If you ask me what is my favorite webmail, I would say Gmail. It is very cool and fast, and has a clean interface. It is my main email account. I am loving Gmail, and here is why.
1. Spam control
Yup, Gmail automatically throws mails which seem to be spam to the spam section. Furthermore, Gmail deletes spam mail after it has been stored in the spam section for 30 days. Therefore, I don’t have to delete spam mail manually. Though, it has a ‘delete all spam’ button.
According to Wikipedia, this is how the spam filter works
“Gmail’s spam filters include a community-driven system, where emails marked as spam by one users provide information to help the system block similar future messages for all Gmail users.”
