It's easy to use, fast, and keeps my emails organised. I love how I can access it from anywhere, whether on my phone or computer. Plus, the spam filter is top-notch, keeping my inbox clean.
Gmail is good but it has some huge usability issues.
Reply all need confirmation.
If you use multiple emails in one Gmail it doesn't act smart and the reply uses the default email, not the email you originally sent which is painful.
Organizing it is not easy and friendly.
It catches many wrong things as spam.
