Hate to say this but Gmail is much better than Yahoo. Many simple powerful features such as "label" provided by Gmail help user much more easier to manage the email. I don't understand until now why Yahoo mail does not just copy some powerful features from Gmail to hrlp they improve Yahoo mail.
Yahoo is better in my opinion. I have a paid email account with Yahoo since 7 years ago i guess, and i am okay with them.
I am really attracted by Recently updated features at yahoo mail. It is quite similar in online mail chat, It folder management and draft mail feature make it different to others(i.e. gmail.com). But ........google has its own importance in search engine optimization field. There are several google services to help webmasters......these features make it different from others.
gmail is clean & not much ads as in yahoo... but using yahoo mail is more comfortable for me.. using both them.... a bit more i like yahoo..
gmail only for me. i love the imap feature. talking about notifier ... you are welcome to visit my website: http://www.gmailnotifier.com
I use both but pay $20/yr for the Yahoo Pro email and it is much, much better than GMail. I have just never gotten used to the "conversations" way that GMail organizes email. I also don't like how there is a delay when you type before the text appears. Yahoo email rules. And literally zero spam on Yahoo.
