I have a few e-mail subscriptions that spam me a lot when I'm not actually using the subscription, but there are times that I'd just like to get all my messages without having to worry about tracking and updating the number of messages that are still available. Is there anyone else out there that would like to be able to temporarily override their limit?
No need for that. That's why there are exclusive and trusted senders. Plus the ability to create all the addresses you might ever need. One per suscription is a good idea in your case.
