Before there was Gmail there was Yahoo Mail and MSN Hotmail. But when Gmail came many made the switch.
These are the reasons:
1. Large Storage Capacity
When Gmail came at the scene in 2004 it offered an initial storage space of 1 Gigabyte. Meanwhile Yahoo Mail and Hotmail were only offering 4 megabytes of space during that time. In 2004 Yahoo was promoted to increase the email capacity to 100 megabytes. If I remember it correctly, you have to pay if you wanted additional storage capacity.
The move by Google was significant because email is very vital and space can quickly run out if you frequently communicate through email.
It is such a relief that you don't have to worry about the number of emails you receive and you have a peace of mind that succeeding emails will not bounce back to the sender.
Google has since increased the capacity to more than 7 gig and Yahoo offered unlimited storage.
But it was too late for Yahoo.
Gmail was the first to introduce the use search in email applications. Before you had to go through each email if you are looking for something.
3. Threaded conversation
Gmail neatly organizes email and the corresponding replies into a single thread. This way the emails are organized and you can quickly follow along the conversation in each of your email.
4. Amazing Spam Filter
Google has one of the best spam filter there is. It is really amazing how they do it. Whereas with Yahoo, my emails easily amidst so many spams.
Gmail is very reliable compared to Yahoo Mail that suffered from frequent glitches. There were times that the emails does not reach the recipients for a couple of hours and even one whole day. This has led to some miscommunication and confusion.
But Yahoo announced that they will be rolling out a new email service last May 24, 2011.
The new service promises more speed, organization, and efficiency.
We will find out in the weeks ahead.
