Every ~3 to ~5 years I change my free email addresses (gmail, hotmail/outlook, yahoo, etc.). Although, I don't use yahoo anymore.

I have turned a few of my old gmail accounts into spam mail trawlers as I “Gotta catch ’em all! ” and every time I have to make a temporary or single use account for a service I want to check out/try or I just foresee making only a single purchase I always use a gmail account+alias if they don't have a guest checkout option. The old gmail accounts are checked quarterly on a if-I-remember basis but at least once a year.

On first contact with any business, services or people I have never met in person I usually give a newer gmail address I check biweekly in case my forwarding filter missed something important.

Moreover, I use gmail incoming mail rules to forward copies of important keywords and specific email address to my 2 professional (redundant) emails for which I enabled notification on my phone, main desktop and workplace.

Gmail is so ubiquitous and well trusted that I can pretty much use it in any input forms for registration or verification. Their spam filter is also pretty good (not always) to skip/pre-filter obvious phishing and scam emails.

Even though I have already moved away or avoided Google, Microsoft, Meta/Facebook, LinkedIn, Apple, TikTok, Wechat, Temu, PayPal, Sony, etc. I occasionally still have to indirectly deals with them on a limited case-by-case but specific situations.

By excluding so many excellent email services they are inadvertently making sure that Gmail, Outlook and other allegedly "reputable" free emails services slowly become a junk/spam/marketing email dump that few would want to enable constant notification for and fewer would want to delve into and sift through daily.

Sorry, this became a long rambling rant about all the layer of protections I have to use nowadays to just avoid wasting energy and attention on the profusion of spam/useless emails.
