A couple of helpful thing to know is that gmail ignores periods within email addresses, i.e.
discountwigoutlet@gmail.com
and
discount.wig.outlet@gmail.com
are the same in Gmails eyes.
Gmail also ignores anything you put after a
+
symbol and before the
@
symbol. For example, you could use the address
discountwigoutlet+freenas1@gmail.com
, and then filter and catogorise, and tag all the emails addressed with the
+freenas1
address. You could then use
discountwigoutlet+freenas2@gmail.com
for your 2nd freenas server you might be using to run your discount wig outlet business.
This also works on many websites, when creating accounts or signing up to newsletters. But a word of warning, I said "many websites" for good reason. Not all websites support using the
+
symbol and as such, it can cause issues. So if you use it, make sure that it's acutally working and that you're recieving mail from the website / newsletter in question.
[EDIT] It's also worth mentioning Google's App Passwords feature, which is great for when you need to use your email for an app or for email reporting but you don't want to use your Google account's actual password -
