Maybe if your Gmail mailbox is really populated with so much mails, then you will definitely need more spaces, but as for me, right now I think my mailbox is doing just fine, just try to arrange or check your mails. Delete some mails that are not really important.
The present capacity of gmain inbox is too huge but it's smaller compare to unlimited of yahoo. But for me gmail is the best free email because of less spam mails.
What? Gmail does not need more space , its growing constantly , i always have like 1500+ spam and 3558 inbox emails and look: You are currently using 104MB (1%) of your 7355MB.
More space? I really don't know why would you need more than 7GB for email? Unless you think of uploading movies on it.
No, more space isn't needed. Delete e-mails you dont need. 7 giga is much, what do you have in your mail box that takes so big space? :S
No way should you require more space for a freebie mail service. If you do, then you need to get a business standard mail service that is designed to cope and handle professional or business quantity mail.
