There's no such thing as "double opt-in."No, I didn't. One denial occurred in 1995 or 1996 and one in 1997, so subscription was single opt-in. As to the present, the list's topic became obsolete in 2000, so it has been closed for more than two years now, but if it were still in operation, I would use double opt-in and keep the confirmation.
A request from some unknown location comes to you. That's not an "opting in" because it is unverified that that is actually the target person opting.
You send out a request that the person whose address was the target confirm the request.
Their reply to that is the *only* "opting in." Anything before that is a random piece of data submission.
Calling it "double opt-in" accepts the spammer thesis that any address they capture by any mechanism is an initial "opting in."
