It’s weird, but that’s been my experience too. I switched off Gmail (where I got tons of spam, although most properly caught by the spam filter) several years ago, and have received fewer than 200 spam emails in total since switching. I know this because my new host won’t allow the personalized spam filter to be enabled until you’ve received 200 spam. I’m not at all careful to keep my email address hidden on the inte…
Eventually you start getting a bunch of spam. I feel most of mine originated from GitHub and data-leaks. Tip: configure a catch-all to your email address, and use custom email addresses for every website. I love having e.g. news.ycombinator.com@gilani.me and being able to filter out bad email addresses whenever they become tiresome. I've also configured Mailgun on the domain (not what it was intended for but ¯\_(ツ)_/…
My GMail spam folder has around 10-15 messages in it per day. My inbox is nearly always fine. The nice thing that GMail does is sort promotional emails that it doesn't judge to be outright spam under the "Promotions" category, which I don't see unless I seek it out. That one still isn't that bad, on the order for 10 per day, but it is genuinely stuff I don't care to see.
If I were to move away from GMail (which is on my todo list), I'd have to figure out what to do about those. Likely they mostly have unsubscribe links; after a quick scroll down the list, I think it's nearly all from companies that I do have or had an existing relationship with.
I wish GMail had an "unsubscribe" button so I don't have to hunt through emails for their often-hidden unsubscribe link. Yes, I could click Spam and then "Unsubscribe + Mark Spam", but I really want just "Unsubscribe", but that's not an option.
I do have a fairly uncommon last name, so it's not something that spammers might accidentally put in a word list to use as an email domain, but overall I've just mostly not cared about "protecting" my email address, and it's mostly not been a problem. Is this entirely atypical? If so, I wonder why...
