Choosing the Best Email Client Software

The list of the best email client software

Many of us have multiple email accounts that we regularly check for new messages. Managing them can become time-consuming, especially if you have to log into each of them separately. Using an email client can streamline this process by allowing you to access all of your accounts in one place, without repeatedly entering login information. 

This article will discuss what an email client is, what to consider when choosing one, and provide examples of some popular options.

What is an email client?

A mail client is software that allows you to work with different mailboxes using one platform. The main advantage it provides is time saving. After all, you no longer need to enter each mailbox individually. 

The client helps to:

  • Receive, store, and send emails
  • Sort messages by their importance and type
  • Edit emails with options for font style, color, and size or using templates with preset layouts
  • Set up automatic sending
  • Export and import emails into other programs

Many email clients have an extensive list of features either thanks to built-in functions or compatibility with external programs. For instance, some of the advanced capabilities include email delegation, setting up auto-responders for when you are out of office, and organizing emails into folders or labels.

In addition, an email client allows you to store your email data on your computer and in the cloud. Whereas web-based email services store everything on the server only. This is why email clients are better for business: it’s easier for you to access your work emails and they are better protected.

How to choose the best email client software

Choosing an email client can be tricky because everyone has different needs and preferences. However, we compiled a list of a few key characteristics to look out for:

Supported platforms

Supported platforms and device compatibility are critical factors in choosing an email client. Can the software be used on multiple operating systems (for instance, on Linux and Mac), or just one? Make sure to check if the software can run on your device before purchasing or downloading. Check if it has a mobile version for on-the-go access.

Normally, email clients have no issue working with widely used providers such as Google or Yahoo. Still, if you’re using a less known service, it’s best to confirm that the client can support it ahead of time.

Available features

Get to know the features of your client of choice and how it integrates with other programs. There are some email clients that offer more than others in terms of features and connections. Some might be really useful for work with such features like task management, calendar integration, and note taking. Others might be more suitable for personal use with options like customizable themes and automatic email sorting into folders. 

Design and ease of use

Feeling comfortable with your email client is important. What’s convenient for you is mostly a matter of preference. Some people like simpler layouts while others might prefer more advanced features. Take some time to explore and test out the interface before committing. Consider if it’s user-friendly and how easy it is to navigate through the various options and settings. Also, think about if you find the interface aesthetically pleasing and customizable to your preferences.

Price

Make sure that the pricing works for your budget and needs. Some email clients may have a one-time payment option, while others offer a monthly or yearly subscription. Some might even have a free version with the basic functions: sorting, sending, mail search. Compare the options and pick the best fit for you.
