The advantages of having a web-based email (from now on I will use GMAIL as that is really what you want), are so many but to name a few;
- Accessing your email from any device (tablet, phone or computer)
- From anywhere you have internet connection
- The email address is yours for life (or the life of Google, should you outlive them), unlike your internet provider email, the moment you opt to switch to a different provider because they have a better deal or you move out of town from the existing provider, the moment you quit their services is the moment you lose all of your email access to that account.
- The best email spam filtering available (Gmail)
- Having a Google (Gmail) account allows you to take advantage of chrome sign in which will save your settings, bookmarks and more.
Do I really need to say more? I think not.. other then to contact me if you have troubles setting up your new gmail account which you can do from this link.
