Zoho is ads free. It helps you get more of your interface for reading emails and your personal works. The storage is 5GB for emails not unlimited and 1 GB for docs, videos, documents, audios, pictures and files. It does not require fast internet to work on its docs, mails and others as Gmail do. The problem with Zoho is that its themes are just color changes not as beautiful as some others provide. Also the amount of email you can receive per day is limited to 300 mb (with attachment). Although it is enough for normal use but in specific cases it can be really less.
Although the filter are supported but is not as easy to create as Gmail and some others provide.
But over all it's better than most of providers.
