Email clients are software applications that enable users to send, receive, and manage their email. They can be web-based, like Gmail, or desktop applications, such as Microsoft Outlook. These tools help organize emails, manage contacts, and often integrate with calendars and task lists for enhanced productivity. Using an email client can streamline communication by providing features like filtering, tagging, and search capabilities. Many email clients also support multiple accounts, allowing users to manage personal and professional emails in one place. Popular email clients include Thunderbird and Apple Mail, each offering unique functionalities to cater to different user needs.
