I’m a millennial - I don’t check my mailbox for 6+ weeks at a time.
If I order something, then I know about it and expect it at my door (because it’s fedex, amazon, or ups).
Otherwise, it will have to wait until I happen to remember I have a mailbox.
For example, with bills - I expect you to have my email address and use it, because I supplied it whenever I established xyz account.
Exceptions:
Around the holidays when people send out holiday cards!
For a local property tax exemption, my county refuses to email it. Their requirement for receiving the exemption is that you live here locally, and part of their way for verifying that, is by sending the request form to your local physical address.
When it's too cold out to wanna walk all the way up there, I've gone for 3-4 months at a stretch. All I ever get is garbage anyway, so it's only ever mattered twice, and one of those was an expected package.
I am almost to the point where I don’t mind normal junk mail. That’s easy to quickly scan, identify as junk, and toss.
What really grinds my gears are when my companies contact me and write something like “Important” on it. This happened recently with my credit card company. I thought maybe I had gone overdue, or had overpaid and this was letting me know my bill the following month would be less (it has happened before).
No - it was letting me know I had good credit and could get a good % on a loan through them if I wanted. Now, that made me mad. Junk mail, from my very own credit card company. B.S.
In the stamp postmark area, if you see "Prepaid Sorted Standard", most of the time it's junk mail like what you describe. Regardless of how "important" it says it is.
I'm like this with email. I do a quick visual scan about once per week... or fortnight... because it's almost all SPAM, and no matter how many blocks and filters I create, it does little to hold back the tide of trash.
Everyone who matters knows the only way to reach me reliably is via text message.
If you live in the US, you can get your mail sent to your email inbox every day you are getting something that is directly addressed to you (i.e., not spam). It's called USPS Informed Delivery.
It doesn't always work if they get your address slightly off (say they put STE instead of APT), but it's a lot better than nothing.
