It's a little difficult. If you have type O blood the American Red Cross will bug you incessantly when you're able to donate again. While it's nice to be in demand, it's still annoying. You can ask them to knock it off but there's no option for once a month reminders.

I hate to say it but you are right about this. I donate frequently and encourage everyone who can to do it but the Red Cross spam operation is absolutely disgraceful they have zero shame.

If it works, isn't it more ethical to annoy people in this case?

It's annoying but I don't mind it like I do the daily business loan cold calls.
