The concept is good and when it works, it works well and does everything it purports to do but sooner or later I've experienced times when I don't received expected mail and have to try to contact the person I presume is the owner and get it cleared up. Sometimes this can take days since he doesn't seem to take this business as seriously as I take my email service. I've paid for a higher level of service and don't always get it. I created a disposable email address and waited for a confirmation email from a vendor and never got it. Then I tested it by sending myself email from one of my other email accounts and never got it. No guessing the number of emails I've lost during the days or weeks I haven't noticed. If I continue with this service, because I haven't found an alternative YET, I'll probably have to subscribe to a web site that sends daily emails so I'll notice when they stop. But I'll probably just discontinue using it and find another way to avoid spam. What a pity/shame that the owner can't keep it working properly.
Had it been hours, I wouldn't have noticed it; however, the problem was for several days, at minimum, perhaps a week or longer.
