The vast majority of websites and services require you to use your email address to sign up.
Email addresses are ideal for use as usernames.
They can be a point of contact for normal communication and specifically used for account ownership verification.
Its essentially real-time, so you dont have to wait long for any confirmation messages.
Throughout your life, youre likely to change your primary email address at least once.
Perhaps your email service provider goes bust and ceases operations.
Maybe they started demanding payment or increasing the cost of the service.
Alternatively, you could just have wanted to switch to an alternative provider or change your email address.
Whatever the reason your email address changes, you will have to refresh your accounts email address.
To do so, you should probably be in your account prefs.
To get there, sign in to the Dropbox website.
Once youre signed in, hit your profile icon in the top-right corner, then on options.
In the default General tab of your account configs, press the Edit button for the Personal email field.
Within the change email popup, enter the new email address that you want to use.
Once youve done so, confirm it, put in your password, and click Update email.
