Or how many different ones have you had?

I know that you might only have one,
but I have two, now one as a back-up.

Use to have a Business Email,
but didn't get into it enough after
the business dropped drastically
and eventfully got closed.

3. The yahoo I stopped using. The others are gmail and outlook. I may be making Gmail my primary email for non-business and outlook for business

Sitcoms Online
Comcast
Gmail - I have my first and last name, so I know I'm old.
Yahoo

i used to change them often, getting free versions until they did't xist anymore

i guess 3?

Have you ever got an email from your email, to your same email, that you didn't send?

I put myself in my contacts email.
That way if I do get one,
there may be a good chance that my email account was "hacked."
Even all of your contacts might be getting emails that you didn't send.

2 or 3 I regurally check.....

Just the one. Don’t really need more.
