One of the surest signs that business executives are failing their way to the top is that every company you so much as order a toothbrush from thinks it's a sound marketing decision to email their customers multiple times per week, and then when people inevitably "update their email preferences" to tell the company never to email them again, they add more and more checkboxes to the email preferences page and say, oh well you never explicitly told us not to email you about toothpaste, because they only just added the toothpaste checkbox, so now you have to go uncheck the toothpaste box or just start marking all their emails as spam.
And it's not just retailers that do this! If I donate to your nonprofit, why are you punishing my donation with a constant barrage of spam? A few times a year, sure, send out a newsletter that actually has something to say. Anything more than that indicates to me that your nonprofit is dumping my donation into the bloated salary of some C-suite executive that spends half their day watching TED-X videos and the other half driving competent staff crazy by demanding they do stupid marketing schemes that will drive away donors.
