Having multiple email accounts is a popular strategy with Internet users today. If you have
just one email account through which you receive all your electronic communications, you
might understandably be thinking that juggling two or more would be way too much work.

But splitting your Internet communications over different accounts does have some very real
advantages:

You can cleanly separate your communications based on importance, usage, or
some other broad metric;
You can isolate your communications so that if one of your email address is
hacked the hacker doesn’t get a big picture of all your contacts and online
services you use;
You can funnel any services that you expect will flood you with spam or sell your
information into a different email inbox that you can largely forget, without the
need to set up complex filtering rules;
If one of your email addresses is hacked and you have to abandon that email
address you can quickly switch to one of your other addresses (which is useful if
your email address ends up on a sucker’s list);
Perhaps surprisingly, two or more purpose-driven email accounts can in fact be
easier to maintain than a single all-purpose account.

To summarize the above points: using a single email address for all communications is akin
to putting all your eggs in one basket.
One very popular strategy today is to use two email addresses: one for ‘junk’ mail, and one
for ‘important’ messages. Some people have several unique email accounts! One for friends
& family messages, one for social media networks, one for online services, etc.
How you decide which contact goes to which email address is up to you. But the multiple
email account approach is a tried-and-tested approach that millions of users now use. And
cheap or affordable web-based email services make it pretty easily to set up.
