Is Email Fatigue Even Real?

People are spending 5 hours a week reading and writing emails and 38.4% of the workforce agrees that they receive between 6 to 10 emails in a day. These two simple facts show we are living in an era of email overload. And it’s taking a toll. common workplace communication tools Source: Emailtooltester It goes without saying that too many emails can hurt productivity, increase work stress, and make it hard for employees to focus on meaningful tasks. Email fatigue is the result of email overload and here’s how they are related. Email overload is when people receive too many emails, more than what they can process. This is due to excessive usage of CC/BCC columns with unnecessary addition of recipients, even if the recipient isn’t related to the sent email. Then, there are too many subscription emails, automated messages, and unnecessary updates that only fill up the inboxes. Last but not least, all emails seem urgent when most aren’t. This leads recipients to;

  • Ignore (knowingly or unknowingly) important emails, as their inboxes are already overflowing.
  • Dreading opening emails as it can amount to doing more work.
  • Reduced engagement due to slow or no response to emails.

Email overload negatively impacts an employee’s performance and the company’s overall health.

Negative Effects of Email Overload: Detailed Overview

Email overload is just another annoyance people experience at their workplace that will go away in some time. Too many emails can have a detrimental effect on employees with 33% of them agreeing that email overload is one of the factors for them leaving their job according to a Forbes study.

Lost Productivity and Reduced Efficiency

Too many emails mean employees will spend too much time reading and writing emails, which leaves them with less time to focus on more important tasks. Yes, communication is important, but spending a good chunk of time on just email engagement isn’t worth it. On top of this, some organizations ask employees to reply to emails almost immediately, which is not a practical solution. Replying to emails constantly affects the employee’s workflow, distracting them to lose focus from the ongoing task. A loss in productivity is also an indicator of decision fatigue. Too many emails lead to slower decision-making because the employees cannot give enough time to each email, hence making hasty decisions affecting work efficiency.

Increase in Work Stress

An overloaded email inbox will slowly start eating into the employee’s comfort and peace of mind. Soon, checking every email will feel like an insurmountable challenge. So, failure to manage the inbox initially can easily overwhelm the employees, especially when the thought strikes that they might be missing important messages. The stress increases further when an employee’s manager begins to notice the employee’s failure to respond. So, in addition to the employees feeling burned out, their productivity will start decreasing, and they will disengage, ultimately leading to absenteeism and employee churn. If that’s not all, employees with overflowing email inboxes feel obligated to check messages after work hours leading to exhaustion and frustration.

Builds an Urgent Need to Multitask

While multitasking is expected from people, it shouldn’t become a habit or ingrained into the work culture. Over the years, multitasking can turn inefficient and eventually have the opposite effect, which is to bring down productivity levels. As we have said before, frequent pings signaling a new email is received distracts the individual and forces anyone to switch from task to task, app to app, and workflow to workflow.

Missing Collaboration Opportunities

With important and general emails kept in the same inbox, it’s easier for the critical messages to get mixed up or even lost. As the important emails move deeper into the inbox, they become invisible. Employees with overflowing inboxes will inevitably miss these emails, and failure to respond to critical and collaboration emails on time can mean missed opportunities.

Employee’s Professional Image Takes a Dent

An employee’s inability to reply to emails on time not only leads to missed opportunities but also makes them look unprofessional. Among many reasons for not engaging with critical emails is that the employee failed at email management, was disorganized, and was unreliable. Ultimately, it blows a big dent in the employee’s professional reputation.

Delayed Decision-Making (Employer’s Perspective)

Poor email management on the employee’s and employer’s end ultimately leads to delayed decision-making. This happens as important discussions get buried in long email chains, and critical messages from the employees fail to arrive, leading to delayed decision-making. Another reason why email overload can delay decisions is that employees may start to ignore emails altogether, leading to communication breakdowns.

Factors Contributing to Email Overload

If you are trying to find an answer to how many emails are too many for your workforce to become a burden, there’s no definite answer. Everything depends on the employee’s workload, responsibilities, and accessibility. However, we have determined some factors that have led to email fatigue and why regularly receiving emails can negatively impact an employee's performance.

  • Lack of Empowerment: When employees feel a lack of empowerment, every email will feel like a burden. In other words, when employees don’t have decision-making capability and have to get permission for everything they do, it’s natural for them to use emails to seek approval.

As a result, this creates an endless cycle of email communication, further leading to cluttering the inbox with “too many” emails. This shows companies still need to create an empowerment culture and implement understandable norms for corporate communication.

  • Poor Email Etiquette and Overcommunication: Some employees have the habit of sending excessive emails, which leads to overuse of CC/BCC, long email threads, and vague subject lines. This forces recipients to sift through seemingly endless, irrelevant messages.

Such behavior is mostly seen in companies where overcommunication is a norm, and employees feel compelled to respond to everything.

  • Lack of Clear Communication Channels: To achieve communication efficiency, companies need to build effective communication channels. When these companies don’t have defined channels of communication, everything ultimately ends up in emails.

This is when there are no Slack channels for quick updates, task management tools for projects, etc., resulting in an overflow of messages that can be handled elsewhere.

  • Culture of Instant Responsiveness: When companies require employees to reply to emails and messages instantly, it forces them to check their inboxes frequently.

Naturally, this is going to disrupt their work, but the urge to reply quickly can cause employees to send rushed and unclear emails. This sort of behavior creates a vicious cycle of even more follow-ups, hence more emails.

  • Lack of Training on Email Best Practices: Organizations must train their employees or at least share a document highlighting the rules and formats for email management. Not knowing the rules or best practices, it's common for employees to send long and unclear messages.

Solutions to Combat Email Overload

Remote work has contributed to email overload as there are fewer face-to-face conversations. Decisions that can be taken easily with a single meeting now are taken with multiple online meetings or long email threads. Here’s how to deal with it:

1. Set Boundaries and Learn to Prioritize

First of all, every employee shall set some clear boundaries about checking emails. Access emails at a designated time, avoid unnecessary CC/BCCs, and use concise and clear subject lines. Build a habit of checking emails at a specific time and set a time limit here as well. For instance, set aside 30 minutes to check emails and studies have proven that those who check emails just a few times at designated intervals are less stressed than those who check emails frequently.

2. Develop Clear Communication Rules

Communication cannot be clear and smooth if it’s not carried out with clear rules. Having some communication rules is even more important for organizations working in remote settings. No organization uses only email for communication.

  • With different communication channels, it should be clear which sort of communication shall take place through which channel.
  • Limit CC/BCC usage by establishing strict rules that employees shall only add recipients to CC or BCC when needed.
  • Train employees to use clear email subject lines; bullet points in email body content, and action-oriented messaging to reduce unnecessary back and forth.

3. Clear out the Inbox Frequently and Daily

A full inbox is painful for any employee. Every employee shall have a plan to clear out their inbox, get rid of unwanted emails, and avoid creating a backlog. There’s a simple formula to clear out the inbox: the 4Ds;

For the tasks you have deferred, ensure to check them before signing off so that you don’t have a chunk of emails to check first thing in the morning.

4. Create Inbox Filters

Every email provider has a built-in filter and label system. Use these to categorize your emails, ensuring every email lands in the right category, and it contributes to easy management. Email providers like Gmail and Outlook set rules that will send every email either into a color-coded box, boxes based on priority, sender, etc. This helps an employee scan the different inboxes, open the emails they need, and delete the rest before they become a pile of waste.

5. Minimize Dependency on Emails

There’s no need to do everything via email. Use emails to assign tasks, but use project management tools like Trello, Asana, Notion, etc., where each employee has a designated task board, and the managers have a composite view of every task and deliverable in one place. In addition to this, create shared knowledge bases and upload them on shared drives. This ensures there will be no unnecessary emails circling around the company where employees are asking about even the smallest details from their seniors. Also, adopting AI voice solutions can further help improve communication by reducing the need for extended email exchanges. Using AI-powered voice tools, employees can easily convert text to speech and use voice-based collaboration to make internal communications faster.

6. Change Meeting Culture

What can be decided in a 10 to 15-minute meeting could take multiple emails sent and received among multiple recipients. So instead of this continuous back-and-forth, not to mention the time wasted on waiting for replies, build a culture where employees get into a short meeting to discuss things over and make a decision.

7. Give Training on Email Best Practices

Hold email training workshops to teach employees how to write clear emails, use email filters, set rules, and manage their inboxes efficiently. Moreover, help them build habits of checking emails at fixed intervals while encouraging their habit of responding to emails immediately unless it’s absolutely necessary.
