in Business Communication


Business communication is the bedrock of all corporate interactions, facilitating the exchange of information, ideas and plans. It's crucial for product promotion, customer relationship building, internal collaboration and strategic execution.

In this mix, email stands out as a pivotal tool. Introduced during the digital revolution, it's now an integral part of both internal and external business communication. Its capacity for global reach, asynchronous interaction, and professional presentation makes it ideal for the modern, fast-paced business environment.

Email also offers a formal medium for business interactions, providing a detailed record of correspondences. When integrated with other systems, it becomes a powerful platform for increased productivity.

Despite the advent of new technologies, email remains a dominant player in the realm of business communication. This article explores its value, measures of success, and challenges in today's businesses.

Part I: The Power of Email in Business Communication

Global Reach and Accessibility

Emails transcend geographical barriers and time zones, making them an incredibly flexible communication tool. This facilitates dialogue between international colleagues, clients, and partners, helping businesses create a truly global footprint. Furthermore, emails can be accessed across numerous devices, from desktop computers to smartphones, ensuring businesses maintain constant connectivity.


When it comes to cost, emails are significantly more affordable than other traditional forms of communication such as postal mail and SMS. There's no price attached to the distance a message travels, and additional infrastructure isn't required as your mailing list grows. This allows businesses to scale up their email usage without substantial increases in costs.


Emails also provide a chronological record of communication, proving invaluable for reference and legal purposes. In the event of disputes or the need to recall past discussions, the email trail serves as a reliable source of information.

Professionalism and Formality

The nature of email communication lends itself well to the world of business. It offers a professional medium for formal dialogue and documentation, making it apt for serious business interactions.

Integration and Automation

Email's real strength lies in its compatibility with other business systems such as Customer Relationship Management (CRM) tools. It can be seamlessly integrated into these systems to streamline and automate processes. This capacity for automation not only saves time but can significantly increase the overall efficiency of a business.

Cost-Benefit Analysis

Suppose you're operating a business where each successful deal fetches a profit of €1,000, and you're paying €200 per month for your email service. Let's look at this scenario over the course of a year.

If your email communication is generating five new leads every month, and two of these consistently convert into deals, then you're making €2,000 (2 deals x €1,000) each month. Over the course of a year, this translates to €24,000 (€2,000 x 12 months).

Now, let's subtract the annual cost of the email service from this. At €200 per month, your annual email service cost is €2,400 (€200 x 12 months).

Therefore, your net profit for the year, just from the deals closed via email communication, would be €21,600 (€24,000 - €2,400). This gives you a highly impressive return on investment.

If your emails are also leading to increased customer loyalty and repeat business, the potential revenue over time is likely to be much higher. This makes the cost of the email service seem very small compared to the financial benefits your business is reaping. 

Thus, on a monthly basis, you are spending €200 on email services and gaining a net profit of €1,800 (€2,000 - €200). This demonstrates the incredible value of email communication and its significant contribution to achieving your business goals.

Part III: Challenges and Downsides of Email Communication

Information Overload

In today's fast-paced business environment, the sheer volume of emails can lead to 'information overload'. The constant influx of messages often results in important emails being overlooked, delayed responses, and even decreased productivity. Hence, efficient email management strategies are critical to prevent such issues.

Security Concerns

Email communication is not without security risks. Cyber threats like phishing attacks, where fraudulent emails are used to trick recipients into revealing sensitive information, are increasingly common. There are also risks associated with hacking, where unauthorized individuals may gain access to confidential business information. Businesses need to ensure they have robust security measures in place to safeguard against such threats.


One downside of email is the absence of non-verbal cues that we often rely on in face-to-face communication. This lack can lead to misunderstandings and misinterpretations of tone or intent, potentially damaging professional relationships or leading to errors in tasks.

Technological Issues

Technological problems can hamper email communication. Issues such as server downtime can delay the sending or receiving of emails, disrupting business operations. Similarly, overly aggressive spam filters may mistakenly direct legitimate emails to the spam folder, causing important messages to be missed. Ensuring reliable technical support and up-to-date systems are essential to address these potential issues.


Email communication stands as a substantial asset in the realm of business, especially when considering its significant cost-effectiveness. Its remarkable global reach, seamless integration with business systems, and potential for lead generation and deal closures come at a relatively modest cost, making it an attractive investment.

By comparing the financial outlay for email services against the substantial results generated, the value of email becomes abundantly clear. Even a simple cost-benefit analysis, like our example using monthly costs and profits, reveals an impressive return on investment. When extended over a longer term, this profit potential is only magnified, showcasing email's profound contribution to business success.

Furthermore, the potential for customer retention through email communication adds another layer of long-term revenue, making the initial and ongoing costs of the service seem trivial in comparison.

In the grand scheme of business expenditure, the cost of email services is a drop in the ocean. However, the potential benefits and profits it can usher in are more like a tidal wave. So, when it comes to business communication, the cost benefits of email are undeniable. It is not just a means to an end but a significant driver of business success.
