Email is here to stay.
There are numerous apps or programs to view email and depending on your mobile phone, ipad, tablet or desk top computer, some are better than others.
Do you have multiple email addresses? Some people have a different email address for work or home. I recommend using more than one address. These days one is required to register online for purchases or some reason. If you have an address for infrequent use, it can make it easier to manage spam or private communications.
I use Yahoo and Gmail free addresses. What program is best to view the email? I have used MS Outlook at home on a computer and work and found it is quite powerful and practical. I don't like MS license subscription style of expense, so I looked for the free programs. I have found a few but currently very happy with Bluemail. It manages multiple email addresses easily with a unified inbox, so you don't miss anything. Some phones have built in email programs like Apple or Samsung, and they work quite well. Bluemail does work on any device.
