Gmail

Google's Gmail has more than a billion users worldwide, making it a powerful free email service. With its 15GB data allowance and advanced anti-spam and phishing protection, it is no surprise that Gmail is popular. It also integrates smoothly with other Google productivity tools like Chat, Meet, Calendar, Docs, and Drive, as well as email clients such as Outlook, Apple Mail, and Thunderbird. Setting up Gmail on desktops and mobiles is straightforward, and the interface is clean and collapsible to ensure it doesn't interfere with your work. However, some features may not be appealing to everyone, such as the Smart Compose feature that makes suggestions while typing.

In addition to its power, Gmail offers various useful features. Dynamic mail allows you to take actions within emails, such as filling out questionnaires or responding to Google Docs comments. Confidential Mode can set an expiration date for messages and protect them with a passcode. Offline mode lets you access Gmail and compose messages without internet connectivity, though it requires Chrome. While Gmail's free plan has reasonable limitations such as 15GB storage and 500 daily email sends, business or more serious users may prefer Google's Workspace product.
