What Is An Email Client?

An email client or email reader is a software program that you can use to manage one or more of your email accounts. Sometimes, it is also known as a mail user agent or message user agent.

Its major purpose involves exchanging and managing emails for one or more accounts. Several email clients offer additional features, such as spell check and auto-replies, that further enhance user experience. For these extras and multiple account support, people often prefer email clients over web-based email.

What To Look For In Email Clients?

Choosing the best email client isn’t as tough a job as it might seem when overwhelmed with options. One of the main reasons people resort to using an email client application is the fact that most of them sync multiple different email addresses at the same time. So, naturally, it would benefit you from choosing an email client that is enough for all your email addresses.

Other factors of deciding your pick are subjective and depend on your unique needs. For those who must avoid a typo at all costs, a client that provides a spell check feature is of big importance. On the other hand, someone else might find features, such as auto-replies and language translation, more crucial to their usage.

So basically, after you have filtered out the email clients that support all your important accounts, you would have to choose among them based on the features you find useful.


While each email app mentioned above has its own pros and cons, Mailspring is our go-to mail client. The support for up to 4 accounts at once it offers in the free version is a crucial determinant for our pick. On top of that, its impressive range of features and add-ons are a big bonus.

By the way, if you are someone who ranks privacy over anything when it comes to email, you might want to choose your email service provider thoughtfully. Here is a list of the best free email services we made earlier.
