Best email clients

Email is an essential part of our lives: personal and work-related messages, newsletters we’ve subscribed to, and receipts all pass through it. There are many email clients with different features and capabilities, from enhanced security to user-friendly interfaces and customizable settings. How to choose the best email app? In this article, we’ll explore the best email clients for Windows and other platforms, examining their features, advantages, and disadvantages so you can choose the one that meets all your needs.

What is an email client?

An email client is an application that allows you to receive and send messages, create folders and labels. Good email clients offer many useful features: contact management, calendar integration, and the ability to set up multiple email accounts on one platform. For example, Microsoft Outlook, Apple Mail, and Mozilla Thunderbird are some of the most popular email clients.

There are three types of email clients: desktop, mobile, and web applications. Desktop applications often have advanced features, backup capabilities, and additional security measures.

Web applications are accessed through a browser and reside on a remote server. They are usually free, easy to use, and only work when you have an Internet connection. However, they often have fewer features than desktop clients.

Mobile applications combine the functionality of web and desktop applications with compactness and ease of use. Typically, accessing your mailbox straight from your phone comes with some drawbacks, and some features may be missing or limited in mobile email clients.

Why do you need an email client?

Email clients help you send, receive, organize, and manage your emails. Many of them include spam and virus protection, encryption capabilities, blocking unwanted emails, and other features to defend against unwanted content.

In addition, email clients allow you to work with multiple mailboxes at the same time. This feature is useful for people who have multiple email addresses. All of your emails will be in one place, so you can respond quickly to messages and never miss important information. Email clients can also integrate with other tools like calendars and task managers. This allows you to easily manage your work schedule and tasks from your mailbox without wasting time switching between applications. These tools also help to prevent potential errors and duplication of information.

How to choose your best email client

Choosing the best email app might be difficult when there are so many options. Making a decision based on these criteria can simplify the process:

  • Compatibility: Make sure the client you choose is compatible with all of your devices (PCs, smartphones, tablets) and your operating system (Windows, macOS, Android, iOS, Linux)

  • Features and capabilities: Email clients vary significantly in their features, from basic management to advanced automation tools. Look for an email service that is easy and convenient to use for sending, receiving, and searching for emails. Some people like the ability to add multiple accounts, integrate calendars, and schedule email delivery

  • Security: Since emails may contain confidential information, security and privacy are crucial when choosing an email client. Look for email clients that offer end-to-end encryption, two-factor authentication, and spam and virus protection. The best email app should also be compliant with privacy regulations such as GDPR and CCPA

  • Integration: Email exchange is often part of a wider workflow, so your email client should integrate with other tools, third-party extensions, and plug-ins to enhance functionality. Integration with popular third-party services such as Microsoft Office 365, Google Workspace, and Dropbox makes your workflow more efficient and opens up more opportunities for collaboration

  • Offline access: Make sure the client you choose allows you to work with emails without an Internet connection, with automatic data synchronization when you reconnect

  • Support: Customer support is important when choosing the best email client. Look for an email client that comes with detailed documentation, video tutorials, and a knowledge base. It should also have a responsive support team that can help you with any problems you may have

  • Cost: Decide if you’re satisfied with a basic free email client or if you need additional features only available in a paid version. Compare the prices of different email clients and choose the option that fits your budget

  • User interface: A good user interface should be simple and intuitive. It should also be visually appealing to you, with customizable themes and color schemes. The interface should allow you to easily search, filter, and organize email into folders
