Depends on the e-mail address. My main personal e-mail address receives about 5 per day. My other personal e-mail addresses under the same domain receive less. My webmaster e-mail addresses (especially of my big site Talk Budgies) combined receive about 30 per day or more. I have two Gmail e-mail addresses. One receives almost no mail at all and the other I never check. When I do check it there's literally thousands of spam and junk e-mails. My guess would be it receives at least 100 per day. I have no idea how it gets them as I've never given it out to anyone or any website.
