I discovered that when you delete your email address for a week almost all the spam and newsletters disappear. I don't know exactly how it works, but it does. So every couple years I just completely disable my email address for ten days, or whatever, while on vacation.

Everyone who sends email has to be very careful about upsetting email service providers, because they'll mark your messages as spam if they suspect you of misbehavior. Email providers use many metrics, and one of them is the number of bounced emails.

It doesn't take much to be marked as a bad actor, so companies will quickly remove you from their lists if you're jeopardizing their ability to get into the inboxes of their other users.

Source: I've worked at a couple of companies that used email as a significant part of their strategy to keep in touch with users.

Very true. I've used SendGrid and Mandrill for transactional email services and bounces count against your account's reputation.

Most of them will require warming up the account/IP you're sending the emails from in order to increase the quota of emails you can send per hour/day.

I don't know how spammers work, but legit mailing list software/providers will remove an address after a number of soft or hard bounces.
