SEORoundTable writes that Gmail has bumped up it’s capacity to 6 Gb.
Google’s Gmail actually set the bar (and killed a few web based email services while they were are it) by being the first to offer 1Gb of mail storage a few years back. At that time access to Gmail was by invitation only.
Yahoo! Mail, which had about 10Mb at that time also followed suit. Last May Yahoo even started offering unlimited email space.
Along with that December feature upgrade, Gmail also added colored filtering tags which can make mail sorting a whole lot easier. And if you have friends at AIM chat, you can now chat with them via Gmail. Plus a sling of keyboard shortcuts to make your emailing experience more productive.
