I was surprised that someone asked me about getting multiple email addresses on my cell phone. What options do we have?
All your cell phone manufacturers have an email application on their phones. In many cases you can add your favorite email application to the phone. Office 365 provides Outlook for your Phone, Android, or Microsoft phone. Yes there is still Microsft phones.
All of the mail applications allow you to have multiple email accounts on them. You can have your gmail account, your business account or even that account that no one else but those special people know about on your phone.
If you want to add other accounts, use your favorite search engine to tell you how to add more accounts.
